August 28, 2008 I1-4 With 1 partner: IOT POLY ENGINEERING I1-4 August 28, 2008 With 1 partner: Get out last night’s homework and critique the paper layout for correct formatting. Go through your assignments and critique them: What was done well? What needs improvement? Take notes on what you can do to improve at the bottom of the homework assignment (notes must be legible, but not lettered).

Design Process I1-4 Design Principles Note: IOT POLY ENGINEERING I1-4 Design Process Design Principles Design is the result of a formal, sequential process. Design is mostly driven by profit motive and market. Design is the result of goal-oriented research. Designs must be continually checked, refined, and improved. Note: Design problems seldom arise in a clearly defined form. Design requirements sometimes compete with each other.

Design Process I1-4 Clearly Defined Steps: Clearly Defined Steps: IOT POLY ENGINEERING I1-4 Design Process Clearly Defined Steps: Define the problem Identify criteria and specify constraints Brainstorm Research and generate ideas Explore possibilities Select an approach Develop a design proposal Make a model and/or prototype Test and evaluate the design Refine the design Create the final product Communicate processes and results Clearly Defined Steps: Working with a partner, put the steps in order. Make a model or prototype Explore possibilities Identify criteria and specify constraints Brainstorm Refine the design Research and generate ideas Communicate processes and results Select an approach Define the problem Develop a design proposal Create the final product Test and evaluate the design 1 2 3 4 5 6 7 8 9 10 11 12 8 5 2 3 10 4 12 6 1 7 11 9

IOT POLY ENGINEERING I1-4 Design Process Design Process as you should know it: Define the Problem Brainstorm, Research, Generate Ideas Explore Possibilities Develop a Design Proposal Make Model/Prototype Test and Evaluate Refine the Design Communicate the Solution Next: an outline of these steps of the Design Process – use this all year

Outcome: Sentences, Paragraphs, Lists IOT POLY ENGINEERING I1-4 Define the Problem 1 Describe the situation (that needs a tech. solution) What must your solution accomplish? What is the need or desire? Establish the criteria and constraints under which the solution must operate What are solution requirements (criteria)? What are the limitations on the solution (constraints)? Outcome: Sentences, Paragraphs, Lists

Brainstorm, Research, Generate Ideas IOT POLY ENGINEERING I1-4 Brainstorm, Research, Generate Ideas 2 Gather information – Obtain background information needed to begin developing solutions to the problem/situation What specific information do you need to know prior to designing your solution? What criteria/constraint details must you be informed about? Create several design possibilities Outcome: Sentences, Paragraphs, Lists, Charts

Explore Possibilities IOT POLY ENGINEERING I1-4 Explore Possibilities 3 Develop possible solutions to the problem / opportunity Come up with at least 3 solutions to the problems you must solve Include general sketches, then detailed sketches Does each possible solution satisfy the criteria and constraints? PLAUSIBLE SOLUTIONS! Outcome: Sentences, Lists, Charts, Sketches

Develop a Design Proposal IOT POLY ENGINEERING I1-4 4 Develop a Design Proposal Select an Approach Isolate, refine, and detail the best solution Integrate components Improve Detailed sketches Create the Proposal An explanation of your selected design How it works Required resources Detailed technical drawings Steps to make it Explanation of how it satisfies all criteria and constraints Outcome: Sentences, Lists, Charts, Sketches

Outcome: Tangible Object IOT POLY ENGINEERING I1-4 5 Make Model / Prototype MUST GET PROPOSAL APPROVED FIRST Model Used to communicate design ideas and processes. May be a small, large, or full scale model. Prototype A working model used to test a design concept by making actual observations and necessary adjustments. Outcome: Tangible Object

Test and Evaluate TEST TEST TEST TEST TEST TEST TEST TEST IOT POLY ENGINEERING I1-4 TEST TEST TEST TEST TEST TEST TEST TEST 6 Test and Evaluate Test model/prototype to ensure that it works as designed. Calibrate your model/prototype to satisfy all criteria and constraints. DOCUMENT YOUR TESTING PROCESS and RESULTS TEST TEST TEST TEST TEST TEST TEST TEST Outcome: Sentences, Lists, Charts, Sketches

Outcome: Sentences, Lists, Charts, Sketches IOT POLY ENGINEERING I1-4 7 Refine the Design Document any changes you make or need to make to your selected design. Implement those changes to your model / prototype. Retest. Outcome: Sentences, Lists, Charts, Sketches

Communicate the Solution IOT POLY ENGINEERING I1-4 8 Communicate the Solution Recreate the design proposal Include the refinements you documented in Step 7 Reminder – design proposal is an explanation of your final design: How it works Required resources Detailed technical drawings Steps to make it Explanation of how it satisfies all criteria and constraints

Classwork / Homework I1-4 IOT POLY ENGINEERING I1-4 FOT REVIEW Classwork / Homework In complete sentences, explain how the four design principles can be used to evaluate a design and how the principles are applicable to the engineering design process. Study everything covered in this class so far, including paper setup – quiz likely. When the first bullet is read, mention a bunch of common technologies so that students can’t take an easy way out. For example, say, “iPod, t.v., cell phone, car, video games, computers, internet.” It frustrates them and will get them thinking outside their usual box.
