PCB & ME-EE Interfacing
I was given the opportunity to serve as the ME lead for an unreleased product with the intent of replacing several existing fixtures. At the early stages of this project, I primarily focused on mechanical design, modifying parts to meet new intended functions, as well as working with the EE team to model components for PCB interfacing.
ELECTRICAL COMPONENT MODELLING
In order to create an accurate model of the new fixture including both the mechanical housing and PCB, models of the individual electrical components were needed. The EE team provided specifications for various components as new layouts and parts were tested.
​
I created accurate models in SolidWorks based on the provided dimensions, a few of which are shown here, which were later used in combination with mechanical components to verify overall design.
TOLERANCE STACK-UP ANALYSIS
Throughout the initial design stages, several tolerance stack-up analyses were performed in order to ensure that parts would not overlap or interfere with the intended functionality of the product in the event that each component was not manufactured perfectly to specification.
​
I did all of these analyses by hand, shown in the examples below, some of which led to further design modifications or changes to the PCB layout.
PART MODIFICATIONS
Most part modifications were based on a necessity for functionality or aesthetics, while others were based on standardized requirements. As I began to integrate the Electrical and Mechanical components, I became aware of UL wiring compliance regulations, several of which allowed me to explore new design possibilities.
​
The particular aspects of wiring that I investigated included bend radius for mechanical fit and insulation requirements, the latter driving potential design changes to route wires separately from a mechanical standpoint.
Mechanical Engineer
PAX is an electronic vaporizer company that creates next-generation consumer devices while supporting social justice, access, and equity in the industry. As a full-time engineer, I've been involved in various stages of the product design process including early-stage development, design for manufacturing, and validation testing. My project work has not only improved my technical skills but has introduced me to the importance of global supply chain and manufacturing.
Associate Mechanical Engineer
Continuum is a global innovation design firm that develops products, services, and experiences to improve people’s lives. My final co-op placement allowed me to work across the Mechanical and Electrical Engineering teams on several contracted projects, focusing on manufacturing development and validation. Due to the COVID-19 pandemic and government-mandated work-from-home order, the scope of my co-op was ultimately limited.
