Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic focus function is used to adapt to different ambient environments, then image-shooting adaptability is improved, but focus stability deteriorates due to environmental changes and object variations
Solution Approach 1:
The system dynamically switches between manual and automatic focus modes based on operational requirements. The switching unit allows transition from static manual focus (high stability) to dynamic automatic focus (high adaptability), resolving the contradiction by making the focus control mechanism itself dynamic rather than fixed.
Solution Approach 2:
The controller adjusts focus parameters automatically based on sensing information from the sensor, changing focal length and other focus-related parameters adaptively. This allows the system to maintain focus stability in automatic mode by continuously optimizing parameters based on environmental feedback.
2Device complexity
If built-in microphone is used for sound reception, then device integration is improved, but sound-receiving effectiveness deteriorates in different ambient environments and positions
Solution Approach 1:
The sound reception function is segmented into two independent components: the built-in microphone for close-range or fixed-position reception, and the detachable wireless microphone module for flexible remote reception. This segmentation allows each component to be optimized for specific scenarios, maintaining high sound-receiving effectiveness across different environments while keeping the overall device integrated.
Solution Approach 2:
The device achieves multi-functionality in sound reception by supporting both the built-in microphone and the detachable wireless microphone module. This universal design allows the system to adapt to different ambient environments and positions, receiving sound effectively whether the source is close or remote, stationary or mobile.
3Adaptability or versatility
If detachable wireless microphone module is added for flexible sound reception, then sound-receiving adaptability is improved, but device complexity increases
Solution Approach 1:
The wireless microphone module is extracted as a detachable component rather than being permanently integrated. This allows the complexity to be separated: the main device remains relatively simple, while the advanced sound reception capability is available through the optional detachable module, reducing the complexity burden on the core device structure.
