Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a high-voltage power source device applies high-voltage electricity to an electrical wire without a receiving terminal, then the device structure is simple, but disconnection or electrical leakage of the electrical wire cannot be detected
Solution Approach 1:
The patent introduces a receiving terminal as an intermediary component that enables voltage measurement without directly complicating the high-voltage generation system. This mediator allows the detection system to safely measure the voltage state of the electrical wire, resolving the contradiction between structural simplicity and detection capability.
2Reliability
If a light-emitting element is used to display electrical leakage, then electrical leakage can be monitored, but the location of electrical leakage cannot be identified
Solution Approach 1:
The patent divides the electrical wire into multiple sections by introducing intermediate terminals at different locations. Each segment can be independently monitored for voltage, enabling both detection of electrical leakage and identification of its specific location along the wire.
3Loss of information
If voltage measurement devices are disposed at each predetermined position of the electrical wire, then abnormality location can be identified, but the number of devices and communication capacity required increase
Solution Approach 1:
The receiving terminal serves multiple functions: it acts as an endpoint for the electrical wire, provides a measurement point for voltage detection, and enables location identification. This multi-functional design eliminates the need for separate dedicated measurement devices at each position.
4Device complexity
If periodic visual checks are performed to detect abnormalities, then no additional detection equipment is needed, but the risk of animal intrusion increases and maintenance efficiency decreases
Solution Approach 1:
The patent implements a feedback system where the voltage detection unit continuously monitors the electrical wire state and provides real-time information about abnormalities. This automatic feedback mechanism replaces manual visual checks, improving maintenance efficiency and reducing animal intrusion risk without requiring complex additional equipment.
