Design process
- 1. Identify the problem When given a problem to solve, I find it essential to identify the root of the problem, and to decided whether it can be solved by engineering design. Focusing on the root of the problem simplifies the solution brainstorming process and increases accuracy.
- 2. Brainstorm possible solutions Use creative thinking techniques to brainstorm possible solutions to the problem. At this early stage, I prefer not to focus too much on the technical details of the solutions.
- 3. Evaluate and reframe problem if needed Evaluate the possible solutions and decide whether there is scope for developing an engineering solution to the problem. Reframe the problem requirements if needed.
- 4. Conceptual Design Brainstorming Sketch / model designs based on the initial brainstorming stage solutions as well as on newly thought of solutions. Develop detailed designs by deciding what the main features of the product will be. Functionality, cost, durability, and other DFXs must be taken into account when developing these designs. Low-fidelity prototypes should be made. May need to reframe problem requirements after evaluating the designs.
- 5. Select best solution Use decision-making process and cost-benefit analysis to decide which of the designs is the best solution to implement by evaluating how well it meets the design criteria.
- 6. Build and test prototype Build a high level prototype of the chosen design. Test the prototype, and ensure that it meets all requirements. Identify evident problems or sources for future problems, and try to eliminate them by modifying or prototype. May need to reframe problem requirements again after evaluating the prototype, though this should only be done after working with different versions of the prototype.
- 7. Evaluate and refine prototype into finished product Evaluate the prototype, and after reaching the stage where the prototype is error-free and ready to be converted into a finished product, finalize the other aspects of the design.
