1Area of stationary object
If connectors are disposed on the printed circuit board in conventional manner, then electrical connection is achieved, but space utilization is insufficient and component integration is limited
Solution Approach 1:
The connector is nested within an opening formed in the printed circuit board. The opening penetrates through the board, allowing the connector to be disposed inside the board structure rather than on its surface, thereby enabling additional components to be superposed on the same area and improving space utilization.
Solution Approach 2:
The connector arrangement transitions from a two-dimensional surface mounting approach to a three-dimensional configuration by utilizing the depth dimension through the opening. This allows components to be stacked vertically, with additional components placed on top of the connector within the opening, effectively using the Z-axis dimension to increase component density.

If larger display is adopted to output larger screen, then user convenience is improved, but portability is limited
Solution Approach 1:
The patent utilizes the thickness dimension of the printed circuit board to accommodate connectors within openings, freeing up surface area for larger display configurations. This vertical space utilization enables larger displays without proportionally increasing the device's footprint, thus improving the balance between display area and portability.
