NFC Container Arrangement with Breakable Loop for Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container arrangements with RFID labels for pharmaceutical products face challenges in ensuring secure data access and tamper evidence, particularly when multiple units or doses are involved, as current solutions either disable data access after opening or allow unauthorized readability during shipment.
Innovation Solution
A container arrangement with a Near Field Communication (NFC) system that includes a breakable conductive loop and sensing-switching arrangements, which irreversibly deregulates its primary operation mode upon initial opening and allows re-enablement upon unloading, ensuring secure data access and tamper evidence by shifting the NFC antenna's resonance frequency or enabling alternative operation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data accessibility is disabled after opening the container, then tamper evidence and security are improved, but data readability for legitimate purposes (such as tracking multiple doses) is worsened
Solution Approach 1:
The NFC system dynamically changes its operational state based on container status. The system transitions between different modes (accessible, inaccessible, alternative operation) depending on whether the container is sealed, opened, or unloaded, allowing flexible data access control that adapts to the current situation rather than being statically disabled after opening
Solution Approach 2:
The system changes the resonance frequency parameter of the NFC antenna to shift between primary and alternative operation modes. By modifying this physical parameter, the system can enable or disable data accessibility and switch between different communication protocols without hardware modification, resolving the contradiction between security and data readability
2Reliability
If the NFC antenna resonance frequency is shifted to disable primary operation mode, then data security is improved, but communication functionality is worsened
Solution Approach 1:
An alternative NFC operation mode acts as an intermediary when the primary mode is disabled. This alternative mode provides a fallback communication channel that maintains basic functionality while the primary secure mode is inactive, ensuring that communication capability is preserved even when data security requires the primary mode to be disabled
Solution Approach 2:
The system periodically switches between primary and alternative operation modes based on container events. The primary mode is enabled during sealed transport for maximum security, while the alternative mode activates after opening or during unloading to maintain communication functionality, creating a periodic pattern of mode switching that balances security and operability

AI summary
A container arrangement (100) is disclosed, which is preferably destined for pharmaceutical products. The container arrangement includes a container body (110) and a first wireless communication systems (210) composed of a NFC system (210) including an NFC antenna (141). The container arrangement further includes a first and/or a second sensing-switching arrangement (143; 280) configured to include a preset status inhibiting a standardized operability of the first wireless communication system (210). The first sensing-switching arrangement (143) is configured to deregulate its preset status upon an initial opening event and the second sensing-switching arrangement (280) is configured to deregulate its preset status upon an unloading event.
