Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveability to measure multiple cable parametersVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvemulti-parameter measurement capabilityVSAvoidoperational convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

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.

Inventive Principle:

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.

Inventive Principle:
Principle #20Continuity of useful action
