Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If array light field imaging system is used to improve imaging performance, then imaging performance is improved, but volume and weight increase
Solution Approach 1:
The imaging system is divided into multiple independent image sensors arranged in an array, where each sensor captures a portion of the light field. This segmentation allows the system to achieve comprehensive light field imaging performance while distributing the volume across multiple smaller units rather than requiring a single large sensor.
Solution Approach 2:
Multiple image sensors are integrated into a compact array configuration where sensors are closely packed and interconnected through flexible circuits. The sensors, conductors, and support structures are nested together in a space-efficient manner, maximizing imaging performance within minimized volume.
2Measurement precision
If array light field imaging system is used to improve imaging performance, then imaging performance is improved, but weight increases
Solution Approach 1:
The image sensors are mounted on flexible substrates with thin flexible conductors connecting them. This flexible film-based structure significantly reduces the weight compared to traditional rigid circuit boards and mounting structures, while maintaining electrical connectivity and mechanical stability of the sensor array.
Solution Approach 2:
The system employs composite construction combining lightweight sensor elements with flexible polymer substrates and thin conductor traces. This composite approach minimizes overall weight while preserving the structural integrity and imaging performance of the array configuration.
3Stability of the object's composition
If rigid morphology design is used to ensure structural stability, then structural stability is ensured, but adaptability and portability are compromised
Solution Approach 1:
The sensor array is mounted on flexible substrates that can dynamically change shape and conform to different surfaces. This dynamic flexibility allows the rigid image sensors to maintain their stability while the overall array adapts to various geometries and mounting configurations, achieving both structural stability and adaptability.
Solution Approach 2:
The flexible substrate allows the array to change its physical parameters such as curvature, area, and configuration. By changing these geometric parameters, the system can adapt to different application scenarios while the rigid sensors themselves maintain their operational stability and imaging performance.
