Laundry Drain Hose Venting Clip for Leak-Safe Pump-Out Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suds pumping lines for laundry care appliances are complex and costly to assemble, with known configurations being error-prone and requiring multiple components for ventilation and sealing, leading to inefficient assembly and potential leaks.
Innovation Solution
A suds pumping line featuring a corrugated hose with an integral ventilation device and a one-piece plastic clamp for easy attachment, which includes a latching device and positioning elements for precise alignment, reducing the need for additional components and simplifying assembly, while also providing a compact sealing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex hose holder with multiple O-rings and separate components is used for ventilation and sealing, then sealing reliability is improved, but device complexity and assembly cost increase
Solution Approach 1:
The patent combines the hose holder, ventilation device, and sealing elements into a single integrated component. The hose holder is formed as one piece with the ventilation opening and includes an integrated O-ring seal, eliminating the need for separate connecting pieces and multiple sealing elements. This merging reduces the number of parts while maintaining sealing reliability through the integrated design.
2Adaptability or versatility
If multiple separate components and hose clamps are used for assembly, then adaptability is improved, but ease of manufacture and assembly time worsen
Solution Approach 1:
The patent segments the integrated hose holder into functional zones: a corrugated section for flexibility, a smooth section for connection, and an integrated ventilation device with sealing. This segmentation allows each zone to perform its specific function optimally while the entire component remains a single piece that is easy to manufacture and assemble.
3Reliability
If a return tank with larger cross-section is integrally formed in the hose, then ventilation capacity is improved, but device complexity and assembly precision requirements increase
Solution Approach 1:
The patent implements local quality by providing a smooth outer surface on the hose holder specifically in the region where the ventilation device is formed. This localized smooth surface facilitates easy attachment of the ventilation component without requiring the entire hose to be smooth or complex, thus improving ventilation capacity while maintaining manufacturing simplicity.
