Lens Module Soft Plate Folding Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical image stabilization systems require a large horizontal space for the soft plate, limiting the flexibility of the internal lens structure due to the need for sufficient movement space, which restricts design and assembly options.
Innovation Solution
A lens module design featuring a soft plate with a movable portion that folds along the lower end surface of the focusing module, reducing horizontal space occupation and enhancing assembly flexibility by utilizing vertical space, including a through slot in the deflection base and a folding portion connected to the focusing module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the soft plate is made with a large length to provide sufficient movement space for the movable end, then the movement space is sufficient, but the horizontal space occupied by the soft plate increases greatly
Solution Approach 1:
The soft plate transitions from a traditional horizontal linear arrangement to a three-dimensional folded structure. The first folded portion bends downward at an angle between 45-135 degrees, and the second folded portion bends upward, creating vertical dimension utilization. This dimensional transformation allows the soft plate to maintain sufficient length for movement while reducing its horizontal footprint, directly resolving the contradiction between movement space and horizontal space occupation.
2Ease of operation
If the soft plate occupies large horizontal space, then movement space is sufficient, but the flexibility of designing internal structure of the lens module is greatly reduced
Solution Approach 1:
By folding the soft plate in the vertical dimension, the design frees up horizontal space that can then be utilized for more flexible internal structure arrangement. The folded portions create a compact configuration that accommodates various lens module internal structures without compromising the movement space required for optical image stabilization.
3Reliability
If the soft plate is made long to prevent the fixed end from affecting the movable end, then the stabilization function is maintained, but space efficiency is reduced
Solution Approach 1:
The folded structure maintains the necessary soft plate length for reliable optical image stabilization by extending vertically rather than horizontally. The first folded portion bending downward and the second folded portion bending upward creates sufficient length while improving space efficiency, allowing the stabilization function to be maintained without sacrificing compactness.

AI summary
A lens module and a photography device are provided. The lens module includes a focusing module, a deflection base, and a soft plate. The deflection base is provided with a through slot. The focusing module is disposed in the through slot and is connected to an inner wall of the through slot, and the deflection base is configured to drive the focusing module to deflect. The soft plate includes a movable portion and a fixed portion. An end of the movable portion is provided with a folding portion, the folding portion is connected to a side wall at an end of the focusing module, and the folding portion is folded toward a lower end surface of the focusing module, to enable the movable portion to extend along the lower end surface of the focusing module toward the fixed portion and to be connected to the fixed portion.
