Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external devices are connected to the magnetic resonance system via cables, then physical connection and data transmission are established, but the connection becomes disruptive and creates safety risks due to limited space and numerous devices
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The magnetic resonance system and external devices communicate via wireless signals (such as radio frequency communication), eliminating the need for physical cable connections. This substitution removes the safety risks and disruptions caused by cables while maintaining reliable data transmission and synchronization between devices.
2Adaptability or versatility
If manual synchronization is used for contrast medium administration and MR protocol start, then independent device operation is maintained, but productivity decreases due to manual coordination requirements
Solution Approach 1:
The patent implements a feedback mechanism where the magnetic resonance system and external devices exchange synchronization signals wirelessly. The system receives trigger signals from external devices (such as contrast medium injectors) and sends timing information back to coordinate actions. This automated feedback loop enables precise synchronization of contrast medium administration with MR image acquisition sequences, eliminating manual coordination while preserving independent device operation capabilities.
3Ease of operation
If standardized radio interface is implemented, then ease of connection and expandability improve, but device complexity increases due to additional communication protocols
Solution Approach 1:
The patent implements a universal standardized radio interface based on common communication protocols (such as HTTP, TCP/IP, or other standardized wireless communication standards). This single multi-functional interface can communicate with various types of external devices (contrast medium injectors, ECG equipment, monitoring systems) using the same communication framework. The standardized interface includes predefined message formats and protocols that work across different device types, simplifying connections while the modular architecture manages complexity through standardized abstraction layers.
