Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mechanical FMC stabilization system is used, then image stabilization performance is improved, but camera body size and mass inertia increase
Solution Approach 1:
The patent replaces traditional mechanical FMC stabilization components with a solid-state actuator that directly moves the sensor along the flight direction. This substitution eliminates complex mechanical linkages, gears, and moving mirrors, achieving image stabilization through direct sensor displacement controlled by solid-state actuators, thereby reducing camera body size while maintaining stabilization performance
Solution Approach 2:
The patent extracts and eliminates unnecessary mechanical components from the traditional FMC system. By removing intermediate mechanical transmission elements and retaining only the essential sensor displacement function, the design achieves compact dimensions while preserving the core image stabilization capability
2Reliability
If traditional mechanical FMC components are used, then stabilization function is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple separate mechanical FMC components into a single integrated assembly where the sensor, solid-state actuators, and support structure form a unified system. This consolidation reduces the number of discrete parts, simplifies the overall structure, and eliminates the need for complex mechanical linkages while maintaining the stabilization function
Solution Approach 2:
The solid-state actuators serve multiple functions: they provide precise positional control of the sensor, enable FMC stabilization along the flight direction, and integrate with the camera's existing mounting and support structures. This multi-functionality reduces the need for dedicated components, thereby simplifying the overall device complexity
