Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion sensors are configured on multiple camera modules to enable optical image stabilization, then photographing performance is improved, but production cost increases
Solution Approach 1:
The patent makes a single motion sensor serve multiple camera modules by implementing a sharing mechanism where the sensor's detection results are utilized by multiple lens driving mechanisms. The controller allocates the motion sensor's data to different camera modules based on their photographing states, enabling one sensor to perform the function of multiple sensors and thereby reducing production costs while maintaining photographing performance.
2Reliability
If motion sensors are configured on multiple camera modules, then optical image stabilization is enabled for each module, but structural space is consumed
Solution Approach 1:
The patent merges the motion sensing function for multiple camera modules into a single sensor unit. Instead of distributing separate sensors to each camera module, the system combines the sensing resources centrally and shares them across modules through coordinated control, thereby reducing the total spatial footprint while preserving stabilization capabilities for all modules.
3Reliability
If multiple motion sensors are installed in the mobile terminal, then each camera module can independently perform image stabilization, but the terminal becomes heavier
Solution Approach 1:
The patent enables a single motion sensor to provide stabilization support for multiple camera modules through a sharing architecture. The sensor detects motion affecting multiple modules, and the controller distributes this information to appropriate lens driving mechanisms, allowing one sensor to replace what would traditionally require multiple sensors, thereby reducing terminal weight while maintaining stabilization performance.
4Reliability
If multiple motion sensors are installed in the mobile terminal, then optical image stabilization is achieved for multiple camera modules, but the terminal becomes more complex
Solution Approach 1:
The patent merges the sensing and control architecture into a unified system where a single motion sensor feeds data to a central controller that manages multiple camera modules. This consolidated approach reduces the complexity of having multiple independent sensor systems, as the shared architecture simplifies wiring, power management, and data processing while still enabling stabilization for all modules.
