Drill Analysis & Decomposition
ME-40, Engineering Design I
Professors Luisa Chiesa, Gary Leisk, and Dan Hannon
Spring, 2022
For this project, our group of 3 was assigned a mechanical hand drill to disassemble, analyze, and CAD. The purpose of the project was to gain a better understanding of the engineering properties behind a piece of equipment, practice computer aided design using Solidworks, and complete Concept of Operations and other analyses.
Part 1: Analysis
Components of this project included:
Overview of user centered design of Black+Decker drill
Notes on packaging
Documentation of first use
Knowledge Elicitation
External product review
Lists of off-nominal uses
Concept of Operations
Part 2: Decomposition
Components of this project included:
Pieces of this project included:
Decomposition of physical drill
Function structure diagram
SolidWorks CAD of drill, including internal parts
Part 3: Accessibility Redesign
This project was completed as a final group project for my Engineering Design course. We were given a persona for a young woman with cerebral palsy, and instructed to alter the design of a Black+Decker drill for her use.
As a part of the project, we:
Developed a risk matrix
Completed anthropometry considerations
Constructed a problem statement
Made a list of system & customer requirements
Finished market research & engineering considerations
Developed and subsequently narrowed down ideas
Determined weight factors & down selected
Re-designed drill
Developed drawing prototypes of finalized drill
