Ribbed Hose Coupling Piece for Visible Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling systems for ribbed hoses and channel parts in air ventilation, heating, and cooling systems often result in false air leaks due to inadequate sealing and the risk of misalignment during installation, making it difficult to achieve a secure and airtight connection.
Innovation Solution
A coupling system comprising a coupling piece with a first and second shape-retaining part and a resilient part, where the resilient part forms a seal between the hose and channel part, allowing for visual confirmation of proper alignment and secure fixation, preventing detachment under tension, and optionally featuring air flow guides and restriction members for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a seal is placed inside the channel part, then the coupling can be made simply, but the seal cannot be visually confirmed and may become displaced during installation
Solution Approach 1:
The coupling piece acts as an intermediary component between the hose and channel part. It includes a resilient part that forms a seal between the hose and the coupling piece, and another resilient part that forms a seal between the coupling piece and the channel part. This intermediary structure allows the seal to be visually confirmed during installation while maintaining simplicity of coupling.
Solution Approach 2:
The sealing function is segmented into two separate sealing interfaces: one between the hose and coupling piece, and another between the coupling piece and channel part. This segmentation allows each seal to be independently positioned and visually confirmed, eliminating the problem of unobservable seals while maintaining installation simplicity.
2Productivity
If the hose is placed directly in the channel part, then the coupling process is simple, but false air can pass along the coupling if the hose is not placed sufficiently far in
Solution Approach 1:
The coupling piece is pre-positioned on the hose with its sealing parts already in place before the hose is inserted into the channel part. This preliminary arrangement of sealing components ensures that proper sealing is achieved automatically during the coupling process, maintaining high productivity while ensuring reliability.
Solution Approach 2:
The coupling piece serves as a mediator that guides the hose into the correct position within the channel part. The resilient sealing parts on the coupling piece ensure proper engagement and sealing, preventing false air passage while maintaining a simple and fast coupling process.
3Device complexity
If the seal is located inside the channel part, then the structure is compact, but the seal cannot be seen to confirm proper alignment and may detach under tension
Solution Approach 1:
The sealing function is divided into two separate locations: one seal between the hose and coupling piece (visible during installation), and another seal between the coupling piece and channel part. This segmentation maintains structural compactness while enabling visual confirmation of proper sealing alignment.
Solution Approach 2:
The coupling piece acts as an intermediary that houses visible sealing components. The resilient parts on the coupling piece can be seen during installation to confirm proper alignment, while the overall structure remains compact. The coupling piece also provides mechanical support to prevent seal detachment under tension.

AI summary
The invention relates to an air ventilation, heating and cooling system provided with a coupling system. The coupling system comprises a ribbed hose (20), a channel part (3) and a coupling piece (1) for coupling the ribbed hose to the channel part. The channel part is configured for placing at least a portion of the coupling piece in the channel part. The coupling piece has an opening for placing the ribbed hose, the coupling piece having a first shape-retaining part (4) and a second shape-retaining part (6) with a resilient part (5) therebetween. The first shape-retaining part and the resilient part are configured to grant the ribbed hose access into the second shape-retaining part. The resilient part is configured to form a seal between the ribbed hose and the channel part.
