Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If raw data is transmitted without backup redundancy, then device complexity is reduced, but data reliability deteriorates due to potential data loss from interference or hardware failures
Solution Approach 1:
The patent implements preliminary action by storing raw data in backup memories on the rotational part of the gantry before transmission occurs. This advance preparation ensures that if data loss occurs during transmission, the original data is already preserved and can be retransmitted without requiring a repeat scan, thus improving reliability without significantly increasing overall system complexity.
Solution Approach 2:
The patent applies the copying principle by creating duplicate copies of raw data in backup memories located on the rotational part. These copies serve as redundant storage that can be used for retransmission if the original transmission fails, thereby enhancing data reliability while maintaining a relatively simple system architecture through efficient use of existing memory resources.
2Manufacturing precision
If data is retransmitted from backup memories, then image quality is improved by correcting data errors, but loss of time occurs due to the additional data handling process
Solution Approach 1:
The system implements self-service by automatically detecting data errors during transmission and initiating retransmission from backup memories without requiring external intervention or manual correction. This automated process improves image reconstruction quality by ensuring data accuracy while minimizing time loss through efficient error handling that occurs seamlessly during the scanning workflow.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors transmitted data for errors and automatically triggers retransmission from backup memories when data quality issues are detected. This closed-loop approach ensures high image reconstruction quality by correcting errors in real-time while managing processing time efficiently through intelligent error detection and selective retransmission.
3Productivity
If continuous scanning is maintained despite power supply issues, then productivity is improved by avoiding re-scans, but use of energy increases to maintain scanning continuity
Solution Approach 1:
The patent applies preliminary action by storing raw data in backup memories during the scanning process before power supply issues can disrupt operation. This advance data preservation allows the system to maintain scanning continuity even during power fluctuations, improving productivity by avoiding the need to abort and restart scans, while managing energy consumption through efficient memory utilization.
Solution Approach 2:
The system implements beforehand cushioning by creating redundant data storage in backup memories that acts as a buffer against power supply disruptions. This protective measure enables continuous scanning operation despite power issues, enhancing productivity by preventing scan interruptions, while the energy cost is offset by avoiding the much higher energy consumption that would result from repeated re-scanning of the same subject.
