Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 2D calibration methods are used for 3D display systems, then the calibration process is simple and familiar, but the image quality and measurement precision are insufficient for critical applications
Solution Approach 1:
The sensor unit is divided into multiple independent detectors, each dedicated to detecting radiation properties for a specific eye (left or right). This segmentation allows precise separate measurement of sub-images for each eye, enabling accurate 3D display calibration while maintaining manageable system complexity through modular architecture
Solution Approach 2:
A filter is introduced as an intermediary component between the 3D display and sensor unit. The filter selectively transmits radiation corresponding to sub-images for specific eyes to the appropriate detectors, enabling precise separation and measurement of radiation properties without requiring complex sensor arrays or processing systems
2Manufacturing precision
If separate detection of radiation properties for each eye is implemented, then image quality and calibration accuracy are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The sensor unit employs multiple detectors of the same type and configuration, each serving the same detection function but dedicated to different eyes. This universal approach simplifies manufacturing by using identical components throughout, while still achieving the precision of separate detection for each eye through the modular replicated architecture
Solution Approach 2:
The detection system uses identical detector copies for each eye, with each copy configured to detect radiation properties for its designated eye. This copying strategy enables precise separate measurement while simplifying manufacturing through standardization and replication of proven detector designs rather than requiring unique custom components
3Stability of the object's composition
If real-time adjustment of display properties is implemented, then image quality stability is improved, but the system complexity and energy consumption increase
Solution Approach 1:
The sensor unit provides real-time feedback on the actual radiation properties of displayed sub-images by detecting and measuring them. This feedback enables the display system to automatically adjust and maintain optimal image quality and stability without requiring continuous high-energy operations, as adjustments are made only when deviations are detected
Solution Approach 2:
The calibration and optimization system uses the display system's own radiation output as the measurement source, eliminating the need for external calibration equipment or additional illumination sources. The system self-calibrates by detecting its own displayed sub-images, reducing overall system complexity and energy consumption while maintaining stable display properties
