Abstract/Summary

Calculated Industries, a company that specializes in construction products headquartered in Carson City, Nevada, has sponsored the Heating Lanyard to Warm Body Core senior project. The objective of the project was to design and manufacture a body core heating device that will be used by construction workers to keep warm in cold environments. The goal is to create a device that is safe, comfortable, and temperature controllable. Our team consists of four mechanical engineering students at California Polytechnic State University, San Luis Obispo. Research was performed to analyze current products in the market, analyze how to best provide heat to the body, and determine a product idea to disrupt the current market. Our team designed, manufactured, and tested a body core heating device that will be used by construction workers to keep warm in cold environments. The power and body subsystems are explored and justified by ergonomic and temperature tests on all prototypes. The final prototype exhibits desired specifications such as reaching a high surface temperature of 141􏰀F, lasting a minimum of five hours, and weighing 0.56 pounds. A detailed procurement plan of materials necessary to build a single concept prototype was provided and indicates a total cost of $24.52, not including labor costs. However, with bulk pricing, we expect this number to decrease to a wholesale cost of $10.70 per unit.
