Sales Management Device Customer Identification Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sales management systems face challenges in accurately identifying customers when multiple individuals are present near a commodity shelf, leading to increased information processing load and complexity in determining who purchases a commodity.
Innovation Solution
A sales management device with programmed processing circuitry that receives data from sensors to identify customers and manage sales data registration, provisionally registering data when multiple customers are identified, and finalizing registration only when one customer is confirmed, while preventing accounting for customers with provisionally registered data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system uses complicated information processing to specify the customer who picks up the commodity when multiple customers are present, then the customer identification accuracy is improved, but the information processing load increases
Solution Approach 1:
The system performs preliminary registration of sales data for all customers identified near the display place before final determination. This preliminary action allows the system to prepare data structures in advance and avoid complex real-time processing when the actual purchase occurs, thereby reducing the information processing load while maintaining identification accuracy
Solution Approach 2:
The system introduces an intermediary mechanism using display place sensors and customer identification devices to mediate between the commodity movement detection and the final purchase determination. This intermediary layer filters and pre-processes customer information, reducing the complexity of direct analysis and lowering the overall information processing load
2Reliability
If the system provisionally registers sales data for multiple customers when customers are identified near the display place, then the reliability of sales data registration is improved, but the device complexity increases
Solution Approach 1:
The registration process is segmented into distinct phases: preliminary registration phase (when customers are identified near the display place) and final registration phase (when purchase is confirmed). This segmentation allows the system to handle complexity in manageable stages, improving reliability by ensuring data is registered appropriately at each phase without overwhelming the system
Solution Approach 2:
The system dynamically adjusts the registration state based on real-time conditions. When multiple customers are identified, the system transitions to provisional registration mode. When purchase confirmation occurs, it transitions to final registration mode. This dynamic adaptation simplifies the overall process by using conditional logic rather than complex parallel processing

AI summary
A sales management device includes processing circuitry having programmed instructions to receive first data from a first sensor indicating movement of a commodity displayed in a display place. The sales management device receives second data from a second sensor identifying at least one customer located near the display place when the commodity is moved. The sales management device provisionally registers, in response to a determination that a plurality of customers are identified in the second data, sales data of the commodity in purchase lists of the respective customers. The sales management device prevents accounting for the first customer in response to a determination that a purchase list of the first customer includes provisionally registered sales data.
