Contest Closed
Design a four-step set of stairs that can go flat at the to or bottom of the stairs, lift a person and wheelchair either up or down, and then take the normal stairs form. Stair lift must be able to operate from either the top or bottom of the stairs. See attached picture for desired end product.
Efficiency of elegance of the design.

#7 Automated Stairs by Rishi Gangwar
The stairs uses an rack and pinion mechanism to control all the stairs and is supported by sliders which can be altered according to the loading requirements on manufacturing.
it uses an stepper motor whose torque can also be alterd while installing to meet the loading condition.

The project is almost complete but please increase the price and specify the capacity to carry, it is vital in order to complete its last phase and for me to finally submit.

Hello Aly
How much is the height from the yard to the floor?

Please explain how to build a product with maybe patent protection? And...the development of the product will take not les than 2 months ant will cost just for the engineering not les than 10.000 Euro. So? Do not be so naiv please! However we speak about mashinery and transportation ot peaple, the requirements are not joke,

This product is only available in the UK. I'm trying to build this in my house for my son. It will not be a commercial product, just something that I can contract its design and build. My intention is to have three contests: 1) Engineering Drawing, 2) Engineering Design, including materials, electro-hydronic mechanizm and operations, and 3) Build.
This context is for the first step, the drawing only

Do u need electro-hydraulic operation?

I am prepare to work on this project.

This is not a DIY project. This is serious engineering with liabilities and patent infringement possibilities.
I agree with both comments before me which should explain why this is not a pre-pay as well.

How is this a contest? It looks to me like a reverse engineering job. Something that is already available. You might want to check if there is a patent on this product already.

An interesting project, but it is worth a lot more than $100!
