Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet/dry vacuum cleaners are bulky and inconvenient due to the arrangement of the cleaning fluid box and dirt box on the device body, leading to space inefficiency and difficulty in operating in confined spaces.
Innovation Solution
A cleaning device with a detachable handheld vacuum and a sewage storage box that includes a partition plate with an anti-backflow structure, allowing for independent use of components and preventing sewage from flowing into the motor, combined with a cyclone filter assembly for effective dust-gas separation, and a compact floor brush design with a magnetic suction structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning fluid box and dirt box are arranged on the device body, then the vacuum cleaner can perform wet/dry cleaning functions, but the vacuum cleaner becomes bulky and space-consuming
Solution Approach 1:
The vacuum cleaner is divided into separate functional modules: a handheld vacuum cleaner unit and a detachable sewage storage box. This segmentation allows the main body to remain compact while the storage box can be attached only when wet/dry cleaning is needed, resolving the contradiction between functionality and size.
Solution Approach 2:
The sewage storage box is designed to be detachably connected to the handheld vacuum cleaner, allowing the system configuration to change dynamically based on cleaning needs. When not in use, the box can be removed, making the device compact and easy to store.
2Adaptability or versatility
If the handheld vacuum cleaner and sewage storage box are integrated, then multiple functions are achieved, but the load weight increases making operation inconvenient
Solution Approach 1:
The system is segmented into a lightweight handheld vacuum cleaner and a separate sewage storage box. Users only carry the essential motor unit during dry vacuuming, and the heavier storage box is attached only when wet/dry cleaning is required, effectively managing weight based on operational needs.
Solution Approach 2:
The handheld vacuum cleaner unit is designed as a universal base that can operate independently for dry vacuuming or be combined with the sewage storage box for wet/dry cleaning, allowing the core component to serve multiple functions without permanently increasing weight.
3Device complexity
If the sewage storage box lacks anti-backflow structure, then the structure is simpler, but sewage can flow into the motor causing it to stop
Solution Approach 1:
An anti-backflow structure is introduced as an intermediary component between the sewage storage box and the handheld vacuum cleaner. This structure acts as a protective barrier that prevents sewage from flowing back into the motor, ensuring reliable operation without significantly complicating the overall design.
4Device complexity
If the cyclone filter assembly is not properly positioned, then the structure is simpler, but mixed liquid can enter the air inlet causing motor damage
Solution Approach 1:
The cyclone filter assembly serves as an intermediary separation device positioned between the sewage inlet and air inlet. It uses centrifugal force to separate mixed liquid from air, preventing liquid from reaching the motor while maintaining a relatively simple structural configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a lightweight, compact, and versatile cleaning device that can perform floor vacuuming, handheld vacuuming, and wet/dry cleaning efficiently, preventing motor damage and ensuring continuous operation in various scenarios.
Implementation Method 1
the cyclone filter assembly communicates with an interior of the box body, the cyclone filter assembly includes the air inlet, the fluid entering from the sewage pipe is separated into the mixed gas and the mixed liquid at the sewage outlet, the mixed gas enters the cyclone filter assembly through the air inlet for cyclone dust-gas separation

AI summary
The embodiments of the present disclosure provide a cleaning device, the cleaning device including a body and a floor brush. The floor brush is connected to one end of the device body; the device body is provided with a sewage storage box, and the box body of the sewage storage box is at least for storing and/or filtering garbage suctioned by the floor brush. When the cleaning device is tilted or laid flat for use, no sewage may flow back into the motor from the sewage storage box, which prevents causing the motor to stop or be damaged, and ensures a normal use of the cleaning device.
