Directional Beacon Stamper with Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper-based stamp saving systems are inconvenient and prone to misuse, as users must physically submit their cards to accumulate stamps, leading to potential loss and malicious use.
Innovation Solution
An electronic stamp system utilizing a stamper device that transmits a directional beacon signal with authentication information to a terminal, which recognizes a pattern of contact ports to ensure legitimate stamp saving through a server, preventing unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a paper-based saving card with ink stamp is used, then the stamp service can be implemented, but the user experiences inconvenience and risk of losing the card
Solution Approach 1:
The patent replaces the physical paper saving card with a virtual copy stored in a terminal device (smartphone, tablet, or computer). The electronic saving card application replicates all functions of the paper card while eliminating physical loss risks. Users can access their saving card information, stamp records, and balance through the application interface, providing both security and convenience.
Solution Approach 2:
The patent substitutes the mechanical ink stamping process with an electronic verification system. Instead of physically stamping a paper card with ink, the system uses optical recognition technology to verify the saving card through the terminal device's camera or sensor, automatically recording stamp information in the database without physical contact or ink transfer.
2Reliability
If a paper saving card is used for stamp accumulation, then the stamp service operates, but the system is vulnerable to malicious and illegal use
Solution Approach 1:
The patent implements a feedback mechanism where the server continuously monitors and verifies stamp accumulation requests. When a stamp is added, the system sends notifications to the user's terminal device, updates the electronic saving card balance in real-time, and maintains audit logs. This feedback loop prevents unauthorized modifications and ensures data integrity, making malicious use difficult while maintaining manageable system complexity through automated verification.
Solution Approach 2:
The patent introduces a server as an intermediary between the stamping process and the saving card system. The server acts as a central authority that verifies authentication information, manages stamp records, and controls the addition of stamps to user accounts. This intermediary layer prevents direct manipulation of saving card data, blocking malicious attempts while keeping the overall system structure organized and maintainable.
3Reliability
If authentication information and directional beacon signal are added to prevent misuse, then stamp security is improved, but the device complexity increases
Solution Approach 1:
The patent leverages the terminal device's existing multi-functional capabilities to handle authentication and verification tasks. The terminal device's camera, processor, and communication modules serve multiple purposes: capturing the saving card image, processing authentication information, communicating with the server, and providing user interface functions. This universal use of existing components achieves enhanced security without significantly increasing the stamper's structural complexity.
Solution Approach 2:
The patent implements self-service authentication where the terminal device automatically performs verification tasks without requiring additional manual intervention. The device's camera automatically captures the saving card, the processor extracts and verifies authentication information, and the system communicates with the server to confirm stamp eligibility. This self-service approach enhances security through automated authentication while minimizing the complexity burden on the stamper device.
