Dehumidifier Sealing Plug Assembly for Reliable Drainage Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifiers face issues with the reliability and convenience of the sealing plug assembly, which can detach due to external forces, affecting the sealing performance and drainage efficiency.
Innovation Solution
The dehumidifier design includes a fixing structure and a sealing plug assembly with a connecting member and protruding ribs, which enhances the connection between the sealing plug assembly and the drainage pipe, ensuring reliable sealing and easy installation by guiding the sealing plug assembly through an inclined surface and accommodating it in a through hole, thereby preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing plug assembly uses a simple structure without additional fixing components, then the device complexity is reduced, but the sealing plug assembly can detach due to external forces, affecting reliability
Solution Approach 1:
The patent combines the sealing plug assembly with the drainage pipe by integrating a fixing structure directly into the drainage pipe wall. The fixing structure includes a protruding rib that fits into a corresponding groove on the sealing plug assembly, creating a unified component that prevents detachment while maintaining sealing performance.
Solution Approach 2:
The sealing plug assembly is nested within the drainage pipe structure. The connecting member of the sealing plug assembly passes through a through-hole in the drainage pipe, and the protruding rib on the drainage pipe fits into the groove on the sealing plug assembly, creating a nested configuration that secures the sealing plug in place.
2Reliability
If the sealing plug assembly uses a complex fixing structure with multiple components, then the reliability and anti-detachment performance are improved, but the ease of operation for installation and maintenance is reduced
Solution Approach 1:
The fixing structure is segmented into distinct functional elements: a connecting member on the sealing plug assembly, a through-hole in the drainage pipe, and a protruding rib with groove configuration. This segmentation allows each component to perform its specific function while maintaining overall simplicity and ease of assembly.
Solution Approach 2:
Instead of adding complex external fixing mechanisms to prevent detachment, the patent inverts the approach by designing the drainage pipe with an integrated fixing structure (protruding rib) that naturally engages with the sealing plug assembly's groove, making the sealing plug itself part of the fixing mechanism.
3Reliability
If the sealing plug assembly is securely fixed to prevent detachment, then the reliability is improved, but the ease of repair for maintenance and replacement is reduced
Solution Approach 1:
The fixing structure employs a dynamic yet reversible connection mechanism. The protruding rib fits into the groove to provide secure fixation during operation, but the connection can be easily reversed by simply pulling the sealing plug assembly out of the drainage pipe, allowing for quick maintenance and replacement without permanent attachment.
