Show off your skills and solve real design problems
The objective of this Challenge is to create a filter housing for in-line fuel filters that don't collect air or other gases during utilization. These filters will be place before pump (suction side of the pump). Fuels (gasoline or diesel) always contains more or less gas (air) bubbles what can fill the filter housing over some period of time and eventually prevent the fuel flow.
DESCRIPTION OF THE PROBLEM
These filters will be placed on the suction side of the pump. Fuels (gasoline or diesel) can contain different levels of gas (air) bubbles that, over time, fill the filter housing and may eventually prevent the flow of fuel. In order to get rid of the air pillow after it has formed, the filter housing has to be opened up and manually refilled with fuel.
THE OBJECTIVE
The objective is to create a filter housing for the filters described above. The housing must be designed in the way that air-pillow formation is avoided or at least it doesn't present a problem for fuel flow while these filters are almost exclusively used on the suction side of the pump. The placement of the filter is before the pump.
Since the filter housing has to be safe, it should be designed with the following considerations:
- made from metal (corrosion resistant steel/aluminium), plastics can be proposed if they gather no static electricity, don't degrade in contact with fuels and is not subject to thermal failiure
- easy to manufacture
- easily serviced (if possible, make it serviceable without having to remove the filter)
- connected using pipe threads (either NPT or BSP)
Models can be done in any CAD software as long as STEP or IGES files are also uploaded.
Tag your model with “filterhousing”. Only entries with valid tag will participate!
ADDITIONAL INFO - WORKING PRINCIPLE OF THE COALESCING FILTERS
Please take a look at the video
PLEASE NOTE THAT ALL THE ENTRIES HAVE TO BE PRIVATE. SEE RULES AND PICTURES BELOW FOR MORE INFORMATION.
The solution must be based on the following technical data:
- Filter dimensions ∅146 X 452 mm;
- Flow rate 50 l/min;
- Minimal distance between filter housing and exterior of the filter element 70 mm.

is the filter size 165mm dia x 300 as above , or 145mm dia x 452mm as in PDF ?
Tanel Välja about 11 years ago
Hello Aleksandar - yes, that is correct.
Ken, I also added IGS,STEP and Parasolid files into the specification. The filter size should be 146x452mm as in the PDF.

I think - I'm in :)
Tommy Mueller about 11 years ago
Bringing in a collaborator on this one, we have a great idea together. Bring your "A" game to this one GrabCAD'rs! :)

According to YouTube video, you have filters after pump. Do you need to install additional filter before the pump???
Grant Holohan about 11 years ago
What's the typical pressure in the housing?
bj about 11 years ago
3 questions:
1. is the flow continuous, I mean: is there always fuel going in and at the same time water and clean fuel flowing out at a certain rate?
2. How does the air in the system actually prevent the flow?
3. Is the air inside the filter (before seperation) or outside the filter but in the filter housing?
Govio about 11 years ago
@toomas, I want to know - Does air pillows form after broken emulsion process, that is, the air pillows are located outside filter but inside the housing ?
thanks
Toomas Kaevand about 11 years ago
In YouTube video there is indeed pump before filter and this is solution works fine. In the current situation we have to put filter before the pump and so far this has turned out to be a tough nut to crack.
Andrey about 11 years ago
@toomas, In requirements it is said that filter housing should be easy to service. How you service it?
thanks
Toomas Kaevand about 11 years ago
to bj. 1. The liquid flow is not continous all the time (this is like gas station pumps). 2. The problem is that we have to pull only the upper layers of the filtered liquid from filter housing (lower layers may contain water and this we want to avoid). If the air pillow is sufficiently large then it is virtually impossible to succ through this and system stops. 3. The air is not inside the filter, it tends to collect into the filter housing.
Toomas Kaevand about 11 years ago
to djgovio. The air pillow forms in the filter housing, outside the filter.
Govio about 11 years ago
to Toomas, i see. Why can't you put the pump before the filter when the solutions works (as uploaded in YouTube) ???
Drazen about 11 years ago
As Grant already asked: What is the pressure in housing?
Tyler about 11 years ago
Also curious on the housing pressure.
Will the filters be presented in an upright position as shown in the provided video, a horizontal manner, or at a tilt?
Thanks
Rob Podell about 11 years ago
I'm in, but the requirements are pretty confusing. Are you just asking for a housing for the filter? Or a complete system like in your video?
Mihaly Szilagyi about 11 years ago
So they want a houseing that solves the air-pillow problem WITHOUT stopping the system flow??? Or it can be stopped but it should be servisable easily??? more accurate requirements would be nice.
bj about 11 years ago
9 days ago I asked some questions, since then only more questions from other people were asked but no answers. Is Bioconsult still in business??
Simonr about 11 years ago
>Is Bioconsult still in business?v
Too busy brewing BioDiesel I'll bet!
Govio about 11 years ago
@ Bioconsult. I repeat !!!!! Why can't you put the pump before the filter when the solutions works (as uploaded in YouTube) ???
Simonr about 11 years ago
@djgovio - if they did that, there wouldn't be a competition!
Perhaps its because they want to use a different type of pump which needs pre-filtered oil? Who cares anyway - it's their competition!
Jean-Marc Bennett about 11 years ago
@kaspar - In the rules, it specifies sharing the model with the judges. Does that mean adding as contributors in the project? if so, I can't find Toomas.
nikitybe about 11 years ago
why i can't add toomas@bioconsult.eu to Collaborators
Mahender CH about 11 years ago
bad luck.... wanna participate but unfortunately only 1day left...
Branko Stokuca about 11 years ago
So not fair to all participants who did their "homework" in time.
Mahender CH about 11 years ago
@^ comeon..many were busy with 3d printer challenge since both the challenges had the same deadline dates.. Now all they had is 4 days to do the "homework", u did in a month..
Sara Sigel about 11 years ago
Please note, we have extended the deadline to March 10! Ask for private access now, if needed, and get your entries submitted.
Sara Sigel about 11 years ago
If you are having trouble adding Toomas to your project, please type out his full name: Toomas Kaevand.
saeid mirshahidi about 11 years ago
Thanks Sarah it's worked
Branko Stokuca about 11 years ago
@Mahender CH It didn't take me 1 month. It took less than a week. There were enough time for both challenges. In a real world deadline is a deadline. Nobody is forcing you to participate in all challenges, pick one if you can't handle both.
DWP about 11 years ago
This is a real world competition, they pay with real money and are expecting for something real and usable in exchange. Seems that you didn't offer them such a thing before the deadline, hence the delay.
Branko Stokuca about 11 years ago
And you must be his advocate. They can postpone the challenge for as long as they want that doesn't mean that they 'll get something better. Many people here asked them questions and they didn't answer so what do you expect? And by the way I am glad that you came along to save the day for Bioconsult.
DWP about 11 years ago
I don't think that the purpose of this challenge was to detect the best designer or the fastest athlete or the purpose of the comments to detect the bravest warrior.
BTW, I didn't intend to participate on this one, now I think I will.
Sara Sigel about 11 years ago
Let's focus on getting entries finished and submitted - only two days left!
Govio about 11 years ago
Hello Every One (Including GrabCAD staff). I would like to suggest something new for the projects which are held privately. All my suggestions will improve the transparency of the competition as well as improve the design knowledge among the participants. Following are my suggestion :
1) After the private project winners have been announced(i.e. not before the winners announcement), all there private winning entry design concepts should be revealed during the time of announcement, this will lead to a more transparent competition results and will also help the runners up of the competition to know tthe shortcomings of there concept design(i.e. what made there design not a winning entry)
2) The revelations of the winners design concept should include the pictures as well as notes on the uniqueness of there designs (i.e. what made there design a winning one among the competitors design.
Thanks ... Congratulations to all winners in advance !
Simonr about 11 years ago
One reason for keeping the entries private is that they might want to patent the idea. Under the Patent rules, the design must not have been published nor revealed to anyone not subject to a non disclosure agreement.
.An additional benefit of a private competition is the winners receive less hostility from other entrants who think their idea is better. I would not have believed how bad this could be until I'd experienced it first hand!
Govio about 11 years ago
$1,500 for a design to get patented is not worth the patenting job ! I agree about the winners hostility from other entrants but that hostility should be limited till the end of contest. At the end of privately held contest all the winning entries should be revealed to improve the transparency of the challenge between grabcad, sponsors and competitors. For example, If I am a sponsor-er of the competition, Luckily I get a patent-able entry, but this entry is not as good looking and appleling as the runners up entry, so I as a sponsorer can guide the patentable entry to get its design improved by referring to other entrants entries and thereby making the patentable entry more complete. Vice - a - versa. Who knows ? So as a entrants we deserve to completely know the winning entries whether it be private or public.
Simonr about 11 years ago
@djgoviv, the sponsor is 'buying' ideas as much as complete working solutions. I know from personal experience they garner ideas from many entries, whether they won the actual competition or not - and may patent some, winners or not.
I don't think entering a competition here any more than one on a Cereal Box gives any right to know the details of who won or why.
Having been on the receiving end of some of the hostility - I think on the whole, I would in future prefer not to know what design won! Roll on more Private Challenges!
Simonr about 11 years ago
Quoting from the rules: "Winners will be announced latest April 10, 2013v". Just wondering???
Sara Sigel about 11 years ago
Sorry for the delayed announcement. The top entries were so tough to choose! We will be announcing today. Thank you for being patient!
Sara Sigel about 11 years ago
