Product Development and Prototyping
Product Development Process
Designing, creating or updating, marketing and providing product to targeted audience
Survey customer needs
Define target specifications
Ideation/brainstorming stage
Selecting concept
Detailed drawing
Prototyping
Evaluation/testing
Repeat step 6 again if there is major problem after evaluation
Mass produce/manufacture
Marketing
Develop product design digitally
Exchange CAD data format
Commonly used file exchange format are
STL
(STereoLithography),
IGES
(Initial Graphics Exchange Specification),
STEP
(International standard for product data exchange),
AMF
(Additive Manufacturing File)
Purpose of Prototype
Four uses
Learning
Communication
Integration
Milestones at various stages of development
Difference from actual product
Not made from actual material
Doesn't have all the features of the actual product
Shaped close to actual product, but may not be economical for mass production
Types of prototypes
Physical
Comprehensive (An actual physical product close to the actual product, to learn more about the product)
Analytical (Design with computer calculation such as stress on parts and thermal distribution)
Focus (A prototype just to test out specific feature or focus only on certain features)
Planning Prototyping
Define the purpose
Establish the level of approximation of the prototype
How close the prototype be to the final product
Physical or analytical
Outline an Experimental Plan
Protoyping is experimenting
Collect enough data
Plan the experiment
Create a schedule for Procurement, Construction and Test
Treat prototyping as a sub-project
Apply project management skill
