Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inductive components for high-current applications face challenges in reducing self-inductance and material usage while maintaining electromagnetic properties, particularly in the medium-frequency range.
Innovation Solution
The design incorporates a winding section that extends circumferentially around the core along a circular arc with a center point angle less than 360°, reducing the length of the winding section per unit of enclosed volume, and utilizes a core with a semicircular cross-section and outer core for enhanced magnetic flux coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a rectangular conductor bracket is used to surround the core, then the inductive component can be manufactured with simple geometry, but the length of the winding section per unit of enclosed volume is increased
Solution Approach 1:
The patent applies curvature by changing the conductor bracket geometry from rectangular to circular arc shape. The winding section extends along a circular arc with center point angle b of 45°≤b<360°, creating a curved configuration that reduces the winding section length for the same enclosed volume compared to rectangular geometry.
2Productivity
If the winding section extends along a circular arc with center point angle b of 45°≤b<360°, then the length of the winding section per unit of enclosed volume is reduced, but the manufacturing complexity increases
Solution Approach 1:
The patent optimizes the center point angle parameter b to be in the range 45°≤b<360°, particularly 90°≤b≤180°, to achieve the best compromise between productivity (inductance per volume) and manufacturability. This parameter optimization allows the circular arc geometry to provide compact design while remaining feasible for standard manufacturing processes.
3Reliability
If the core has a semicircular cross-section, then the magnetic flux coverage is enhanced and inductance per unit volume increases, but the manufacturing precision requirements increase
Solution Approach 1:
The patent merges the core and conductor bracket into an integrated assembly where the semicircular core fits within the circular arc conductor bracket. This integration ensures proper alignment and positioning, reducing the need for high manufacturing precision in individual components while achieving enhanced magnetic flux coverage through the optimized semicircular geometry.
