Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance camera systems struggle to identify items purchased in real-time and require post-processing to analyze recorded images, making it difficult to quickly determine purchased items and their corresponding purchase times.
Innovation Solution
A sales data display device and method that simultaneously displays images and sales data, emphasizing keyword items through specific display formats, allowing for quick item identification and abnormality determination by mapping sales data to images and providing statistical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If surveillance cameras are used to record checkout counter images, then image recording capability is improved, but real-time item identification capability deteriorates
Solution Approach 1:
The system divides the checkout process into distinct segments: image capture by surveillance camera, sales data generation by POS terminal, and synchronized display of both. This segmentation allows each component to function independently while maintaining real-time correlation between images and sales data without requiring post-processing of recorded images.
Solution Approach 2:
The display device acts as an intermediary that receives and synchronizes both image data from surveillance cameras and sales data from POS terminals. This intermediary component enables real-time item identification by mapping sales data to corresponding images without requiring analysis of recorded images, thus resolving the time delay issue.
2Loss of information
If all sales data items are displayed with equal emphasis, then complete information is provided, but quick identification of important items deteriorates
Solution Approach 1:
The display device applies different visual qualities to different data elements: keyword items are displayed with emphasis (highlighting, larger font, or special markers) while non-keyword items are displayed with standard formatting. This local differentiation allows users to quickly identify important items while still accessing complete sales information, resolving the contradiction between information completeness and quick identification.
