Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fiber optic cables are installed during new installation or upgrade, then communication lanes are established, but incorrect cables may be used leading to data transmission errors
Solution Approach 1:
The patent applies preliminary action by testing fiber optic cables before they are fully installed into the network. The testing tool verifies cable polarity and communication lane integrity in advance, allowing incorrect cables to be identified and corrected before they cause data transmission errors in production use
Solution Approach 2:
The patent implements feedback by using a testing tool that sends test signals through communication lanes and receives test results to verify correct cable installation. The system provides immediate feedback on whether cables have correct polarity and whether communication lanes are properly established, allowing real-time correction of installation errors
2Adaptability or versatility
If multiple fiber optic cables with different polarities are used, then communication flexibility is improved, but difficulty in identifying correct cable connections increases
Solution Approach 1:
The testing tool provides automated feedback on cable polarity by sending test signals and analyzing the returned signals to determine if cables are correctly polarized. This eliminates manual verification difficulties and provides clear indication of correct or incorrect cable connections
Solution Approach 2:
The patent uses parameter changes by varying test signal characteristics (such as wavelength or signal pattern) to probe different communication lanes and detect cable polarity. The testing tool adjusts test parameters to verify correct cable installation across multiple cables with different polarities
3Manufacturing precision
If comprehensive testing of all communication lanes is performed, then installation accuracy is verified, but testing time increases
Solution Approach 1:
The testing tool performs comprehensive communication lane verification as a preliminary step before full network deployment. By testing all lanes early in the installation process, the system ensures high installation accuracy without delaying subsequent network operations
Solution Approach 2:
The patent implements continuous testing by sending multiple test signals through communication lanes in sequence without interruption. The testing tool maintains continuous operation to verify all lanes efficiently, minimizing total testing time while ensuring complete coverage
