2. The Design Process • Used to move from problem to concept to solution. • 10 steps to reaching the best possible solution with the least amount of effort in the shortest amount of time. • Identify the Problem • Identify Criteria and Constraints • Ideate • Develop Ideas • Evaluate Possibilities • Select an Approach • Build a Model and Prototype • Test and Refine • Document and Present • Manufacture • Invest more effort in the early stages of the process to maximize efficiency.

3. Step One: Identify the Problem • Write a statement that answers the following questions. • What are you trying to design? • What problem is the design attempting to solve? • Who are the stakeholders? • Example: How can I design a __________ that will __________ for __________ ?

4. Step Two: Identify Criteria and Constraints • Thoroughly research the problem. • Collect important data that will determine design criteria and constraints to lead to a possible solution. • Write a statement that specifies the design requirements. (Information might be of more use in tabular form.) • Deliverables must include answers to these two questions: • What are the design limitations? (size, weight, environment, materials, etc.) • What are the criterion that indicates a successful solution to the problem?

5. Step Three: IDEATE (brainstorm) • Conduct a group discussion using information from the previous steps. • Produce many possible solutions to the problem. • Ensure that everyone is free to contribute and all suggestions are recorded. • Sketches are crude and quick. • No proposal is discounted or championed. • Deliverables should include at least three of the following: • Analogy • Mind Map • Flow-Chart • Sketches • Design Notes

6. Step Four: Develop Ideas • Select two or three of the most promising ideas from Brainstorming and develop them more thoroughly. • Working with pencil and rule, create new drawings that show greater detail in top, front, and side views (orthographic) as well as a dimensioned isometric view. • Drawings should be neat showing parts in closer proportion than the sketches. • Drawing components should be clearly labeled to include notes. • Deliverables must include: • Orthographic Drawing • Isometric Drawing • Dimensions • Labels • Design Notes

7. Step Five: Evaluate Possibilities • Developed ideas shared and discussed among team members using the criteria and constraints from Step 2. • Pros and Cons should be listed for each design idea and notes made on the drawings accordingly. • Deliverables Should Include: • Table of Pros and Cons for Each Developed Idea • Design Notes Added To Drawings

8. Step Six: Select an Approach • Working as a team, come to consensus regarding the best solution to the problem. • Consensus is a process for group decision-making. It is a method by which an entire group of people can come to an agreement. The input and ideas ofallparticipants are gathered and synthesized to arrive at a final decision acceptable to all. Through consensus, we are not only working to achieve better solutions, but also to promote the growth of community and trust. • Deliverables Must Include: • Prioritized table of each solution’s characteristics • Statement specifying why the selected approach is the best solution to the problem • Written clarification how the solution meets the criteria and adheres to the constraints regarding the identified problem.

9. Step Seven: Build a Model and Prototype • Models can be • Virtual objects designed using CAD. • Built using materials like cardboard, wood or Styrofoam. • Kits with snap-together or bolt-together parts that can be used to fabricate models of solutions to a problem. • To scale or full-size. • Prototypes are typically working models. • This phase is used to determine problems with spatial relationships or component interaction. • Deliverables Must Include: • Virtual Model • Prototype (Scale or Full-Size)

10. Step Eight: Test and Refine • Examine and evaluate the prototype insuring its performance meets the criteria and constraints. • Identify problems with the prototype’s design. • Brainstorm possible solutions while implementing changes until the prototype solves the problem reliably. • Deliverables: • Fully Functional and Reliable Prototype

11. Step Nine: Documentation and Presentation • Complete all the documentation necessary to construct the solution to the problem. • Present this documentation to the stakeholders for review and approval. • Deliverables should include the following: • Project Presentation • Gant Chart • Dimensioned CAD / CAM Design • Component Specifications • Detailed Design Notes • Component Specifications • Manufacturing / Assembly Instructions

12. Step Ten: Production • Manufacture a full-scale fully functional solution to the design problem. • Test and refine the product until it operates reliably. • Deliverables to include: • Fully Functional and Reliable Solution • Updated and Complete Documentation
