Safe Unlocking Machine RFID Verification Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe unlocking machines experience wear and reduced durability due to electrical contact verification, and are prone to water resistance issues from exposed contact locations.
Innovation Solution
A safe unlocking machine employing short-distance communication (RFID) for verification between the machine and storage container, eliminating direct electrical contact and ensuring water resistance through a tag with a unique ID and a water-resistant structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical contact verification is used between the safe unlocking machine and currency container, then verification functionality is achieved, but wear occurs at contact locations reducing durability
Solution Approach 1:
The patent replaces the mechanical electrical contact verification system with a non-contact verification method using a tag with unique ID and water-resistant structure. This substitution eliminates physical contact between the safe unlocking machine and currency container, thereby preventing wear at contact locations while maintaining verification functionality.
2Reliability
If electrical contact locations are exposed to the exterior for verification, then verification access is enabled, but water resistance is compromised
Solution Approach 1:
The patent replaces the exposed electrical contact verification system with a non-contact verification method using a tag with unique ID and water-resistant structure. This substitution allows verification access to be enabled through electromagnetic communication while keeping the tag enclosed within the water-resistant currency container, thereby preventing water ingress.
3Reliability
If a tag with unique ID and water-resistant structure is used for verification, then water resistance is maintained and wear is prevented, but device complexity increases
Solution Approach 1:
The patent implements a self-service verification system where the tag with unique ID and water-resistant structure autonomously provides verification functionality. The tag is integrated into the currency container and automatically communicates with the safe unlocking machine without requiring additional external verification devices or complex mechanical interfaces, thereby limiting the increase in device complexity.

AI summary
A safe unlocking machine includes a currency container that may be moved into and out of a container unit. The currency container includes a coin inlet, a bill inlet, and a lock-incorporated shutter that opens and closes a tag. When the shutter is operated to open, RFID wireless verification is performed between an antenna located in the container unit and the tag of the currency container. When predetermined conditions including accomplishment of the RFID verification are satisfied, rotation of a receiver handle is permitted. When the receiver handle is rotated once, a safe main body of a safe, which is located in the safe unlocking machine, is solely moved rearward. The currency in the safe main body falls down due to its own weight and is stored in the currency container.
