Engineering Contradiction Analysis
1Device complexity
If a pure software algorithm is used to correct motion jitter, then device complexity is reduced, but photograph sharpness deteriorates under pressure
Solution Approach 1:
A pressure sensing module is introduced as an intermediary component between the user's press operation and the camera system. This module detects pressure magnitude and direction, providing data that enables the processor to calculate deformation patterns and determine optimal viewfinding moments, thereby maintaining photograph sharpness under pressure without requiring complex mechanical stabilization systems
Solution Approach 2:
The system performs preliminary detection of pressure characteristics before the actual photograph is captured. By detecting the press operation, collecting pressure sensing data, and calculating the deformation pattern in advance, the system determines the optimal viewfinding moment before image capture, allowing proactive compensation for pressure-induced displacement
2Manufacturing precision
If a multi-axis sensor is used to correct motion jitter, then photograph sharpness is improved, but device complexity increases
Solution Approach 1:
The invention extracts only the essential pressure information (magnitude and direction) needed for compensation using a simple pressure sensing module, rather than employing a complex multi-axis sensor system. This extracted pressure data is sufficient to calculate deformation patterns and determine optimal capture moments, achieving sharpness improvement without the complexity of multi-axis sensing hardware
Solution Approach 2:
The patent replaces mechanical stabilization systems (multi-axis sensors and associated mechanical correction mechanisms) with a software-based solution driven by pressure sensing data. The processor uses the pressure information to calculate deformation patterns and timing, substituting mechanical complexity with computational processing to achieve the same sharpness improvement
3Manufacturing precision
If pressure sensing module is added to detect press operation, then photograph sharpness is improved, but device complexity increases
Solution Approach 1:
The pressure sensing module serves multiple functions: it detects the press operation timing, measures pressure magnitude, determines pressure direction, and provides data for deformation pattern calculation. This multi-functionality justifies the addition of the component, as it replaces what would otherwise require multiple separate sensors and processing systems
Solution Approach 2:
The system changes from monitoring only binary press/don't-press states to continuously monitoring pressure magnitude and direction parameters. This parameter enrichment allows the processor to calculate deformation patterns and determine optimal viewfinding moments, improving photograph sharpness through enhanced pressure characterization
