Solution Overview
Problem
Conventional vacuum cleaners fail to effectively remove waste and stains firmly attached to the ground, and the water channel in cleaning equipment often gets blocked by trash from the cleaning roller, leading to inefficiencies in the cleaning process.
Innovation Solution
A water channel assembly with a filtering piece and a seal element, along with a water-squeezing member, is integrated into the cleaning equipment to prevent trash from entering the water channel, ensuring effective filtration and preventing blockages, while the seal element and water-squeezing member are designed to form a seal fitting with the sponge roller to enhance sealing and water extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a water channel is provided to wash the cleaning roller, then the cleaning roller can be washed completely, but trash on the cleaning roller enters the water channel and blocks the waterway
Solution Approach 1:
The water channel is segmented into distinct functional zones: a washing area for cleaning the roller, a filtering area with a filtering piece to intercept trash, and a wastewater discharge area. This segmentation allows water to flow through different stages, separating the cleaning function from the waste removal function, thereby preventing trash from blocking the waterway while maintaining cleaning efficiency.
Solution Approach 2:
A filtering piece is introduced as an intermediary element between the cleaning roller and the water supply system. This filtering piece acts as a mediator that allows water to pass through for washing the roller while intercepting and retaining trash, preventing it from entering and blocking the waterway. The seal element and water-squeezing member further enhance this intermediary function by ensuring proper contact and filtration.
2Reliability
If a filtering piece is added to prevent trash blockage, then the waterway remains clear, but the device complexity increases
Solution Approach 1:
The filtering piece, seal element, and water-squeezing member are merged into a single integrated assembly that fits within the water channel structure. This combination allows multiple functions (filtration, sealing, and water squeezing) to be achieved without adding separate complex components, thereby maintaining structural simplicity while ensuring reliable trash prevention.
Solution Approach 2:
The filtering piece serves multiple functions simultaneously: it filters trash from the water flow, provides a sealing surface for the seal element, and works with the water-squeezing member to extract water from the cleaning roller. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure while maintaining reliability.
3Reliability
If the water channel is sealed tightly to prevent trash leakage, then trash cannot escape, but water flow is restricted
Solution Approach 1:
The seal element is designed with local quality variations: it provides tight sealing at the interfaces where trash containment is critical, while maintaining open passages and adequate gaps in areas where water flow is needed. This localized sealing approach ensures trash containment without unnecessarily restricting water flow through the washing and filtration areas.
Solution Approach 2:
The water-squeezing member is designed to dynamically adjust the sealing pressure and gap size during operation. As the cleaning roller rotates and water flows through the system, the squeezing member adapts its contact pressure to maintain effective trash containment while allowing sufficient water flow. This dynamic adjustment prevents static over-sealing that would restrict water flow.
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 effectively filters out solid trash from the cleaning roller, preventing blockages in the water supply system and ensuring a complete wash of the cleaning roller, thereby improving the cleaning efficiency and maintaining the flow of water.
Implementation Method 1
the filtering piece is laid in the water channel and faces the surface of the cleaning roller
Implementation Method 2
a contact part of the seal element and the surface of the sponge roller is a bulge made of elastic material

AI summary
A water container structure and floor cleaner. The water container structure comprises a water container (351) and filtering member. The water container (351) is sealed and fastened to a surface of a cleaning roller upside down, and is configured to contain clean water to wash the cleaning roller. The filtering member is spread and disposed corresponding to the surface of the cleaning roller and in the water container (351), and therefore, solid waste on the cleaning roller is kept out of the filtering member from entering the water container (351), thereby preventing the waste from causing blockage of a water channel in a water supply system.
