Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the emission optical axis is corrected according to the error amount of the angle error detected by the light receiving angle detection device, then the orientation of the light receiving system and the light transmission axis can be adjusted when the direction of the communication target is determined, but spatial optical communication cannot be established with a communication target disposed in an arbitrary azimuth
Solution Approach 1:
The patent employs a rotation mechanism that can dynamically adjust the orientation of the light receiving system in arbitrary azimuths. The rotation mechanism includes a rotation axis that allows the light receiving system to rotate and reorient itself toward communication targets at any azimuth angle, transforming a static alignment system into a dynamic one that adapts to various target positions.
Solution Approach 2:
The patent introduces a new degree of freedom by adding rotational capability around a vertical axis. This additional dimension of motion enables the light receiving system to not only adjust its orientation in the traditional sense but also to sweep through a full 360-degree azimuth range, effectively adding a rotational dimension to the alignment process.
2Reliability
If accurate matching of transmission direction and reception direction is achieved, then spatial optical communication can be easily established, but it is difficult to accurately match the transmission direction and reception direction
Solution Approach 1:
The patent incorporates a light receiving angle detection device that continuously monitors the alignment status and provides feedback signals. This feedback mechanism detects angle errors in real-time and feeds this information back to the control system, which then adjusts the rotation mechanism to correct the misalignment, creating a closed-loop control system that automatically maintains accurate alignment.
Solution Approach 2:
The system performs self-alignment through the automated feedback loop. The light receiving angle detection device automatically detects alignment errors and the rotation mechanism automatically corrects them without requiring manual intervention, enabling the system to self-adjust and maintain optimal communication alignment.
