Multi-Direction Lens Reflection Testing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reflection testing methods for lens modules are inefficient as they can only test reflections in one direction at a time, requiring individual testing for each direction and thus taking a long time.
Innovation Solution
A reflection-testing device and method utilizing multiple light sources placed around the lens module and an image capturer at the other end to simultaneously test for unwanted reflections from various directions, allowing for simultaneous illumination and image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single light source is used to test reflections in one direction at a time, then the testing procedure is simple, but the testing time is long and efficiency is low
Solution Approach 1:
The invention divides the single light source into multiple light sources (first light source, second light source, etc.) positioned at different locations around the lens module. Each light source tests reflections from a specific direction, allowing simultaneous multi-directional testing instead of sequential single-direction testing, thereby improving productivity while maintaining manageable device complexity through modular segmentation.
Solution Approach 2:
The invention transitions from one-dimensional sequential testing (one direction at a time) to three-dimensional simultaneous testing by positioning multiple light sources at different spatial locations around the lens module. This dimensional expansion allows reflections from multiple angles to be tested concurrently, dramatically improving testing efficiency without proportionally increasing device complexity.
2Loss of time
If multiple light sources are used to test reflections from multiple directions simultaneously, then the testing time is reduced and efficiency is improved, but the device complexity increases
Solution Approach 1:
The testing device is segmented into multiple independent light source units positioned at different locations, each capable of simultaneous operation. This segmentation allows the system to test multiple reflection directions at the same time rather than sequentially, reducing total testing time while keeping each individual light source unit simple and manageable, thus controlling overall device complexity.
Solution Approach 2:
The invention merges multiple light source functions into a single integrated testing device structure. By combining first light source, second light source, and other light sources into one unified device that tests multiple directions simultaneously, the system reduces testing time significantly while avoiding the complexity of multiple separate testing devices through functional integration.
