Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current QR code applications require different QR codes for each activity or product, leading to increased publicity costs and low utility as QR codes become obsolete after their designated deadline, preventing reuse and timely updates.

Innovation Solution

An information processing system that communicates with mobile devices through a network, using a register module to record event data, a determining module to identify and install necessary application programs, and a transmitting module to deliver messages corresponding to QR codes, allowing for updates and reuse of QR codes without re-registration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different QR codes are registered for each activity or product, then consumers can acquire specific information of different activities or products, but publicity cost increases

Engineering Contradiction:

Improveinformation accuracyVSAvoidpublicity cost

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements a universal QR code system where a single QR code can serve multiple activities and products. The server stores multiple event data sets associated with the same QR code, allowing one QR code to function across different promotional activities, product campaigns, and time periods, thereby eliminating the need to create and print multiple different QR codes

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameters (event data) associated with a QR code dynamically on the server side rather than creating new QR codes. By modifying the event data parameters such as activity information, product details, and promotional content in the database, the same QR code can be reused for different activities without physical replacement

Inventive Principle:

Principle #35Parameter changes

2Reliability

If QR codes are updated after deadline, then message page can be refreshed, but QR codes usually cannot be reused and utility is low

Engineering Contradiction:

Improvemessage timelinessVSAvoidQR code reuseability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system implements dynamic event data that can be updated on the server at any time. The event data associated with QR codes is not static but can be modified, extended, or refreshed based on activity duration, promotional periods, or new product launches, allowing QR codes to remain valid and useful beyond initial deadlines

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables continuous useful action of QR codes by allowing event data to be extended and updated. Instead of QR codes expiring after a fixed period, the system maintains their validity by updating the associated event data on the server, ensuring continuous utility for both consumers and marketers

Inventive Principle:

Principle #20Continuity of useful action

3Quantity of substance

If a fixed QR code is used for multiple activities, then publicity cost decreases and utility improves, but message timeliness and accuracy may be compromised

Engineering Contradiction:

Improvepublicity costVSAvoidmessage accuracy

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The server acts as an intermediary between the QR code and the consumer's mobile device. When a consumer scans a QR code, the server receives the request, retrieves the current event data from its database, and transmits the appropriate message content dynamically. This intermediary mechanism ensures that even though the QR code is fixed, the message delivered is always current and accurate

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback through the server's ability to receive and process QR code scan requests in real-time. Each scan triggers a server response that retrieves the latest event data, ensuring the message reflects the most current activity or product information. This feedback loop maintains message accuracy despite using a reusable QR code

Inventive Principle:

Principle #23Feedback

AI summary

An information processing system includes a register module, a determining module, and a transfer module. The register module is configured to store event data corresponding to a specific QR code. The determining module is configured to obtain the event data, and to communicate with a mobile device, so as to determine whether application programs on the mobile device includes a first application program which is corresponding to any one of the event data. If yes, the determining module transmits launch information to make the mobile device lunch the first application program. If not, the determining module transmits install information to make the mobile device install the first application program. The transmitting module is configured to transmit a message corresponding to the first application program to the mobile device, so that the first application program launched by the mobile device displays the message.
