The Kaizhilun household cleaning machine adopts modular assembly and detachable styling parts, which solves the problems of homogenization and low brand recognition of traditional products, breaks through the limitations of high mold opening costs and single styling, and meets users' needs for personalization and practicality. It provides replaceable styling parts for personalized choices. The ergonomic handle and compact body enhance usability, while the yellow warning color ensures operational safety. The three-color visual system and special-shaped heat dissipation grille combine aesthetics with functionality. In addition, the yellow super symbol strengthens the recognition of the brand's "K" element. The modular design achieves "diversification with one set of molds", integrating aesthetics and practical functions, reflecting a systematic and complete design concept.
