Solution
A stand-alone nail trimmer has been developed whereby the client is able to perform nail cutting by himself/herself.
This ergonomically designed device allows user's hands to be stabilized comfortably. The design idea generation came from the concept of a baby nail trimmer as well as a disc polishing machine. The final solution is a stand-alone nail trimmer whereby there is a disc which is connected to a motor, there will be sandpaper/ grinding paper attached to the disc and the rotational motion will trim away the finger nail when it touches. To enhance the safety, an enclosure has been built around the finger slot/hole so the client will be able to insert their fingers into the enclosure. The distance from the enclosure to the finger slots are fixed. This will allow the client to perform nail cutting manually without any assistance and to cut all the fingernails simultaneously.
