Design Process

Problem Background Research Requirements Solutions Development Work Prototype Test and Redesign

Design: Biomaterials

Variables Application: Structural, Therapeutic Location: Skeletal, Circulatory, Nervous

Systems Duration: Patient life, Minutes

Design: Biomaterials

Metals Ceramics Polymers Composites

Design: Mechanics

Complex Analysis – Simple Motion

Design: Mechanics

Inverse and Forward Dynamics Running Model

Prosthetics

Artificial device that replaces a missing or non-functioning limb External or Internal

Class Project

Design a “Prosthetic Hand” using: string, straws, rubber bands, cardboard,

washers, hot glue gun, and/or duct tape

Design Considerations

What is the Problem? Are you wanting to pick up a object? Grasp a ball?

Background Research What are the previous designs? Number of fingers? Number of finger joints?

Requirements Do you need to use all the materials?

Design Considerations

Solutions Development Work Prototype Test and Redesign
