Development of an Automated Seat Dimension Evaluation System 2019-01-0401

Seat dimension is one of important factors affecting a driver’s seating comfort, fit, and customer satisfaction. In this regard, seat engineers put tremendous efforts to evaluate seat dimensions of a product seat until the dimensions are consistent with the design reference in computer aided design (CAD) model. However, the existing consistency evaluation process is heavily relying on seat engineers’ manual tasks which are highly repetitive, labor intensive, and time demanding. The objective of this study is to develop an automated system that can efficiently, and accurately measure seat dimensions. By using the developed system, the evaluation time for comparing 18 seat dimensions between CAD and scan models has been substantially reduced by less than 1 minute, which is 99% time saving compared to 2 hours in the existing manual process. In addition, the seat dimensions can be more repeatably measured than the manual measurement based on invented algorithms. In conclusion, the developed system is particularly useful not just time saving, accuracy, and repeatability, but also constructing a database of seat dimensions for better data management and benchmarking with other vehicle-seats.
