Validation Testing
Over six months, I worked on a wide range of products at different stages of development. At every stage, I conducted engineering validation testing, designing and constructing test fixtures, analyzing data, and summarizing into formal presentations and written reports.
THERMAL TESTING
With no access to pre-made OTS parts, I constructed K-Type thermocouples by arc welding two dissimilar electrical conductors using a small carbon rod. I experimented with different methods of application based on research and testing conditions.
​
Common practice involved super glue and an accelerator for quick or high-volume tests, silver solder for crucial contact points, thermal tape for external applications, and thermal grease for the most accurate results. All tests were performed under controlled conditions using a DAC and BenchLink Data Logger, and results drove future engineering design considerations.
WATER INGRESS TESTING
Water ingress testing was often performed for internal validation before products were sent out for external testing. I was responsible for designing a variety of tests across several products to ensure compliance with IP ratings.
​
Tests were constructed based on formal requirements and included visual markers such as color-changing water-indicator stickers and paint. Important considerations included water pressure, torque specifications, impacts of heat and light, as well as safety precautions such as water-proofing of cables and use of a GFCI
LOAD & PULL-FORCE TESTING
Several products and their accessories required some load or pull-force testing to ensure that normal customer use, exposure to weather conditions, and wear over time does not impact the integrity of the product or the overall user experience. I designed several tests, modifying components and utilizing testing equipment like a force gauge to ensure the expected functionality of our products.
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.
Mechanical Engineering
R&D Co-op
Haemonetics Corporation is a global leader in blood management solutions, producing a wide variety of devices and consumables primarily focused on blood processing systems and plasma collection. My first co-op placement allowed me to work towards product development across the mechanical, electrical and systems engineering teams as well as gain exposure to advanced laboratory procedures and nano-dispensing technologies.
