Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothes treating apparatuses face issues with air flow interference due to excessive foreign materials collected in filters during the drying process, requiring regular filter cleaning and potential uncontrolled discharge of high-temperature, high-humidity air.
Innovation Solution
A clothes treating apparatus equipped with a filter assembly and a filter insertion detecting device, such as an electrode sensor, switch, or reed switch, that detects the insertion and removal of the filter assembly, ensuring efficient air flow management and automatic detection of filter status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter assembly is used to collect foreign materials during the drying process, then air flow is initially maintained, but foreign materials accumulate and interfere with air flow over time
Solution Approach 1:
The system performs preliminary detection of filter insertion status before the drying process begins. The detecting device checks whether the filter assembly is properly installed, and the control unit prevents the drying process from starting if the filter is not correctly positioned, ensuring air flow continuity from the outset
2Reliability
If the filter assembly is regularly cleaned by user intervention, then foreign material accumulation is prevented, but operational complexity and time loss increase
Solution Approach 1:
The detecting device continuously monitors the filter assembly status and provides feedback to the control unit. When the filter is removed or not properly installed, the system generates a notification signal to alert the user, enabling timely maintenance while reducing the need for continuous user monitoring
Solution Approach 2:
The system automatically detects and monitors filter assembly status without requiring user intervention. The detecting device and control unit work together to self-monitor the filter position, reducing the burden on users while maintaining reliable operation
3Object-affected harmful factors
If the filter assembly is not properly detected, then uncontrolled discharge of high-temperature air may occur, but adding detection devices increases device complexity
Solution Approach 1:
The system uses an electrode sensor that detects the filter assembly through electrical contact or proximity sensing, replacing more complex mechanical detection mechanisms. This provides reliable detection of filter status while maintaining relatively simple device structure
Solution Approach 2:
The detecting device serves multiple functions: it detects filter insertion status, triggers process control decisions, and generates user notifications. This multi-functionality reduces the need for separate detection and control components, simplifying the overall device structure
