Abstract/Summary
This document outlines details of the Cal Poly-SeaSpine senior project collaboration for the force limiting handle with replaceable components. This document will cover a brief introduction of the project itself, background information about the problem, customer requirements and engineering specifications, ideation and concept selection, detailed design, description of testing and manufacturing plans, design verification and validation results, conclusions, and future work.
The design process included background research and scope identification, ideation, concept selection based on quality functions and customer requirements, detailed design, manufacturing, testing and iteration, and design verification and validation. Key specifications for the device included a force to break the device greater than the force to insert the spinal cage during spinal fusion surgery, 378.3 N, and less than the lower limit of the force to break the spinal cage, 923 N. The force to break the device was found to be 776 N, with upper and lower tolerance limits of 793 N and 759 N, which were well within the specified allowable range. Further details of data analysis and testing are included in Section XIII.
