Study Notes

Engineering Design Process (EDP) Overview

Engineering Design Process (EDP) is a systematic, iterative problem-solving methodology to create solutions that meet human needs and desires.

The Scientific Method

The Scientific Method is a linear method for investigation, involving experiments to test hypotheses.
Key Steps: Question, Hypothesis, Experiment, Data, Analyze, Report.

Engineering Design

Engineering Design Process is a systematic, iterative method for creating solutions to meet human needs and wants.
Steps in the cyclical process are shown via a diagram.

Steps of the Engineering Design Process

1. Defining a Problem: Clearly outlining the human need or want to be solved. This may require investigation if poorly defined. An example is a company facing financial losses that needs a designer to determine the cause.
2. Brainstorming: Generating ideas without limitations regarding the design. This can be done individually or in groups.
3. Generating Ideas: Designers let their imagination run free, building on suggestions from the brainstorming session.
4. Research Ideas and Explore Possibilities: Conducting research to determine if existing solutions or adaptations to existing solutions can solve the problem. Research may include mathematical and scientific information.
5. Identifying Criteria and Specifying Constraints: Establishing guidelines (criteria) and limitations (constraints) for the design.
6. Consider Alternative Solutions: Evaluating alternative methods to determine efficacy or simplicity/cost-efficiency.
7. Selecting an Approach: Choosing the solution after analyzing all possibilities that meets the established criteria and constraints. A documented selection process can be important in case the solution needs revisiting.
8. Developing a Written Design Proposal: Creating a written plan that details the design and required resources (sketches, drawings, models, instructions).
9. Making a Model or Prototype: Creating reduced-size versions, mathematical models, or 3D graphic models of the solution, without large investment; this makes testing possible. Prototypes perform exactly as the intended final solution. Mock-ups physically resemble the final solution visually but do not function as intended.
10. Testing and Evaluating: Testing models/prototypes to ensure effectiveness and efficacy against established criteria. Data collection from testing helps refine the design process.
11. Refining and Creating the Design: Improving the design based on testing and evaluation results. This might include improvement of function, appearance, market appeal or safety features. Target market should be determined. Designer and Engineers collaborate for an effective and timely production. Mass production follows this step.
12. Communicating Results: Sharing design process results (journals, design portfolios, drawings, sketches, or schematics) to foster innovation and allow others to learn from similar problems.
