Abstract/Summary

The current design of jeepneys used for public transportation exposes its drivers to ergonomic risks and unnecessary tasks. Based from the needs analysis conducted by the group, the dimensions of the workplace are not measured according to the 5th-95th percentile of the driver's population. It resulted to awkward driving postures which were identified in the RULA with scores of 3 and 4 for hands on steering wheel and hand on shifting gear, respectively. The action of reaching backward as evaluated from the task analysis was proven to be unnecessary and through biomechanics it was verified that it exceeds the allowable shoulder abduction of 30 degrees. To address the ergonomic needs and potential occupational hazards of the drivers, an analytical prototype of jeepney driver's workplace and a physical component for the faring task were developed. The purposes of the designs were to improve the awkward postures and eliminate the unnecessary tasks that are done by the drivers. In generating the analytical prototype, the group followed the design process that was suggested by Sanders (1993). On the other hand, different design considerations were included in making two alternatives for physical faring component and two alternatives for the inclusion of money holder in the analytical prototype. By using the Pugh's method of screening and selection, the Adjustable Back Slide was chosen for the faring component design. Before arriving at the final physical prototype, it underwent into four iterations to refine the design. After being manufactured, the prototype was tested and reevaluated to establish its improvement. A secondary needs analysis was done. From the results of RULA, biomechanics and task analysis, the prototype achieved its objective. This design was also embedded on the generated analytical prototype of the whole driver's workplace in CATIA. With the use of the mannequin and its different positions, the objective of arriving at a modified workplace design was accomplished. Improvements from the current design were also attained. Additional concepts were cited for the recommendations for further study of the faring component and different topics were also suggested for a different perspective of the study.
