Design engineering - OCRIterative design

Design engineering is the study of problem solving by ‘traditional’ engineering and design. It applies an understanding of materials, creative design thinking and manufacturing techniques.

Iterative design

The iterative process in design

Producing iterative models

typically work through an process, starting by producing early models or to test different aspects of their design.

The iterative design process

A prototype is an early sample, model, or release of a product built to test a concept or process or to act as something to be replicated or learned from. Early prototypes may be used to test the design’s appearance, functionality or for production or as .

A ‘breadboard’ can be used to make a proof of concept (POC) prototype to check if the circuit design will function as intended without using solder

Physical prototypes can be made in many materials including papers, boards and foams. Their purpose is to facilitate quick testing, analysis and improvement through iterative changes. James Dyson famously made 5,127 prototypes before he successfully made his concept ready for manufacture.
