  • 1. Engineering Design
    BMCD 2573
    MohdNazim Abdul Rahman
    Department of Design & Innovation
    Faculty of Mechanical Engineering
  • 2. What is Design?
    “to fashion after a plan” - Webster's dictionary
    to design is to create something that has never been
    although engineers are not the only people who design things
    To design is to pull together / synthesissomething new or to arrange existing things in a new way to satisfy a recognized need of society
  • 3. Design
    Good design requires both analysis and synthesis
    Understand how the part will perform in service
    Able to calculateexpected behavior before it exists in physical form by using the appropriate disciplines of science and engineering and the necessary computational tools – ANALYSIS
    Identification of the design elements that will comprise the product into workable system -SYNTHESIS
  • 4. Video Show!!!!!
  • 5. Engineering Design Process
    Starts with recognition of the need for the product.
    Both design and redesign require knowledge of the intended use of the product, plus information on the
    Technical data
    Materials and production
    For any product design you are part of a team!!!
  • 6. Engineering Design Process contn’
    Determine the need
    Starts with recognition of a need
    Sketching of the solution (product) is very useful during this step.
    Establish known information
    Includes gathering information on aspects of the products such as possible materials, market analysis, ability to manufacture, cost to manufacture, etc.
  • 7. Engineering Design Process contn’
    Stimulate Design Concepts
    Consider the various aspects in the manufacture of the product such as material, shape, etc.
    Investigate Design Concepts with Analytical Tools
    Use modern methods and tools to analyze design alternatives.
  • 8. Engineering Design Process contn’
    Gather all information and review
    Gather together all information and design alternatives and review so that decisions can be made.
    Test the design that appears best.
    Accept, Modify, or Reject
    Optimize the design by iteration
  • 9. Types of Design
    Original design - innovative design, It employs an original, innovative concept to achieve a need
    Adaptive design - adapts a known ' solution to satisfy a different need to produce a novel application
    Redesign - improve an existing design
  • 10. Types of Design
    Selection design - design task consists of selecting the components with the needed performance, quality, and cost from the catalogs of potential vendors
    Industrial design - improving the appeal of a product to the human senses, especially its visual appeal, more artistic than engineering
