In recent years, the frequent epidemic situation has seriously affected people's healthy life, and more and more attention has been paid to household cleaning. Keeping the household environment clean and hygienic has become the most cured health need in people's hearts; with the continuous strengthening of cleaning concept and the continuous upgrading of robot technology, people have higher requirements for household cleaning, Household cleaning robots that can achieve all-round cleaning are expected to become the necessities of future families.
Firstly, by studying the current situation and connotation of the modular theory, the principles, processes and methods of modular design of household cleaning robots are proposed; secondly, the requirements are obtained through questionnaires and user interviews, and the KANO model and functional requirements questionnaire are used to output the level of household cleaning requirements; then the product category, functional structure, technical principles, use processes and other information of cleaning appliances are obtained through product research, and the modular conditions of cleaning appliances are analyzed; finally, the acquired requirements and functions are matched according to the modular conditions of the product, and the modular design scheme of the household cleaning robot is obtained.
This topic is composed of three parts: theory, research and practice. Through research and analysis, the user needs and product functions are obtained, and the modular design scheme of household cleaning robot is obtained by applying the modular theory to match. The scheme can independently complete the cleaning task of the ground and air, has five modules and three combinations, provides a variety of cleaning schemes, and has the characteristics of diverse functions, intelligence and low cost, it provides a reference for enterprise product iteration, product serialization and new product development.
