Hose Leak Detection Using Optical Fiber Slot Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid lines, particularly where hoses meet fittings, are prone to leaks due to wear, temperature fluctuations, corrosion, and other degenerative factors, and existing leak detection systems are inadequate in effectively identifying and addressing these leaks.
Innovation Solution
A leak detection system incorporating a ring with lateral slots and optical fibers connected to a light source and receiver, which transmits light across the slots and detects leaks by blocking or deflecting light when fluid passes through, triggering an alarm through a sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing leak detection systems use strain-sensing layers or electrical leads, then leak detection is attempted, but the systems are inadequate in effectively identifying and addressing leaks
Solution Approach 1:
The patent replaces mechanical/electrical sensing systems with an optical detection system. Instead of using strain-sensing layers or electrical leads, the invention employs a light source and optical fiber to detect leaks. The optical fiber transmits light through the hose wall, and when fluid leaks onto the outer surface, it blocks or deflects the light, providing a reliable and effective leak detection mechanism that overcomes the inadequacies of previous mechanical and electrical systems.
2Reliability
If a ring with lateral slots and optical fibers is used, then light transmission blocking detects leaks effectively, but the device structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the hose detection surface into discrete lateral slots around the ring. Instead of using a continuous sensing surface, the slots are segmented openings that allow light to pass through at specific locations. This segmentation simplifies the overall structure while maintaining effective leak detection, as leaks blocking light in any slot are reliably detected.
Solution Approach 2:
The ring structure serves multiple functions simultaneously: it provides mechanical support, defines the detection zones through lateral slots, and facilitates light transmission. The optical fiber integrated into the ring performs both light transmission and leak detection. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while maintaining high detection reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively detects leaks by raising an alarm when light transmission is blocked, providing real-time notification of leaks and preventing damage from combustible fluids, while being adaptable to various fluid line sizes and materials.
Implementation Method 1
an optical fiber disposed within the ring in a circumferential direction. The optical fiber has a first end connected to the light source and a second end disposed on one of the first and second slot walls of the at least one lateral slot, thereby transmitting light across the at least one lateral slot
Implementation Method 2
At least one optic fiber light receiver is circuit disposed on one of the first and second slot walls of the at least one lateral slot in a location opposite the second end of the optical fiber such that it receives the light transmitted across the at least one lateral slot

AI summary
A hose leakage detection system includes a ring configured to be disposed within a hose. The ring has a lateral slot formed in an outer surface, defining a first slot wall and a second slot wall. A sensor is disposed on one of the first slot wall and the second slot wall and a power source is electrically connected to the leakage detection system.
