Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If time data is generated separately by injection device and imaging device, then each device can operate independently, but the time gap between devices becomes large and accurate correlation is not possible
Solution Approach 1:
The patent introduces a sound detection device as an intermediary that captures sound signals from the imaging device and transmits them to the injection device. This intermediary enables time synchronization between the two devices without requiring direct time data sharing or complex integration infrastructure, resolving the contradiction by maintaining independent operation while achieving accurate time correlation through acoustic signal mediation
2Measurement precision
If NTP servers are integrated, then time data can be synchronized accurately, but few medical institutions have implemented this integration
Solution Approach 1:
Instead of implementing complex NTP server integration, the patent uses a sound detection device as a simple intermediary that naturally synchronizes time data. The sound signals from the imaging device serve as a universal time reference that the injection device can capture and correlate, achieving accurate time synchronization without requiring complex network time protocol infrastructure or deep system integration
Solution Approach 2:
The patent replaces the electronic/time-based NTP synchronization system with an acoustic-based synchronization approach. By detecting sound signals and converting them into time-correlated data, the system achieves synchronization without relying on complex electronic time servers, reducing implementation complexity while maintaining precision
3Ease of operation
If injection start time and imaging start time are not synchronized, then device operation is simple, but accurate correlation of injection history data and imaging timing is not possible
Solution Approach 1:
The sound detection device acts as an intermediary that captures acoustic signals from the imaging device and translates them into time-correlated data for the injection device. This preserves the temporal relationship between injection and imaging events without requiring complex synchronization mechanisms, thus maintaining simple operation while preventing information loss in time correlation
