Engineering Design with CAD

This comprehensive guide outlines the engineering design process tailored for the FIRST Robotics Challenge. It emphasizes the importance of defining the problem, generating specifications, and prioritizing design concepts. Participants will learn to brainstorm, prototype, and iteratively develop their designs using Autodesk tools such as SketchBook and Inventor. Key functional requirements, constraints (including time and budget), and trade-offs are analyzed to improve robot performance. This training equips students with essential skills and knowledge for successful engineering projects.

Presentation Transcript

  1. Engineering Design with CAD Fusion FIRST training 2011

  2. An Engineering Challenge(some material excerpted from John V-Neun’s 2009 presentation) • Functional Requirements • Goals and objectives • Constraints • Physical (dimensions, weight) • Time • Money • Tradeoffs

  3. The Engineering Process • Define the problem • Make sure it’s the right problem! • Generate specifications • Use the requirements and the constraints • Set priorities • Design concepts • Brainstorming

  4. The Engineering Process • Prototype • Goal is to learn • Choice • Every choice results in some loss • Detailed Design • Build! • Document

  5. The Engineering Process for FIRST • Design • Discuss concepts and Prototype • Analyze and Adjust your design • Prototype… • : • Detailed Design • Manufacture • The process is iterative.

  6. Week 1 - Let’s Just Build!  • But now… • Robot is too heavy • It’s too big • The parts don’t fit in the allocated space • Too fragile • Not easily fixable • Doesn’t perform the task well • Rework; waste resources • Week 6 - I wish I had designed 

  7. The Engineering Process – Autodesk Products Define the problem Generate Specifications Set priorities Design concepts - SketchBook Prototype – Inventor Fusion Choice Detailed Design – Inventor Build! Document – Inventor Publisher
