Engineering design
- 2. Engineering Design The process of devising a system, component, or process to meet desired needs. It is a decision-making process, in which the basic science and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective.
- 3. INPUT Engineering Design Cycle Research Modeling OUTPUT Communicating Measuring Implementing Modeling Measuring Communicating Research Modeling Implementing Learning about a Using mathematics Going from ideas, Determining how well a Expressing the results of problem 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 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. Understanding Being able to recall what you learn and define, explain or give examples to others.
- 5. Tools in Used in Engineering Design • Functional Decomposition or Block Diagram • Gantt Chart • Project Manager
- 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. Gantt Chart Type of bar chart that illustrates project schedule.
- 8. Project Manager A person that balances the cost, schedule and performance.
- 9. Project Definition and Specification
- 10. Defining a Project 1. Is the problem important? 2. Is the problem solvable?
- 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. 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. 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.
