Introduction to Engineering Design
Definition and Concept of Mech. Design
Design is essentially a decision-making process
For every problem, we need to design a solution
Design is to formulate a plan to satisfy a particular need and to create something with a physical reality
Basic concept of design
Decision-making : every stage of design
Consideration of different factors
To draw certain conclusions leading to an optimum design
Engineering Design is the result of a process
Involve Prototyping, testing, modeling and analysis
Mechanical Engineering Design
knowledge of statics, dynamics, thermodynamics
Good Design
requires both analysis and synthesis
provides a solution to the identified need or problem in an innovative manner and defines a standard for others to follow
Design Process
Phases of Engineering Design
Conceptual Design
Embodiment Design
Detail Design
Planning for Manufacture
Planning for Distribution
Planning for Use
Planning for Retirement
Codes and Standard
Codes
Tell engineer what to do and when and under what circumstances to do
Types of Codes
Performance Codes
Stated in terms of the specific requirement that is expected to be achieved.
Prescriptive or specification codes
State the requirements in terms of specific details
Standard
• Tell engineer how to do it and are usually regarded as recommendations that do not have the force of law.
Categories of Design Standard
Performance Standards
Published standards such as seat belts
Test Methods
Methods to measure properties
Codes of
Practice
Give detail design methods for repetitive technical problems
