Electronic Element Connection Layout Using Board Thickness Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic element connection structures occupy excessive transverse space in electronic devices, limiting their downsizing due to the need for avoidance spaces between components like antenna elastic pieces and other elements, which increases the external size of the devices.
Innovation Solution
An electronic element connection structure is designed where the first and second elements are arranged on two sides of a connecting board, with their vertical projections overlapping or being close enough to prevent interference, and maintaining a threshold distance in the perpendicular direction, thereby reducing transverse space occupation by utilizing the thickness direction for avoidance space.

Engineering Contradiction Analysis
1Reliability
If an avoidance space is arranged between the antenna elastic piece and other components, then mutual interference between components is prevented, but the internal layout becomes less compact and the external size increases
Solution Approach 1:
The patent applies dimensionality change by transitioning the avoidance space from the transverse plane to the thickness direction (vertical dimension). Elements are arranged on opposite sides of a connecting board with their projections overlapping on a preset plane, while maintaining a threshold distance in the perpendicular direction. This allows the avoidance space to be formed in the thickness direction rather than occupying transverse space, thereby preventing mutual interference while keeping the device compact in plan view.
2Device complexity
If elements are arranged on the same side of a connecting board, then the connection structure is simple, but sufficient avoidance space cannot be guaranteed to prevent interference
Solution Approach 1:
The patent positions elements on opposite sides of the connecting board (different sides relative to the board thickness direction) while maintaining projection overlap on a preset plane. This spatial arrangement ensures that the distance between elements in the perpendicular direction meets the threshold requirement, providing sufficient avoidance space to prevent interference while maintaining a relatively simple connection structure through the connecting board.
Solution Approach 2:
The patent creates a nested spatial relationship where the projection of one element overlaps with the projection of another element on the preset plane, while the actual elements are separated in the perpendicular direction by the connecting board. This nesting approach allows efficient space utilization in the transverse plane while maintaining necessary separation through the thickness direction.

AI summary
An electronic element connection structure includes a connecting board, a first element, and a second element. The first element is connected to one side of the connecting board, and the second element is connected to an other side of the connecting board. A vertical projection of the first element on a preset plane overlaps with a vertical projection of the second element on the preset plane, where the preset plane is parallel to a plane on which one of the sides of the connecting board is located. A distance between the first element and the second element in a direction perpendicular to the preset plane is greater than or equal to a threshold distance.
