What is the Engineering Design
?
For example ,
• Design is a interaction between what we want to achieve and how we want to satisfy them.
• Design is a process of converting information that characterize the needs and requirements for a product into knowledge about the product.

Types of Design
Automotive and Tractors Engineering Dept .
4th Year Auto .
• There are different types of design:
• New Design: New tasks and problems are solved by new solution principles.
• Revised Design: The embodiment design is
customized/adapted to fit new requirements. The
employed solution principles are known and field-proven.
• Variant Design: Size and/or structure of parts and
assemblies are varied within the limits of the already planned system.
• Repeat Design: A new start of the production run with an unchanged design.
• Robust design: A systematic engineering based methodology (which is part of quality engineering
process) that develops and manufactures high reliability products at low cost with reduced delivery cycle.
Factors to be considered in machine design

• Some of these factors are as follows:
(a) What device or mechanism to be used?
(b) Materials
(c) Forces on the elements
(d) Size, shape and space requirements.
(e) The final weight of the product is also a major concern.
(f) The method of manufacturing the components and their assembly.
(g) How will it operate?
(h) Reliability and safety aspects
(i) Maintenance, cost of the designed product.
