Pipeline Connector Sleeve With Haptic Insertion Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline connection devices fail to reliably ensure correct insertion due to reliance on insertion force and noise-based feedback, leading to potential leaks and system failures, especially in noisy environments or poor lighting conditions.
Innovation Solution
Incorporation of radially elastic tabs on the support sleeve with sensor elements that generate distinct haptic signals based on insertion depth, providing a second haptic feedback to ensure correct insertion, and an electronic resistance profile evaluation for automated checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic signals are used to signal correct insertion depth, then insertion verification is provided, but the signal is hardly perceptible in noisy environments and requires large space within the connection body
Solution Approach 1:
The patent replaces the acoustic signal system with a haptic feedback system using radially elastic tabs that generate tactile resistance changes. When the pipeline reaches correct insertion depth, the tabs deform radially outward, creating a distinguishable haptic signal that is independent of acoustic noise and requires minimal space within the connection body.
2Reliability
If colored markings are applied to indicate insertion depth, then visual feedback is provided, but the markings cannot be verified in poor lighting conditions or hidden installation positions
Solution Approach 1:
The patent replaces visual color markings with a haptic feedback mechanism using radially elastic tabs. The tactile resistance change generated when the pipeline reaches correct insertion depth can be perceived through touch alone, making verification possible in poor lighting conditions or hidden installation positions where visual inspection is not feasible.
3Ease of operation
If insertion force alone determines correct insertion, then the system is simple to operate, but incorrect insertion occurs when user does not exert necessary force or misinterprets resistance
Solution Approach 1:
The patent introduces haptic feedback through radially elastic tabs that generate distinct tactile resistance changes at correct insertion depth. This feedback mechanism guides the user through the insertion process, providing clear sensory confirmation when the pipeline is correctly positioned, thereby preventing misinterpretation of resistance and ensuring reliable insertion accuracy while maintaining operational simplicity.

AI summary
The present invention relates to a connection device (1) for pipelines (2) with a connection body (4) having a receiving opening for a pipeline (2) to be inserted with a line end (2a) in an insertion direction (E). Within the receiving opening, a support sleeve (6) is arranged coaxially such that the line end (2a) can be pushed onto a cylindrical outer surface (6a) of the support sleeve (6) by means of an assembly force during insertion, and a retaining element (5) for fixing the inserted line end against being pulled out is mounted within the receiving opening. Within the connection body, at least one circumferential seal (8) is arranged which seals an annular gap formed radially between the line end (2a) and the connection body (4) to the outside, wherein the circumferential seal (8) generates a haptic signal in the form of a sudden increase in insertion resistance when the line end (2a) comes into contact with the circumferential seal.The support sleeve (6) has at least one sensor element (10) which generates a second haptic signal in the form of a sudden increase in the insertion resistance depending on the insertion depth of the cable end (2a) in the insertion direction (E) behind the circumferential seal (8) within the connection body (4).
