Reinforced Flexible PCB Layout for Battery Extension Near Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of extending a battery in the direction of a camera while preventing damage to the flexible printed circuit board due to overlapping with other components, particularly when the connector position is changed, is addressed.
Innovation Solution
Incorporating a reinforcement member into the flexible printed circuit board to prevent or reduce damage when it overlaps with other components, allowing the battery to extend in the direction of the camera.

Engineering Contradiction Analysis
1Volume of moving object
If the connector position is changed to extend the battery in the direction of the camera, then the battery can be extended, but the flexible printed circuit board may overlap another electronic component and be damaged
Solution Approach 1:
A reinforcement member is introduced as an intermediary element between the flexible printed circuit board and the camera decoration. This reinforcement member absorbs or distributes the impact force that would otherwise be transmitted to the flexible printed circuit board, preventing damage while allowing the battery to extend in the camera direction.
Solution Approach 2:
The reinforcement member is positioned in advance at the location where the flexible printed circuit board may overlap with the camera decoration. This pre-positioned reinforcement provides protective cushioning against potential external impacts before they occur, ensuring the flexible printed circuit board remains undamaged during battery extension.
2Volume of moving object
If the area of the printed circuit board between the camera and battery is removed to extend the battery, then the battery can be extended, but the connector must be relocated to another area
Solution Approach 1:
The flexible printed circuit board is configured to extend in a direction perpendicular to the main printed circuit board surface, utilizing the vertical dimension rather than horizontal space. This allows the battery to extend in the camera direction without requiring removal of the connector area from the main printed circuit board plane.
Solution Approach 2:
The circuit board system is segmented into multiple components: a rigid printed circuit board for stable connector placement, and a flexible printed circuit board for battery connection that can extend perpendicular to the rigid board. This segmentation allows the connector to remain on the rigid board while the flexible board extends to connect the battery, avoiding connector repositioning complexity.
