Blocking plug and intelligent cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cleaning devices, such as sweeping robots, suffer from water leakage issues at the water outlet due to poor sealing and inconvenient mounting of the water tank.
Innovation Solution
A blockage mechanism comprising a shaft-shaped plug body with a through hole and a hierarchical sealing structure, featuring stacked annular plugs with varying diameters and thicknesses, is designed to prevent liquid leakage and facilitate easy mounting and removal of the water tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple plug structure is used for the water outlet, then the device complexity is reduced, but the sealing effect deteriorates causing water leakage
Solution Approach 1:
The plug body is divided into multiple functional segments: a shaft-shaped main body for basic blocking, a hierarchical sealing structure with multiple annular plugs for enhanced sealing, and a retaining wall system for positioning. This segmentation allows each component to specialize in its function while working together to resolve the contradiction between simplicity and sealing effectiveness.
Solution Approach 2:
The hierarchical sealing structure employs nested annular plugs where smaller diameter annular plugs are positioned within or adjacent to larger diameter ones, creating multiple sealing layers. This nested arrangement provides progressive sealing without requiring a completely complex plug design, thus improving sealing while maintaining reasonable device complexity.
2Reliability
If a complex sealing structure is used for the water outlet, then the sealing effect is improved, but the mounting convenience deteriorates
Solution Approach 1:
The hierarchical sealing structure and retaining walls are pre-integrated into the plug body as a single assembled unit during manufacturing. This preliminary assembly means that during actual mounting, the user installs the complete plug assembly in one action without needing to separately position multiple sealing components, thereby maintaining mounting convenience despite the complex sealing structure.
Solution Approach 2:
The retaining walls act as intermediary elements that facilitate the mounting process. These walls provide mechanical guidance and positioning features that enable the complex hierarchical sealing structure to be installed easily by providing natural alignment and engagement points, thus mediating between structural complexity and mounting simplicity.
3Reliability
If the plug body is made with multiple components for better sealing, then the sealing effect is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple sealing components including the shaft-shaped plug body, hierarchical annular plugs, and retaining walls are combined into a single integrated plug assembly. This merging approach consolidates multiple manufacturing operations into one unified component or pre-assembled unit, reducing the overall manufacturing complexity despite the enhanced sealing functionality.
Solution Approach 2:
The plug body structure is designed to serve multiple functions simultaneously: the shaft-shaped body provides structural support and blocking function, the hierarchical annular plugs provide progressive sealing, and the retaining walls provide positioning and mounting assistance. This multi-functionality reduces the need for separate specialized components, thereby simplifying manufacturing while achieving superior sealing.
