Abstract: With the huge variables ushering in the Chinese takeaway market “COVID-19 pandemic”, there are more sinking user markets that continue to flood into it and the takeaway industry is booming. After the epidemic, the meaning of the word "takeaway" was extended from catering to food delivery, medicine delivery, and all kinds of necessities, and the takeaway delivery gradually accompanied the new retail consumption habits developed by users during the epidemic. In the whole service system of take-out delivery, with the increasing number of take-out delivery personnel, the take-out delivery e-bikes used are still ordinary travel e-bikes, lacking consideration and design of user behavior and usage scenarios. In the context of the new national standard "electric bicycle safety technical specifications" policy, there are still many takeaway delivery using electric bicycles do not meet the specifications, due to the delivery of limited time to arrive, a one-time delivery of overloaded goods and other cases of traffic accidents caused by frequent. This study introduces the KANO model and hierarchical analysis and TRIZ theory to study the real needs of users, and seeks to conduct innovative design research on take-away delivery electric bicycles.In the preliminary stage of the study, the secondary data research method was used to conduct preliminary summary research on a variety of businesses extending from the take-out industry, and the delivery process of riders in the take-out industry service system after receiving orders was derived through observation, interview, focus group discussion, and questionnaire research methods. Based on the KANO model framework to classify and prioritize user requirements, the non-linear relationship between product features and user satisfaction is identified based on the analysis of the impact of user requirements on user satisfaction. Recognize product and service requirements from the user's perspective, design and publish a valid questionnaire, summarize and classify the survey results, and build a quality model. Further research and analysis of the quality model to identify the sensitivity of specific measurement indicators. Combined with the hierarchical analysis method, the elements within the same level are compared in two-by-two analysis to determine their respective weights for the previous level, and finally give the importance ranking of all factors relative to the total goal, and finally tap into the real user needs. The TRIZ theory is then used to provide systematic theoretical and methodological tools for problem transformation, analysis and solution of needs creatively using innovative thinking methods and problem analysis methods, following the laws of technological system evolution. The KANO model and hierarchical analysis method are effectively combined with TRIZ theory to gradually quantify the qualitative analysis, which can generate more objective research data conclusions and provide innovative ideas for the design research of electric bicycle for delivery.In this study, the different needs of users are organized and differentiated in a hierarchical manner through KANO model analysis, combined with different emotional hierarchical need points of users. Predict the direction of users' emotional needs for the product, and match their emotional requirements with the product at different levels. Combined with the interview research, the design study was conducted taking into account the human-machine factors for the take-away delivery electric bicycle. In line with the new national standard policy, the delivery time of the rider is guaranteed at the same time, the area of the delivery goods and pick-up efficiency is improved, and the riding experience and safety of the rider are also taken into account. This is a research exploration of the takeaway delivery industry.This study combines the KANO model, hierarchical analysis and TRIZ theory to design a study on the process of users for take-out delivery. Through an in-depth study of user behavior, combined with the quantitative study of hierarchical analysis, different levels of demand are derived. Then, through TRIZ theory and emotional design, the take-out delivery service system was optimized and the innovative design of the take-out delivery bicycle was studied. In this study, based on the KANO model approach, the visual experience is designed from the appearance and user experience, giving the electric bicycle emotional factors to form a design that meets the user's needs. The whole design process also explored the correlation between design emotional needs and design form. The design solution evaluation results verified the effectiveness and feasibility of the KANO model approach to user needs analysis in product design and provided an effective solution for the design innovation of electric bicycle for take-away delivery.
