4 Define Problem: Design Specification Generate Ideas: Brainstorm Presentation NameCourse NameUnit # – Lesson #.# – Lesson NameConcept DevelopmentDefine Problem: Design SpecificationGenerate Ideas: BrainstormResearchSearch published literatureJournals, conference proceedings, trade magazines, government reports, etc.Thomas Register of American ManufacturersDevelop Multiple Product ConceptsIn 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.
5 General description of the product Presentation NameCourse NameUnit # – Lesson #.# – Lesson NameProduct ConceptGeneral description of the productExplanation of the technology and working principlesJustification – Concise description of how the product satisfies customer needs and the specificationsSketch or 3D model of productA 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.
6 3D Representations Oblique Isometric Perspective Presentation NameCourse NameUnit # – Lesson #.# – Lesson NameSketching SkillsA picture is worth a thousand words3D RepresentationsObliqueIsometricPerspectiveAlthough 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 pointA one-point perspective view is the simplest perspective view to create but can make small objects seem larger than they actually are.One-Point Perspective

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