Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical image stabilization is implemented through relative movement between image sensor, array, and beam deflection device, then image stabilization quality is improved, but device complexity increases
Solution Approach 1:
The patent combines optical image stabilization (through relative movement of image sensor, array, and beam deflection device) with electronic image stabilization (through electronic image stabilizer that compensates for channel deviations) into a unified stabilization system. This merging of optical and electronic stabilization mechanisms allows the system to achieve high image stabilization quality while managing the complexity through integrated control and processing.
2Manufacturing precision
If electronic image stabilization compensates for channel deviations, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The electronic image stabilizer operates as a feedback mechanism that detects and compensates for deviations between optical channels. By continuously monitoring channel performance and applying corrective processing, the system improves manufacturing precision without requiring complex mechanical adjustments, thus managing device complexity through intelligent control.
3Volume of moving object
If compact design is achieved through shared components, then volume is reduced, but manufacturing precision becomes more difficult to maintain
Solution Approach 1:
The patent implements a multi-functional design where the image sensor, array, and beam deflection device serve multiple purposes: they are used for both capturing images and for optical image stabilization through relative movement. This universality allows the system to achieve compact design by reducing redundant components while maintaining manufacturing precision through integrated design and shared calibration processes.
