Removable Cleaner Module Structure for Dust-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners require manual disassembly, which poses sanitary issues as users must touch accumulated dust during maintenance, and do not allow for easy replacement or automatic recognition of cleaning modules.
Innovation Solution
A cleaner design featuring a supporting member and cleaning module that can be inserted and withdrawn through the bottom of the cleaner body, with a rotation rod and elastic member for automatic module recognition and easy maintenance, allowing dust-free handling and automatic selection of cleaning algorithms based on module type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If components are made separable for maintenance, then ease of repair is improved, but user sanitation deteriorates because users must touch dust accumulated in the cleaner
Solution Approach 1:
The dust collection bag serves as an intermediary element that isolates dust from the user during component separation. Users remove the dust collection bag first, which contains all accumulated dust, before handling other components. This mediator approach allows easy component separation while preventing direct user contact with dust.
Solution Approach 2:
The cleaner is segmented into distinct modules: dust collection bag, brush assembly, mop assembly, and cleaner body. This segmentation allows users to remove and handle only the clean components (brush assembly, mop assembly) separately from the dust-containing bag, maintaining sanitation while enabling easy maintenance and component replacement.
2Adaptability or versatility
If cleaning modules are made replaceable, then adaptability is improved, but device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The coupling mechanism between the dust collection bag and cleaner body performs multiple functions: it securely holds the bag during operation, allows easy user removal, and enables automatic recognition of module presence. This universal coupling design achieves cleaning module replaceability without requiring separate complex mechanisms for each function.
Solution Approach 2:
The coupling mechanism integrates physical connection, security locking, and electrical recognition functions into a single unified structure. The coupling member includes both mechanical coupling elements and electrical contact elements, merging multiple functions to reduce overall device complexity while maintaining adaptability.
3Productivity
If automatic module recognition is implemented, then productivity is improved through automated cleaning algorithm selection, but device complexity increases due to recognition systems
Solution Approach 1:
The cleaner automatically recognizes which cleaning module is installed and self-configures the appropriate cleaning algorithm without user intervention. The recognition system automatically detects module presence and type, then the controller autonomously selects and executes the corresponding cleaning program, achieving productivity improvement with minimal added complexity.
Solution Approach 2:
The coupling mechanism includes electrical contact elements that provide feedback signals to the controller about module presence and type. This simple feedback system enables automatic recognition by transmitting basic identification information from the module to the controller, which then automatically adjusts cleaning parameters without requiring complex recognition hardware.

AI summary
Disclosed is a cleaner having a structure that a supporting member and a cleaning module are coupled to or separated from a cleaner body. The cleaner includes a cleaner body having a module mounting portion; a supporting member inserted and mounted to the module mounting portion, and separated and withdrawn from the module mounting portion, through a bottom part of the cleaner body; and a cleaning module coupled to the supporting member so as to be inserted or withdrawn together with the supporting member when the supporting member is inserted or withdrawn.
