Innovation Solution
A smart safe system with electronically locked coin vaults equipped with scales and monitoring circuitry that calculates the number of rolls based on pre-programmed weights, detects anomalies, and restricts access, using user authentication and wireless communication for secure inventory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inventory tracking is used, then device complexity is reduced, but productivity and measurement precision deteriorate due to time-consuming manual counting and potential errors
Solution Approach 1:
The patent replaces manual mechanical counting with electronic scale-based weight measurement systems. Scales continuously monitor the weight of coin rolls on shelves, automatically calculating inventory levels without human intervention. This substitution of mechanical manual tracking with electronic sensing systems resolves the contradiction by dramatically improving productivity while the integrated controller manages complexity.
Solution Approach 2:
The system enables self-service inventory monitoring where the scales and controllers automatically track and report coin inventory levels without requiring manual counting staff. The continuous weight monitoring and automatic calculation features allow the system to serve itself, improving productivity while the standardized measurement processes help manage system complexity.
2Reliability
If no tamper detection system is implemented, then device complexity is reduced, but reliability deteriorates due to undetected theft and manipulation
Solution Approach 1:
The patent implements feedback mechanisms where scales continuously monitor weight changes and the controller receives real-time data to detect potential tampering. When weight changes indicate possible theft or manipulation, the system generates alerts and logs events. This feedback loop improves reliability by enabling active security monitoring while the automated detection processes help manage the complexity of the monitoring system.
Solution Approach 2:
The controller acts as an intermediary between the scales and the security system, processing weight data and determining whether tampering has occurred. This intermediary layer manages complexity by centralizing the analysis logic, allowing the system to provide reliable tamper detection without requiring each scale to independently implement complex security algorithms.
3Measurement precision
If continuous weight monitoring is implemented, then measurement precision and reliability improve, but use of energy increases due to continuous operation of scales and controllers
Solution Approach 1:
The patent employs periodic sampling of weight data rather than truly continuous monitoring. The scales take measurements at regular intervals, and the controller processes these periodic readings to detect inventory changes and tampering events. This periodic approach maintains measurement precision sufficient for security purposes while significantly reducing energy consumption compared to constant monitoring.
Solution Approach 2:
The system implements monitoring at a level of precision and frequency that exceeds minimum requirements for basic inventory tracking, providing enhanced security and detection capabilities. By using weight-based measurement rather than simple presence detection, the system achieves superior measurement precision while the periodic nature of the sampling keeps energy consumption manageable.

Function Achieved in This Case
The system provides comprehensive tamper coverage, accurate inventory tracking, and secure access control, reducing theft and manual counting time while enabling real-time monitoring and alerts for tamper events.
Implementation Method 1
On the top of each shelf, there is a scale designed to monitor the weight of the rolls of coins placed on that shelf.

AI summary
A secure enclosure is described which is designed to offer inventory management and tamper detection for the storage and removal of rolled coins and other valuable items. Within the secure enclosure a plurality of shelves are provided. Each shelf may have its own scale for the purpose of weighing the contents supported by its shelf. Each shelf may be designed for the storage of one particular denomination of rolled coin. Monitoring circuitry interfaces with the scales for the purpose of determining the quantity of rolls upon each shelf, and the possibility for an erroneous deposit or removal of rolls supported by a shelf or an improper access to other contents on the shelf. A further approach detects multiple types of rolls of coins utilizing a single scale.
