High-Pressure Tank Venting Layout for False Leak Detection Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high pressure tank apparatuses with resin-made liners, there is a risk of fluid permeation between the liner and the reinforced layer, leading to temporary release fluid being mistakenly detected as leaked fluid during normal operation, which can trigger false alarms for abnormalities.
Innovation Solution
A high pressure tank apparatus with a separate storage section for leaked fluid and a discharge path for temporary release fluid, equipped with a detecting unit and control section to differentiate between normal and abnormal fluid discharge, ensuring appropriate timing for discharging temporary release fluid to the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor is used to detect leaked fluid in the storage section, then leakage detection capability is improved, but false detection occurs when temporary release fluid enters the storage section during normal operation
Solution Approach 1:
The patent divides the storage section into multiple independent storage spaces: a first storage space for receiving temporary release fluid and a second storage space for detecting leaked fluid. This segmentation prevents temporary release fluid from contaminating the detection space, thereby eliminating false detections while maintaining reliable leakage detection capability.
Solution Approach 2:
The patent extracts the temporary release fluid detection function from the leaked fluid detection system by providing a separate first storage space specifically for temporary release fluid. This extraction allows the sensor in the second storage space to detect only leaked fluid without interference from temporary release fluid, resolving the false detection issue.
2Stability of the object's composition
If temporary release fluid is discharged to the air during normal operation, then fluid accumulation in the covered section is prevented, but false alarm is triggered by the sensor mistaking temporary release fluid for leaked fluid
Solution Approach 1:
The patent segments the storage section into a first storage space connected to the lead-out hole for temporary release fluid and a second storage space for leaked fluid detection. This segmentation enables temporary release fluid to be discharged to the air through the first storage space without triggering false alarms in the second storage space, thus maintaining both structural integrity and detection reliability.
Solution Approach 2:
The first storage space acts as an intermediary between the lead-out hole and the sensor, allowing temporary release fluid to be temporarily stored and discharged without reaching the sensor. This intermediary structure prevents false alarms while still enabling the discharge function to maintain structural integrity.
3Device complexity
If a single storage section is used for both temporary release fluid and leaked fluid, then device complexity is reduced, but false detection of leaks occurs during normal operation
Solution Approach 1:
The patent divides the storage section into multiple independent storage spaces with different functions: one for temporary release fluid and another for leaked fluid detection. This segmentation improves measurement precision by enabling fluid type differentiation, while the integrated design of the storage section keeps the overall device complexity manageable.

AI summary
A high pressure tank of a high pressure tank apparatus includes: a resin-made liner; a reinforced layer; a supplying/discharging hole to which a supplying/discharging flow path is connected via a connecting section; and a supplying/discharging-side lead-out hole that leads out a fluid interposing between the liner and the reinforced layer. A leaked fluid storage section is capable of storing a leaked fluid that has leaked from the connecting section. A supplying/discharging-side discharge flow path is provided independently from the leaked fluid storage section, and, when an opening/closing valve opens, discharges to the air a temporary release fluid that has been led out via the supplying/discharging-side lead-out hole. A control section, when it has judged, based on a detection result of a detecting unit, that there is a condition enabling the temporary release fluid to be discharged, opens the opening/closing valve.
