Abstract: With the growing user base of washing machines, personalized home appliances are also increasing. To enhance space utilization and aesthetic appeal, designers innovatively installed clothing care devices in countertop form, meaning the washing machine is mounted on kitchen counters or in confined spaces. This design not only saves space but also integrates seamlessly with the kitchen or balcony environment, improving overall aesthetics. However, due to the limited installation space for clothing care devices, the requirements for displacement caused by eccentricity are higher. When the device experiences significant displacement due to eccentricity, it may collide with surrounding objects or even fall off the countertop, increasing operational safety risks. Therefore, anti-fall technology is proposed for small washing machines. By analyzing the relationship between acceleration squared data and displacement, the risk of machine movement is predicted in advance, achieving a detection rate of over 94%. This method is reliable and enhances user experience.
