Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional leak detection systems are installed, then leak detection capability is improved, but installation complexity and infrastructure changes increase
Solution Approach 1:
The patent replaces traditional mechanical or electronic sensor-based leak detection systems with a video-based optical detection system. Color video cameras capture images of the monitoring area, and image analysis algorithms detect leaks by analyzing color changes in the video feed, eliminating the need for complex physical installation of sensors within the equipment infrastructure.
Solution Approach 2:
The system creates a visual copy of the monitoring area through video capture and uses this copied visual information for leak detection. By analyzing the video feed that replicates the scene, the system can detect leaks without physically interacting with or modifying the equipment structure, thus reducing installation complexity.
2Reliability
If traditional leak detection systems are installed, then leak detection capability is improved, but equipment operation is disturbed
Solution Approach 1:
The patent introduces video cameras as an intermediary detection medium that observes the equipment from a distance without interfering with its operation. The cameras capture visual information about leaks occurring on or near the equipment, allowing detection to proceed while the equipment continues to operate normally without disruption.
3Reliability
If traditional leak detection systems are installed, then leak detection capability is improved, but system cost increases
Solution Approach 1:
The patent employs color video cameras and software-based image analysis, which are generally more cost-effective than specialized industrial leak detection sensors and systems. The use of standard video technology and algorithmic analysis provides a lower-cost alternative while maintaining effective leak detection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively detects leaks in real-time, preventing environmental damage and equipment damage without altering the existing infrastructure, allowing for easy installation and timely alerts for industrial applications.
Implementation Method 1
A video based leak detection system uses color video cameras to monitor pumps
Implementation Method 2
An alarm is activated when a leak is detected over a predetermined time interval... the image analyzer may determine if a leak on the equipment is present from the pixel values that are representative of color
Data Source
AI summary
Apparatus and corresponding method are invented for detecting indoor liquid leak in equipment, such as a pump in a pump station. The apparatus includes an image analyzer configured to receive video from one or more cameras and analyze the video to determine if a leak on the equipment is present by comparing the video with a reference and a target color and the image analyzer having an output port for delivering a notification upon the image analyzer determining that a leak is present on the equipment. If a leak alarm happens, the operator can check the remote live video and/or stored clips to confirm the leak and activate a response to stop it.
