Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If higher resolution and higher frame rate are implemented for multispectral imaging, then imaging performance is improved, but data processing volume per unit time increases
Solution Approach 1:
The patent applies preliminary action by performing compression coding on multispectral image data immediately after acquisition, before the data enters communication or memory interfaces. This preprocessing step reduces the data volume in advance, preventing the interface load from increasing proportionally with improved imaging performance.
2Productivity
If data processing volume per unit time increases, then bandwidth and transfer speed of communication interface must increase, but costs increase
Solution Approach 1:
The patent changes the parameter of data representation by applying compression coding algorithms that transform the original multispectral data into a more compact form. This parameter change reduces the effective data volume that needs to be transmitted or stored, thereby maintaining high processing speeds without requiring proportionally higher bandwidth or transfer speed infrastructure.
3Productivity
If data processing volume per unit time increases, then bandwidth and transfer speed of memory interface must increase, but costs increase
Solution Approach 1:
The patent performs compression coding as a preliminary action before data enters memory interfaces, reducing the data volume that needs to be written to or read from memory. This prevents the memory interface load from increasing linearly with improved imaging performance, thereby avoiding the need for more expensive high-bandwidth memory interfaces.
