Connecting Board Layout for Overlapping Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in miniaturization due to the need for large transverse spaces to avoid interference between components like antenna elastic sheets and other components, which occupy significant space and hinder compact internal layouts.
Innovation Solution
An electronic component connecting structure is designed where components are placed on both sides of a connecting board, with perpendicular projections overlapping or maintaining a threshold distance, utilizing both transverse and longitudinal spaces to minimize interference and reduce transverse space occupation.

Engineering Contradiction Analysis
1Reliability
If a specific avoidance space is provided between the antenna elastic sheet and other components, then mutual interference between components is avoided, but the transverse space occupied increases and the internal layout becomes less compact
Solution Approach 1:
The patent applies dimensionality change by transitioning from a two-dimensional transverse layout to a three-dimensional stacked layout. Components are arranged on opposite sides of a circuit board in the thickness direction, allowing their projections to overlap in the transverse plane while maintaining physical separation through the board thickness. This resolves the contradiction by eliminating the need for transverse avoidance space while ensuring component interference avoidance through vertical separation.
2Area of stationary object
If components are arranged to overlap in projection, then transverse space is reduced, but the distance between components must be maintained to prevent interference
Solution Approach 1:
The patent utilizes the thickness direction (z-axis) as an additional dimension to resolve the spatial conflict. By positioning components on opposite sides of the circuit board separated by the board thickness, the design achieves projection overlap in the transverse plane while maintaining adequate physical distance in the vertical direction, thus preventing interference.
Solution Approach 2:
The circuit board serves as an intermediary structure that physically separates components positioned on its opposite sides. The board's thickness provides the necessary separation distance to prevent interference between components whose projections overlap in the transverse plane, while still allowing compact transverse layout.

AI summary
An connecting structure includes a connecting board, a first component connecting to one side of the connecting board; and a second component connecting to the other side of the connecting board. A perpendicular projection of the first component on a preset plane overlaps a perpendicular projection of the second component on the preset plane, and the preset plane is parallel to a plane on which one side of the connecting board is located. A padding element is disposed between the first component and the connecting board. The structure can reduce occupation of transverse space inside the electronic device and help make a profile of the electronic device smaller.
