Here’s PatSnap Eureka !
Summary
Problems
Magnetic devices in high-power applications face challenges with volume, weight, and loss due to the need for customized core designs, which complicates product development and manufacturing.
Innovation solutions
A magnetic device core structure integrating inductor and transformer functions, featuring a first and second magnetic cover, winding columns, and a common side column, allowing for efficient power handling and reduced size, suitable for low-voltage high-current applications, with adjustable winding configurations to maintain constant PCB layers and minimize heat dissipation and cost issues.

Specific contradictions:
General conflict description:
Principle concept:
If customized core design is used for high power supply, then power handling capability is improved, but device complexity and manufacturing difficulty increase
Why choose this principle:
The magnetic core structure integrates both inductor and transformer functions within a single unified design. The core includes winding columns that can accommodate both inductor windings and transformer windings (primary and secondary), allowing one core structure to perform multiple functions that traditionally required separate components. This multi-functionality maintains high power handling capability while reducing design complexity and standardizing the core structure.
Principle concept:
If customized core design is used for high power supply, then power handling capability is improved, but manufacturing cost and difficulty increase
Why choose this principle:
The standardized core structure with integrated inductor and transformer columns enables a single manufacturing process to produce cores suitable for both inductor and transformer applications. This universality allows manufacturers to use the same tooling, assembly procedures, and quality control processes for different power products, significantly reducing manufacturing complexity and cost while maintaining high power capability.

Abstract
A magnetic dev ice includes a core structure, at least one inductor winding and at least two transformer windings. The core structure includes at least one inductor column and at least two transformer columns. The at least one inductor winding respectively winds around the at least one inductor column. The at least two transformer windings, wind around the at least two transformer columns respectively, and the transformer winding includes primary winding and secondary winding. Wherein the magnetic flax directions on adjacent transformer columns are opposite to each other when providing a current in the corresponding primary windings simultaneously.
