Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple measuring devices are coupled to multiple testing ports of each optical device, then comprehensive network characteristics can be measured, but device complexity and time required for testing increase
Solution Approach 1:
The patent combines multiple measuring devices into a single integrated test device that can perform multiple measurement functions. The optical device includes a single test port that provides access to multiple measurement points within the device, allowing one measuring device to replace multiple previous devices while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The single test port is designed to provide universal access to multiple internal measurement points of the optical device. A single measuring device connected to this port can measure various network characteristics including optical power, wavelength, and other parameters at different locations within the optical device, making the test port multi-functional.
2Measurement precision
If personnel physically access each optical device to attach measuring devices, then direct measurement is possible, but service disruption time increases
Solution Approach 1:
The optical device is pre-configured with internal couplers and a single accessible test port during manufacturing. This preliminary setup allows measuring devices to be connected without requiring personnel to physically access internal components of the optical device during field testing, reducing service disruption time while maintaining direct measurement capability.
Solution Approach 2:
The single test port acts as an intermediary that provides external access to multiple internal measurement points. Instead of requiring direct physical access to multiple internal locations, the test port mediates all measurement activities, allowing external measuring devices to interface with the optical device's internal characteristics through a single controlled interface.
3Measurement precision
If network disconnection is required to attach measuring devices, then measurement accuracy is improved, but productivity decreases
Solution Approach 1:
The optical device is designed to maintain network service continuity during measurement operations. The single test port is integrated into the operational device, allowing measurements to be taken while the network remains connected and operational. This eliminates the need to disconnect the network for testing, maintaining productivity while achieving measurement accuracy through the dedicated test interface.
