Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual visual adjustment of luminance is performed by workers, then image uniformity can be achieved, but work time becomes long and finishing varies depending on worker skill
Solution Approach 1:
The patent replaces the manual visual adjustment mechanism with an automated image processing system. A camera captures images of the LED display, and a processor automatically analyzes luminance values and calculates correction values, eliminating the need for workers to manually adjust each LED module while maintaining uniformity correction capability
Solution Approach 2:
The system enables self-adjustment by having the LED display device automatically calculate and apply luminance correction values based on captured images. The device performs its own uniformity adjustment without external human intervention, using internal processing units to analyze luminance distribution and generate correction data
2Manufacturing precision
If manual visual adjustment of luminance is performed by workers, then image uniformity can be achieved, but finishing varies depending on worker skill
Solution Approach 1:
The patent replaces the manual visual adjustment mechanism with an automated image processing system. A camera captures images of the LED display, and a processor automatically analyzes luminance values and calculates correction values, eliminating the need for workers to manually adjust each LED module while maintaining uniformity correction capability
Solution Approach 2:
The system implements a feedback mechanism where the LED display device captures images of its own display, analyzes the luminance distribution, and uses the analysis results to calculate and apply correction values. This closed-loop feedback ensures consistent and reliable uniformity adjustment regardless of operator skill level
3Productivity
If automated adjustment is implemented, then work time is reduced and consistency is improved, but system complexity increases
Solution Approach 1:
The patent integrates multiple functions into the LED display device itself: it can display images, capture images through an integrated camera, process the captured images to analyze luminance, calculate correction values, and apply the corrections. This multi-functionality reduces the need for separate external devices and simplifies the overall system architecture
Solution Approach 2:
The patent combines the adjustment control unit, image capture function, and image processing capability into a single integrated LED display device. By merging these previously separate components into one unified system, the patent reduces system complexity while maintaining automated adjustment functionality
