Camera Lens Module Spring Suspension Aperture Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera lens modules have a limited aperture size due to the space occupied by the connecting screw structure between the lens barrel and the camera lens mount, restricting the enlargement of the aperture.
Innovation Solution
The camera lens module design eliminates the camera lens mount and connecting screw structure by suspending the lens assembly directly on upper and lower springs, incorporating a coil and magnetic element for movement, and using a spacer block to adjust the lens position, allowing for a larger aperture and reduced total track length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a camera lens mount and connecting screw structure are used to connect the lens barrel, then the structural stability and assembly reliability are improved, but the aperture size is limited due to the space occupied by the connecting structure
Solution Approach 1:
The patent removes the camera lens mount and connecting screw structure from the optical system. The lens barrel is directly suspended on upper and lower springs, eliminating the intermediate mounting structure that previously occupied space and limited aperture enlargement.
Solution Approach 2:
The patent integrates the lens barrel directly with the spring suspension system, merging the previously separate components (lens mount, connecting screws, and springs) into a unified structure where the springs directly support the lens barrel, simplifying the overall assembly.
2Length of stationary object
If the camera lens mount and connecting screw structure are used, then the assembly reliability is improved, but the total track length is increased and the module becomes less compact
Solution Approach 1:
The patent extracts and removes the camera lens mount and connecting screw structure, directly suspending the lens assembly on springs. This elimination of intermediate components reduces the total track length and simplifies the assembly process.
Solution Approach 2:
Instead of using a rigid mount with screws to connect the lens barrel (traditional approach), the patent inverts the approach by using a flexible spring suspension system that directly holds the lens barrel, achieving both compactness and assembly simplicity.
3Area of moving object
If the lens assembly is directly suspended on springs without a camera lens mount, then the aperture can be enlarged and the structure simplified, but the positioning precision and stability may be affected
Solution Approach 1:
The patent introduces a spacer block as an intermediary component between the magnetic element and the bottom of the case. This spacer block presses the lower spring against the bottom, providing a stable reference point and ensuring precise positioning of the lens assembly while maintaining the benefits of the simplified spring suspension structure.
4Ease of manufacture
If the connecting screw structure is removed, then the assembly process is simplified and costs are reduced, but the structural stability may be compromised
Solution Approach 1:
The patent merges the lens barrel directly with the spring suspension system, eliminating the need for separate mounting brackets and connecting screws. The upper spring connects directly to the lens barrel, creating a unified structure that is both easier to assemble and sufficiently stable.
Solution Approach 2:
The patent replaces the mechanical screw connection system with a spring-based suspension system. This substitution eliminates the need for threading, tightening, and alignment operations associated with screws, while providing inherent stability through the elastic properties of the springs.

Function Achieved in This Case
This design enlarges the aperture, simplifies assembly, reduces costs, and enables auto-focusing, while being suitable for single or dual camera lenses, making the module more compact and efficient.
Implementation Method 1
An upper end of the lens barrel main body is suspended on the upper spring and a lower end of the lens barrel main body is suspended on the lower spring
Implementation Method 2
a magnetic element that interacts with the coil for driving the lens assembly to move when the coil is energized

AI summary
A camera lens module includes a case and a bottom coupled with the case to form an accommodating space, having an upper spring, a lens assembly and a lower spring accommodated in the accommodating space. The lens assembly includes a lens barrel main body and a group of lenses provided in the lens barrel main body. An upper end of the lens barrel main body is suspended on the upper spring, and a lower end of the lens barrel main body is suspended on the lower spring. The upper spring is connected with the case, and the lower spring is connected with the bottom. In the camera lens module, the lens assembly is directly suspended on upper and lower springs. This eliminates the camera lens mount of existing camera lens module as well as the connecting screw structure between the camera lens mount and the lens barrel.
