Increasing the range of EVs: a TRIZ-inspired approach

This study explores the application of theory of inventive problem solving (TRIZ) methodologies to enhance the driving range of electric vehicles (EVs) without compromising efficiency or weight. The research identifies two primary technical contradictions related to battery capacity and vehicle weight, proposing five ideal final results (IFRs) to resolve these challenges. The solutions include modular battery systems, integrated heat pumps, phase change materials (PCMs) for thermal management, air-drying membranes in heating, ventilation, and air conditioning (HVAC) systems, and piezoelectric misting for energy-efficient cooling. Through systematic use of TRIZ tools such as contradiction matrix, substance-field (Su-Field) analysis, and the smart little people (SLP) method, the study evaluates each solution based on manufacturability, adaptability, cost-effectiveness, and patentability. The results indicate that TRIZ-based approaches offer innovative pathways to increase EV range, reduce energy consumption, and improve overall sustainability. The proposed solutions highlight the potential for integrating advanced technologies into EV design, presenting novel approaches to solving the complex problem of range extension in electric vehicles.
