Directional Beacon Signal for Secure Electronic Stamp Saving

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional paper-based stamp saving systems are inconvenient and prone to errors, as they require physical submission of cards and can be misused due to non-directional beacon signals, leading to unauthorized stamp savings.

Innovation Solution

An electronic stamp system using a stamper and terminal application that transmits a directional beacon signal with store identification and authentication information, setting a bit value only when the stamper contacts the terminal screen, ensuring secure and accurate stamp saving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a non-directional beacon signal is used for stamp saving, then the terminal can receive the signal easily, but unauthorized terminals can also receive and misuse the signal for fraudulent stamp savings

Engineering Contradiction:

Improvesignal receptionVSAvoidauthorization security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The beacon signal is transformed from a uniform omnidirectional transmission to a directional transmission with concentrated energy in a specific spatial direction. The irradiation structure creates a localized signal field that only the intended terminal can receive, while other terminals in different spatial locations cannot intercept the signal, thus preventing fraudulent stamp savings.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If a paper saving card with ink stamp is used, then the stamp saving process is simple and direct, but the card is inconvenient to carry and prone to being lost or misplaced

Engineering Contradiction:

Improvestamp saving processVSAvoidcard security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The mechanical paper-based stamp system is replaced with an electronic system using beacon signals and terminal applications. The physical act of stamping a paper card is substituted with wireless signal transmission and digital authentication, eliminating the need for physical cards while maintaining the stamp saving functionality and enhancing security through directional signal control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If the beacon signal is transmitted without directional limitation, then the transmission coverage is maximized, but the signal can be intercepted by terminals not intended to receive it

Engineering Contradiction:

Improvesignal coverage areaVSAvoidsignal interception

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The beacon signal transmission is transformed from a uniform omnidirectional transmission to a directional transmission with concentrated energy in a specific spatial direction. The irradiation structure creates a localized signal field that only the intended terminal can receive, while other terminals in different spatial locations cannot intercept the signal, thus preventing fraudulent stamp savings.
