Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The adapter is segmented into distinct functional modules: the housing, the embedded circuit board, and the conductive terminals. Each module is independently manufactured and then assembled through simple insertion operations. This segmentation enables detachable connections while keeping individual component complexity low.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The circuit board serves as an intermediary element that facilitates detachable connections. It is embedded within the housing through precision-molded interfaces, allowing the adapter to be easily assembled and disassembled while maintaining stable electrical connections.
