Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed signal processing channels are used in the control computer, then the system structure is simple, but the configurability and adaptability to different MRI systems are poor
Solution Approach 1:
The patent implements a universal control computer architecture that can handle multiple signal types (RF signals, magnetic field gradient signals, feedback signals) through a unified processing platform. The control module is designed to process various signal types through common signal processing channels, allowing the same hardware to adapt to different MRI system configurations and requirements, thereby achieving multi-functionality and improved configurability.
2Adaptability or versatility
If multiple signal types are processed through fixed channels, then signal processing is straightforward, but the system cannot be easily reconfigured for different MRI applications
Solution Approach 1:
The patent employs dynamic signal processing channels where the processing path is not fixed but can be dynamically configured based on the type of signal being processed and the specific MRI application requirements. The control module can dynamically route different signal types (RF, gradient, feedback) through appropriate processing paths, enabling the system to adapt to various MRI applications without requiring dedicated fixed channels for each signal type.
