Fluorescent Lubricant for Camera Module Friction and Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera module lubricants fail to effectively reduce friction between moving components and are difficult to detect, leading to potential movement failures and maintenance challenges.
Innovation Solution
A fluorinated lubricant containing a fluorescent material that emits light when illuminated with UV light is applied to frictional areas within the camera module, allowing for non-invasive detection and reducing friction between moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lubricants are used in camera modules, then friction between moving components is reduced, but the lubricants are difficult to detect and their presence cannot be confirmed
Solution Approach 1:
The patent applies fluorescent materials to the lubricant composition, enabling the lubricant to emit fluorescent light when illuminated with UV light. This allows for easy visual detection of lubricant presence and distribution in the camera module without affecting its friction-reducing properties
Solution Approach 2:
The patent introduces fluorescent compounds as an intermediary substance mixed with the lubricant. This intermediary enables detection functionality while the lubricant itself continues to perform its primary function of reducing friction between moving components
2Reliability
If lubricants are applied to moving components, then friction is reduced, but it becomes difficult to monitor lubricant distribution and effectiveness
Solution Approach 1:
The fluorescent properties of the lubricant enable visual monitoring of lubricant distribution across moving components. When UV light illuminates the camera module, the fluorescent lubricant glows, providing real-time information about where lubricant is present and how it is distributed
Solution Approach 2:
The fluorescent detection capability provides feedback information about lubricant presence and distribution. This allows operators to verify proper lubricant application and monitor lubricant effectiveness without disassembling the camera module
