Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for supporting camera modules in electronic devices face issues such as increased repulsive forces from flexible printed circuit boards, leading to eccentricity and tilting of camera modules, which degrade optical performance and appearance.
Innovation Solution
A supporting structure with an extension extending toward the camera module's sensing area, utilizing an elastic cantilever-shaped design to prevent and reduce tilting, aligned with the optical hole and camera window without separate fixing members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a supporting member is provided to support the inclined camera structure, then the camera module alignment is improved, but the repulsive force from flexible printed circuit boards increases causing excessive eccentricity and lifting
Solution Approach 1:
The supporting member is divided into a first supporting portion that contacts the camera module and a second supporting portion that contacts the housing, with a connecting portion between them. This segmentation allows the supporting member to distribute forces effectively and maintain camera alignment without excessive repulsive forces on the flexible printed circuit board.
Solution Approach 2:
The supporting member extends in multiple directions with the first supporting portion extending in a first direction, the second supporting portion extending in a second direction, and the connecting portion extending in a third direction. This multi-dimensional configuration provides stable support for the inclined camera structure while minimizing interference with other components.
2Stability of the object's composition
If a separate fixing tape is provided to fix the camera module, then the alignment stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The supporting member integrates multiple functions into a single structure: it provides mechanical support for the inclined camera, maintains alignment stability, and eliminates the need for separate fixing tapes. The first supporting portion, second supporting portion, and connecting portion work together as one unified component.
Solution Approach 2:
The supporting member serves multiple purposes: supporting the camera module, maintaining its inclined alignment, preventing excessive eccentricity, and reducing lifting. This multi-functional design replaces what would otherwise require multiple separate components including fixing tapes.
