Introduction to DESIGN AND THE DESIGN PROCESS
Design Process in IED
The Design Process: Is the organized and orderly approach to solving problems and involves 6 steps: Define the Problem Generate Concepts (Brainstorming) Develop a Solution Construct and Test a Prototype Evaluate the Solution Present the Solution Any stage in the process can send you “back to the drawing board”
The Design Process:
Phase One: Define the Problem or Problem Identification Identify and/or recognize the problem Solve the problem AND meet the customers needs or desires Must also meet government standards Even existing products are revised and updated according to the user’s desires and because of new technology. What are some examples you can think of?
Phase Two: Generate Concepts or Ideation Collection of ideas: Brainstorming Technical sketches
Phase Three: Develop a Solution / Analysis of Design Best solution(s) selected….usually involves AutoCAD/Inventor Consider cost, manufacturing, repair, environmental impact, power used, new technology
Phase Four: Construct and Test a Prototype 3D CAD drawings Prototype 3D Printing Testing using software or prototype
Phase Five: Evaluate the Solution What did Testing Show? Other Questions Provides Value
Phase Six: Present the Solution / Production or Working Drawings Show all views of product Dimensions Tolerances Notes Assembly drawings

Two distinct lines of graphic representation Artistic To display the aesthetic, philosophic, abstract or even emotional ideas Technical To represent the design of objects or buildings to be built. Both can actually be used together for architects, designers, engineers, etc. What do you feel is your strongest?
Technical Drawings Serve one to three purposes: Visualization Communication Documentation

The 3 “L” s: Line types Line weights Lettering
Line Types & Weights Visible (outline) Section (hatch) Hidden Center Dimension & Extension lines Cutting plane Break Phantom
Rules of Thumb Use a straight edge! Start a line with clear, crisp and definite mark Rotate pencil as you go across End with same bold, crisp definite end The contrast in different line weights is in the width of the line, not in the darkness of it DO NOT do short, light sketch lines!!!
Lettering Legible Proportionate Typically 1/8” Guidelines used Font: Gothic, Romans, Inclined or Italic Typically all caps Uniform, consistent Uniform spacing
