INTRODUCTION TO ENGINEERING DEIGN
What is IED?
Students dig deep into the engineering design process, applying math, science, and engineering standards to hands-on projects. They work both individually and in teams to design solutions to a variety of problems using 3D modeling software, and use an engineering notebook to document their work. (www.pltw.org)
Puzzle Cube
DescriptionIn this project, I had to design a 3D Puzzle Cube using simple modeling features.
Constraints:
Design ProcessI first made sketches of each piece. I then used Autodesk Inventor to model the parts and build an assembly. After modelling each piece and the assembly, I made orthographic drawings of each piece and the assembly. I then used driven constraints to make the animation below.

Reverse Engineering
Description
Reverse engineering is the process of taking a product, disassembling it, and learning how it works. Reverse engineering is important to learn about problems that were not fixed earlier in the design process. For this project, I worked in a group to reverse engineer a skateboard.
Visual and Functional Analysis
The first step in reverse engineering is visual and functional analysis. During visual and functional analysis, no disassembly is performed. This step involves simply looking at the product as a whole. Visual analysis includes looking at the elements of design of the product. During functional analysis, one hypothesizes how the product works and why.
Disassembly
Once the visual and functional analysis is finished, the next step is disassembly. This is where the product is taken apart into its components. During disassembly, it is important to take note about how the pieces fit together. This is to ensure that the reverse engineered parts will go together correctly. Once disassembly was finished, my team and I decided who would reverse engineer each piece.
Modelling
After disassembly, we modeled the individual parts and made orthographic drawings of each part. We also virtually reassembled the parts into an Inventor assembly.
IED Final Project
DescriptionIn this project, students had to find a problem and develop a solution. This was a group project where at least one group member was in a different class. The goal was to learn about working with a group even when you have limited chances to be with them in person.
ProblemThe problem my group and I choose was the increasing prevalence of laptop burns. According to the Centre for Burn Care, burns can occur on skin at temperatures as low as 111.2° F. The temperature in laptops can get up to 212° F if used for longer than two hours. There has been an increasing prevalence of laptop burns every year according to the U.S. National Library of Medicine. A need has developed for a solution to prevent laptop burns.
SolutionOur solution was the Go Anywhere Desk. The Go Anywhere Desk is similar to a conventional brief case but has a desk that can be unfolded out of the top to form a writing surface and area for a laptop and mouse. While the desk part of the case flipped up, the user will still have access to areas within the case for storage and organization.
