Hose-Attaching Apparatus for Simultaneous Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for leak testing hoses are time-consuming and prone to missing leaks, as they require manual scanning with a small test tip, which can be affected by ambient air dilution and operator error, leading to inaccurate results.
Innovation Solution
A hose-attaching apparatus with a bore and internal annular cavity that allows a detector probe to test larger sections of hoses simultaneously, maintaining constant distance and reducing ambient air interference, using a hose-attaching member with a bore and internal annular cavity to accommodate the hose and a detector probe for efficient leak detection.

Engineering Contradiction Analysis
1Ease of operation
If a small test tip is used for leak detection, then the detector can be compact and easy to handle, but the testing time increases substantially and leaks may be missed
Solution Approach 1:
Multiple detector probes are combined into a single detector assembly that can test multiple locations simultaneously. The detector assembly includes several detector probes arranged in a specific configuration, allowing parallel detection at multiple points along the hose, thereby dramatically increasing testing productivity while maintaining ease of operation.
Solution Approach 2:
The detector assembly extends the detection capability from a single-point linear scan to a multi-dimensional testing approach. By arranging detector probes in spatial configuration (e.g., multiple probes at different positions and angles), the system can test larger hose sections simultaneously, transitioning from one-dimensional sequential testing to multi-dimensional parallel testing.
2Device complexity
If a small test tip is used for leak detection, then the detector structure can be simple, but the testing accuracy decreases due to ambient air dilution
Solution Approach 1:
A shroud or housing structure surrounds the detector probes, creating a confined detection zone that prevents ambient air from diluting the sampled gas. This shroud acts as a barrier that directs the leak sample directly to the detector probes while excluding surrounding ambient air, thereby maintaining high measurement precision without significantly increasing overall device complexity.
Solution Approach 2:
Sampling ports and conduits serve as intermediaries between the hose surface and detector probes. These intermediaries channel the leak sample directly to the detection elements while isolating the detection process from ambient air interference, improving measurement accuracy without requiring complex detector structures.
3Ease of operation
If manual scanning with a small test tip is used, then the device can be simple to operate, but operator error increases and readings become inaccurate
Solution Approach 1:
The detector assembly is designed to move systematically along the hose in a controlled manner, either manually guided or automated. This dynamic movement ensures consistent spacing between the detector probes and the hose surface, maintaining optimal detection conditions throughout the testing process and eliminating operator error related to inconsistent positioning.
Solution Approach 2:
The system incorporates real-time feedback mechanisms that monitor the position of the detector assembly and adjust the scanning process accordingly. This feedback ensures that the detector maintains proper spacing from the hose and that all sections are thoroughly tested, improving reading accuracy while keeping the operation straightforward through automated control.

AI summary
A hose-attaching apparatus for leak-testing a pressurized hose may include a hose-attaching member. A bore may extend through the hose-attaching member. An internal annular cavity may extend coaxially around the bore. At least one of a detector probe hole and a detector probe may be connected to the internal annular cavity. At least a portion of the bore may have a diameter which is at least one of substantially equal to and less than a diameter of a hose to be leak-tested.
