Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treatment apparatus filters become clogged with impurities such as lint, requiring manual cleaning, which is time-consuming and inefficient.
Innovation Solution
A filter cleaning device with a driving mechanism and spraying mechanism that sprays a cleaning fluid onto the filter, moving in multiple directions and angles to cover at least 80% of the filtration area, using a water supply pipe and spray head with spaced holes, and controlled by a control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual cleaning of the filter is required, then the filter can be cleaned, but it consumes user time and effort and is not intelligent
Solution Approach 1:
The filter cleaning device enables the filter to clean itself automatically through a spraying mechanism that delivers cleaning fluid to the filter surface, eliminating the need for manual disassembly and cleaning by the user. The system performs self-maintenance functions autonomously.
Solution Approach 2:
The patent replaces manual mechanical cleaning operations with an automated spraying mechanism that uses fluid dynamics to clean the filter. The spraying mechanism substitutes human hand operations with automated fluid-based cleaning.
2Area of stationary object
If the spraying mechanism covers a large area of the filter, then cleaning comprehensiveness is improved, but the complexity of the driving mechanism increases
Solution Approach 1:
The patent employs multi-directional movement (horizontal, vertical, and rotational dimensions) of the spraying mechanism to achieve comprehensive filter coverage. By adding rotational movement around the filter circumference and vertical movement along the filter height, the system covers the entire filter surface area effectively.
Solution Approach 2:
The spraying mechanism incorporates dynamic multi-axis movement capabilities, allowing it to adapt its position and orientation to cover different areas of the filter. The mechanism transitions between horizontal scanning, vertical scanning, and rotational movements to systematically clean the entire filter surface.
