Team Vision for Problem Definition Phase

During this opening phase, the team planned on creating the project definition and solidifying customer expectations. Not only were these accomplished, but preliminary assessments were also completed such as a House of Quality and a Risk Analysis. Furthermore a project plan was created. Due to the very open nature of the project, the plan won't be able to be fully completed until after brainstorming sessions have occurred and a final solution is chosen.

Project Summary

The current Kodak dry ink station (DIS) currently incorporates two “Oldham” couplings to transmit power and high quality motion from the gear box to the appropriate output shafts. These couplings currently experience two modes of failure: complete fracture, causing stoppage of the DIS, and misalignment, causing motion quality degradation. While fractures are easy to spot, misalignments are difficult to diagnose, and many Kodak Field Engineers are not comfortable in diagnosing and replacing misaligned couplings, so instead they will replace the entire DIS system. There is a significantly larger cost to replacing the entire DIS system when simply replacing the coupling would suffice. Kodak aims to lower the cost of maintenance and net replacements in the field.

The goal of this project is to design and build a test fixture that standardizes the measurement of key values of a coupling system within the DIS in order to better understand the modes of coupling failure, with the ultimate goal of minimizing maintenance cost for Kodak. The physical test fixture, along with any design documents, technical papers, final poster, and required code is to be the main deliverable to Kodak. All code compiled must be done in LabView and total project budget is not to exceed $4k. The project also must be completed by the end of Fall semester 2017.
