Abstract (eng): | PURPOSE: To create a method for evaluating and understanding perceived mechanical quality in products. While the method can be applied to any mechanical quality purpose, this thesis addresses the example of bistable slide mechanisms in mobile phones. MATERIALS AND METHODS: Proposed herein is a method for evaluating perceived mechanical quality using sensory panels and quick individual vocabulary profiling, a variant of sensory profiling. Included in the proposed method are sensory evaluation theory, testing procedures, and data analysis methods. The main result of this thesis is a conclusion of whether or not quick individual vocabulary profiling is an appropriate tool for evaluating perceived mechanical quality. RESULTS: After completing a complete iteration of sensory profiling using a panel of 13 persons, the thesis has shown that quick individual vocabulary profiling is an appropriate and reasonable means of evaluating and understanding perceived mechanical quality. In addition, this implementation of quick individual vocabulary profiling gives relatively quick and concise results. Furthermore, the results show with a reasonable degree of certainty that a degree of consensus was achieved between different assessors and some clear trends have emerged. CONCLUSION: Quick individual vocabulary profiling combined with various analysis techniques has been conclusively proven to be a possible solution for evaluation perceived mechanical quality of bistable slide mechanisms in mobile phones. |
