Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed diameter coils are used, then the structure is simple and reliable, but the adaptability to different applications requiring varying magnetic field strengths is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed diameter coil into a variable diameter coil through the introduction of movable hubs and supports. The inner hub with inner supports and outer hub with outer supports can move relative to each other, allowing the coil diameter to be adjusted dynamically. This enables the same coil structure to adapt to different applications requiring varying magnetic field strengths, directly resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent segments the coil structure into multiple independent components: inner winding layer, outer winding layer, inner hub, outer hub, inner supports, and outer supports. This segmentation allows each component to move and adjust independently, enabling variable diameter functionality while maintaining the electromagnetic performance of the complete coil structure. The segmented design provides adaptability without requiring complete redesign for each application.
2Adaptability or versatility
If variable diameter mechanism is added, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The patent achieves universality by designing a multi-functional coil structure that can serve multiple purposes: generating magnetic fields at different diameters, adjusting to different application requirements, and maintaining electromagnetic performance across variable configurations. The same basic structure with movable hubs and supports provides both fixed and variable diameter capabilities, reducing the need for multiple separate coil designs and offsetting the increased component count with multi-functionality.
