Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MR signals are transmitted via cables or RF connectors, then data can be transmitted from RF coils to MRI device, but noises are added to the signals degrading image quality
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless electromagnetic field-based data transmission system. The RF coil device communicates with the couch device through electromagnetic coupling, eliminating physical cables that introduce noise and degrading signal quality.
Solution Approach 2:
The patent introduces an intermediate wireless transmission medium (electromagnetic field) between the RF coil device and the couch device. This intermediary enables signal transmission without direct physical contact, preventing noise contamination from cable connections.
2Reliability
If complex wiring is used to connect RF coils to MRI device, then data transmission can be achieved, but the mechanical and electronic components become complicated
Solution Approach 1:
The patent replaces the complex mechanical and electrical wiring system with a wireless electromagnetic communication system. The RF coil device and couch device exchange data through electromagnetic coupling, eliminating the need for complex cables, connectors, and associated mechanical structures.
Solution Approach 2:
The patent extracts and removes the complex wiring infrastructure from the MRI system. By eliminating cables, connectors, and associated mechanical components, the system achieves data transmission through wireless electromagnetic fields, significantly simplifying the overall system architecture.
3Reliability
If wireless data transmission is implemented, then noise is minimized and system complexity is reduced, but new transmission mechanisms must be introduced
Solution Approach 1:
The patent implements multi-functionality in the RF coil device and couch device, enabling them to perform both their primary functions (signal detection and patient positioning) and wireless data transmission functions. This integration avoids adding separate dedicated transmission hardware, thereby minimizing the increase in system complexity.
Solution Approach 2:
The patent merges the data transmission function with the existing RF coil device and couch device structures. The wireless transmission components are integrated into these devices, combining multiple functions (signal detection, patient support, and data communication) into unified systems rather than adding separate independent transmission systems.
