Imaging Module Lens Barrel Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera modules in mobile devices are bulky and complex, affecting the size and thickness of the device due to the use of a carrier and lens barrel, which complicates the structure and increases volume, hindering the arrangement and stabilization of lenses for improved optical performance.
Innovation Solution
The proposed imaging module integrates lenses directly onto a moving element with a cylindrical configuration, eliminating the need for a lens barrel and incorporating a light-converting element for optical stabilization, while a drive mechanism allows lenses to move along the optical axis for focusing and imaging, and a decoration member is used to reduce the overall thickness and enhance aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carrier and lens barrel are used to arrange lenses, then the lenses can be stabilized and arranged for improved optical performance, but the camera module becomes bulky and complex with increased volume
Solution Approach 1:
The patent merges the lens barrel and carrier into a single integrated moving element. Multiple lenses are directly mounted on this moving element, eliminating the need for separate lens barrels and carriers. This integration maintains the structural support and stabilization functions while significantly reducing the overall volume and complexity of the camera module.
Solution Approach 2:
The patent extracts and eliminates redundant components such as the separate lens barrel and carrier structures. By removing these unnecessary elements and retaining only the essential moving element that performs both support and stabilization functions, the camera module achieves a more compact design without compromising optical performance.
2Reliability
If a periscope lens configuration is used to improve photographic effect, then triple optical focal length is achieved, but the device thickness increases
Solution Approach 1:
The patent employs a periscope optical path design where light travels in a folded path within the camera module. The light-converting element redirects incident light at approximately 90 degrees, allowing the optical axis to be perpendicular to the light inlet. This dimensional change enables the achievement of triple optical focal length while maintaining a thin device profile by utilizing the depth dimension rather than increasing overall thickness.
3Device complexity
If lenses are directly integrated onto a moving element, then the structure is simplified and volume is reduced, but the arrangement and stabilization of lenses becomes more challenging
Solution Approach 1:
The patent combines the lens mounting function and stabilization function into a single moving element structure. This integration simplifies the overall structure by eliminating separate components while the moving element itself is designed with precise geometric features that ensure accurate lens positioning and stabilization, thereby maintaining manufacturing precision despite the reduced component count.
