Define Problem: Design Specification Generate Ideas: Brainstorm Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Concept Development Define Problem: Design Specification Generate Ideas: Brainstorm Research Search published literature Journals, conference proceedings, trade magazines, government reports, etc. Thomas Register of American Manufacturers Develop Multiple Product Concepts In order to identify the best solution, consider many different solutions. Begin with the design specification. With the product requirements in mind, generate as many potential ideas as possible through brainstorming or other methods. Continue to research existing products to solve the specific problem being addressed. Also consider products that may have similar functions in another domain. Sift through the concepts generated and identify several ideas that seem promising for further development.

General description of the product Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Product Concept General description of the product Explanation of the technology and working principles Justification – Concise description of how the product satisfies customer needs and the specifications Sketch or 3D model of product A product concept is not a complete design, but it should be detailed enough to allow evaluation and comparison among ideas and existing solutions. Present each concept using a visual representation (e.g., sketch or basic 3D model) and a written description of the product and how it satisfies the customer’s needs.

3D Representations Oblique Isometric Perspective Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Sketching Skills A picture is worth a thousand words 3D Representations Oblique Isometric Perspective Although 2D sketches are sometimes sufficient to represent simple objects, being able to represent ideas with 3 dimensional sketches is an important skill for designers. It enables them to communicate ideas to others, especially non-designers who may have difficulty visualizing an object from a verbal description or a 2D sketch. Several types of three dimensional sketches are commonly used in the design process to produce realistic looking representations of ideas. Some of these types of sketches, sometimes called pictorials, include oblique, isometric, and perspective sketches. We will briefly review each of these types of pictorial sketches in the following slides.

One-point perspective views are constructed using one vanishing point on the horizon. All depth lines recede to the single vanishing point A one-point perspective view is the simplest perspective view to create but can make small objects seem larger than they actually are.

The level of detail of the sketch and annotations necessary to describe the product varies depending on the product and its complexity. STAPLER DESIGN TOOTHBRUSH DESIGN

Product Concept Documentation Product Description Describe the purpose and appearance of the design concept. Operation Describe the intended operation, including inputs, outputs, and internal processes. Justification Explain how the design concept satisfies customer needs and meets the design specifications.
