Classification of Machine Design

Classification of Machine Design	Description
1. Adaptive design	Involves minor alterations or modifications to existing designs of a product. Requires ordinary technical training.
2. Development design	Requires scientific training and design ability to modify existing designs into new ideas, often involving new materials or manufacturing methods.
3. New design	Requires extensive research, technical ability, and creative thinking. Involves creating entirely new designs from scratch.
Design Methods:
a) Rational design	Relies on mathematical formulas based on principles of mechanics.
b) Empirical design	Relies on empirical formulas based on practical experience and past knowledge.
c) Industrial design	Considers production aspects for manufacturing machine components in an industry.
d) Optimum design	Focuses on achieving the best design under specific constraints by minimizing undesirable effects.
e) System design	Addresses the design of complex mechanical systems, such as a motor car.
f) Element design	Deals with the design of individual mechanical elements within a system (e.g., piston, crankshaft, etc.).
g) Computer aided design	Utilizes computer systems to assist in creating, modifying, analyzing, and optimizing designs.
