High Pressure Tank Fluid Detection Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pressure tank apparatuses with resin liners face issues where fluid intrusion between the liner and reinforced layer can lead to erroneous leakage sensing during normal operation, causing potential peeling and buckling, and existing configurations fail to separately contain leaked and temporarily released fluids effectively.
Innovation Solution
A high pressure tank apparatus with a separate leaked fluid container and supply/discharge side discharge flow path to guide temporarily released fluid to a predetermined region, preventing erroneous leakage sensing and reducing fluid accumulation, which includes a cover member to isolate the connecting portion and direct temporarily released fluid into the discharge flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a container and sensor are used to detect leaked fluid, then leakage detection capability is improved, but temporarily released fluid is erroneously sensed as leaked fluid causing false alarms
Solution Approach 1:
The patent divides the detection system into two separate containers: a first container for temporarily released fluid and a second container for leaked fluid. The sensor is positioned only in the second container to detect actual leaks. This segmentation prevents the sensor from detecting temporarily released fluid, thereby eliminating false alarms while maintaining accurate leakage detection capability.
2Productivity
If fluid is allowed to accumulate in the covered portion between liner and reinforced layer, then normal operation is maintained, but liner peeling and buckling occur reducing structural integrity
Solution Approach 1:
The patent extracts the temporarily released fluid from the covered portion between the liner and reinforced layer through a draw-out hole in the cap. By removing this fluid through the first container and discharge flow path, the system prevents liner peeling and buckling while maintaining normal operation, thus preserving structural integrity without interrupting productivity.
3Device complexity
If a single container is used for both temporarily released fluid and leaked fluid, then device complexity is reduced, but fluid differentiation capability is lost
Solution Approach 1:
The patent implements segmentation by providing two separate containers: a first container connected to the draw-out hole for temporarily released fluid, and a second container for leaked fluid. This segmentation enables clear differentiation between fluid types, allowing the sensor to accurately detect only leaked fluid without interference from temporarily released fluid, thus maintaining measurement precision.
4Strength
If the draw-out hole is positioned to effectively remove temporarily released fluid, then liner protection is improved, but the connecting portion becomes exposed to potential leakage
Solution Approach 1:
The patent extracts temporarily released fluid through the draw-out hole positioned in the cap, effectively protecting the liner from peeling and buckling. The sensor is positioned in a separate second container that receives only leaked fluid from the connecting portion, allowing continuous monitoring of leakage at the exposed connecting portion without interference from the fluid extraction process.

AI summary
A high pressure tank apparatus includes a high pressure tank, a leaked fluid container, and a supply/discharge side discharge flow path. The high pressure tank includes a liner made of resin, a reinforced layer that covers an outer surface of the liner, an insertion member that has formed therein a supply/discharge hole capable of communicating with an inside of the liner and the supply/discharge flow path; and a supply/discharge side cap in which are formed an insertion hole through which the insertion member is inserted and a supply/discharge side draw-out hole that draws out the fluid interposed between the liner and the reinforced layer. The supply/discharge side discharge flow path guides a temporarily released fluid that is the fluid drawn out via the supply/discharge side draw-out hole to a discharge region.
