Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution images are transmitted over bandwidth-limited communication links, then image quality is improved, but transmission speed deteriorates
Solution Approach 1:
The patent segments the high-resolution image into multiple lower-resolution sub-images or image blocks that can be transmitted separately over the bandwidth-limited communication link. This segmentation allows the large high-resolution image to be broken down into smaller data units that fit within the bandwidth constraints while maintaining the overall image quality when reassembled at the receiving end.
Solution Approach 2:
The patent transforms the transmission problem from a single high-resolution image in one dimension to multiple lower-resolution images across multiple dimensions (time, spatial distribution). By transmitting multiple sub-images sequentially or in parallel across different time slots or communication channels, the system achieves both high final image quality and feasible transmission speed within bandwidth limits.
2Area of stationary object
If multiple images are captured and synthetically combined to cover large areas, then area coverage is improved, but device complexity deteriorates
Solution Approach 1:
The patent divides the large area coverage task into multiple smaller image captures, with each image covering a specific sub-area. These segmented image captures are then synthetically combined through image fusion algorithms to reconstruct the complete large-area view, avoiding the need for a single complex wide-angle lens system.
Solution Approach 2:
The patent merges multiple individual image captures into a single composite image that covers a larger area than any single capture could provide. By combining the strengths of multiple images taken from slightly different positions or angles, the system achieves extensive area coverage without requiring an overly complex imaging device.
3Measurement precision
If multiple images are captured and synthetically combined to achieve high resolution, then resolution is improved, but loss of time deteriorates
Solution Approach 1:
The patent performs preliminary actions by capturing multiple images simultaneously or in rapid succession with precise timing and positioning information recorded during capture. This preliminary data collection phase is optimized so that the subsequent synthetic combination process can efficiently reconstruct high-resolution images without excessive processing delays.
Solution Approach 2:
The patent creates multiple copies or representations of the scene from different perspectives or focal lengths, then uses these copies to synthesize a high-resolution composite image. By having pre-captured image copies available, the system can perform resolution enhancement through image fusion rather than requiring lengthy single-image processing.
