Inventory Access Control via User Context and Predicted Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing inventory in facilities lack effective control over physical access to items, leading to issues such as breakage, theft, and misplacement, particularly in environments where different users have varying access permissions.
Innovation Solution
A system utilizing sensors and an inventory management system to generate access configuration data based on user context, which controls physical access through mechanisms like movable barriers and dispensers, ensuring that only authorized users can access specific items by determining their identity, location, and predicted path within the facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical access to items is restricted through controlled mechanisms, then item security and proper placement are improved, but system complexity and operational difficulty increase
Solution Approach 1:
The system enables self-service access control where inventory locations automatically determine and enforce access permissions based on user context data. The inventory locations independently evaluate whether to permit or prevent physical access without requiring manual intervention from security personnel, thereby improving item security while avoiding proportional increases in operational complexity.
Solution Approach 2:
The patent replaces traditional mechanical access control systems with an information-based system that uses sensors, processors, and data evaluation to control physical access. Instead of complex mechanical locks and barriers, the system uses electronic sensors to detect user presence and context, processes this information, and automatically adjusts physical access permissions, reducing mechanical complexity while maintaining security.
2Object-affected harmful factors
If dynamic access control based on user context is implemented, then item protection from breakage and theft is improved, but measurement and detection difficulty increase
Solution Approach 1:
The system employs multi-functional sensors that simultaneously perform multiple detection tasks: identifying user presence, determining user location, tracking user movement paths, and assessing user context all through integrated sensing mechanisms. This universal approach allows the system to protect against theft and breakage by comprehensively monitoring user context without requiring separate complex detection systems for each function.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw sensor data about users and transforms it into meaningful context information. This intermediary system evaluates sensor inputs against predefined criteria and user profiles, converting complex detection data into actionable access decisions, thereby reducing the difficulty of interpreting user context while improving protection against harmful activities.
3Productivity
If sensors and access control mechanisms are deployed throughout the facility, then productivity through automated inventory management is improved, but device complexity and initial investment increase
Solution Approach 1:
The system merges multiple inventory management functions into integrated sensor nodes and inventory locations that simultaneously perform detection, data processing, and access control. By combining these functions into unified components rather than separate systems, the patent achieves automated inventory management that improves productivity while limiting the increase in overall facility infrastructure complexity.
Data Source
AI summary
Access to items stored within an inventory location of a facility may be controlled using physical access control mechanisms. A user within a facility is detected by sensors, such as imaging sensors. Context data for the user is generated based on the sensor data. The context data includes permission data indicative of portions of the inventory location that are accessible or inaccessible to the user. In addition, a predicted path of the user may also be determined based on historical data of the user or other users of the facility. Using the permission data and the predicted path of the user, configuration data may be generated to specify the level of access control to be applied to the different portions of the inventory location. The configuration data is sent to access control mechanisms of the inventory location to prevent or allow access to such portions of the inventory location.
