Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a continuity tester is integrated into a circuit tracer transmitter, then device complexity is reduced and ease of operation is improved, but manufacturing precision and reliability requirements increase
Solution Approach 1:
The patent combines the continuity tester and circuit tracer transmitter into a single integrated device. The continuity test circuit shares the transformer and test leads with the circuit tracing function, eliminating the need for separate devices while maintaining reliable continuity testing capability through dedicated test circuitry.
Solution Approach 2:
The integrated device performs multiple functions: continuity testing, circuit tracing, and fault location. The same transformer and test leads are used for both continuity testing and signal transmission for tracing, making the device universal for various electrical testing applications.
2Object-affected harmful factors
If high voltage protection components are added to continuity testers, then safety is improved, but device size and cost increase
Solution Approach 1:
The continuity test circuit is integrated into the existing circuit tracer transmitter architecture, sharing the transformer and power supply. This eliminates the need for separate high voltage protection components that would be required in a standalone continuity tester, reducing overall device size while maintaining safety.
Solution Approach 2:
The transformer acts as an intermediary that isolates the low-voltage continuity test circuitry from the high-voltage AC lines. This provides inherent high voltage protection without requiring additional protection components, as the transformer naturally blocks hazardous voltages from reaching the test circuitry.
3Measurement precision
If separate continuity testing devices are used, then measurement precision is maintained, but productivity decreases due to multiple steps
Solution Approach 1:
By merging the continuity testing function with the circuit tracer transmitter, the patent enables technicians to perform both continuity testing and circuit tracing in a single operation. The test leads remain connected throughout the process, eliminating the need to disconnect and reconnect leads between testing phases, thereby improving productivity while maintaining measurement precision.
Solution Approach 2:
The continuity test is performed automatically as part of the circuit tracing process. The system first conducts continuity testing to identify shorted conductors, then automatically proceeds to signal transmission for fault location, eliminating the need for separate manual testing steps and improving overall testing efficiency.
