Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic modules face challenges in effectively transmitting high-frequency signals due to high resistance at the input and output ends of coils, which hinders efficient signal transmission.
Innovation Solution
A magnetic module design with one coil having four groups of enameled wires and the other coil having one group of enameled wires, optimized for winding distribution, to reduce resistance and enhance high-frequency signal transmission capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coil winding with two wires per input/output end is used, then manufacturing is simpler, but resistance is high and high-frequency signal transmission is poor
Solution Approach 1:
The coil winding is segmented into multiple independent wire groups (first group, second group, third group, fourth group) instead of using traditional two-wire configuration. Each group is wound independently around the magnetic core, allowing optimization of electrical characteristics for high-frequency signal transmission while maintaining manageable manufacturing complexity through modular assembly.
2Reliability
If more enameled wires are used in coil winding, then resistance decreases and signal transmission improves, but manufacturing complexity increases
Solution Approach 1:
The multi-wire coil is divided into four separate wire groups that can be prepared and wound independently, then assembled together. This segmentation allows for standardized manufacturing processes for each group while achieving the low resistance and high signal transmission effectiveness required for 25 Gbps capability.
Solution Approach 2:
Multiple enameled wire groups are combined in parallel configuration around the magnetic core to reduce overall resistance. The first, second, third, and fourth groups are all wound around the same magnetic core, creating a merged structure that achieves superior electrical performance while distributing the manufacturing complexity across identical modular units.
