Mechanical Design & Product Development Process

Basic Ideas & Concepts Behind Developing Products Related to Mechanical Engineering

By Mufaddal Rasheed | in Online Courses

Product development is how a mechanical product is realized from just an idea into a fully detailed entity ready for production. This course attempts to cover that process at an introductory level covering all the key concepts, ideas, and details from a perspective of a mechanical design engineer. It's structured in a way as to build on the product development process step by step. From the way an Idea is generated, incubated to how a concept is developed, evaluated, how specifications are created and set towards the system design of a product, followed by an overview of activities in detailed design and prototyping.
