Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple coils are arranged in overlapping configurations to increase signal reception, then imaging efficiency is improved, but coil coupling interference increases
Solution Approach 1:
The coil system is divided into multiple independent coil groups (first coil group, second coil group, third coil group) with each group containing multiple coils arranged in specific directions. This segmentation allows each coil to function independently while collectively improving signal reception efficiency through their overlapping configurations.
Solution Approach 2:
Decoupling structures are introduced as intermediary elements between adjacent coils to eliminate electromagnetic coupling interference. These decoupling structures act as mediators that prevent signal interference while allowing the coils to maintain their overlapping spatial arrangement for improved imaging efficiency.
2Speed
If more coil groups are arranged to receive more signals, then imaging speed increases, but device complexity increases
Solution Approach 1:
Different coil groups are arranged to receive signals from different spatial directions (first direction, second direction, third direction). Each coil group has specific local characteristics optimized for its reception direction, allowing the system to achieve comprehensive signal coverage and improved imaging speed while maintaining manageable structural complexity through functional specialization.
