Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single light emitting element and light receiving element are used, then the device complexity is low, but the information acquisition capability degrades under vehicle vibration
Solution Approach 1:
The sensor system is divided into multiple independent detection units, each comprising a light emitting element and a light receiving element. Each unit can independently detect light in different directions, allowing the system to maintain information acquisition capability even when vehicle vibration causes misalignment in certain units.
Solution Approach 2:
Multiple detection units are combined into a single sensor system that integrates their detection results. The processor combines data from all units to generate comprehensive detection information, thereby improving overall reliability while distributing the impact of vibration across multiple units.
2Reliability
If multiple light emitting elements and light receiving elements are used to counteract vibration effects, then the information acquisition capability is maintained, but the device complexity increases
Solution Approach 1:
Each detection unit is designed with universal functionality to detect light from multiple directions. The light emitting elements and light receiving elements are configured to handle various incident angles, allowing each unit to serve multiple detection purposes and reducing the need for even more complex specialized components.
Solution Approach 2:
The detection units are arranged in a three-dimensional configuration with different spatial orientations. This dimensional arrangement allows the system to detect light from multiple directions simultaneously, compensating for vibration-induced misalignment without requiring an excessive number of components in a single plane.
3Reliability
If data exchange and averaging processing are implemented, then the information processing capability under vibration is suppressed, but the processing complexity increases
Solution Approach 1:
The processor implements a feedback mechanism where detection data from multiple units is continuously exchanged and compared. When vibration causes abnormal readings in certain units, the system uses feedback from other units to identify and correct anomalies through averaging processing, maintaining reliable information processing.
Solution Approach 2:
The processor dynamically changes processing parameters based on vibration detection. When vibration is detected, the system activates data exchange and averaging processing with adjusted weights and thresholds, optimizing the balance between processing reliability and computational complexity under different operating conditions.

Data Source
AI summary
A first light emitting element emits first detecting light toward the outside of a vehicle. A second light emitting element emits second detecting light toward the outside of the vehicle. A first light receiving element outputs a first signal corresponding to an amount of incident light. A second light receiving element outputs a second signal corresponding to an amount of incident light. A processor acquires first data corresponding to the first signal and second data corresponding to the second signal, and exchanges the first data and the second data in a case where the first data is based on the second detecting light and the second data is based on the first detecting light.
