Concurrent Design Method for Product Design of Wheelchair Tiedown and Occupant Restraint Systems (WTORS)

EasyChair Preprint 4705

Abstract

Design goal orientation is an important indicator of product research and development. Concurrent design Strategy are introduced to coordinate relevant departments to communicate and implement product design processes through clear product design goals, so that the research and development process can increase efficiency, control costs and reduce risks. This research uses the "Rational method" for product design, excluding the "Perceptual method" black box design process, and transforms the "black box" design into the "Transparent box" design, making the design process transparent and reasonable, and the design results are productive and commercial produce. In this article, we use welfare vehicle drivers and wheelchair users to feedback on the use of " Wheelchair Tiedown and Occupant Restraint Systems " (WTORS), using observation methods and researchers' actual operation methods to find product problems, and applying "Objectives tree" Set design goals, perform product design analysis with "morphology chart method", use "DFA" design methods for detailed product mechanical design, and use the "DFA" concept to reduce the number of parts, optimize part design, component interference, assembly analysis, To enhance product quality and assembly solution. This research integrates the synchronous design method to quickly combine the design of the "Wheelchair Tiedown and Occupant Restraint Systems" to achieve the design goals of product safety, fast operation, and reasonable price.

Keyphrases: DFA, Morphology Chart Method, Objectives Tree, WTORS, Welcab vehicle
