Solution Overview
Problem
Existing methods for fluid leakage detection in industrial processes, particularly in tight shut-off valves, are inadequate as they cannot effectively detect leaks through closed valves between upstream and downstream pipes, posing hazards and environmental risks.
Innovation Solution
A device with a fluid collection compartment and a fluid level switch is installed below the fluid drain pipe to detect leaks through closed valves, eliminating the need for pressure, temperature, or vapor sensors, and featuring a simple operation with minimal intricacies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature level sensors and pressure level sensors are installed in chambers/tanks to detect fluid leakage, then leakage detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts the detection function from complex sensors and implements it through a simple fluid collection compartment with a level switch. The collection compartment captures leaked fluid and the level switch detects when a predetermined amount has accumulated, providing leakage detection without requiring temperature or pressure sensors.
Solution Approach 2:
The invention replaces expensive, complex sensors with a simple, economical detection mechanism using a collection compartment and level switch. This approach uses readily available, low-cost components that are easier to install and maintain while achieving the same leakage detection objective.

3Measurement precision
If existing sensor-based approaches are used for leakage detection, then detection accuracy is improved, but ease of operation deteriorates due to complex operation and maintenance
Solution Approach 1:
The invention extracts the detection function from complex sensors and implements it through a simple fluid collection compartment with a level switch. The collection compartment captures leaked fluid and the level switch detects when a predetermined amount has accumulated, providing leakage detection without requiring temperature or pressure sensors.
Solution Approach 2:
The collection compartment automatically collects leaked fluid and the level switch automatically detects when the predetermined amount is reached, triggering an alarm without requiring complex operation or calibration. The system is self-regulating and easier to operate than sensor-based systems.
