Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods (integrating spheres or photo diodes) are used for inspecting luminary arrays, then measurement precision can be achieved, but measurement time increases and operation complexity increases due to the need for precise alignment and careful positioning with each luminary
Solution Approach 1:
The patent replaces traditional mechanical measurement systems (integrating spheres and photo diodes requiring manual positioning) with an optical imaging system using a camera. The camera captures images of the luminary array, and image processing algorithms automatically determine luminary positions and alignments, eliminating the need for manual alignment operations while maintaining measurement precision.
Solution Approach 2:
The patent creates an optical copy (image) of the luminary array using a camera instead of directly measuring each luminary with physical instruments. This image copy contains all the position and alignment information needed for inspection, allowing simultaneous measurement of multiple luminaries without repeated physical contact or alignment operations.
2Measurement precision
If traditional methods (integrating spheres or photo diodes) are used for inspecting luminary arrays, then measurement precision can be achieved, but device complexity and ease of operation worsen due to the need for careful positioning with each luminary
Solution Approach 1:
The patent replaces complex mechanical positioning operations with automated optical imaging. The camera system automatically captures the luminary array configuration, and computational algorithms handle the position and alignment determination, eliminating the need for operators to manually position and align measurement instruments with each luminary.
Solution Approach 2:
The system performs self-service by automatically determining luminary positions and alignments through image processing algorithms without requiring manual intervention for positioning or alignment. The image data itself contains the information needed for measurement, allowing the system to independently complete the inspection task.
3Measurement precision
If traditional methods are used for inspecting luminary arrays, then measurement can be performed, but productivity decreases due to time-consuming alignment procedures
Solution Approach 1:
The patent merges the measurement of multiple luminaries into a single simultaneous operation. Instead of measuring each luminary separately with traditional instruments, the camera captures the entire luminary array in one image, and the processing system extracts position and alignment information for all luminaries simultaneously, dramatically increasing inspection throughput.
Solution Approach 2:
The patent enables continuous measurement operation where the camera continuously captures images of the luminary array without interruption. The image processing can be performed continuously or in rapid succession, eliminating the sequential nature of traditional measurements and maintaining continuous productive action throughout the inspection process.
