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

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

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

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

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

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

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

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

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

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

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
