Warm Up #7 Think about a simple object, like a can opener, eyeglasses, a pen, scissors, a spoon, etc. What is something you wish the object would do or would do better?

Technology and the Design Process Lesson 3: The Design Process

Essential Questions What is the design process? How can different solutions be tested and compared?

Creativity and Design Factors Creativity – the ability to make new things or to think of new ideas Plays a large role in designing products Engineering, appearance, cost, and efficiency are other factors Efficiency – the ability to achieve a desired result with as little effort and waste as possible Why is creativity an important design factor? How can creativity affect the design of a product?

Creativity and Design Factors Creativity leads to original and imaginative ideas that can help solve a problem or meet a need, while others can’t Engineering turns an idea into a product that works well, is durable, reliable, and easy to maintain Appearance is important to the purchaser Everyone has slightly different ideas about why is attractive, which is why products often come in different designs

Designing Products Why can old ideas be improved?

Designing Products Why can old ideas be improved? Old ideas can be improved because advancements have been made in science and technology Design process – a series of steps used to find solutions to specific problems

Improving on Old Ideas ACTIVITY Discuss how this product was used How did this product benefit society at the time? What are some problems in this design? What are some things that were done to improve on this product?

Designing Products Identifying a problem or a need Clearly define the problem, which must be specific enough that a solution is possible Problem statement – a statement that clearly defines a problem to be solved Poorly worded statements result in wasted time and effort Criteria and constraints Criteria – the standards by which the product will be evaluated Constraints – limitations put on the design of the product from outside factors, such as cost, efficiency, environmental impact, or availability of materials

Designing Products Research information and develop solutions Researching solutions that have been tried, failed, and worked is a great starting point as it could save you time and get you a better solution Brainstorming – a problem-solving technique that involves individuals contributing ideas without the fear of being criticized Pugh charts Used when people need to pick between multiple objects Pugh chart – a method used to compare options or solutions

Warm Up #8 Why is a prototype important?

Pugh Chart Activity Compare and Contrast the 2 items with each other. Put your criteria into a pugh chart What was some of your criteria?

Designing Products Construct a prototype Prototype – a full-scale model that is used to test a new product The prototype is tested and changes are made based on tests Testing and evaluating solutions The design is tested and reviewed throughout process Allows engineer to find and correct problems Redesigning your solution Does the product work the way it should? Does it meet the criteria and constraints?

Designing Products Communicate results Full-scale production Results must be communicated no matter what Reports are made, presentations are had Full-scale production Once all problems are resolved, the new product is manufactured During this process careful evaluation and testing occur with everything

The Design Process Why is it important to test a solution? What happens in the design process if a new solution is proposed? Why is communicating results an essential part of the design process? Why is it important to continue the evaluation process after full-scale production begins? http://pbskids.org/designsquad/video/boats-recycled-materials/

Review Copy and fill in the graphic organizer to list the steps in the design process. Solve the problem of a river flooding annually by putting the following steps in order: Investigating the river’s source and its geography Build a model dam Create several designs of dames Write a problem statement Test the model Select the most promising dam design Redesign the model
