I have a design of a cushion with mechanical elements (the inflating and deflating process is directed by a preprogrammed mechanical mechanism, not by hand). I don’t know if my design is the best possible design so I expect from you that you make suggestions of technical improvement - as is necessary in manufacturing design. The project includes an aircompressor, an aircushion and mechanical devices/valves to deflate and inflate the cushion. Aircompressor and vavlves surely already exist, you don't need to design that.

For this task you must be an engineer (no draftsman please). I don’t put a deadline on this project but I expect at least one person to work fulltime for it, and not do multiple projects.

Because the project has a lot to do with inflatable cushions I will contact producers of such devices in order to help you. While the mechanical elements of this invention are simple, we need to find out how much air tubes can deform if a given weight is applied to them.

You might also be needed to build ap rototype. For the scope of this project it is enough if you emulate the form of the cushion by using matress foam, that is you do not need to build the mechanics. The issue of the prototyp is just form/ergonomy.

You will also be needed to source premanufactured parts (aircompressor, valves, airhose etc) or give at least an exact technical specification so that someone doing sourcing can easily find them.

This project is a re-awarded project, that means the last freelancer failed on the task. I will now explain what went wronng in the last co-operation:

The company I awarded the project thinks that when I tag a project as “engineering , mechanical engineering and manufacturing design“ what I am truly looking for is a draftsman. What is worse, I put a row of technical questions right at the beginning of the project. The company just avoided answering them, instead of admitting that they are not qualified to answer them. I have waited a month for answers to the most simple questions. I can not afford to loose more time this way so I have the following suggestion for the reawarded project:

!!!You will be allowed to withdraw from the job in the first 3 days if you find it to difficult!!!

I also expect all information I give you to be threated confidentially. You will need to sign an NDA before I give you information about the exact design.
