Automatic water changing assembly and self-cleaning maintenance station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cleaning devices require manual replenishment of clean water and sewage disposal, which is inconvenient and reduces cleaning efficiency due to separate water tank designs.
Innovation Solution
An automatic water replacement assembly with a control apparatus and integrated water tank assembly, allowing for automatic replenishment of clean water and sewage discharge within a self-cleaning maintenance station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual water replenishment and sewage removal are used, then device complexity is reduced, but productivity decreases due to frequent manual intervention
Solution Approach 1:
The patent combines the clean water tank and sewage tank into a single integrated water tank assembly with a unified bottom shell and top shell structure. This merging eliminates the need for separate manual intervention systems while maintaining automated water replenishment and sewage removal functions, thereby improving productivity without proportionally increasing device complexity
Solution Approach 2:
The water tank assembly incorporates automatic water replenishment through a water inlet valve that opens when the water level sensor detects low water levels, and automatic sewage removal through a drainage pump that activates when the sewage level sensor detects high sewage levels. This self-service mechanism eliminates manual intervention, significantly improving cleaning efficiency
2Ease of operation
If separate water tank design is used, then ease of operation is reduced, but device complexity is lowered
Solution Approach 1:
The patent integrates the clean water tank and sewage tank into a single assembled unit with shared top shell and bottom shell components. This merged design allows the water tank assembly to be installed as one complete unit, greatly improving ease of operation compared to installing separate tanks individually
Solution Approach 2:
The water tank assembly is designed with modular segmentation, allowing it to be disassembled into top shell, bottom shell, and tank body components for convenient transportation and installation. This segmentation maintains ease of operation while managing the complexity of the integrated structure
3Productivity
If automatic water replenishment system is added, then productivity improves, but device complexity increases
Solution Approach 1:
The system uses a water level sensor that automatically detects when water needs replenishment and triggers the water inlet valve to open. This self-service automation improves productivity by eliminating manual water checking and replenishment, while the simplicity of the sensor- valve connection keeps control system complexity manageable
Solution Approach 2:
The water level sensor provides continuous feedback to the control system about the water level status, enabling automatic activation of the water inlet valve when water is low. This feedback mechanism improves water replenishment efficiency while maintaining relatively simple control logic
4Ease of operation
If integrated water tank assembly is used, then ease of operation improves, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple tank functions into a single assembled structure with shared top shell and bottom shell, improving ease of operation by reducing the number of components to handle. The manufacturing complexity is managed through standardized connection interfaces and modular assembly steps
Solution Approach 2:
The integrated water tank assembly is designed with separable components (top shell, bottom shell, tank body) that can be manufactured independently and then assembled. This segmentation allows each component to be manufactured using standard processes while the final assembly provides integrated functionality
