Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogen gas filling devices require labor and time to detect the disconnection of the disconnect coupling, which can be challenging especially when the inner pressure of the hose is not applied, and existing solutions complicate the attachment process with additional sensors or members that require replacement.
Innovation Solution
A hydrogen gas filling device with a disconnect coupling that includes a first coupler and a second coupler connected under normal conditions, and a detecting device with a detecting part and a moving part integrated into the disconnect coupling, allowing for the detection of disconnection without the need for additional sensors or complex attachment processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a disconnect coupling is provided in the hydrogen gas filling device, then safety is improved by enabling disconnection during emergencies, but device complexity increases due to the need for additional components
Solution Approach 1:
The patent combines the disconnect coupling function with the detection function into a single integrated mechanism. The detecting device is incorporated within the disconnect coupling structure itself, merging safety disconnection capability with detection capability. This reduces the number of separate components while maintaining both safety and detection functions.
Solution Approach 2:
The disconnect coupling is designed to serve multiple functions: it enables emergency disconnection of the hose and simultaneously detects the disconnected state. The same structural components that enable disconnection also facilitate detection, making the device multi-functional and reducing overall system complexity.
2Measurement precision
If a detecting device is added to detect disconnect coupling disconnection, then measurement capability is improved, but device complexity and attachment labor increase
Solution Approach 1:
The detecting device is merged with the disconnect coupling structure. The detection components are integrated within the coupling mechanism itself, eliminating the need for separate attachment of detection sensors. This reduces installation labor and simplifies the overall device structure while maintaining detection capability.
Solution Approach 2:
The disconnect coupling structure itself provides the detection capability through its own components. The coupling mechanism's structural elements serve dual purposes: enabling disconnection and detecting the disconnected state. This self-service approach eliminates the need for additional external detection devices and their associated installation complexity.
3Measurement precision
If additional detecting components are attached to the disconnect coupling, then detection capability is improved, but attachment time and labor increase
Solution Approach 1:
The detection components are merged into the disconnect coupling structure during manufacturing, creating an integrated assembly. This eliminates the need for separate attachment of detection components during installation, significantly reducing attachment time and labor while maintaining full detection capability.
Solution Approach 2:
The detection components are pre-integrated into the disconnect coupling structure during the manufacturing process. This preliminary action of combining components before deployment eliminates the need for time-consuming on-site attachment of detection devices, reducing installation time and labor requirements.

AI summary
An emergency breakaway coupling, which is a disconnect coupling, is configured such that a first coupler and a second coupler thereof are connected under normal conditions and the first coupler and the second coupler are disconnected during an emergency. A disconnect detecting device includes a detecting piece and a moving piece that are arranged in the emergency breakaway coupling. The disconnect detecting device detects the disconnect of the emergency breakaway coupling due to the movement of the moving piece from the detecting piece. The detecting piece and the moving piece are arranged in the emergency breakaway coupling such that a moving direction O2-O2 of the moving piece moving from the detecting piece is in parallel with a disconnecting direction O1-O1 of the first coupler disconnecting from the second coupler.
