Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing testing solution using all-in-one FTTH user end ONU device and traffic flow meter is used, then the OLT device can be tested through connection with user end device, but the testing process requires frequent insertion and drawing out of optic fibers resulting in misoperations and time-consuming corrections
Solution Approach 1:
The patent extracts the optical fiber connection function from the testing process by introducing an electrical interface module that provides direct electrical connections. This separates the optical fiber insertion/drawing operations from the testing workflow, eliminating the need for repeated fiber connections and reducing misoperations.
Solution Approach 2:
The electrical interface module acts as an intermediary device between the OLT device and the testing system. It provides electrical signal interfaces that mediate the connection, replacing the need for direct optical fiber connections and manual plugging/unplugging operations.
2Productivity
If the existing testing solution is used, then the OLT device can be tested through complicated environment setup, but the testing efficiency is low and valuable production time is wasted
Solution Approach 1:
The patent merges multiple testing functions into a single electrical interface module that integrates signal processing, switching, and connection capabilities. This consolidation simplifies the testing environment from a complicated setup with multiple devices to a single integrated module, improving productivity.
Solution Approach 2:
The electrical interface module provides multi-functionality by supporting both optical and electrical interfaces, enabling it to work with different types of devices and testing scenarios. This universal design reduces the need for specialized testing equipment and simplifies the overall testing environment.
3Reliability
If the existing testing solution is used, then the OLT device can be tested through connection with user end device, but the testing cost increases due to complicated setup and time consumption
Solution Approach 1:
The electrical interface module performs preliminary signal processing and conditioning before signals are transmitted to the OLT device. This preliminary action ensures that signals are properly prepared in advance, eliminating the need for repeated testing and corrections, thus reducing testing time while maintaining accuracy.
4Ease of operation
If the electrical interface module is used to simplify the testing environment, then the testing process is simplified and efficiency is improved, but a new testing device needs to be introduced
Solution Approach 1:
The electrical interface module is designed with universal compatibility to work with existing OLT devices and testing systems. It provides both optical and electrical interfaces, allowing it to replace multiple specialized devices while maintaining compatibility with existing equipment, thus not increasing the overall number of devices needed.
