Open Sesame Challenge

Create the next generation Blackboard Door Reader

About This Challenge

Blackboard Inc. is looking to create new door access readers. These readers are positioned within proximity of a door. The readers read a campus issued credential and either allow or deny the user access based on the privileges issued to that user.

Blackboard’s Door Access system allows a campus to control doors as well as who has access to and when they have access to the door. The system allows administrators to set a door to always open, controlled, controlled with PIN, or locked. The doors status can change based upon the doors defined operating schedule. If a door is in a controlled state a user will use their campus issued credential at the door reader to gain access. The Blackboard system will verify the user has the privileges to gain access to the location at that specific time.

The new family of door access readers will replace the existing Blackboard Series Door Readers. Currently, there are four (4) Door Reader types: contactless only, contactless with a PIN Pad, contactless and mag strip, and contactless with mag strip and a PIN pad.

The new solution does not need to consist of all four different models if the requirements can be met with less than four models. Blackboard clients expect state of the art technology that conforms to and enhances a campus environment.

    Currently we have a PCB assembly that is 4.1" (104.14mm) tall X 1.3" (33.02mm) wide X 0.197" (5mm) thick. It is two PCB's stacked together (one antenna PCB and one the main PCB). The 4.1" (104.14 mm) dimension may be shortened by 0.5" (12.7mm) as we may move some of the circuitry from the main PCB to the antenna PCB. It is not necessary to model the PCB's, I would just make a "block in that size so you know it would fit inside the design you come up with.

    I wanted to let everyone know that we have added a clarification to the technical requirements as well. The door reader needs to be able to house the internal circuitry, approximately approximately 1.3” wide X 4.1” height X 0.2” deep (33mm X
    104mm X 5.3mm) in size. If your reader won't be able to house this circuity, I strongly recommend tweaking your design such that it does.

    Additionally, I want to remind everyone that the Mounting (see technical requirements above) is another important piece of your design. Please select one of the mounting options listed above and incorporate them into your design. And as always, if you have any questions, be sure to ask them here!

    Reda, a valid concern about the Lite up pin pad, but most of the use cases for these is in limited access areas only, generally faculty members or security guards. Most students will not need to use a PIN for access.
    Braille can be molded into the keys easily (not needed to be shown in your designs as we can add it if needed). If a standard phone layout the 5 key would have a bump on it and that will do. Other ways of adding braille are overlays or users will be issued a different type of card (higher security level) so they don't have to use the Pin Pad.

    We are not designing the "door lock", this device allows the user to open a locked door through other electronic controller (s) that send a signal to the doors lock mechanism to open or keep it locked. The device reads the users card, and based upon their credentials will allow the user to pass through or be denied entry.
    I see no contradiction as we never stated we are designing a lock, only a card reader to control access.

    Congrats to all of the finalists!

    @ BB, have to agree with @ Jonathon above that a number of the choices (not all) appear to be based purely on aesthetics rather than the criteria laid out in your design rules i.e. most tick the brief from your dot point of "Additional Design Considerations" and not much else. I can't fault you on the fact that they do look amazing but had I (and potentially a number of other entrants) realised that this was what you were after in the first instance I would have concentrated more in this area rather than the 'platform' itself.

    Don't understand this selection. Again... What were the criteria?
    Just look at that. Three! of final entries with slot for mag stripe card which is parallel to the wall. At this little distance to the wall this is very unfriendly. How user will be swiping? Please no offense but this part of mechanical design is basically wrong. Sorry but as for me it's unacceptable for the final enrty.

    Hi Alexander V., thank you for the feedback. The finalist selections were made based on how well the entry satisfied the Technical Requirements listed above, as well as the look, durability and ergonomics of the design. The card reader is definitely one factor that went into the decision, but there was a lot of criteria that the judges evaluated. When the winners are selected, more information will be released in regards to the ratings of each entry.

    Antonio DBG almost 10 years ago

    Congratulations to all finalists! It has been a truly enriching experience to have participated in this my first challenge and have learnt from all the great designers who have taken part in it. Regarding the models that have made it to the final, my favorites would be the models from Pedro Almeida and Anouar Barodi. Also, I think the model from Gorjup Design (Portuneso Door Access Reader) should be among the finalists.
    Respect the judging criteria I have to say that, in my honest opinion, it was a bit inconsistent. Some of the designs lack in the mechanical approach in terms of being vandal resistant, or how they would be assembled. In fact, some designs have a very fragile anchoring system, or don´t even have one! For me that was very disappointing, especially having in mind that one of the requisites was to “have creative and secure mounting options”.
    In general terms I agree with most of the models that were selected, although I believe that the visual (or concept) part had more weight in the decision that the mechanical part.
    That being said, again congratulations to all the finalist and wish you the best for the more-in-depth selection process. It has been a very nice experience, see you in the next challenge!

    Sorry I've been working hard the past few days so I have not had time to respond to the recent comments. Thanks to all the people who entered as well.
    That said, Jonathan and David....while I did not have final say in our picks, I did get to say if or not the designs presented were feasible. I do not look at ideas presented to me as impossible, I look at what can be done to make a design work. All of the picks can be made to work and metallic finishes or expensive components can be changed out to things that are less costly or easier to produce. Today's finishing techniques can reproduce just about any look you want for less cost than you may think, I can even tell you how to chrome plate any material without having to resort to harsh chemicals (look up Hyrochrome).
    Alexander, I agree that a card slot on the same plan as the wall is not ergonomic, but by taking a look at the design and imagining the slot at an angle you can envision how to make it work. As I said earlier, i do not look at what makes a design not work, but how I can change it to work.
    On the lack of wall mounting options, well to be honest not many entrants even gave it a second thought....so we really did not have many ideas to choose from. We also did not get many entrants who even bothered to explain their designs either.....something else we really wanted from the entrants.
    Choosing the top ten was hard, now deciding on the finishing places is even harder. we really appreciate all of the GrabCAD community for their work in this challenge and others we will have in the future.

    bottom line, your choices are your choices and you have every right to them, more power to you. Congrats to the nominees!

    "As I said earlier, i do not look at what makes a design not work, but how I can change it to work. "

    Would have helped to be more clear on this, this basically means that BB was looking for conceptual designs not finished polished RFM designs and files. The difference between a quicky conceptual model and a full-on design, ready for manufacturing can be weeks of work....

    "On the lack of wall mounting options, well to be honest not many entrants even gave it a second thought....so we really did not have many ideas to choose from..."

    I was one of the few who did put focus on the mounting system….sure, it might not have been BB’s taste in design but it did show an effort to meet the criteria and, in your words, it could be “changed to work” very easily, that compared to a model that didn’t offer any idea’s in terms of mounting system/vandal proofing should be given priority. 

    FYI, my first BB challenge, I had fun, glad for everyone, more power to the finalists, but I think next time I will second guess entering a challenge held by BB given That the criteria were not adhered to
