Universal Focus-Adjustment Apparatus with Movable Latch Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera modules with different focal lengths require distinct focus-adjustment apparatuses, increasing manufacturing costs and complexity due to varying lens module sizes.
Innovation Solution
A focus-adjustment apparatus featuring a rotation mechanism with latch rods and a drive mechanism that can adjust lens modules of different sizes by rotating the adjustment structure relative to the optoelectronic chip, using a common set of interchangeable latch rods to accommodate various lens module diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different focus-adjustment apparatuses are provided for lens modules of different sizes, then focus adjustment accuracy is improved, but manufacturing cost and process complexity increase
Solution Approach 1:
The patent designs a focus-adjustment apparatus where a single container can accommodate lens modules of different sizes through adjustable latch rods. The latch rods can be positioned at different locations to match various lens module diameters, allowing one apparatus to perform multiple functions for different camera module specifications, thereby reducing manufacturing complexity while maintaining focus adjustment accuracy
Solution Approach 2:
The latch rods are designed to be movable and adjustable within the container rather than fixed. This dynamic structure allows the latch rods to adapt their positions according to the size of the lens module being adjusted, enabling the same apparatus to handle multiple lens module sizes effectively without requiring separate fixed apparatuses for each size
2Manufacturing precision
If different focus-adjustment apparatuses are provided for lens modules of different sizes, then focus adjustment accuracy is improved, but manufacturing cost increases
Solution Approach 1:
By designing a universal focus-adjustment apparatus that can handle multiple lens module sizes through adjustable latch rods, the patent eliminates the need to manufacture separate apparatuses for each lens module size. This single apparatus serves multiple purposes, significantly reducing manufacturing costs while maintaining the ability to achieve accurate focus adjustment for different camera module specifications
3Device complexity
If a fixed-size container is used for focus adjustment, then structural simplicity is maintained, but adaptability to different lens module sizes is reduced
Solution Approach 1:
The container maintains a simple fixed structure overall, but incorporates dynamic latch rods that can be adjusted within the container. This combination allows the simple container structure to accommodate lens modules of different sizes by adjusting the latch rod positions, achieving both structural simplicity and adaptability without requiring a complex adjustable container

AI summary
A focus-adjustment apparatus which can be applied during manufacture of camera modules includes a rotation mechanism, a drive mechanism, an elevating mechanism, an optoelectronic chip, and a lens module. The rotation mechanism includes a container and movable latch rods therein. The drive mechanism can rotate the rotation mechanism, and the elevating mechanism with optoelectronic chip attached is under the rotation mechanism. The lens module includes a support element adjacent to the optoelectronic chip, an adjustment structure rotatably disposed on the support element, and a lens above the optoelectronic chip in the adjustment structure. When the elevating mechanism raises the lens module and the drive mechanism rotates the rotation mechanism, at least one of the latch rods rotates the adjustment structure, so as to change the distance between the lens and the optoelectronic chip and achieve correct focus.
