FINAL PROJECT

Computer Aided Design

Assignment


Document a final project masterpiece that integrates the range of units covered, answering:
  • What does it do?
  • Who's done what beforehand? ✓
  • What sources did you use?
  • What did you design?
  • What materials and components were used?/Where did they come from?/How much did they cost?
  • What tools and processes were used?
  • What questions were answered?
  • What worked? What didn't?
  • How was it evaluated?
  • What are the implications?
  • Prepare a summary slide and a one minute video showing its conception, construction, and operation

Your project should incorporate 2D and 3D design, multiple additive and subtractive fabrication processes, electronics design and production, embedded microcontroller design, interfacing, and programming, system integration and packaging

Final Project Idea

Idea: Smart HangBoard

A rock climber's ideal training partner is a SMART hangboard. It includes LED lights indicating which holds to use, a load sensor-activated timer, and a mobile app for programming and tracking workouts. Additionally, an AI app can suggest hangboard routines tailored to your climbing level and past workouts. The hangboard easily attaches to your backpack, making it convenient for approaches, so you can use it to warm up for your toughest climbs.

What Has Been Done Before

Climbro developed a wall-mounted hangboard with interchangeable holds and an AI powered personal trainer. Additionally, the board has the ability to evaluate finer strength....but it is not clear what tech they are using to evaluate finger strength.

Moon Boards are a standardized climbing wall controlled by an app. Anyone can download the app, connect to a Board via Bluetooth, and try different climbs or create their own. In order to know which holds to use different colored LEDs turn on to identify the start, end, and all the holds in between. A few other companies have jumped on the LED Climbing Wall trend such as Tension Climbing and Kilter

Finger strength training by using a hangboard is prevalent in the climbing community with lots of different hangboards on the market. Hereis a link to a review of The Best Climbing Hangboards of 2025. My husband and I have the Porblem Solver Hangboard and Metolius Project hangboards

Initial Concept

Looked at Two Stones HangBoard to get an idea for dimensions I used oneNote to sketch out some ideas.

Solidworks Models

The Hangboard

This hangboard features a variety of hold sizes ranging from 18mm to 30mm, with a 35mm mono.

The System

Dimensions: The hangboard can be mounted on a pull-up bar or a sturdy horizontal tree branch.

Materials Selection

What type of Wood? I read this blog to get an idea of what type of wood to use. They recommended either beech, birch, oak, or another hardwood. I found a butcher block of Hard Maple Edge Grain and ordered two. Unfortunately, the butcher blocks will not arrive until 24 October.
