IOT POLY ENGINEERING I1-4 PROCESSES Management –Planning and scheduling –Organizing (e.g., salaries) –Actuating (e.g., marketing) –Controlling Design –Engineering Design Process –Problem Solving Process Production –Communication –Construction –Energy and Power –Manufacturing –Transportation FOT REVIEW

IOT POLY ENGINEERING I1-4 Management Process HOW and by WHOM will it be… designed, manufactured, paid for, operated, maintained, replaced, disposed of, advertised and sold, operated, taken care of?

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.

IOT POLY ENGINEERING I1-4 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 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 Design Process

IOT POLY ENGINEERING I1-4 Similar steps can be grouped: 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 Design Process

IOT POLY ENGINEERING I1-4 Design Process as you should know it: 1.Define the Problem 2.Brainstorm, Research, Generate Ideas 3.Explore Possibilities 4.Develop a Design Proposal 5.Make Model/Prototype 6.Test and Evaluate 7.Refine the Design 8.Communicate the Solution Design Process Next: an outline of these steps of the Design Process – use this all year

IOT POLY ENGINEERING I1-4 1.Describe the situation (that needs a tech. solution) a.What must your solution accomplish? b.What is the need or desire? 2.Establish the criteria and constraints under which the solution must operate a.What are solution requirements (criteria)? b.What are the limitations on the solution (constraints)? Define the Problem Outcome: Sentences, Paragraphs, Lists

IOT POLY ENGINEERING I1-4 1.Gather information – Obtain background information needed to begin developing solutions to the problem/situation a.What specific information do you need to know prior to designing your solution? b.What criteria/constraint details must you be informed about? 2.Create several design possibilities Outcome: Sentences, Paragraphs, Lists, Charts Brainstorm, Research, Generate Ideas

IOT POLY ENGINEERING I1-4 Develop possible solutions to the problem / opportunity 1.Come up with at least 3 solutions to the problems you must solve 2.Include general sketches, then detailed sketches 3.Does each possible solution satisfy the criteria and constraints? Explore Possibilities Outcome: Sentences, Lists, Charts, Sketches

IOT POLY ENGINEERING I1-4 1.Select an Approach Isolate, refine, and detail the best solution a.Integrate components b.Improve c.Detailed sketches 2.Create the Proposal An explanation of your selected design a.How it works b.Required resources c.Detailed technical drawings d.Steps to make it e.Explanation of how it satisfies all criteria and constraints Develop a Design Proposal Outcome: Sentences, Lists, Charts, Sketches

1.Model Used to communicate design ideas and processes. May be a small, large, or full scale model. 2.Prototype A working model used to test a design concept by making actual observations and necessary adjustments. Make Model / Prototype Outcome: Tangible Object IOT POLY ENGINEERING I1-4

IOT POLY ENGINEERING I1-4 1.Test model/prototype to ensure that it works as designed. 2.Calibrate your model/prototype to satisfy all criteria and constraints. DOCUMENT YOUR TESTING PROCESS and RESULTS Test and Evaluate Outcome: Sentences, Lists, Charts, Sketches

IOT POLY ENGINEERING I1-4 1.Document any changes you make or need to make to your selected design. 2.Implement those changes to your model / prototype. 3.Retest. Refine the Design Outcome: Sentences, Lists, Charts, Sketches

1.Recreate the design proposal 2.Include the refinements you documented in Step 7 3.Reminder – design proposal is an explanation of your final design: a.How it works b.Required resources c.Detailed technical drawings d.Steps to make it e.Explanation of how it satisfies all criteria and constraints Communicate the Solution IOT POLY ENGINEERING I1-4

Design Process 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 IOT POLY ENGINEERING I1-4

Classwork / Homework 1.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. 2.Study everything covered in this class so far, including paper setup – quiz likely.
