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