Throttle Pedal Design Challenge

Design a new gas pedal for a potentiometric sensor.

About this Challenge

The goal of this challenge is to design an innovative yet robust passenger automobile accelerator pedal assembly and interface for a new Microtechnologies potentiometric sensor. The system is intended for use in emerging market automotive applications. Automotive companies in China, India and South America could be using this gas pedal in the next generation of economy cars.

The winning design accelerator pedal will accomplish the following:

- Lightest weight design that utilizes accelerating manufacturing technologies and materials.

- Utilizes Microtechnologies core manufacturing technologies (injection molding, stamping, assembly, laser welding, tooling, machining, insert molding, automation) while incorporating new manufacturing technologies.

- Most efficient, cost effective, and simple method to have the Microtechnologies sensor to be assembled independently of the accelerator pedal assembly.

    sir. i downloaded the spec zip file to do this challenge. i placed it in a new folder just for the files. only two files show up. one "sldprt" and one "step" file. there are no .jpg files to open. I currently use 2014 Solidworks. I should be able to open the sldprt file. i get an error but believe it is due to the version maybe. I'm sorry to be a pain on this but i would like to compete in this challenge sir.

    What direction of rotation? CW or CCW? could you show this in your jpg file?
    How robust is this "rotary potentiometer" against the elements? It looks like the purple case rotates and seals on the fixed yellow ring. Do we need to incase it from road dirt and dust? Thanks

    The rotation direction can be either direction. The part is modeled in the center of the 40 degree range. These are easily configured depending on the specification of the designer. The sensor is both a fixed and rotating component. A sealed design housing would be the best solution to keep debris out of the sensor.

    It would be very helpful if I could get an better idea of the surroundings. how many space do you get ? and how is the connection to the environment of frame. because usually in a car everything is very crampy. so its difficult to make up a connection to a frame of part that maybe not even exists.

    Jake, Yes the connector will be a six pin sealed connector that is an automotive standard. We are still working to identify the specifics of this connector but the size in the model is the basic size. We are looking for new ideas for design of the pedal assembly that will be innovative and reduce weight and improve the experience for the end user. In the past pedals have been heavy and contained lots of plastic and metal so we are looking for innovative ideas to bring a new pedal assembly to market.

    Koen, the specification of spatial requirements and mounting is left to the freedom of the designer. We are looking for ideas on efficient mounting and ideas for possible integration into the cockpit. As features in vehicles increase space decreases in these environments so the most efficient use of space to securely mount the assembly in the vehicle is a key element of a successful design. We also understand that without specific constraints defined we will scale chosen designs to integrate into the final design.

    To use a phrase from Wikipedia: "This article reads like an advertisement.", or worse yet, a job ad. Don't get me wrong, I'm all for these competitions - I enter many of them. What I don't want to see happen is more companies just "shopping out" some of their design work to a low cost center like this platform. I mean, the first prize covers about three days (24 hours) of wages (give or take), and the company gets 50+ entries to choose from. If I were designing something that was actually used in manufacture (which I do currently), I think I'd like to be more committed to the company, like having stock options (and I do).

    This is an interesting challenge. However, before commencing the design the following would be useful to achieve a more real world design. 1. Pedal Stroke/Force required to avoid unintended acceleration or driver induced oscillations. 2 Pedal hinge location - top hung or floor mounted. 3. Temperature is quoted at 180 degrees CELCIUS. Fahrenheit is more achievable. The driver is boiling!! 4. Sensor height relative to floor - to avoid sensor failure in vehicle wading tests. Thanks Graham

    Paul, not sure I understand your Wiki reference but we are all about accelerating good hardware for everyone as our company MTP. This means breaking away from our traditional linear way of product development in the past and finding ways of accelerating the process. If we were just looking for cheap labor we would have just found an agency in a low cost region and "shop out" as you say. This is really about accelerating the process by opening ourselves up to a public community of designers. Bringing this level of transparency opens us up in a lot of areas since all of our competitors can see what we are doing. This challenge is only one element that goes into developing a new product and our engineering team is responsible for delivering a full solution so there is a lot happening in the background past what you see here. This process is new for us so as we gain a comfort level we will increase the prize purses. I can say that for 2016 we have planned more than 10 challenges with a total price purse of over $100,000 so this will be a significant commitment for us. I hope those that catch the vision for this type of accelerating technologies are excited for this shift and those that are still skeptical I would recommend two books, Abundance and Exponential Organizations to better understand these future trends. Thanks!

    Graham, Thanks for your questions as it appears you are well versed in automotive design standards. For this project we are looking for new innovations in pedal design and novel ways of lightweighting that will serve as the base to then apply the standards required by the automotive standards for a pedal design. We also have not identified specifics as this is a global product and standards differ for different countries. We also are not stipulating the location of the sensor or a pivot point as location may be independent based on a well sealed design. The temperature requirements are a product of the testing of the product that is already known. Yes it is excessive however this is relative to the production processing in manufacturing. I hope that clarifies your points and look forward to your ideas.

    Just throwing this out there....

    I've been doing these competitions for the past 3 years. You can't really compare them to a salaried job if you were employed as an industrial designer, they're just two different things altogether. In my case, I used competitions like this as a way to 1. practice my CAD skills 2. Build my portfolio 3. Gain exposure. All of which have been achieved. So now I'm in the position where I have been offered paid employment at companies, or I have picked up contracts from the connections I made here on GC. None of it would have been achievable without all of the above.

    And actually 100,000$ is a huge amount so I commend that. Yes, I do believe there are some companies that take advantage of the croudsourcing for cheap idea's and labour but often, you get what you pay for :). Also, Like Jason mentioned, it can be a risk for the company and the designers in terms of IP. The company is exposing their secret sauce and the designer is offering their secret sauce. A friend and I bowed out of one competition recently for this very fact. We were going to enter our idea but after some thought, we decided to pursue it on our own :)

    Unfortunately, do to some hetic times, a few job offers etc. probably won't have time to submit something for this one but who knows...

    good luck to all!

    1. So if I understand correctly, the purple part is the rotating part, max 40 degrees rotation? The yellow part will be fixed to the frame? There isn't much lip on the yellow part, or bolt holes, how is it supposed to be fastened?

    2. Any preferences on materials, 3D printing, Steel, aluminum, CNC, bent plating etc. is it anything goes or can you give us a preference. Otherwise it leaves things pretty wide open. Are the vehicles economy class? or more high end?

    Jonathan, Thanks for your comments. As for your questions you are correct on the angle of rotation and the yellow would be the fixed component. We prefer laser welding so that we can both seal and fix this component into the housing but we are open to any high volume production that is both effective and efficient in a production environment.

    MicroTechnologies over 8 years ago

    Jonathan, The purple component does rotate either CW or CCW based on desired intent of each design. There is a positive stop tab built into the fixed part to stop the rotation of the contact. This would not be robust enough to stop a pedal with the given force so we advise each designer include this into the pedal actuation. Thanks!

    You mention "40 degrees rotation of sensor with positive stops", what does positive stops mean? Am I reading to much into this? Is it a normal accelerator pedal or does it have to stop in intervals while it moves?

    Does the entire purple unit rotate as one? Is there any kind of securing method on the "double-D", like a set screw or clamp? What material is it? Could it accept an interference-fit of a metallic piece? Is there any resistance while rotating the pot (it looks like it may be some kind of sinusoidal sensor, in which case, no)? Is the yellow piece clamped by any other method, ex. is the design open to add mounting tabs? I guess the main question is: Is the Smartpot in it's finished design stage, or are we (GC users) to find better ways of possibly mounting it?

    Hi KHANTECH, Hein and all other winners, my apologies for the slow communication there. You should receive an email today and prizes should be distributed next week.
