Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cartridge couplings in the prior art suffer from non-optimal reliability in terms of resistance and duration, and have large overall dimensions, making them less effective in high-pressure applications and difficult to use in confined spaces.
Innovation Solution
A compact cartridge coupling design with a decompression system and mechanical blocking means that reduces pressure within the coupling, facilitating easier coupling and uncoupling operations, and allowing the valve assembly to complete insertion regardless of flow direction and pressure, using a female half-coupling with a clean oil recovery channel and fouled oil draining channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If cartridge couplings are designed with compact dimensions for narrow spaces, then the overall size is reduced, but the reliability and resistance under high pressure conditions deteriorate
Solution Approach 1:
The coupling system is divided into a compact cartridge assembly and an external casing, separating the functional components from the protective housing. This allows the cartridge to maintain small dimensions while the casing provides structural strength and pressure containment.
Solution Approach 2:
The patent incorporates a decompression system with relief channels and spring-loaded valves that activate before pressure reaches critical levels. This preliminary pressure relief mechanism prevents sudden pressure spikes from compromising the compact cartridge structure, thereby maintaining reliability without increasing size.
2Stress or pressure
If cartridge couplings are designed for high pressure applications, then pressure resistance is improved, but the coupling and uncoupling loads increase making operations difficult
Solution Approach 1:
The decompression system performs preliminary pressure relief by diverting excess pressure through relief channels before coupling operations. The spring-loaded valves open at predetermined pressure thresholds, reducing the actual coupling/uncoupling loads to manageable levels while maintaining high operating pressure capability.
Solution Approach 2:
The patent introduces decompression channels and relief valves as intermediary elements between the high-pressure fluid and the coupling mechanism. These intermediaries absorb and redirect pressure forces, protecting the coupling operation from direct high-pressure loads while maintaining system pressure resistance.
3Stress or pressure
If cartridge couplings operate in high pressure pulsating conditions, then pressure handling capability is improved, but component durability and reliability deteriorate
Solution Approach 1:
The decompression system with relief channels and spring-loaded valves provides beforehand cushioning against pressure pulsations. By activating before pressure reaches damaging levels, the system protects components from repeated stress cycles, thereby extending component duration and reliability under high-pressure pulsating conditions.
Solution Approach 2:
The patent changes the pressure parameter dynamics by introducing decompression channels that actively regulate pressure fluctuations. The spring-loaded valves modify the pressure waveform by releasing peaks, transforming extreme pulsating conditions into more stable pressure variations that component can withstand for longer durations.
4Ease of operation
If mechanical blocking means are added to prevent valve closure during insertion, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The mechanical blocking means are merged with the existing valve assembly structure and decompression system. The blocking function is integrated into the same mechanical components that provide pressure relief, combining multiple functions without proportionally increasing complexity. The spring-loaded mechanism serves both decompression and blocking purposes.
