Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image sensor uses fixed initial setting values, then the device complexity is reduced, but the adaptability to changing image signal processing and shooting environments deteriorates
Solution Approach 1:
The patent implements dynamic setting adjustment by allowing the image sensor to change its operating parameters in real-time based on detected shooting conditions. The system transitions from fixed initial settings to dynamic reconfiguration, where settings are automatically adjusted according to environmental factors like lighting conditions, enabling the sensor to adapt to varying requirements without manual intervention.
Solution Approach 2:
The patent changes physical or operational parameters of the image sensor by modifying setting values such as exposure time, gain, and other operational parameters. This allows the sensor to optimize its performance for different shooting environments by adjusting these parameters dynamically, resolving the contradiction between adaptability and complexity through automated parameter modification.
2Adaptability or versatility
If the setting values are changed frequently to adapt to different environments, then the adaptability is improved, but the time required for setting changes increases
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple setting configurations that can be quickly switched between. The system prepares advance settings for different shooting scenarios and enables rapid transition between these pre-configured states, reducing the time required for setting changes while maintaining high adaptability to different environments.
Solution Approach 2:
The patent uses copying by creating replicated setting configurations that can be instantiated quickly. Instead of modifying settings from scratch, the system copies and reuses pre-optimized setting templates for different shooting conditions, enabling fast adaptation without time-consuming recalibration processes.
3Adaptability or versatility
If the initial setting values are modified, then the adaptability to different shooting environments is improved, but the reliability of the original configuration deteriorates
Solution Approach 1:
The patent segments the setting configuration into a stable initial configuration and adjustable operational parameters. The initial settings remain reliable and unchanged, while only specific operational parameters are modified during operation. This segmentation allows the system to maintain the reliability of the base configuration while achieving adaptability through parameter adjustment.
Solution Approach 2:
The patent introduces an intermediary layer between the fixed initial settings and the operational parameters. This intermediary mechanism allows for controlled modification of settings while preserving the integrity of the original configuration. The intermediary acts as a buffer that enables adaptive changes without directly modifying the reliable initial settings, thus maintaining both adaptability and reliability.
