1 The Design Process Drawing And Design For Production Engineering

2 What is Designing? It is simply translating ideas into reality. It is a technical form of problem solving. Provides a plan to create, implement, evaluate, and improve a product or process.

3 The Design Process Identify Problems & Opportunities Framing a Design Brief Investigation & Research Generating Alternative Solutions Choosing a Solution Developmental Work Modeling & Prototyping Testing & Evaluating Redesigning & Improving

4 Identify the Problem Identify and define the problem. This step involves investigating the needs and opportunities. The problem must be real and clearly stated. survey/market research accident complaints need identified

5 Framing a Design Brief Develop the “Design Brief”“Design Brief” This step involves clarifying the results you want to achieve Stating pre-determined Specifications and criteria such as: time, cost, size, shape, materials, users, place of use, and special functions should be listed.

6 Design Brief ( 2 Parts ) Give an introduction to the solution that you plan to implement. Restate the identification in a manner that reflects a solution. List anticipated specifications and guidelines that the solution must follow. This step often leads back to redesign of part or all of the solution and the process begins again. Tests should be conducted on models and prototype.

7 Investigation and Research Gather all pertinent information for future reference. This step should involve the following resources: Human factors Ergonomics Existing devices and systems Existing knowledge and solutions

8 Generating Alternative Solutions Explore possible solutions. This stage involves brainstorming and ideation. (some initial sketching of thumbnails is needed) This step involves searching for solutions and information. Several different solutions should be explored. Investigation may help clarify need or problem. (Brainstorming)(Thumbnails)

9 Brainstorming Record your thoughts and ideas with quick notes or sketches. Discuss these with your team members. Record any tangent concepts. Investigate any additions, sources, or ideas discussed. All solutions and ideas are welcome.

10 Thumbnail Sketches Recorded ideas with quick sketches Initial ideas with little thought to scale or accuracy Can include some initial notes or ideas.

11 Choosing the Optimal Solution(s) Assess the alternatives. Refinement of preliminary ideas. Annotated SketchesAnnotated Sketches This step involves assessing all the solutions generated and choosing the best one(s) Implement the Design MatrixDesign Matrix The best choice or choices move on to step 6

12 Annotated Sketches Refine your preliminary thumbnail sketches. Add notes and comments Weigh your specifications

13 A Design Matrix Using a matrix, select a workable solution

14 Developmental Work In this step you will further develop your optimal choice(s). More support research… You will develop your initial drawings.drawings. This step involves experimentation with: different materials mechanical systems (kinematics) Fastening techniques Shapes and sizes preliminary models

15 Drawings Working Drawings Assembly Drawings ( Choose one of the above )

16 Working Drawings A drawing that supplies information and instructions for the manufacture or construction of machines and structures. Typically shows individual views of the object.

17 Modeling and Prototyping The last stage of a product prior to testing and production This step involves the development of models, and prototypes. (Types of Models)

18 Prototyping of Design Solutions Models are used as representations of system design for refinement and testing of the product. (3 types) Appearance - Looks like Model Function - Works Like Model Prototype - Looks like Works like Model

19 Evaluate the results. This step involves testing the solution and assessing the process. Demographic testing Survey groups Scientific testing and analysis Testing And Evaluation

20 Assembling Drawing A drawing showing the product in its completed state. An exploded assembly is a very common type of assembly drawing. It shows the individual pieces of the object unassembled, and it shows the pieces aligned to each other demonstrating how to assemble the object.
