Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the cleaning liquid is continuously used for wiping the nozzle face, then the wiping operation can be maintained, but the cleaning liquid becomes contaminated and loses effectiveness over time
Solution Approach 1:
The system recovers the cleaning liquid after use by collecting it from the wiping device, filtering out contaminants, and recycling it back to the cleaning liquid tank. This allows the cleaning liquid to be reused multiple times while maintaining its effectiveness, resolving the contradiction between extended usage duration and reliable cleaning performance.
Solution Approach 2:
The cleaning liquid circulation system implements a feedback mechanism where the state of the cleaning liquid is monitored through filtration, and the system automatically adjusts by filtering and recycling the liquid to maintain optimal cleaning performance throughout extended operation periods.
2Reliability
If a large amount of cleaning liquid is used, then the cleaning performance is maintained, but the volume of liquid to be managed increases and waste increases
Solution Approach 1:
Instead of discarding used cleaning liquid, the system recovers and recycles it through filtration. This eliminates waste while maintaining cleaning performance, as the same cleaning liquid is reused multiple times after removing contaminants.
Solution Approach 2:
The cleaning liquid circulation system enables continuous reuse of the same cleaning liquid volume by constantly filtering and recycling it. This maintains cleaning performance over extended periods without increasing liquid consumption or waste.
3Device complexity
If the cleaning liquid is not circulated and filtered, then the system structure remains simple, but foreign substances accumulate and reduce cleaning effectiveness
Solution Approach 1:
The circulation and filtration system creates a feedback loop where cleaning liquid is continuously monitored for contamination and automatically filtered when needed. This maintains cleaning effectiveness while keeping the system relatively simple through automated operation.
Solution Approach 2:
The cleaning liquid circulation system is designed to operate automatically without manual intervention. The pump circulates the liquid and the filter automatically removes contaminants, allowing the system to maintain itself and preserve cleaning effectiveness without complex manual management procedures.
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 ensures the cleaning liquid remains effective by filtering out foreign substances, preventing contamination and maintaining the cleaning performance of the wiping web, thus extending the cleaning efficiency and reducing maintenance needs.
Implementation Method 1
The filter is disposed in the circulation path, to filter the cleaning liquid flowing through the filter
Implementation Method 2
The liquid feeder is disposed in the circulation path, to generate a flow of the cleaning liquid circulating through the circulation path

AI summary
A wiping device includes a cleaning liquid tank, an endless web, a circulation path, a liquid feeder, and a filter. The cleaning liquid tank stores a cleaning liquid. The endless web is rotatably movable and has a part immersed in the cleaning liquid in the cleaning liquid tank and another part outside the cleaning liquid to wipe an object in a wiping direction. The cleaning liquid is circulated through the circulation path. The liquid feeder is disposed in the circulation path, to generate a flow of the cleaning liquid circulating through the circulation path. The filter is disposed in the circulation path, to filter the cleaning liquid flowing through the filter.
