Behavior Analysis Device Using Stockout Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing behavior analysis systems do not accurately reflect stockout situations of goods, which affects the accuracy of customer behavior analysis, as they do not consider the absence of goods on shelves.
Innovation Solution
A behavior analysis device and system that includes sensors to detect approach information and determine stockout positions among displayed goods, allowing for behavior analysis based on both approach and stockout information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If behavior analysis is performed using only approach information without stockout information, then the analysis system is simple to operate, but the analysis accuracy deteriorates due to false impressions from out-of-stock items
Solution Approach 1:
The patent merges approach information and stockout information into a unified behavior analysis system. The determination unit combines data from the approach information acquisition unit and the stockout determination unit to perform comprehensive behavior analysis, eliminating false impressions caused by out-of-stock items while maintaining systematic operation
Solution Approach 2:
The determination unit acts as an intermediary that processes both approach information and stockout information before feeding them to the behavior analysis unit. This intermediary component integrates multiple data sources and filters out misleading information from out-of-stock scenarios, improving analysis accuracy without requiring direct complex interactions between all system components
2Measurement precision
If stockout determination is added to the behavior analysis system, then the analysis accuracy improves by reflecting actual stockout situations, but the device complexity increases
Solution Approach 1:
The patent segments the behavior analysis system into distinct functional units: an approach information acquisition unit, a stockout determination unit, and a behavior analysis unit. Each unit performs a specific function independently, allowing the system to handle complex stockout analysis without overwhelming overall system complexity. The segmentation enables modular design and easier maintenance
Solution Approach 2:
The determination unit serves multiple functions by simultaneously processing approach information and stockout information, and by generating both stockout determination results and behavior analysis inputs. This multi-functionality reduces the need for separate dedicated components, thereby improving analysis accuracy while limiting the increase in device complexity

AI summary
A behavior analysis device includes an approach information acquisition unit configured to acquire approach information indicating whether or not a person has approached a shelf on which a plurality of goods are displayed, a determination unit configured to determine as stockout information a position of a stockout item which is out of stock among the plurality of goods displayed on the shelf and a stockout of the stockout item, and an analysis unit configured to perform behavior analysis of the person on the basis of the approach information and the stockout information.
