Types of prototypes
Physical
Analytical
Using CAD software to calculate weakest point
Focus
Rough estimation of the product
Use for the initial stages of developement
Comprehensive
3D or more informative on the product
Planning of Prototypes
Step 1.
Define the prupose of the Prototype
Step 2.
Establish the level of approximation of the prototype
Step 3.
Outline an Experimental Plan
Step 4.
Create a schedule for Procurement, Construction and Test
Purpose of Prototype
Uses Of Prototype
Learning
Answering questioning about the design (a proof of concept)
The prototype focus on certain areas (known as Focus type)
New idea can be explored during prototyping stage to enhance product performance
Communication
Demonstration of product for feedback
Ensure customer's needs are understood correctly
Test Market demand
Plan production methods and cost
Integration
Combination of sub-system into system model (Beta version)
Assemble electronic devices to the parts
Almost a complete version (or known as Comprehensive Prototype)
Milestone
Goal for development team's schedule
Can be in different forms at different phase of development. it must be quick to make so that decisions can be made quickly
It will reduce design errors before planning for production
Prototype VS Actual Product
Not made form actual material. Made of soft material that is quickly shaped by hand
It may not have all the features in a product. Made to test or focus on certain aspect of the design
It may be shaped closed to actual product but no economical for mass production
