Abstract/Summary

Cepheid is a molecular diagnostics company that has assigned our senior project team to design a system that automates the current manual transportation of samples between two laboratory rooms. With the focus of retaining the sanitary integrity of both the samples as well as the initial cleanroom, also referred to as the packaging laboratory, our team has designed an extension of the current passthrough that will contain all other subsystems. In order to automate the transportation of the samples, the design employs a track and trolley system to be purchased and mounted within the passthrough. A verification prototype was built and tested to ensure the design would work as intended, modeling a five-foot section of the entire sixty-foot path. This prototype features an interlocking system to eliminate any potential for backflow between lab rooms. Samples are carried in a hanging bag that the team has designed to not spill any of the cartridge’s contents. Additionally, a virtual model was made and used to perform varying load tests to prove the validity of the materials selected for the passthrough. While effective, the proposed design could be improved in efficiency, though regardless of the decisions made by Cepheid regarding implementation, the designed passthrough extension and interlocking system could be used in any industry backflow prevention scenario.
