Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional water detection methods are used, then water presence can be detected, but the ability to accurately locate and pinpoint leak sites is insufficient
Solution Approach 1:
The measuring unit is divided into multiple electrodes arranged in a lattice pattern, where each electrode or electrode pair can independently detect water presence. This segmentation allows the system not only to detect water but also to locate it by identifying which specific electrode or electrode pair detects the water, thereby providing both detection accuracy and location information simultaneously.
2Reliability
If a lattice pattern of conductors is used for detection, then water presence can be detected, but the system complexity increases
Solution Approach 1:
The lattice pattern of conductors serves multiple functions: it acts as both the detection element and the location identification system. The same conductor structure that detects water presence also provides spatial information through its geometric arrangement, eliminating the need for separate detection and location systems.
Solution Approach 2:
Voltage is applied between the substructure and the conductors, creating equipotential surfaces that facilitate uniform detection across the entire lattice pattern. This equipotential approach simplifies the measurement process by providing consistent electrical conditions across all detection points.
3Reliability
If voltage is applied between substructure and conductors with relays for testing, then leak detection is possible, but the operational complexity and time consumption increase
Solution Approach 1:
The measuring unit itself performs the detection function without requiring external relays or complex testing procedures. By directly measuring electrical properties (such as conductivity changes) between the substructure and conductors, the system achieves reliable leak detection while simplifying the operational process.

AI summary
In a method for detecting the presence of water or additional water, which exists because of a leak, the following steps are carried out: attaching at least one pair of electrodes to/in an object, to/in the presence of water is to be determined; applying an electrical voltage between the electrodes; testing whether electrical current or electrical current that is increased relative to a basic current flows between the electrodes; and detecting the presence of water in the case of flowing current. When implementing the method, at least two electrodes are used, wherein one electrode can be a ground. The electrodes are arranged separated from one another. DC or AC voltage is applied to the electrodes by a device. The device detects a measured value corresponding to the intensity of the current flowing between the electrodes.
