Paper Sheet Theft Prevention via Identification Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies cannot fully prevent the theft of paper sheets during transport, as they primarily focus on securing paper sheets within a deposit device.
Innovation Solution
A paper sheet processing system that includes a processing device to count paper sheets and a management device that acquires and transmits paper sheet identification information. This information is used to specify lost paper sheets and notify external devices, preventing their reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper sheet identification information is acquired and transmitted to the management device, then the ability to detect and prevent theft is improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The system divides the theft prevention function into separate modules: an acquiring unit in the paper sheet processing device that captures identification information, a transmission unit that sends data to the management device, and a specifying unit in the management device that analyzes lost sheets. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining high reliability.
Solution Approach 2:
The management device acts as an intermediary between the paper sheet processing device and external devices. It receives identification information from the processing device, specifies which sheets are lost, and notifies external devices without requiring direct complex interactions between all components. This intermediary approach simplifies the architecture while improving theft prevention capability.
2Reliability
If paper sheet identification information is notified to external devices, then the prevention of stolen paper sheet reception is improved, but the information processing time and communication overhead increase
Solution Approach 1:
The system performs preliminary actions by acquiring and storing paper sheet identification information at the time of normal processing, rather than detecting theft at the moment it occurs. The management device maintains a database of identification information and can immediately specify lost sheets when theft is detected, reducing the time needed for investigation and notification.
Solution Approach 2:
The system establishes a feedback loop where the management device notifies external devices of lost paper sheet identification information, which then feedback to prevent reception of stolen sheets. This feedback mechanism ensures that the system learns from theft events and adjusts its behavior to prevent future thefts, improving reliability while managing processing time efficiently.
