Vent Chamber Leak Indicator With Overpressure-Triggered Poppet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to detect leaks in pressurized fluid apparatuses, particularly in vent chambers, leading to late detection and damage, especially when the leak involves invisible or volatile fluids, resulting in inefficiency and costly repairs.
Innovation Solution
An indicator system comprising a support tube and a poppet that moves between initial and signaling positions in response to overpressure, allowing for immediate detection of leaks by visual observation or electronic alert, with the poppet locking in place to prevent further fluid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection is used to detect leaks, then detection is possible for visible leaks, but detection is delayed and unreliable for invisible or volatile fluids
Solution Approach 1:
The patent replaces manual visual inspection with an automated pressure sensing system. A pressure sensor detects pressure changes in the vent chamber caused by leaks, converting an unreliable visual task into a reliable automated measurement system that works for all fluid types including invisible and volatile ones.
Solution Approach 2:
The patent introduces a vent chamber as an intermediary space that collects leaked fluids before they cause damage. This vent chamber, combined with pressure sensing, acts as a mediator that makes all leaks detectable through pressure changes regardless of fluid visibility or volatility.
2Device complexity
If no leak detection system is installed, then the apparatus structure remains simple, but leaks cause significant damage and inefficiency
Solution Approach 1:
The patent implements preliminary leak detection through pressure monitoring in the vent chamber. By detecting leaks early through pressure changes before they cause significant damage, the system prevents harmful effects while maintaining relatively simple structure. The vent chamber itself serves as a preliminary containment measure.
Solution Approach 2:
The vent chamber acts as a cushioning element that预先 contains leaked fluids, preventing them from causing immediate damage to other components. This beforehand cushioning, combined with pressure sensing, allows the system to tolerate leaks without significant harm while maintaining structural simplicity.
3Productivity
If late leak detection occurs, then repair costs and downtime increase, but adding detection systems increases device complexity
Solution Approach 1:
The pressure sensing system in the vent chamber provides self-service leak detection without requiring complex external monitoring systems. The vent chamber's natural pressure changes from leaks are directly sensed, allowing the system to monitor itself and alert operators to maintenance needs, thereby maintaining productivity with minimal added complexity.

AI summary
An indicator, for indicating an occurrence of a leak of pressurized fluid in a vent chamber of a pressurized fluid apparatus, the indicator comprising a support tube, including a connection opening, fluidically connected to the vent chamber of the pressurized fluid apparatus, and an external opening, coming out to an outside. The indicator comprises a poppet, movable in the support tube, between an initial position and a signaling position, under the effect of an overpressure occurring at the connection opening, the poppet being positioned further from the connection opening in the signaling position than in the initial position, so as to indicate the occurrence of the leakage of pressurized fluid into the vent chamber when the poppet is in the signaling position.
