Camera Module Lens Carrier Asymmetric Ball Support

The patent applies asymmetry by positioning ball members at asymmetric locations relative to the lens module's center of gravity. Specifically, ball members are arranged such that their support points form an asymmetric pattern, which compensates for the lens module's weight distribution and prevents tilting during focus adjustment movement. This asymmetric arrangement ensures that the lens module moves parallel to the optical axis while maintaining the focus adjustment function.

The patent applies universality by designing the ball member support structure to serve multiple functions simultaneously. The ball members not only support the lens module for focus adjustment but also inherently provide tilt compensation through their asymmetric positioning. Additionally, the guide grooves integrated into the carrier structure serve both to guide the ball members and to maintain the parallel movement of the lens module, reducing the need for separate complex guiding mechanisms.

The patent applies local quality by customizing different portions of the lens module structure for specific functions. The lens module has a substantially quadrilateral overall shape for compactness, but incorporates specific local features such as avoidance portions at corners where ball members are positioned. These localized modifications ensure precise alignment and clearance between the quadrilateral lens module and the ball members, maintaining both compact design and alignment precision.
