Begun in 2008, one of the more fascinating developments in the history of the automotive tyre is the modern concept of the airless tyre. Airless tyres have been getting a ton of media attention recently with Michelin's "Tweel" being praised as the most amazing bit of tyre technology since the invention of the radial tyre. According to a recent market analysis, airless tyre manufacturers are still rated low in terms of functional innovation, mainly focusing their effort on the shape and appearance of the frame. The existing airless tyre has difficulty modifying after it has been manufactured, as well as its lack of adaptability. This project presents the new concept of modular airless tyre developed using Kano, Quality Function Deployment (QFD), and Function Analysis System Technique (FAST) method. Functional analysis is used to identify and analyse interactions of airless tyre components. The user requirements are gathered, analysed using Kawakita Jiro (KJ)/ affinity method for hierarchical analysis and clustered according to the Kano model, and the importance of each group is determined. Then, the function of the MAT body is decomposed using FAST method to obtain the function structure. Finally, the function structure of the MAT is imported into the "requirement-function" of the quality house model to establish the correlation between user requirements and MAT function, and a function system diagram is created. The lack of adjustability of airless tyre is attributed to insufficient interaction between the spoke, hub, and outer ring. The outcome of the experimental design study shows that the proposed function-combining design method allows the designer to effectively grasp real user requirements including safety, simplicity, segmentation, ease of maintenance and reliability are refined into specific solution strategies that are used to generate three new innovative conceptual sketches. Then, design a MAT using a streamlined design process, thus resulting in better designs that meet user expectations. The result shows that concept 2 are the final optimized design based on identified basic function and function were ranked according to importance level.
