Credits 3

Pre-requisites - None

Core/Elective - Core Course

To provide students’ knowledge and understanding of different aspects of product design and development, ergonomic principals and material selection techniques so that they will be ab le to follow a structured approach in the invention/innovation of products.

At the end of this course, students should be able to:

1. Write a design brief for a given product initiative.

2. Prepare the design specifications by using Quality Function Deployment which ensures that customers’ requirements are met and takes into account the products of competitors.

3. Create concept designs and select the optimum design by using standard evaluation techniques.

4. Select the material, processes and calculate necessary forces, critical areas, sizes, stresses and analyze the design for the above design specifications.

5. Generate the detailed drawings for a given product.

1. Introduction: Why we need product designs, Who designs and develops products, Challenges of product development Standards, Generic product development process, Steps of product design

2. Motivation or Need Stage and Design Brief: Identifying customer needs, design brief, design specifications Quality Function Deployment (QFD)

3. Concept Design: Brainstorming, Synaptic, Objective trees, Morphological charts, Weighted objective method

4. Embodiment Design: Product architecture, parametric design, analysis, optimization Aesthetics Process selection

5. Detail Design, Documentation, and Development: Important features in part drawings, assembly drawings, and layout drawings, prototyping techniques and methodologies

6. Ergonomics: Posture, anthropometrics, Working environment

7. Material Selection: Mechanical behaviours, failures Performance indices, Ashby charts
