Camera Module Reflector Layout for Flare Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules suffer from flare issues due to optical path interference, which affect image quality and are not effectively addressed by current designs.
Innovation Solution
Incorporation of a reflector between lenses to redirect light and a blocking wall to manage optical paths, along with a concealing portion to hide internal components, reducing thickness and maintaining optical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reflector is added to redirect light in the optical path, then optical zoom function is improved, but device complexity increases
Solution Approach 1:
The reflector is nested within the existing lens holder structure, utilizing the space between the first and second lenses. This allows the optical zoom function to be enhanced without adding external complexity to the camera module assembly.
Solution Approach 2:
The reflector acts as an intermediary component that redirects light between the first lens and second lens, enabling optical path manipulation without requiring complete redesign of the lens system.
2Object-affected harmful factors
If a blocking wall is added to block optical path, then flare suppression is improved, but device complexity increases
Solution Approach 1:
The blocking wall is strategically positioned only in the specific region where flare occurs (between the reflector and lens holder), providing localized flare suppression without adding blocking structures throughout the entire optical path.
Solution Approach 2:
The blocking wall is designed as a separate, segmented component that can be independently positioned and adjusted within the lens holder, allowing precise control over where optical paths are blocked without complicating the overall structure.
3Shape
If internal components are concealed, then aesthetic appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The concealing portion is merged with the existing lens holder structure, combining the support function and the aesthetic concealing function into a single integrated component, which simplifies manufacturing compared to adding a separate concealing cover.
4Length of moving object
If lens holder overlaps peripheral portion, then thickness is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The lens holder is designed to overlap the peripheral portion in the radial dimension rather than extending in the axial dimension, achieving thickness reduction by utilizing space in a different dimensional orientation.
