Solution Approach 1:

The insulator is segmented by providing holes extending from the external space toward the core, creating multiple heat dissipation pathways. This segmentation allows heat to be efficiently removed from the core region through the insulator structure without compromising electrical insulation, thereby resolving the contradiction between operational stability and core heat dissipation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insulator serves as an intermediary structure that performs dual functions: maintaining electrical insulation and facilitating heat dissipation. By incorporating heat dissipation holes within the insulator, the design enables the insulator to mediate between the core heat generation and external heat dissipation requirements, improving both reliability and thermal management.
