Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors of the same shutter type are used, then shutter synchronization can be achieved, but device complexity and cost increase due to requiring identical sensor types
Solution Approach 1:
The patent changes the timing parameters (synchronization signal delay and exposure delay) of sensors with different shutter types to achieve synchronized exposure. By dynamically adjusting these delay parameters, the system enables shutter synchronization between sensors of different types without requiring identical sensor configurations, thus resolving the contradiction between synchronization reliability and sensor type flexibility.
2Adaptability or versatility
If sensors of different shutter types are used, then device complexity and cost are reduced, but shutter synchronization cannot be achieved leading to picture shifting
Solution Approach 1:
The patent introduces dynamic adjustment of synchronization signal delay and exposure delay parameters to adapt to different shutter types. This dynamic timing adjustment mechanism allows the system to maintain shutter synchronization when using sensors of different types, converting a static limitation into a dynamically solvable problem and eliminating picture shifting while preserving sensor type flexibility.
3Reliability
If synchronization delay adjustment is implemented, then shutter synchronization is achieved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent implements a universal delay adjustment mechanism that can handle multiple sensor types and configurations through a single control system. The synchronization control unit is designed to universally manage different shutter types by adjusting timing parameters, reducing the need for separate control mechanisms for each sensor type and thereby limiting the increase in device complexity.
