M softer

by Yushuo Zhu

Project Description

Research indicates that long-term use of a mouse device causes pain and discomfort due to frictional contact with a desk surface. A product called a ‘wrist rest' can partially solve the problem by supporting the wrist, but this device is static and cannot move with the position of the hand. I used a design augmentation process to integrate a wrist rest with a mouse so that the mouse itself can perform the function of protecting your wrist and reduce the pain created by friction. This is where the idea of 'M softer' came from.

In order to get more accurate geometric data of the connection between the wrist rest and the mouse, I scanned my mouse with a 3D scanner and used the software tools of Meshmixer and Solidworks to construct the form. I then worked on the ergonomics and fit of the attachment by testing it with users which led to to more CAD iteration and the production of several prototypes via the 3D printing technologies of SLA and SLS.

The problem I needed to overcome was how to make the wrist rest and the mouse connection a temporary but sturdy situation? The solution was for two pieces of moulded silicone to be fixed to the inner surface of the wrist rest. Through further testing during the final phase of the design process the correct tolerance was achieved which enabled the rest and the mouse to be fixed securely and not able to separate in use.

Bio

I love to engage in development in the field of design. In fact, many products do not meet the emotional needs of the target group, so many existing products need to be systematically improved and innovated.
