Early Design Brainstorming
09/04/2017 at 03:27 • 0 commentsOnce we came up with a set of goals and requirements for our prosthetic hand the next logical step was to determine what we wanted the the hand to be capable of actually doing. Ideally the hand should be extremely easy to use and should be capable of gripping a range of different objects without being too difficult or confusing to the user. The following picture illustrates the brainstorming that went into the design throughout the process of determining where the degrees of freedom would be in comparison to an actual human hand. The image also shows the general systems that we will likely have to take into consideration in the design of our prosthetic.

Project Requirements and Goals
09/04/2017 at 02:56 • 0 commentsBefore going straight into the design process with whatever ideas came to mind a decision was made to come up with a set or requirements and goals for our prosthetic hand. We came up with a total of 5 primary goals which we will continue to look at throughout the design process such that we stay aligned with our true objectives.
Prosthetic design Goals
- The prosthesis should serve the user; the user should not be the servant of the prosthesis.
- User friendly or simple to learn to use. Any device should be intuitive and natural. An amputee should be able to learn to use the prosthesis quickly and easily.
- Independence in multifunctional control. Control of any function or degree of freedom, should be able to be executed without interfering with the other control functions of a multifunctional prosthesis.
- No sacrifice of human functional ability. The prosthesis should be used to supplement, not subtract, from available function. The control system should not encumber any natural movement that an amputee can apply to useful proposes.
- Natural appearance. Movements that appear mechanical in nature attract unwanted attention in social situations and may not be pleasing to the eye.
