Floor Cleaner Filter Assembly with Magnetic Installation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget to reinstall or incorrectly reinstall removable components in floor cleaners, such as brushrolls and filters, leading to poor cleaning performance and potential damage to the device, and may replace these components with low-quality alternatives that do not meet the requirements of the floor cleaner.
Innovation Solution
Incorporating a detection mechanism using a magnet and a Hall Effect sensor to ensure that replaceable components, like brushrolls and filters, are correctly installed before allowing the operation of electrically-powered components in the floor cleaner, preventing operation if the components are missing, incorrectly mounted, or of low quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If removable components (brushrolls, filters) are made easily replaceable, then ease of maintenance and cleaning is improved, but risk of incorrect installation or use of low-quality replacements increases
Solution Approach 1:
The patent implements a detection mechanism using magnets embedded in replaceable components and corresponding sensors in the floor cleaner body. When a component is installed, the magnet-sensor interaction provides feedback to confirm proper installation. This feedback system ensures that only correctly installed components allow the device to operate, resolving the contradiction by maintaining ease of replacement while guaranteeing installation correctness.
2Reliability
If detection mechanisms are added to verify component installation, then reliability of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical verification systems with a simplified magnetic detection mechanism. Instead of using mechanical interlocks, switches, or complex sensor arrays, the invention uses simple magnets embedded in replaceable components that interact with corresponding sensors. This substitution dramatically reduces device complexity while maintaining reliable detection of component installation status.
3Object-affected harmful factors
If operation is prevented without proper components, then damage prevention and performance maintenance are improved, but user convenience decreases
Solution Approach 1:
The patent implements preliminary verification through magnetic detection before allowing operation. The system checks for proper component installation in advance by detecting magnet-sensor interactions, and only permits operation when verification is successful. This preliminary action prevents damage and performance issues while maintaining user convenience, as users receive immediate feedback about installation status without needing to remember complex procedures.

Function Achieved in This Case
Ensures proper installation of essential components, preventing damage and maintaining cleaning performance by only allowing the floor cleaner to operate with authorized and correctly mounted parts, thereby enhancing user experience and extending the lifespan of the device.
Implementation Method 1
a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner
Data Source
AI summary
The present disclosure provides a floor cleaner that includes a replaceable component, such as a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.
