Effective design of truck drivers' occupational clothing during public health emergencies based on the Kano-QFD model: experience from China.

Objectives. This study proposes an effective design method for truck drivers' occupational clothing during public health emergencies, reducing development time and costs, optimizing design resource allocation and enhancing truck drivers' occupational safety and mobility experience. Methods. User journey mapping and questionnaires were employed to obtain design requirements for truck drivers' occupational clothing during public health emergencies. The Kano model was utilized to classify user needs and assign importance weights, while a design system was constructed based on the quality function deployment (QFD) method. A prototype of truck drivers' occupational clothing for public health emergencies was developed, and the effectiveness of the design method was validated using fuzzy comprehensive evaluation. Results. The truck drivers' occupational clothing designed based on the proposed system received a satisfactory rating in the fuzzy comprehensive comparative evaluation, scoring 3.491. This rating surpassed two control group driver uniforms, with overall scores of 28.16 and 30.99% higher, respectively. Conclusion. This study presents an effective design method that provides a theoretical reference for the design and iteration of truck drivers' clothing during public health emergencies.
