Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is compressed for wireless transmission in M-mode inspection, then communication efficiency is improved, but image quality deteriorates due to seams and unevenness
Solution Approach 1:
The system dynamically adjusts the compression ratio based on the inspection mode. In M-mode inspection, the compression ratio is set to a first value optimized for temporal continuity, while in B-mode inspection, it is set to a second value optimized for spatial resolution. This dynamic adaptation resolves the contradiction by optimizing compression parameters for each specific inspection scenario.
Solution Approach 2:
The system changes the compression ratio parameter according to the inspection mode. By setting different compression ratios (first value for M-mode, second value for B-mode), the system maintains image quality appropriate for each inspection type while maximizing communication efficiency.
2Quantity of substance
If compression ratio is increased to reduce data transmission size, then communication bandwidth requirement is reduced, but image quality and continuity deteriorate
Solution Approach 1:
The system applies different compression ratios tailored to specific inspection modes. M-mode uses a compression ratio optimized for temporal continuity (first value), while B-mode uses a compression ratio optimized for spatial detail (second value). This localized optimization ensures each mode receives appropriate compression without compromising its specific quality requirements.
Solution Approach 2:
The compression ratio is dynamically adjusted based on the inspection mode being performed. The system switches between first and second compression ratios according to whether M-mode or B-mode inspection is active, ensuring optimal balance between data size reduction and quality maintenance for each scenario.
3Ease of operation
If wireless transmission is implemented to improve mobility, then operability is improved, but image quality control becomes more difficult
Solution Approach 1:
The system changes compression parameters based on inspection mode to maintain image quality control in wireless operation. By adjusting the compression ratio according to whether M-mode or B-mode is active, the system compensates for the challenges of wireless transmission and maintains appropriate quality levels.
Solution Approach 2:
The system uses feedback from the inspection mode setting to adjust compression parameters. The image display device communicates the inspection mode to the ultrasound probe, which then adjusts its compression ratio accordingly, creating a closed-loop control system that maintains image quality despite wireless transmission constraints.
