Understanding Design in Engineering

Understanding Design in Engineering

1. It means translating customer requirements

   • "Everyone has a different view of what the customer needs"
   • Customer requirements should be translated into measurable design objectives for the identified critical parameters

2. Any change of specification causes a addressing of all decisions that depend on that specification

   • is estimated that fully 35% of all product development delays are directly caused by such changes

3. The progress of the design is given by

   • New technologies and competitiveness
   • As the process progresses, the product advances

4. It is to focus on what is going to be designed and then on the aesthetics of this

5. Careful development of requirements is key in an effective design process

   • From this design process come specifications that understand the problem
     • Techniques to generate specifications
       • (QFD) Deployment of quality functions
         • Improves the quality of the product
         • 69% of companies use it
         • Increases the customer satisfaction
         • Facilitates rational decisions
         • Can be applied to problems or subproblems

6. The QFD method is used to generate information in engineering

   • In this is built the house of quality, with numbered rooms that detail the steps to follow
     • 1. Who
     • 2. What
     • 3. Who vs What
     • 4. Now vs what
     • 5. How
     • 6. What vs how
     • 7. How much
     • 8. How vs how

7. For each product there is a customer

   • Can be
     • Internal
     • External
     • For an organization
   • And what does every customer want?
     • Useful life of the product
     • Ease of production
     • Visually appealing

8. What should be designed?

   • Customer information is collected with:
     • Surveys
       • Open or closed questions
       • Should be
         • Specify the necessary information
         • determine the questions well
           • Do not guide the customer to the answer they want
           • Don’t tangle two questions together.
           • Use complete sentences
     • Observations
     • Group approaches
     • With the model of
       • Abetter
         • Implementing the 1 to 10 stage
       • Kano

9. Assess and identify competence

   • Studying existing products
     • Create ideas of what already exists
     • Reveals opportunities to improve existing products
       • Companies do it and it’s called competitive benchmarking

10. Generate engineering specifications

    • They consist of parameters of interest and objectives for parameters
    • Specifications are the translation of the client’s voice to the engineer’s voice
      • Serve to give a vision of the ideal product
      • Serve as criteria for design decisions
    • As the life cycle of the product
    • Each specification must measure at least one customer’s requirement
    • Each specification must be measurable
    • Identify from the beginning the dependencies of each specification

11. Standards in design engineering

    • EE.UU standards covered
      • ANSI
      • ASTM
      • UL

12. Objectives

    • How important is it to meet them?
    • Establish from the outset
      • Modify them as the project progresses

13. The result of understanding the design problem

    • Understanding the design requirements
    • Communication tools are created
    • Creates a working document that is used and updated as needed
      • This ensures that the problem is well understood
