Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve devices for high-pressure gas tanks face challenges during maintenance, where manual operation of valves can be hindered by interference with peripheral devices, leading to decreased ease of work and potential pressure-related issues.
Innovation Solution
The valve device incorporates a solenoid valve and a manual valve with intersecting flow channels and center axes, preventing interference during manual operation, and includes a mounting member that allows pressure release without dedicated components, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the solenoid valve and manual valve are arranged in a conventional configuration, then the valve device structure is simple, but the tool interferes with peripheral devices during manual operation
Solution Approach 1:
The patent applies dimensional arrangement by positioning the solenoid valve and manual valve on different surfaces of the body. The solenoid valve is mounted on a first surface while the manual valve is mounted on a second surface that is different from the first surface. This spatial separation in multiple dimensions prevents tool interference during manual operation while maintaining structural simplicity.
2Ease of operation
If the manual valve is positioned on the same surface as the solenoid valve, then the device structure is compact, but the tool interferes with the solenoid valve and connection members
Solution Approach 1:
The patent resolves the conflict between ease of operation and device compactness by utilizing multiple surfaces of the body. The solenoid valve and manual valve are arranged on different surfaces, which are spatially separated. This approach maintains compactness by keeping all components within the same valve device assembly while preventing tool interference through surface separation.
3Productivity
If separate piping is used for gas charge and supply, then the gas flow control is precise, but the number of connection members increases
Solution Approach 1:
The patent implements multi-functionality by enabling the gas flow channel to serve multiple purposes. The same gas flow channel is used for both gas charge into the tank and gas supply from the tank, controlled by the solenoid valve's opening and closing actions. This eliminates the need for separate piping systems while maintaining precise gas flow control through the valve mechanisms.

AI summary
A valve device includes a body, a solenoid valve, and a manual valve mounted to the body. The manual valve being configured to open and close the gas flow channel via a manual operation. The gas flow channel includes a first flow channel including the valve-side opening portion, and a second flow channel including the tank-side opening portion, and includes an intersection portion in which a first center axis that is a center axis of the first flow channel and a second center axis that is a center axis of the second flow channel intersect with each other. A center axis of the solenoid valve coincides with an extension line of the first center axis and a center axis of the manual valve coincides with an extension line of the second center axis.
