Tech 190A Week 10 Lecture
Introduction to New Product Development
(Synthesis)

2. Synthesis Involves: Specification of materials
Addition of geometric features
Inclusion of greater dimensional details to conceptualized design
Removes (filters) cost-adding features and materials
Employs DFM and DFA to ensure good design
About 70% of manufacturing cost is fixed in steps 1 and 2 activities

3. Specification of Materials
Material types
Material mechanical, electrical, and chemical properties
Material shape
Material form
Material manufacturing properties
Material sizes or dimensions
Material cost
Others

4. Addition of Geometric Features
Part or component features such as:
Holes
Boss
Rib
Grooves
Fillets
Letters
Finish
Curves
Angles
Others

5. Inclusion of Greater Dimensional Details to Conceptualized Design
All dimensions are added at this time
Key dimensional tolerances are added at this time
Others

6. Removal or Filter of Cost-adding Features and Materials
Unnecessary manufacturing processes
Costly manufacturing processes
Combining of processes
Less expensive materials
More environmentally-friendly materials
Easily available materials
Others

7. Employs DFM and DFA to Ensure Good Design
Design for manufacture
Design for assembly
Others

8. The Key Role of Stories and Prototypes in Design Thinking
Chapter 7
The Key Role of Stories and Prototypes in Design Thinking

9. What is a Story?
Stories allow concepts to be visualized and experienced before they have been designed and developed
Stories told from the viewpoint of the end user of the product are the foundation of business-to-consumer concept
They should be short
They should start by introducing the context

10. What is a Story?
They should describe the problem as experienced by a representative person or sets of people
They should be limited to a time period in which an end-to-end experience of the user occurs
They should be supported by sensorial information like sketches, photos, renderings, prototypes, and example products
Common formats for telling stories are spoken storytelling, acting out in person or video, diagramming and storyboarding, and written text

11. What is a Prototype?
Prototypes are created to answer a set of questions, test assumptions, and demonstrate how something works or could work
They are tools to learn and to communicate
They make a concept tangible and allow it to be shared and developed with people who are not engineers or designers
Prototypes can be physical, simulation, video, and digital animation
