Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance information is generated using a separate distance sensor, then distance measurement capability is improved, but device complexity and calibration requirements increase
Solution Approach 1:
The patent combines the distance measurement function with the imaging device by integrating a distance sensor into the imaging device housing, allowing both imaging and distance measurement to be performed by a single integrated device rather than separate components
Solution Approach 2:
The imaging device is designed to perform multiple functions including both image capture and distance measurement, eliminating the need for separate dedicated distance sensing equipment and reducing overall system complexity
2Manufacturing precision
If calibration work is performed before imaging, then image combination accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The patent performs calibration work automatically in advance during device setup or manufacturing, storing the calibration results for later use during image combination operations, thereby eliminating the need for manual calibration before each imaging session
Solution Approach 2:
The system performs automatic calibration using its own integrated sensors and processing capabilities without requiring external calibration equipment or manual intervention, enabling the device to self-calibrate and store results for future operations
3Adaptability or versatility
If chroma-key combination is used, then background separation capability is improved, but operational complexity and post-processing requirements increase
Solution Approach 1:
The patent introduces distance information as an intermediary parameter that facilitates background separation by providing depth data, enabling more accurate subject-background differentiation without relying solely on color-based chroma-key methods
Solution Approach 2:
The system transitions from relying exclusively on color parameters for background separation to incorporating distance/depth parameters, allowing for more versatile and accurate image combination by using multiple parameters including both color and spatial information
