This challenge seeks an innovative design for a brick connection into a collection cavity that is reliable, has a watertight seal, is quick to connect and can be retrofitted into current assemblies. An effective seal is critical to the success of well-designed industrial components and their broader systems, and a faster connection will expedite the manufacturing process.
The physical and digital worlds are converging, ushering in a new age of manufacturing and industry. New manufacturing methods through advanced manufacturing, fabrication and additive applications are redefining traditional constraints—making what was once impossible—possible. These advancements proliferate across industries and the entire manufacturing value chain —allowing for redesign of key parts and components that are the building blocks of broader systems. Thereby, the innovation designs that maintain quality and performance while accelerating assembly processes through the creation of a simple part can have a ripple effect in the manufacturing improvement across global industrial systems.
The designs submitted will be analyzed and evaluated by a panel of at least four (4) judges at GE and the up to five (5) designs will be selected for awarding from a total prize pool of $10,000. The winning entries will best satisfy all of the requirements, are suitable for mass production, simple and reliable.

Good afternoon
It will be possible give me example pictures of the actual product or a example that have in the market?
Many thanks Ricardo
Devin Sidell over 10 years ago
Lisa,
Can you help to explain a little better what this is exactly? The diagram is blurry.
Lisa Ralph over 10 years ago
Hi Devin,
Great question! The full-sized diagram (Figure 1) is actually available as a PDF (also, same in the CAD model), which can be accessed by clicking on the "Download Specifications" button at the bottom of the "Requirements" section. The PDF will show a few views (Section B:B and Section D) that should provide a little more clarity.
Please let me know if you have any additional questions!
Many thanks,
Lisa
Attila Tarjan over 10 years ago
Hi Devin,
Please try to download the specification. This is a simplified version of a product feature where we are looking for quick connection and reliable sealing inbetween, as described in the technical requirements.
Regards,
Attila
Attila Tarjan over 10 years ago
Hi Ricardo,
We are looking for a solution how to connect and seal the two parts which will operate in the described environment. As we are looking for a technical solution product is not so important and we did not plan to share. I will be happy to answer all questions related to technical requirements and functionality.
Regards,
Attila
Attila Tarjan over 10 years ago
Some additional explanation to the challenge:
Please consider this as described, simple. There is a brick which have to go into the cavity and they have to be connected (see 3D and part description: Urethane brick with injection molded cavity). We are looking to find a reliable technical solution to connect them and define sealing in between for the described conditions (technical requirements, water tight, pressure 3bar…). It can be any kind of connection. Mechanical connection with extra designed features or adhesive… all that works. Contesters can modify both geometries, given in 3D, except the features that are dimensioned on the drawing, for them we are looking to be fixed if possible.
Looking forward to answer any upcoming questions.
Regards,
Attila

kip gunter over 10 years ago
the 3d model appears to be one piece when opened, can't separate the connector
maximiliano ancharek over 10 years ago
Hi everyone!! just some questions.
-What is the purpose of this connection? must be capable of operating on a machine? in a vehicle? in a building?
-How you compare the ability of either a permanent or removable junction? how this affects the desicion of the best design?
-This is just a plug? or is an electrical connector? Hydraulic? pneumatic?
-should be possible to remove using common tools? using special tools or just with the hands of a person?
James over 10 years ago
I was excited until I saw the following technical requirements and Judging criteria:
Technical requirements:
6. Expertise and capabilities of Entrant. Share your experience and expertise, discuss other work of a similar nature, highlight other capabilities or competencies.
And:
Judging criteria:
6. Entrant’s capabilities and experience.
I think the contest should be open to anyone who can produce a good design. Shouldn't the contest be judged on the design merits alone? Why would anything having to do with the personal aspects of the designer have any to do with the actual design?
Looks to me to be a contest of who has the most spectacular credentials rather than who can come up with the best design. Not very inviting. :)
Robert Dietz over 10 years ago
I'm not sure what a "brick" is. Is it an interface? Perhaps a picture of one installed may help. The diagram says the skinny side is the bottom and the open end is the top. Seems if the bottom is sealed and the top is open it would fill with water and freeze thus cracking the housing.
Attila Tarjan over 10 years ago
Dear Kip,
You should see 2 separate parts in the 3D, brick and the cavity, it is an assy in step format. Please give me some details how it opens in your cad software.
Attila Tarjan over 10 years ago
Dear Maximiliano,
Please read the technical requirements above, they are complex I have to admit but due to project sensitivity we did not wanted to reveal more. There is Urethane block that have to be connected with injection molded cavity and have to be sealed off from the environment.
Please try to think about conceptual solution first then go into the details. If it’s permanent or removable connection it’s a minor difference. Important is that it have to be quick and reliable.
Please see my “additional explanation” post, I hope it clarifies what we are looking for.
To answer your questions: Purpose of the connection and sealing is to ensure operation of the product under water and be able to take the inside pressure of 3bars, and cyclic pressure of -1,1bar (see the pdf). The pressure forms under the brick inside the cavity. Permanent connection is for example if you glue them together, removable if you bolt with some additional features. Both are acceptable if they are “quick”.
About needed tools or manual disassembly both is acceptable.
Regards,
A
Attila Tarjan over 10 years ago
Dear Robert,
Brick is a part of the product that has to be connected to the cavity. It’s made of urethane as it is described, I cannot reveal more than this. Where to place the sealing and the connection is totally open and up to you in this case, some guidelines are shown in pdf. Generally we are open to any solution it has to be quick and reliable seal the -1,1 bar with max 3 bar pressure.
Feel free to ask more.
Regards,
A
Alberto Beretta over 10 years ago
Also I understood very little of what you have to design
Attila Tarjan over 10 years ago
Dear James,
This challenge is not just about 3D design but we are looking for a full technical solution to connect and seal this two parts.
Expertise and capability of the entrant will be recognized by the submitted solution backed up with evidence that it works. Entrant need to have a certain expertise to be able to submit calculations or some kind of evidence that his solution works. This is covered with the two items you mentioned.
Looking forward to get a solution from you.
Attila Tarjan over 10 years ago
Dear Alberto,
See my comment above "Some additional explanation to the challenge ".
I am available to answer any questions you might have.
Ivan Pankratov over 10 years ago
Dear Attila,
-The pressure inside the cavity is biger than outside?
-What do you mean by -1.1bar cyclic pressure? Does that mean that pressure difference between inside and outside the cavity oscilate in the 1.9 - 3 bars range?
-Do you have additional loads on the connection beside pressure loads?
-Is it acceptable to have some additional equipment needed for assembly (glue tube, special tools)?
kip gunter over 10 years ago
When I open the 3D file I can see the two parts, but can't select or separate them I use Rhino software
Attila Tarjan over 10 years ago
Dear Ivan
All works few meters under water.
Cyclic pressure means that it can be above or under the environment pressure. We pump or drain fluid (with vacuum) into/from the chamber. Additional loads are not significant at his stage, you can calculate only with the pressure.
Any equipment or even additional part is acceptable (if the requirements form the pdf are kept).
Attila Tarjan over 10 years ago
Hi Kip
Unfortunately I do not have any experience with Rhino… I use Solid Works when I import the step it recognizes the assy and both parts. They are editable. Any possibilities for you to open in other CAD software?
ANOUAR BARODI over 10 years ago
@ Kip gunter: When you open the stp file with Rhino, you'll Object name: Quick connect assy 12F
Layer name: Default
Select the object and then Click on explode once and so you'll have the two objects, good luck!
Ivan Pankratov over 10 years ago
Dear Attila,
Thanks for answer, i think i've got it now. )
Gerard O'Donoghue over 10 years ago
The challenge seems clear enough, there is a plastic brick shaped object, it fits inside a plastic box shaped object, seal it so it does not leak and fix it so it does not fall out. Come up with a quick and clever concept that will be easy to do, worry about the details a bit later. Am I missing something here?
Attila Tarjan over 10 years ago
Hi Gerard,
Yes this is the good approach to start with. Next step is to refine the concept(s) you have, for final submission we would like to get some evidences that the design works, can fulfill the technical requirements (consider the given materials, working environment, pressures, dimensions etc...)
Robert Dietz over 10 years ago
You mentioned to Ruad that " One detail is not fulfilled is to keep the footprint (if possible)"...I don't see that in the specs, my locks protrude slightly, I suppose I can shave them down?
Robert Dietz over 10 years ago
On a side note 3 bar represents 10 feet of water according to my calculation, so I should be able to simulate the seal in tub of water at a depth of 10 feet. Is that correct? (at sea level)
Attila Tarjan over 10 years ago
Hi Robert
It’s mentioned in the tech requirements that part must meet dimensions form the pdf. The 49+/-1 should be ideally kept unless there are no other solutions.
Pressures from -1 to 3 bars represent the pressure differences between the chamber in the cavity and the environment (see “detail – D”). Due to this loads from the inside pressures will have different directions.
christopher curl over 10 years ago
Robert Dietz, It is closer to 100 feet. 1 bar is about 14.7 PSI (1 atm) good basic number is 44 PSI/100FT of water.... 3 bar is about 44 PSI which is about 100 ft. exact number is 100.3657 feet
Francisco Hernandez over 10 years ago
Seems like a lot of people were confused by the general description. I think I understand it but still have a question. The BLOCK is made up of 6 part models in the assembly. Is this correct? Is there a reason why there are 6 different parts?
My 2 cents: By asking people to provide proof and calculation it withstands pressure requirements you are narrowing your pool of people to Engineers. Might have been more beneficial to explore different attachment/sealing methods and having your innovation team experts improve upon those rather than asking for a working solution based on a general description.
Sean over 10 years ago
Attila, I have four questions for you:
1. "Cavity ideally one piece but can be made out of two or more;" This is unclear. What do you mean by this? The existing cavity is already one piece. So are you talking about additional pieces? Or a cavity used to manufacture the urethane parts needs to be a one cavity tool?
2. I am seeing the "Brick" as six separate pieces when importing into SolidWorks. Are the six independent parts of the Brick assembly free floating components that we need to hold together, or is it actually one solid piece?
3. So we can modify the geometry of either piece except for what is shown in cross section B-B correct? So can I modify other surfaces that aren't marked? You specify surfaces for adding features for fixation that are only on the interior of the cavity. Can we add features on the outside of the cavity that aren't marked either way or at all?
4. Is cost a factor? Or is this just the "best" technical solution? If cost is a factor, can we know approximate production quantities?
Thanks,
Sean
John over 10 years ago
I have a little suggestion for this forum:
The whole world speaks English, which makes it very easy for Americans to communicate with everyone else on the planet. No real need to ever learn a second language, right? And except for the USA, the whole world uses the metric system, and has been doing so for quite some time now.
It would be a real courtesy for Americans to stop using those "US Customary Units" when communicating globally. After all you guys no longer speak Shakespearean English? So why would you insist on such an archaic system of units, which even the UK and British Commonwealth have given up.
Sorry to be so blunt, but I hope you get my point.
Peter Cosgriff over 10 years ago
Hello Attila,
I appreciate that your project is confidential in nature, however if you could answer the following questions it would assist:
1. The environment the unit operates in is defined as water. Is this salt or fresh water?
2. Material for brick is currently cast urethane. Can you specify the hardness (duro rating) of the urethane? Is the brick flexible or rigid? If flexible, is the material soft enough to act as a seal? Is the core of the brick designed to move or oscillate within the cavity when the pressure changes (does the pressure drive the brick in and out)?
3. The medium being pressurised within the cavity. Is this in a liquid or gas state? What is the operating temperature of this medium?
4. The cavity has a port at one end. Should sealing of this port also be considered in the concept, or are you only seeking ideas for the interface between the brick and cavity?
5. Overall length of cavity/block assembly is not defined in the drawings, therefore this can be a variable? Can you confirm the max/min value for the length. This can have an effect on pressure calculations, seal sizing etc...
Best regards,
Peter.
Louis Brillon over 10 years ago

Better quality images??
Lochlin Black over 10 years ago
Can we please have some more information on the material properties of both items? Trying to run a basic FEA to ensure it meets specification.
Attila Tarjan over 10 years ago
Hi Francisco,
Brick is one part only, geometry is defined on the pdf drawing.
Related to proofs, I agree with you that all contesters should focus on conceptual solution(s) in the beginning, but we would like to encourage the entrants to check the details of their designs and submit a working concept.
Lisa Ralph over 10 years ago
Hi all,
Just as food for thought—please remember, this is a design challenge that will be evaluated based on technical merit.
The “background and expertise” is just a way for us to learn a little bit about you and holds extremely low weight in the evaluation process—so please do not be discouraged by this. We are always thrilled—and often see—that winners of our challenges have very little experience in the field at hand—this is more a tip of the hat to the power of cross-pollination of expertise and diversity of application.
We are truly looking for the best design—not the best resume. There have been some great conversations here and I’m very excited to see what this community dreams up!
Lisa Ralph over 10 years ago
Hi Bailey--good question! The full-sized diagram (Figure 1) is actually available by clicking on the "Download Specifications" button at the bottom of the "Requirements" section. The PDF (and CAD model) will show a few views (Section B:B and Section D) that should provide better quality imagery!
Attila Tarjan over 10 years ago
Sean,
1. With this we open the possibility for the concept, you can use a cover for example to close the cavity and seal…
2. Brick is one part only. You have to connect it with the cavity and seal. (See the pdf)
3. Fixed is only what is dimensioned in the pdf, there are suggestions where to seal or add additional features. Outside of the cavity has the 49+/-1 should be that ideally. If something needs to hang out should be minimal.
4. Cost is a factor but In the concept phase it would be difficult to tell … quick connect and reliable seal are much more important.
Attila Tarjan over 10 years ago
Hi Louis,
Brick corners can be rounded if you keep the part width and length as on the drawing
Attila Tarjan over 10 years ago
Hi Bailey,
There are better images in the specification. Please download.
Attila Tarjan over 10 years ago
Dear Lochlin,
Cavity is injection molded plastic, not specified, so you can go reverse and define material based on loads. I will get you typical data on urethane (brick) soon.
Attila Tarjan over 10 years ago
Peter:
Good questions!
1. Its fresh water.
2. Its poly urethane, rigid, fixed, pressure defined detail D -1,3bar so it pushes it out or pulls it in. I will get you some typical properties.
3. Its liquid, temperature in the tech requirements: 0-40C.
4. Port is not important for this challenge.
5. Overall length based on 3D ~500mm, It can be modified a bit (+/-5mm.)

Alten Claassen over 10 years ago
Attila
One thing that baffles me, well actually 2, are
1. Why the large gaps between the cavity inner wall and the brick's outer walls on the "back"?
2. Why does the brick have steps on the seemingly not so important "back"?
With that said, I haven't seen anything in the specs that those features can change (to be quite honest I did not read in too much detail), are those features adaptible to make material use less and to ensure minimum dirt and grime growing/accumulating in the back that might cause it to not release when you need to open it? Will the brick be mechanically inserted and removed, therefore requiring the space?
PS: I like the secrecy hopefully not to be used in some doomsday device, hehehehe
Will Montgomery over 10 years ago
Is it me, but can I have an ideal of what its used for? I mean how important are the gaps? What are we sealing an electronics package? It is left that you want exactly what you have, but a sealing system that allows for dis-assembly later?
Conrad over 10 years ago
Hi Lisa, Is there a reason the zip file does not contain data for the step file? Or did i extract it wrong. i used win7's extract function. The zip file contained "Quick Connect - Figure 1.pdf" and "Quick connect assy 12F.STEP". the step file is an assembly with no contents? I use SW2015 to open step files.
Attila Tarjan over 10 years ago
Hi Alten,
1. The submitted 3D is a schematic reflecting the current product going into this challenge we could not predict all situations or needs that may come. The free space between should be used for adding the sealing and connect features, you can make it smaller or solve this by adding features into it as written in the notes. Important is not to go above 49+/-1mm.
2. Steps on the brick represents some functional areas, as a guideline for connect and sealing there are notes on the drawing showing which surfaces are good or not good for connecting and sealing.
Eventually we will need to solve the gap between as you said to avoid any accumulation inside, however in this stage we targeted to get connection and sealing concept, but if you solve all that it’s even better. If you have something specific on your mind we can discuss it.
Attila Tarjan over 10 years ago
Hi Will,
Even if you knew what this is you would still have to deal with the items listed in the technical requirements. We are aware that this makes it more difficult to solve but unfortunately we have to go like this.
It works under water, has to be connected quick, sealed reliably for the mentioned pressures. Connect can be permanent or removable focus is on reliability. Keep the tech requirements.
I would encourage you to submit your concept based on this.
Tomica Vukovic over 10 years ago
Challenge is good, but strictly specification that connector must be brick is totaly foolish. According my experience best shapes for gas or lquid sealing is concentric or eliptic and securiting with threads or cllamps even to be quick connecting.
in this manner forget brick model and transfer your minds to eliptic model(rules of strenght and deformations will prove this decidion)
Stay well
Attila Tarjan over 10 years ago
Hi Tomica,
We have some geometrical limitations unfortunately, but as the length is not fixed but you may round the edges for the needs of the sealing.
Attila Tarjan over 10 years ago
Peter, Lochlin,
You can use the following mechanical properties for the urethane:
Tensile Strength 40MPa, Young modulus 2000MPa
Lisa Ralph over 10 years ago
Hi Conrad,
If you click the "Download Specifications" button and download the zip file--try unzipping the file first and then opening in your CAD software after--hopefully that should work!
Abdelmoumene over 10 years ago
Hi,
1-Please, explain how we have a 6 volumes in the bricks part?
2- Inside the bricks part, is it empty or full? can we add somme composants inside?
Attila Tarjan over 10 years ago
Hi Abdelmoumene
Brick is a solid part. Inside cannot be used for adding features. For that you can use the space between it and the cavity.
Multiple volumes appears due modelling method to represent the outside geometry.
ruben_s over 10 years ago
To Attila Tarjan
Derived from Quick_connect_assy12F.step file:
1. Inner surfaces along long side of the cavity are drafted.
2. Inner surfaces along short side of the cavity are parallel to each other.
Is this means that inclination of inner surfaces depends from cavity's axis direction?
Enrique Basora Sotomayor over 10 years ago
is there a specific material for the cavity or can i choose?
Ernesto Chavez over 10 years ago
Enrique,
The requirements say that the cavity is made of injection molded plastic.
Attila,
What injection molded plastic in particular is the cavity made out of?
neomechanikos over 10 years ago
Requirements state that the materials must be compatible over the temperature range. But should temperature change (delta of 39C) after sealing be considered for pressure as well? This could be quite significant.
Attila Tarjan over 10 years ago
Hi Rsahak,
Drafting is just for example, you can change it as long as you do not go out from the width 49mm.
Originally we would like to use this surfaces and this gap between cavity and brick to add the connection and sealing features.
Attila Tarjan over 10 years ago
Hi Enrique,
Material is up to you; have to meet the technical requirements.
Attila Tarjan over 10 years ago
Hi Ernesto,
Not specified, should be chosen to meet the tech. requirements.
Attila Tarjan over 10 years ago
Hi neomechanikos
The operating temperature range is 0-40C for the whole assembly. Its uniform, the whole assembly will take the temperature of the environment. What need to be considered is the thermal expansion of the used materials to ensure hold and seal on 0C as well as on 40C.
Amol Baykar over 10 years ago
Can anyone explain me what to do in this challenge in simple language???
Lisa Ralph over 10 years ago
Hi Amol, this challenge is essentially asking for you to design a brick that connects with a collection cavity to create a watertight seal (for example, the brick might "snap" into the connection)... we're looking for things like a simpler design, the ability to reuse the connection (instead of, again, say, being permanently snapped in place) and of course being able to still be as reliable in terms of a long lifespan and maintaining a watertight seal.
geo over 10 years ago
Hello Lisa,
with you, I would to share my dental braces.:)
I think a plasicpart, 500mm, 3 bar and tightness is not easy, but possible.
You write "a snap".
Perhaps a 500mm long plastic-stripe like a half fischbone.
One side smooth, one side bone.
One direction for mounting and remove, the ohter direction to spread and snap.
I hope to find next days a good solution.
Lisa Ralph over 10 years ago
Thanks, Geo!
To all--"snap" was just one example... we are interested in any and all designs you think might work--one that slides, something that screws together--etc.
This community if full of brilliant design minds--so as long as it connects (in whatever way you think is best)--and is watertight--we are excited to see!
Lisa
#David over 10 years ago
I like this challenge, but up to this point have found it a bit difficult to test a design (the concept stuff is easy) along with my other challenge entries and day job obligations. However, I'm never one to disappoint a pretty lady and may just have to make time to put something comprehensive together ; )
Jonathan Brazeau over 10 years ago
always on the top of my list anytime I do a complex engineering challenge involving physics, math and geometry, impress the ladies.......lol.
Ernesto Chavez over 10 years ago
@GE, two questions:
1) For the -1 to +3 bar pressure requirement, are those supposed to be gauge pressures or absolute pressures?
2) For the 1 to 40 degrees centigrade requirement, is that supposed to be the temperature range of the fresh water environment that the cavity+brick assembly will be operating in, or is it the temperature range of the actual medium that will fill the pressurized area below the brick?
Lisa Ralph over 10 years ago
You guys are great! Loving these designs!

Attila Tarjan over 10 years ago
Hi Ernesto,
1. The -1, +3 bar is the pressure differences between the chamber and the environment, see detail D on the drawing.
2. The whole assy will have unified temperature in the given range.
Attila Tarjan over 10 years ago
Hi Ridwan,
Limitations for the brick are given on the drawing. It’s a solid, cannot used the inside volume. You would need to take care that assy fits in width of 49+/-mm bricks dimension 33,8 is kind of minimum you are allowed to make it wider towards the cavity walls or add fixing features to the sides as it is suggested on the drawing section B-B.
Gerard O'Donoghue over 10 years ago
@#David, I think that is why they call it a "Deadline". Makes it more of a challenge.
#David over 10 years ago
@Gerard, just looking out for the folks at GE as last I checked they were the ones paying. If they're fine with doling out 10 grand for 60-70 entries, so be it. The Cleveron folks (like many others have done in the past) extended their deadline another week and were able to more than double the amount of entries. And, in my opinion, obtain a much better set of usable Intellectual Property at a decent price, which is after all, what this is really about in the first place.

@#David, The folks at GE set the deadline. To be fair to the engineers who get their entries in by the due date, the deadline should be maintained in my opinion.
.
As long as some engineers Do Not stay in the background and let the ideas flow and then come in at the eleventh hour with a combination of the best ideas, a 3D model printed and a video of the assembly and testing..... edited and complete.
www.grabCAD.com......could become....... www.grab-visit-my-workshop.com
.
They should make a sketch showing their idea and send it in.....EARLY......LOL
.
But...extend it if they want to...no problem.

@Gerard. You've missed the point entirely.

@#David, We shall see :-)

Hi, I updated my model. Added analysis result under the 5 bar pressure. Added mounted section picture. Please Check it. FNDK Quick Connect

I can't quite figure out if staying up all last night working on my challenge was actually for a chance to win one of the cash prizes...or just to impress that pretty little lady from corporate. Definitely begs a question about incentives ; )

I did not include a rendering so there is a default image displayed. Is it possible to add a rendering file to the package. Thanks!
Lisa Ralph over 10 years ago
Hi all! SO AMAZED WITH ENTRIES!! This is an incredible race to the deadline this evening!
Lisa Ralph over 10 years ago
Kirby, I think the submission "dropbox" should let you add one in. If not, feel free to resubmit the entry and we can swap them out during our review. Thanks again!

Someone unplug Australia from the internet please

Lisa,What size to submit the renderings to look nice and fit in the view?
Lisa Ralph over 10 years ago
Hi Conrad, as long as it's large enough to see and read the detail accurately--we're happy with whatever works best for you--no restrictions!
#David over 10 years ago
Not sure what happened to the original IGS entry file I uploaded, but it's back up there now - fyi

lol @ Davids comments.... how much do you want to bed she's married already :)
Jonathan Brazeau over 10 years ago
lol @ Conrad... SO many options! that's the way to do it, spam your designs until they cover the whole page! How could they not pick one!

I believe a flange style fastening system is the solution. It takes a lot of mechanical force to make a pressurized seal and the plastic will distort if not evenly applied.

Finalist Update: We thank everyone for your participation in this Quick Connect Challenge. We are pleased to report that the Judging Panel is on target with its review of the numerous Entries and is at a point in the internal selection process where it has narrowed down the Entry submissions to a pool of finalists. The internal evaluations will continue in accordance with the Official Rules and the Challenge Winners will be announced on June 8th. We look forward to the results!
Kamen Rusev about 10 years ago
....and the finalists? Where are they?
#David about 10 years ago
I've been wondering the same thing. The "official rules" mentioned by Ben above state that the finalists will be announced by April 6th. He also mentioned on April 5th that the judging panel has "narrowed down the entry submissions to a pool of finalists". So again where are they? Have we missed something?
Ben Ewing about 10 years ago
#David and Kamen Rusev, in the case of this challenge, we will be releasing the finalists and winners at the same time on June 8th. This will provide the judges with time to conduct extensive testing on the entries. When the winners are announced, the selections will be thoroughly explained.
On April 6th, we wanted to update the Community and let all of the entrants know that the process is on schedule and that the judges have begun to narrow the field. Sorry for the confusion!

The winners have been announced: https://grabcad.com/challenges/ge-quick-connect-challenge/results. Congratulations to the winners! There were so many unique solutions for this tough, technical challenge. To pick the winners, the judges took an in-depth look at how each finalist stacked up in terms of suitability for mass production, simplicity of design, estimated reliability of the seal, ability to connect quickly and the potential to remove the connection. Thank you to everyone who participated in this exciting challenge!

although defeated admit that winning works are great.
In my project I had a privileged cost of the injection mold as much as possible reduced.
Honor and good wishes to the winners

@ geo
Very often the logical paths are similar, and this kind of devices belong to my work background on pressure vessel as you can see from my portfolio.
I can assure you that while I drew my model I had not yet seen your model.
Thanks anyway for the fairplay.
Congrats to other winners!

@ Flaviano
You are a good man and have good feeling for design.
I'am not angry to you. :-)

Thanks to GrabCad and GE for making these arrangement and all the excitement. Also for Ben and Lisa that were able to keep the spirits up and making the challenge enjoyable. It is great to see the power of excitement and creativity at work, because the Almighty made us very able designers - and for that we are grateful.
