Stapler Design Project
​
McGill University
Introduction
​
Staplers are one of the most applicable tools used in government, business, offices, work places, homes and schools. With many parts housed in a cover, these mechanical devices are incredibly intricate in their design.
Purpose
​
The purpose of this project was to investigate and understand the Design for Assembly (DFA) process for an intricate product. This project consisted of two parts, designing a basic stapler and applying DFA modifications to match industry standards.
Constraint Requirements
​
-
All locking mechanisms must be standard​
​
-
DFA analysis using the Lucas method must fall under the threshold
​​
​
Functional Requirements
​​
-
The stapler must contain realistic locking mechanisms and attachments
​
-
The materials used must align with real world designs​
​
Initial Design
​
Initially, a basic stapler design was provided in the SolidWorks CAD software. The stapler included a handle, anvil, base, magazine, and locking mechanisms.
Final Design
​
Using the Lucas method, DFA was analyzed for all components on the stapler. From the table below, It was noted that the handling index was 10.9 and the fitting index was 14.4
An exploded assembly of the stapler was then created to illustrate the assembly process.
​
After using the Lucas Method, the components of the stapler were analyzed to identify DFA modifications. These are detailed in the table below.
