tiny challenge : tablet hinge

By Matthieu Lemaître on 20 Apr 13:40 0 answers 0 comments

Hi, so this is kind of a challenge but without time limit and without prizes. (at least for now)

What has to be designed, is the hinge of this tablet : Wacom Quanva LLCM drawing tablet case (hinges shown on the pic below)
__________________________________________________________________

IT WILL BE COMPOSED OF AT LEAST 3 SEPARATED PARTS :
-One that will be soldered on the foot or the screen of the tablet, which we would call the foot.
-One that will be fixed to the arm connecting the 2 hinges, which we would call the arm.
-And the button that have to make the hinge free when pressed, and fixed when released.

Foot part will need a free circular face at it's end to be soldered on the tablet foot.
The arm can be attached to the tablet arm the way you want, it just have to follow the rotation from the foot part and don't follow the button push.
The button can be fixed in rotation with either of those 2 parts or any.
___________________________________________________________________

THE DIFFERENT SOLUTIONS WILL BE RANKED FOLLOWING THE SPECIFICATIONS AND WEIGHTED CRITERIAS.
(The specifications are here : http://goo.gl/7tsi9l)

INFORMATIONS ABOUT THE SPECIFICATIONS :
If any value is exceeded, the solution is inadmissible.
The color show how hard each criteria is.
Criterais with no weight, mean that you just don't have to exceed their values, being way better than them won't rank the solution higher.
Here the is only 3 criterias with weight, that mean, a solution that is just 2x stronger ("just" because the 2 other weighted criterias are to their acceptance limit) will be the same rank as a solution that is just 4x cheaper.
So if you acheive to have an infinit number of positions, you would think that you get infinit point and will necessarly win :p
but no, each criterias are limited to 4x better than the limit, so maximum rank is 27.

___________________________________________________________________

The "question" software is solidworks, but you can make your solution on any software as long as you can prove that all criterias are fullfilled.

If you need any more details ask me, i might have forgotten some things.

I will also make myself one or more solution(s) for this challenge, but i wanted to see what other peoples could find, and try to make an easy to understand challenge.

Well, good luck :)
