Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection methods for light-emitting modules in electronic devices rely on manual processes, which are subjective and time-consuming due to variations in operator experience and visual acuity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual detection methods are used by operators, then the detection process can be performed with simple equipment, but the detection efficiency is low and results are subjective due to operator differences
Solution Approach 1:
The patent replaces the manual mechanical detection system with an automated image processing system. The image-capturing module captures images of light-emitting modules, and the processing module automatically analyzes these images to detect defects, replacing operator visual inspection and manual judgment with automated computational analysis.
Solution Approach 2:
The patent creates a digital copy (image) of the light-emitting module for detection purposes. Instead of directly examining the physical module, the system captures an image representation and performs detection on this copy, enabling automated analysis while preserving the original module.
2Measurement precision
If manual detection methods are used, then the equipment required is simple, but the detection precision varies due to operator experience and visual acuity differences
Solution Approach 1:
The patent replaces the human operator's visual system with an automated image processing system. The processing module uses algorithmic analysis to objectively evaluate light-emitting modules, eliminating variability caused by different operators' experience and visual acuity while maintaining consistent detection precision.
Solution Approach 2:
The system provides objective feedback through automated image analysis. The processing module compares captured images against detection criteria and provides consistent, repeatable results without the subjective interpretation that affects manual detection, ensuring uniform precision across all detections.
3Productivity
If manual detection processes are used, then the detection system remains simple, but the detection process consumes significant time for each module
Solution Approach 1:
The patent replaces sequential manual inspection with parallel automated image processing. Multiple light-emitting modules can be detected by capturing and processing images simultaneously or in rapid succession, dramatically increasing detection speed while the automated system handles the complexity of analysis.
