Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a central control system is used to drive segments, then control precision is improved, but device complexity increases
Solution Approach 1:
Each segment contains its own radiation emitting semiconductor chip and radiation detecting semiconductor chip, enabling the segment to detect optical signals and control its own illumination independently without requiring a complex central control system. This self-contained design reduces overall system complexity while maintaining precise local control capability.
Solution Approach 2:
The optoelectronic component is divided into multiple independently controllable segments, each with its own semiconductor chips for illumination and detection. This segmentation allows distributed control where each segment operates autonomously based on local optical feedback, eliminating the need for a complex centralized control architecture.
2Illumination intensity
If all segments are illuminated simultaneously, then illumination intensity is improved, but energy consumption increases
Solution Approach 1:
Instead of illuminating all segments simultaneously, the system activates only the specific segments needed for particular illumination or detection tasks. The radiation emitting semiconductor chips in individual segments can be selectively driven based on the optical signals detected, reducing overall energy consumption while maintaining sufficient illumination intensity for the required application.
Solution Approach 2:
The system can employ periodic or pulsed illumination patterns where segments are activated in sequences rather than continuously. This allows the radiation emitting semiconductor chips to provide sufficient illumination intensity during active periods while minimizing energy consumption during inactive periods, achieving energy-efficient operation.
3Measurement precision
If manual addressing of segments is used, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system replaces manual addressing mechanisms with automatic optical signal-based identification and control. The radiation detecting semiconductor chips capture optical signals that automatically identify and address the appropriate segments for illumination or detection, eliminating the need for manual configuration or addressing while maintaining precise control.
Solution Approach 2:
The segments automatically identify themselves and respond to optical signals without requiring manual addressing. The radiation detecting semiconductor chips detect incoming optical signals and trigger the appropriate radiation emitting semiconductor chips to illuminate specific regions, enabling automatic and intuitive operation.
4Adaptability or versatility
If segments are controlled independently, then adaptability is improved, but device complexity increases
Solution Approach 1:
The optoelectronic component is segmented into independently controllable units, each with its own radiation emitting and detecting semiconductor chips. This segmentation enables high adaptability as each segment can be controlled independently for different illumination or detection tasks, while the modular design keeps the complexity of individual segments manageable.
Solution Approach 2:
Each segment is designed as a universal module that can perform multiple functions - both illumination and detection - using integrated semiconductor chips. This multi-functionality at the segment level provides system-wide adaptability for various applications while avoiding the need for complex specialized subsystems.
