Overview
Stemco Inc. produces aftermarket products for the 18-wheeler industry to increase safety, performance and fuel efficiency. As a co-op, I strengthened my skills in lean manufacturing techniques, statistical process control, product design, and systems engineering. I worked on several products ranging throughout the development lifecycle: planning, design, implementation, maintenance, and analysis.
Planning and Design
For a new product (an electronic trailer tracking system) in the conceptual stage, I was involved with the planning of tests and had full responsibility for the mechanical design. The system had to be waterproof, durable, relatively light and easily accessible for maintenance. I modeled the entire system in SolidWorks, purchased components, manufactured the first prototype, and conducted preliminary tests. My design proved effective as it passed all tests.

Implementation and Maintainence
For a new adaptor product (AERIS outlet vent) that was ready for the manufacturing stage, I helped with the implementation and maintenance by constructing a workstation in the most applicable location along the AERIS assembly line. For this new product, I wrote the assembly instructions while utilizing lean manufacturing techniques to standardize, sustain, and organize the process. Furthermore, I ensured that the workflow processes and instructions did not allow misassembly, poor quality construction or human error to be an issue. I performed statistical analysis to eliminate defective hardware, specified torques, and created product holders to establish a workstation that produced flawless components.

The AERIS product is an automatic tire inflation system that is installed onto 18-wheeler hubs. I designed and built the workstation that assembles the adapter vent.
Analysis
For the entire assembly of the TrailerTail product, extensive analysis had to be performed. I helped analyze where nonconformities occurred in the process including the orientation of panels, the selection of fasteners and placement of fasteners. I conducted root cause analysis and drew conclusions backed by statistically obtained data. Through my work I learned how to utilize the Six Sigma methodology of define, measure, analyze, improve and control.




The TrailerTail product is an aerodynamic fairing installed onto the rear ends of semi-trailers to increase fuel efficiency. One of my tasks was revising and improving the instructions, that the shop floor workers followed.
