Sensor-Based Inventory Controller for Storage Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate stock management of products is challenging when they are placed in incorrect storage locations, leading to incorrect detection of product amounts and potential over-ordering.
Innovation Solution
An information processing device equipped with a sensor that detects the amount of products in storage locations and a controller that transmits notifications to user terminals when the decrease in product amount exceeds a threshold value, indicating potential storage errors, such as incorrect placement or IC tag issues.

Engineering Contradiction Analysis
1Extent of automation
If product stock is managed based on sensor detection values from storage locations, then automated stock monitoring is achieved, but storage errors lead to inaccurate stock management
Solution Approach 1:
The system implements feedback by notifying users when abnormal decreases in product amount are detected. The notification mechanism provides real-time information about potential storage errors, allowing users to correct misplaced products. This feedback loop resolves the contradiction by maintaining automated monitoring while improving accuracy through user intervention triggered by abnormal detection patterns.
2Measurement precision
If the system monitors product decrease amounts to detect storage errors, then stock accuracy improves, but false notifications may occur due to legitimate product consumption
Solution Approach 1:
The system uses parameter changes by comparing the decrease amount against a predetermined threshold value. This threshold parameter filters out normal consumption patterns that fall below the threshold, preventing false notifications. Only decreases exceeding the threshold trigger notifications, thus resolving the contradiction between detecting storage errors and avoiding false alarms from legitimate product usage.

AI summary
An information processing device includes a controller configured to execute acquiring a detection value obtained by detecting an amount of a product stored in a storage location corresponding to the product by a sensor, and transmitting a notification regarding a storage error of the product to a user terminal in a case where a decrease amount of the product based on the detection value of the sensor in a predetermined period is larger than a threshold value.
