To improve the functional integration, scenario adaptability, and modular coordination of rescue vehicles for hazardous chemical road accidents, this study develops a modular design method integrating the Fuzzy Analytic Hierarchy Process(FAHP), Fuzzy Quality Function Deployment(FQFD), and the Theory of Inventive Problem Solving(TRIZ). First, the emergency rescue process for hazardous chemical road transportation accidents was analyzed, and a hierarchical demand system with 9 primary indicators and 21 secondary indicators was established. Expert judgments were represented by triangular fuzzy numbers, and FAHP was used to calculate the weights of demand indicators. The results show that rapid response capability(0.182), accident-disposal effectiveness(0.160), and personnel safety guarantee(0.158) are the three highest-weighted user demands. Second, FQFD was used to translate weighted demands into technical characteristics. The 21 technical-characteristic modules obtained from preliminary mapping were further refined into 32 evaluation-level characteristics in the House of Quality, allowing comprehensive modules to be decomposed into measurable and configurable design elements. A relationship matrix between the 21 secondary demands and the 32 evaluation-level characteristics was then constructed by 10 engineering experts. The FQFD results indicate that the integrated communication module(0.122), integrated detection module(0.087), and energy power support module(0.077) should be prioritized in design optimization. Third, correlations and key conflicts among technical characteristics were identified through the House of Quality, mapped into TRIZ engineering parameters, and reorganized into seven core design contradictions to derive corresponding inventive principles and implementation strategies. Based on these results, the 32 evaluation-level characteristics were integrated into five functional units: rapid response, core disposal, intelligent support, survival support, and human-machine interaction. The final design achieves a 28% reduction in overall vehicle weight, module switching within 5 min, leak response and disposal within 45 s, a comprehensive driving range of at least 800 km, and a gradeability of 45%. It also defines a Class Ⅲ blast-resistant protection target and reserves interfaces for multi-robot collaborative operation, providing methodological support for the standardization and intelligent upgrading of hazardous chemical rescue equipment.
