Camera Module Buffer Layer for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As camera module components, such as optical filters, increase in size with higher resolution, they become more susceptible to damage from impact forces when electronic devices fall, leading to a risk of breakage.
Innovation Solution
Incorporating a buffer layer made of elastic material, such as rubber, within the camera module's supporting seat to absorb impact forces and protect the optical filter during drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the optical filter size is increased to support higher resolution, then the imaging quality is improved, but the susceptibility to impact damage increases
Solution Approach 1:
The patent applies beforehand cushioning by placing a buffer layer between the lens holder and the supporting seat before impact occurs. This buffer layer, made of elastic material, is pre-positioned to absorb impact forces when the device is dropped, protecting the optical filter from damage while allowing the filter to maintain its larger size for high-resolution imaging.
2Measurement precision
If the optical filter size is increased to support higher resolution, then the imaging quality is improved, but the risk of breakage during drops increases
Solution Approach 1:
The patent uses an intermediary approach by introducing a buffer layer as a mediator between the lens holder and the supporting seat. This buffer layer acts as an intermediate element that absorbs and dissipates impact forces, reducing the transmission of harmful shock waves to the optical filter while allowing the filter to maintain its larger dimensions for high-resolution imaging.
3Reliability
If a buffer layer is added to protect the optical filter, then the impact resistance is improved, but the device complexity increases
Solution Approach 1:
The patent applies flexible shells and thin films by using a thin buffer layer made of elastic material between the lens holder and the supporting seat. This thin flexible layer provides effective impact protection without significantly increasing the overall device complexity or volume, as it can be integrated into the existing supporting seat structure.

Function Achieved in This Case
The buffer layer effectively reduces the risk of filter damage by cushioning the impact force, ensuring the optical filter remains intact during accidental drops.
Implementation Method 1
Incorporating a buffer layer made of elastic material, such as rubber, within the camera module's supporting seat to absorb impact forces and protect the optical filter during drops

AI summary
A camera module includes a supporting seat, a filter, and a lens assembly. The supporting seat defines a window passing through the supporting seat. An annular flange extending from an inner wall of the window towards the central axis of the window. The filter is fixed on the annular flange. The lens assembly is fixed on the supporting seat. The lens assembly includes a lens holder and a lens disposed in the lens holder. A surface of the supporting seat facing the lens assembly is recessed to form at least two receiving slots surrounding the window. A buffer layer is disposed in each of the at least two receiving slots. An orthogonal projection of the lens on a plane of the buffer layer at least partially overlaps with the buffer layer, and lens is spaced apart from the filter.
