Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional light sources are used for illuminating tab portions, then the detection system is simple, but the detection effect of multilayer tabs is poor
Solution Approach 1:
The light source is divided into multiple independent light sources arranged in an array, with each light source illuminating a specific region. This segmentation allows each light source to be optimized for specific illumination requirements, improving overall detection effect while maintaining manageable system complexity through modular design
Solution Approach 2:
The light sources are arranged in a curved array configuration rather than a straight line, creating a three-dimensional illumination pattern that better matches the curved surface of multilayer tabs. This dimensional change ensures uniform light distribution across the tab surface, significantly improving detection quality
2Illumination intensity
If a single light source is used, then the device is simple, but uniform illumination of multilayer tabs cannot be achieved
Solution Approach 1:
Multiple light sources are distributed along a curved array, with each light source responsible for illuminating a specific segment of the tab portion. This segmentation of illumination responsibility ensures that light is distributed uniformly across the entire multilayer tab surface, avoiding both over-illumination and under-illumination zones
Solution Approach 2:
Multiple individual light sources are combined into a coordinated array system that functions as a unified illumination solution. The curved arrangement of these merged light sources creates a collective illumination pattern that achieves uniform coverage across the multilayer tabs, which cannot be accomplished by a single light source
