Meeting Agenda:

1. Strategies

   1. How to be a good mech member :^)

   2. Engineering Design Process

2. Mechanical Design Stages

3. Timelines

Strategies:

• Mech member = designer

  • they’re in charge of research and decision making

  • mech leads help with providing advice, intuition, and strategies for solving complicated problems

    • also useful for giving shortcuts, resources, or tips in finding those solutions

• Do good research and documentation; keep it organized!

  • this is useful for presentation, communication, review, and for other people to give you suggestions

• Engineering Design Process!!!

  • it’s a logical way to gather information and understand how you should

    • reach conclusions

    • communicate to others

    • see the impact of your work on the final product and stakeholders

  • ENGR100 - Alfano (Old/2014 Lectures) - YouTube

    • just look at slides

    • try to use the strategies that are suggested :^) they are logical and organized

    • Bend Fixture Design Project - Mechanical - Confluence (atlassian.net)

      • work term report example for bend fixture

      • includes problem definition, concept design, first iteration of detailed design, and some FEA

Mechanical Design Stages

• Problem Definition

  • Stakeholders

    • People who are involved with your project or interested in your project

      • Other people in the car assembly

      • Mentors / reviewers

  • Design Requirements

    • Nonfunctional

    • Functional

    • Criteria

    • Constraints

      • **should note loading conditions that you expect and justify them

  • Engineering Design Specification

    • Bill Materials

  • Manufacturing Plan

  • Fabrication + Assembly

• Prototyping (Small Scale or Scaled Down)

  • try to make it cost-effective

Timelines

• We will install trunk latch in Spring 2022 the latest.

• Concept Design = 1 month

• Detailed Design = 1.5 month

• DFMA = 0.5 month

• Installation = 1 week (whenever it will be installed)

Resources
