Design Framework
· specifications are the requirements for the final product.
i. performance: things it does.
ii. output: things it makes.
· constraints: the limits put on the design or materials.
2. Research and Investigate the Problem
· What are the needs?
· What other products/solutions are out there?
· What materials and techniques are available?
3. Generate Alternative Designs
· Brainstorming: a method for coming up with new raw ideas.
4. Choose and Justify the Optimal Solution
· List the strengths and weaknesses of the alternative designs.
5. Develop the Prototype
· Drawings and models are used to work out design problems.
· A scale model is a model made at a different size.
· A prototype is a full-scale or regular sized working model.
6. Test and Evaluate the Design Solution
· Develop one or more tests to assess the performance of the design.
i. Define your variables.
ii. Tests must match the design specifications
· Tests may suggest changes to make to the design.
7. Redesign the Solution
· Make any design changes suggested by the tests
· Re-Enter the Design Cycle at Any Step in the Cycle.
Aesthetics: the study of how things looks affect people
Controls: a device that adjusts the operation of a system
Ergonomics: the science of making things work better for people.
Ethics: having to do with right and wrong.
Feedback: information about the performance of a system that is used to adjust it.
Functionality: the ability o a product to perform its intended purpose/task.
Informed Design: a method of making choices and revising them as often as is necessary to arrive at the best definition of a problem and its solution
Innovation: an improvement on a device or productInvention: a new device or product
Maintainability: the ability of something to be repaired and maintained.
Optimization: the process of choosing the options that make a system work at its best.
Process: a series of steps.
Quality: the excellence of a product.
Requirements: the features that define the performance of a system.
Resources: any supply, service, or support.
System: a group of inter-related parts that work together.
Technological Literacy: an understanding of how technological processes work and how products are made.
Technologist: designs or maintains products, structures, and systems. They look for ways to make the human world easier to live in.
Technology: the creation of goods and services for human use.Trade-Offs: an exchange of one option for a better option.
