Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image data is transferred via wireless network, then system portability and ease of operation are improved, but transfer time and analysis wait time increase significantly
Solution Approach 1:
The system dynamically adapts the data transfer method based on real-time conditions. The determining means selects between shared memory, wired network, or wireless network transmission based on connection availability and data volume, making the system flexible rather than static in its approach to data transfer.
Solution Approach 2:
The system changes key parameters including data compression ratio, decimation level, and transfer protocol based on the selected transmission method. For wireless transmission, parameters are adjusted to compress data more aggressively or reduce resolution, thereby reducing transfer time while maintaining acceptable image quality for analysis.
2Loss of time
If image data is transferred via wired network, then transfer speed and analysis time are improved, but system complexity and connection requirements increase
Solution Approach 1:
The system is designed to support multiple transmission methods (shared memory, wired network, wireless network) through a single unified architecture. The determining means automatically selects the appropriate method based on current system state, making the system universally compatible with different connection scenarios without requiring separate dedicated systems.
Solution Approach 2:
The determining means acts as an intermediary that manages the complexity of multiple connection schemes. It abstracts the complexity from the user by automatically selecting and managing the appropriate transmission method, while the image processing and analysis components remain unchanged regardless of the transmission path used.
3Loss of time
If data compression and decimation are applied for wireless transfer, then transfer time is reduced, but image data quality and analysis precision may deteriorate
Solution Approach 1:
The system applies partial compression and decimation only to the extent necessary for wireless transmission feasibility. Rather than fully compressing all data, it selectively reduces data volume through controlled decimation of image frames or regions, maintaining sufficient quality for diagnostic analysis while achieving acceptable transfer times.
Solution Approach 2:
The system dynamically adjusts compression parameters and decimation levels based on the specific transmission conditions and image characteristics. For critical diagnostic regions, higher quality is preserved, while less critical areas undergo greater compression, optimizing the balance between transfer efficiency and analysis precision.

AI summary
A radiographic image capturing system is described. If a hardware processor determines that an image processor and an image analyzing unit are capable of sharing image data via an identical memory, the image processor stores image data in the memory and the image analyzing unit analyzes the image data with reference to the memory. If the hardware processor determines that the image processor and the image analyzing unit can send and receive the data via a wired network, the image processor transfers the data to the image analyzing unit, and the image analyzing unit analyzes the data. If the hardware processor determines that the image processor and the image analyzing unit can send and receive the data via a wireless network, the image processor compresses the data or decimates partial data and transfers the data to the image analyzing unit, and the image analyzing unit decompresses and analyzes the data.
