Automated Container Security System with Weight Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The administrative burden of securely dispensing and tracking pressurized containers of controlled substances like OC materials, such as pepper spray, is significant, particularly during shift changes for workers like police and jailers, as existing methods lack automation and reliability in monitoring usage and material levels.
Innovation Solution
A security system that uses machine-readable IDs, such as touch memory buttons, combined with weighing scales to track container contents and user interactions, automating the dispensing and return process, ensuring only authorized users access and return containers with sufficient material, and distinguishing between effective and ineffective containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking methods are used for container dispensing and return, then administrative burden is high and tracking reliability is low, but automation程度 is low
Solution Approach 1:
The patent replaces manual mechanical tracking with an automated electronic system that uses machine-readable IDs (RFID tags, barcodes) and electronic databases to automatically record container dispensing, usage, and return transactions. This substitution of mechanical/manual processes with electronic automation directly improves tracking reliability while increasing automation程度.
Solution Approach 2:
The system enables self-service functionality where containers automatically identify themselves through machine-readable IDs when placed on scales or inserted into readers. The system automatically records weight changes, user information, and transaction details without requiring manual data entry, thereby improving reliability through automated self-reporting.
2Productivity
If automated tracking system is implemented, then administrative burden is reduced and tracking reliability is improved, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single platform: container identification via machine-readable IDs, weight measurement through scales, user authentication, transaction recording, and database management. This multi-functionality consolidates what would otherwise require separate systems, improving administrative efficiency while managing overall system complexity through integration.
Solution Approach 2:
The patent introduces an intermediary electronic database and control system that mediates between various components (scales, readers, user interfaces). This intermediary layer standardizes data exchange and simplifies the interaction between different subsystems, making the overall system more manageable despite its complexity.
3Measurement precision
If weight monitoring is added to track material levels, then material loss detection is improved, but device complexity increases
Solution Approach 1:
The patent combines weight monitoring functionality with the existing container tracking system by integrating scales into the dispensing and return process. The weight measurement is merged with the electronic record-keeping, so that weight data is automatically captured and stored alongside container ID and user information, improving material loss detection without requiring a completely separate system.
Solution Approach 2:
The system performs preliminary weight measurement when containers are initially dispensed, establishing a baseline weight. This preliminary action enables later comparison with return weights to detect material loss, providing continuous monitoring capability through a single integrated measurement process.
Data Source
AI summary
A storage system for material containers provides a readable ID distinguishing each container, and includes a scale that weighs containers, so that the system can distinguish between containers that are sufficiently loaded to be effective and containers that are insufficiently loaded. The system preferably includes storage for containers held in contact with readers of the container IDs. This allows a controller to keep track of containers checked out for use and returned for storage, and to identify containers that have been discharged.
