This project was for my Engineering Design course, taken in Spring 2023. We put class concepts into practice with a Handy Stitch portable sewing machine. We did so by evaluating the product design and function, taking the device apart, reassembling the device using CAD, and explaining our process through a simplified video walkthrough.
The objective for our project was to practice classroom concepts: knowledge elicitation, hierarchical task analysis, concept of operations, function structure, and CAD through examining and deconstructing a Handy Stitch portable sewing machine.
Our project began with evaluating the usability of the device through testing with each team member and observing someone outside of our class using the device. Along with considering affordances and off nominal use, we created a CONOPS analysis of the Handy Stitch. Then we took apart our device to examine all of the components and see how the device was assembled. We created logs of each internal component, its material, and suspected manufacturing process as well as a step-by-step guide to how the whole device was disassembled. I then recreated the deconstructed parts by measuring each dimension of each part then using Solidworks to model and reassemble the parts. To recap our whole project journey, I scripted and directed a video explaining each step taken so that a non-engineer could understand.
Our final deliverables were a 3D model of the Handy Stitch as well as a video documenting our process in understanding the device. I appreciate the opportunity this project gave me to practice my 3D modeling skills and incorporate my interest in video editing. It was a pleasure to collaborate with my teammates, whose flexibility and support made each step of the process seamless.
I will get back to you within three business days.
