Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing test equipment with singular measurement functions is used, then the device complexity is reduced, but the adaptability for measuring multiple cable parameters simultaneously deteriorates
Solution Approach 1:
The patent implements a dual-test-circuit architecture where the main test circuit and secondary test circuit can independently perform different measurement functions (cable length, wire sequence, continuity). This multi-functionality allows a single device to measure multiple cable parameters simultaneously, resolving the contradiction between adaptability and device complexity by integrating diverse functions into one unified system.
Solution Approach 2:
The testing device is divided into independent functional modules: main test circuit with first pairing and tracing module, secondary test circuit with second pairing and tracing module, audio output module, and running lights modules. Each module handles specific measurement tasks, allowing the system to achieve multi-parameter measurement capability while maintaining manageable complexity through modular design.
2Adaptability or versatility
If multiple test circuits are integrated to measure multiple parameters, then the adaptability improves, but the ease of operation deteriorates due to increased system complexity
Solution Approach 1:
The patent combines the output interfaces of both test circuits into unified display components: the first running lights module and second running lights module are integrated to simultaneously display wire sequence information from both ends of the cable. The audio output module also provides unified audio feedback for tracing signals. This merging of multiple output channels into single integrated display systems simplifies the user interface and improves ease of operation despite the complex internal architecture.
3Productivity
If singular measurement functions are used, then the device complexity is low, but the productivity for comprehensive cable testing deteriorates
Solution Approach 1:
The main test circuit and secondary test circuit operate simultaneously and independently, allowing continuous measurement of multiple cable parameters (length, wire sequence, continuity) without requiring sequential testing. This parallel operation enables comprehensive cable testing to be completed in a single continuous process, significantly improving productivity despite the increased system architecture complexity.

AI summary
The present application relates to the technical field of cable testing, disclosing a cable testing device for running lights wire pairing and tracing and a cable tester. By utilizing a main test circuit and a secondary test circuit, the device/tester jointly implements running lights wire pairing and tracing functions for a cable to be test: By implementing, at a first data processing module in the main test circuit, target signal generation and transmission down including a pairing signal and a tracing signal, the first pairing and tracing module cooperates with the first running lights module to respond to the target signal, while the second pairing and tracing module in the secondary test circuit cooperates with the second running lights module to respond to the target signal.
