Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection by inspectors is used to determine placement positions of electronic shelf labels, then position determination can be achieved, but labor costs and time costs increase significantly
Solution Approach 1:
The electronic shelf label automatically reads positioning mark information through its photoelectric geminate transistor and determines its own target position on the power supply guide rail, eliminating the need for manual inspection by inspectors. This self-positioning capability resolves the contradiction by achieving accurate position determination without human intervention, thereby reducing both labor costs and time costs.
2Extent of automation
If image identification system is used to confirm display information and determine placement positions, then automatic determination can be achieved, but implementation costs increase due to high system requirements
Solution Approach 1:
The patent replaces the complex image identification system with a simpler optical-mechanical positioning approach. The photoelectric geminate transistor reads positioning marks on the power supply guide rail to determine position, substituting the need for sophisticated image processing hardware and software with a more straightforward optical sensing mechanism, thereby achieving automation while reducing implementation costs and system complexity.
3Measurement precision
If high-performance image identification system is deployed for commodity display inspection, then inspection accuracy can be improved, but equipment investment costs increase
Solution Approach 1:
The patent employs inexpensive photoelectric geminate transistors and simple positioning marks on the power supply guide rail instead of expensive image identification equipment. This low-cost positioning component integrated into the electronic shelf label achieves accurate position determination without requiring significant equipment investment, resolving the contradiction between inspection accuracy and equipment cost.
