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
