Conceptual Design
Codes and Standard
Standart
Collections of laws and rules that assist a government agency in meeting its obligations to protect the general welfare by preventing damage to property or injury or lost of life to persons
Categories of design standart
Perfomance standart
Published standards such as seat belts, crash safety. auto
Test Method
Test Methods Methods to measure properties such as strength, conductivity electrical resistivity.
Codes of Practice
Codes of Practice Give detail design methods for repetitive technical problems such as design of piping, heat exchanger, pressure vessels.
How its made?
Prepared by individual companies for their own used
Prepared by government agency set a standard.
Prepared by group of companies in the same industry
Reducing Cost of design
Use of design standards saves designer from spending time on finding solutions to recurring identical problems.
Provide a firm basis in negotiation and understanding between buyer and seller.
Failure to incorporate design standards may lead to difficulties with product liability.
Code
Generally agreed upon set of procedures, criteria, dimensions, materials or parts such as dimensions and sizes of screws, bearings and procedure for testing yield strength.
Types of code
Perfomance code
Stated in terms of the specific that is expected to be achieved. The method requirement to be achieved is not specified.
Prescriptive or specification codes
State the requirements in terms of specific details and leave no discretion the to designer.
Ensuring
Efficiency
Safety
Promotes
Interchangebility
Compatibility
Definition and Concept of Mechanical Design
Basic concept of design
Decision-making - Every stage of design
Consideration of different factor
Engineering Design- The result of the process
Identification need or problem
Mechanical Engineering Design
Use the knowledge of static, dynamic, and thermodynamic in design process
What is Good Design
Requires both analysis and synthesis
Analysis= Use engineering and sciencetific to characterize product perfomance
Synthesis= Involves the communication of solutioninto a total workable system
Provides a solution to the identified need in an innovative manner and defines a manner standart for each other to follow
Product of planning and work
What is Design
Design is essentially a decision-making process
Design is to formulate a plan to satisfy a particular need to and to create a something with a physical reality
Leads to Innovations
Technological advances
Changing costumers need
shortening product life cycle
