Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional rigid coil structure is used, then the coil maintains structural stability, but it cannot properly contact with curved body surfaces and achieve effective magnetic field focusing
Solution Approach 1:
The patent applies this principle by using a flexible hollow tube to encase the coil bundle, allowing the coil to conform to curved body surfaces while maintaining its internal structure. The flexible tube enables the rigid coil bundle to adapt to irregular geometries without compromising structural integrity.
Solution Approach 2:
The patent implements dynamics by making the coil structure flexible and adaptable rather than rigid and fixed. The coil can dynamically adjust its shape to match the target area contours, enabling proper contact while maintaining structural stability through the flexible enclosure.
2Ease of manufacture
If conventional copper materials are used in the coil, then the coil is easy to manufacture, but impedance causes heat generation and reduced treatment efficiency
Solution Approach 1:
The patent applies composite materials by combining oxygen-free copper strands with a flexible hollow tube enclosure. The oxygen-free copper provides low impedance and high electrical conductivity, while the flexible tube provides structural support and adaptability, creating a composite structure that addresses both manufacturing ease and energy loss issues.
Solution Approach 2:
The patent implements parameter changes by specifying oxygen-free copper with high purity (99.99% or higher) to minimize impedance and heat generation. This material parameter change significantly reduces energy loss while maintaining ease of manufacture through standard copper fabrication processes.
3Adaptability or versatility
If the coil structure is made rigid for stability, then manufacturing is simplified, but the coil cannot be fitted into curves of various body portions
Solution Approach 1:
The patent uses a flexible hollow tube to encase the coil bundle, providing the necessary flexibility to conform to various body curves and surfaces. This flexible enclosure allows the coil to adapt to different anatomical geometries without requiring complex flexible coil designs.
Solution Approach 2:
The patent applies segmentation by dividing the coil into a coil bundle (electrical component) and a flexible hollow tube (structural component). This segmentation allows each component to be optimized independently - the coil bundle for electrical performance and the tube for flexibility and adaptability.
