Engineering design

  1. 1. Engineering Design
  2. 2. Engineering DesignThe process of devising a system, component,or process to meet desired needs.It is a decision-making process, in which thebasic science and mathematics andengineering sciences are applied to convertresources optimally to meet a statedobjective.
  3. 3. INPUT Engineering Design Cycle Research Modeling OUTPUT Communicating Measuring Implementing Modeling Measuring CommunicatingResearch Modeling ImplementingLearning about a Using mathematics Going from ideas, Determining how well a Expressing the results ofproblem before to understand and models or concept to a system or device your engineering work so functions by performing others can understand,solving it and make predictions physical realization of measurements. reproduce and improve it.finding information about the system the design.about it. performance through any valid solution method.
  4. 4. 4 Levels of Designs Designing Creating something NEW under constraints to achieve a near optimal outcome. Analyzing Being able to extract meaning from collection of information. Applying Using information to accomplish something concrete.UnderstandingBeing able to recallwhat you learn anddefine, explain orgive examples toothers.
  5. 5. Tools in Used in Engineering Design• Functional Decomposition or Block Diagram• Gantt Chart• Project Manager
  6. 6. Functional Decomposition or Block Diagram Breaking the system down into its functional part to understand how this parts operate with respect to the whole.
  7. 7. Gantt ChartType of bar chart that illustrates project schedule.
  8. 8. Project ManagerA person that balances the cost, schedule andperformance.
  9. 9. Project Definition and Specification
  10. 10. Defining a Project1. Is the problem important?2. Is the problem solvable?
  11. 11. Specifications• Outline as precisely as possible at a given stage of the project what you are supposed to do.• It characterizes what you produced and how to use it.• Specifications are a form of contract.
  12. 12. A Good Specification• State exactly what you are going to do, not how you are going to do it.• You need to develop a clear mental image of what you are designing.
  13. 13. Pointers in Design Specification• Constraints External factors that will limit your exploration space.• Standards Standards allow us to communicate complex constraints in a minimal number of words. Standards make sure our work is compatible with others.
