and The Engineer’s Notebook 1.2 The Design Process and The Engineer’s Notebook

Words of the Day Target Consumer – A group, in which a product is designed for. Design Process – A systematic problem-solving strategy. Engineers Notebook – A notebook used to record the evolution of a product. It is sometimes used to prove who developed the idea with patent law suits.

Design Process Overview Introduction to Engineering DesignTM Unit 1 – Lesson 1.1 – Introduction to Design Process Design Process Define the Problem clearly Collect Data (Identify criteria and constraints.) Brainstorm (What’s already out there?) Develop a design proposal (Includes sketches, materials, time frame, cost estimation, etc.) Make a prototype or implement solution Test /Evaluate (Problem solved?) Modify/Refine There are many design processes that guide professionals in developing solutions to problems. The example that you see here is the design process that we will use for this course and the rest of the Project Lead The Way, Inc. courses you will take. Project Lead The Way, Inc. Copyright 2007

Rules for Brainstorming Introduction to Engineering DesignTM Unit 1 – Lesson 1.1 – Introduction to Design Process Rules for Brainstorming No criticism allowed!! Work for idea quantity, develop as many as possible. Everyone contributes. Remind students that all ideas are important ideas. ALL students must be able to contribute. Project Lead The Way, Inc.

What are some team-working skills? - Dependable (Will you do your portion and correctly?) - Collaboration (Work well with others? Control freak?) - Task allocation (Do you evenly distribute the work?) - Conflict resolution (Will you talk/listen to work it out?) - Communication (Do you listen/speak effectively?)

Design Activity: Objective: In a team of two, design something that will hold a wooden triangle (point down), for 10 sec. You can’t hold it with your hand. Materials: 2 Sheets of printer paper 2 Rubber bands 1 strip of tape a foot long (12inches) Ruler 1 wooden triangle 1 table - 2nd step: Brainstorm, quantity….not quality! - You must find 4 WORKABLE SOLUTIONS!! - Each person is responsible for two ideas, draw the sketches on your notes.

Aptera The Aptera, the three-wheeled energy efficient car. Available in either an all-electric or a hybrid model. You get a top speed of 95 MPH - seats 2 comfortably A solar panel on roof powers climate control system. The hybrid model - 230 mpg - $29,900 http://www.youtube.com/watch?v=QwHm6aefGLQ

Design Criteria Designing normally requires consideration for: Function (what’s its purpose, what does the design require) Cost (should I reconsider the materials to reduce cost) Aesthetics (appearance, does it look nice) Material (what will it be made of, what’s appropriate) Shape (does it have to be a certain height or size)

The Engineer’s Notebook How do engineers communicate with each other? Introduction to Engineering DesignTM Unit 1 – Lesson 1.1 – Introduction to a Design Process The Engineers Notebook: Written ideas/Research Sketches (preferably annotated) Changes made along the way with dates Calculations/Measurements We are not looking for artists when sketching, just proper detail of the thought or idea.
