Hose Connector Scale Alignment for Precise Seal Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting elements for hoses and pipes struggle with inconsistent contact pressure during screwing, leading to inadequate tightness and potential damage to seals due to manufacturing tolerances and material variations, as well as difficulty in adjusting pressure to account for seal aging.
Innovation Solution
Incorporating a first scale with multiple measurement markings and a second scale with reference markings on opposing connecting parts, allowing precise adjustment of contact pressure by aligning the reference markings during screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If manual or mechanical screwing is used to connect the parts, then the connection can be assembled, but the contact pressure is difficult to adjust and inconsistent
Solution Approach 1:
The patent applies parameter changes by introducing scales with measurement markings that allow the contact pressure parameter to be precisely controlled and adjusted during the screwing process. The scales enable the user to monitor and adjust the twisting degree, thereby controlling the contact pressure applied to the seal.
2Reliability
If higher contact pressure is applied to ensure tightness, then sealing improves, but the seal may break, deform or age prematurely
Solution Approach 1:
The patent implements feedback by providing scales with measurement markings that give real-time visual feedback during the screwing process. This allows the user to monitor the contact pressure being applied and stop at the optimal point, preventing over-compression that would damage the seal while ensuring sufficient compression for tightness.
3Ease of operation
If a single marking alignment method is used, then assembly is simplified, but fine adjustment of contact pressure is not possible
Solution Approach 1:
The patent applies segmentation by dividing the scale into multiple measurement markings instead of using a single marking. This segmentation allows for progressive and precise adjustment of the contact pressure, enabling the user to achieve fine-tuned control over the sealing force while maintaining a systematic assembly process.
4Manufacturing precision
If manufacturing tolerances or material variations occur in the seal, then the contact pressure becomes incorrect, but these variations are unavoidable
Solution Approach 1:
The patent applies preliminary action by providing scales that enable pre-adjustment and monitoring of contact pressure before final tightening. This allows the user to compensate for manufacturing tolerances and material variations in the seal by adjusting the screwing degree to achieve the correct contact pressure, ensuring reliable tightness despite variations in seal dimensions.

AI summary
The invention relates to a connecting element for hoses, pipes or other fluid transportation devices, having at least two connecting parts, wherein the connecting parts can be screwed together about screw axes of the connecting parts, wherein at least one connecting part has at least one receptacle for a seal for sealing the connection between at least two of the connecting parts, wherein a first connecting part has at least one first scale with a plurality of measurement markings and a second connecting part has at least one second scale with at least two reference markings, and wherein the first scale and the second scale are opposite one another in the screwed state and can be rotated relative to one another by turning the screw connection.
