Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel systems face challenges in securing limited mounting space and simplifying assembly operations due to the separate installation of multiple parts in the supply lines of hydrogen tanks to fuel cells, complicating the assembly process.
Innovation Solution
Integration of a pressure reducing valve and a pressure sensor into a single assembly that functions as a pipe fitting in the supply line, allowing for improved mountability and assembly ease, with additional sensors and valves optionally integrated for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple parts (pressure reducing valve, pressure sensor, leakage check port) are installed separately in the supply line, then each part can be independently selected and replaced, but the mounting space requirement increases and assembly operations become complicated
Solution Approach 1:
The patent combines the pressure reducing valve, pressure sensor, and leakage check port into a single integrated assembly that functions as a pipe fitting. This merging reduces the number of separate components to be mounted, thereby decreasing the total mounting space required while maintaining the functional capabilities of each individual part.
Solution Approach 2:
The integrated assembly serves multiple functions simultaneously: it acts as a pipe fitting for fluid flow, a pressure reducing valve for pressure control, a pressure sensor for pressure detection, and a leakage check port for system verification. This multi-functionality eliminates the need for separate mounting locations for each component.
2Ease of repair
If multiple parts are installed separately in the supply line, then each part can be independently maintained, but assembly operations become complicated and time-consuming
Solution Approach 1:
By integrating multiple parts into a single assembly, the patent reduces the number of assembly operations required during installation. Instead of separately mounting the pressure reducing valve, pressure sensor, and leakage check port, the integrated assembly is installed as one unit, significantly simplifying the assembly process and reducing installation time.
3Area of stationary object
If parts are integrated into a single assembly, then mounting space is reduced and assembly operations are simplified, but the complexity of the integrated component increases
Solution Approach 1:
The integrated assembly is designed to perform multiple functions within a single component structure. The assembly includes a body that houses the pressure reducing valve mechanism, incorporates a pressure sensor for detection, and provides a leakage check port. This multi-functional design achieves space efficiency while managing complexity through functional integration.

Function Achieved in This Case
The integrated assembly reduces the complexity and time required for piping assembly, improves mountability, and allows for effective leakage checks, while also reducing the risk of damage to high-pressure tanks during collisions.
Implementation Method 1
a first pressure sensor adapted to detect primary or secondary pressure of the pressure reducing valve
