Solution Overview

Problem

There is a need for a simple method to verify the validity of authorization tickets received as SMS or MMS on a mobile phone without requiring expensive or complex equipment, as existing solutions are technically complex and unsatisfactory for visual inspection.

Innovation Solution

A method and system that use a central facility to generate and manage authorization rules, allowing mobile devices to receive and display authorization information via SMS or MMS, enabling verification using a control means that checks the presented authorization against predefined rules without needing special technical aids, utilizing a control film for comparison.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional ticketing systems are used, then authorization control can be implemented, but the cost and technical complexity increase significantly

Engineering Contradiction:

Improveauthorization controlVSAvoidcontrol system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses SMS or MMS messages as simplified copies of traditional authorization tickets. Instead of requiring complex electronic ticketing systems, the authorization information is transmitted as text messages that can be read by any mobile phone, dramatically reducing system complexity while maintaining authorization control functionality

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces mechanical/electronic ticket validation systems with a visual inspection method. Inspectors use control films with optical patterns that can be visually compared against authorization information in SMS/MMS messages, eliminating the need for expensive electronic readers and scanners

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If SMS or MMS messages are used for ticket delivery, then mobile phone compatibility is improved, but the ability to verify authorization visually without special equipment is lost

Engineering Contradiction:

Improvemobile phone compatibilityVSAvoidvisual inspection capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces control films as an intermediary tool for inspectors. These films contain optical patterns and instructions that mediate between the SMS/MMS message on the mobile phone and the inspector's visual inspection, enabling verification without requiring special electronic equipment

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The control films utilize optical effects including color changes and Moiré patterns when viewed under specific lighting conditions. These visual effects provide clear indicators for authorization verification, allowing inspectors to validate tickets through simple visual inspection of the mobile phone display against the control film

Inventive Principle:

Principle #32Color changes

3Ease of operation

If simple visual inspection methods are used, then ease of operation is improved, but security and reliability of authorization verification deteriorate

Engineering Contradiction:

Improveinspection simplicityVSAvoidauthorization verification security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The control films contain pre-prepared optical patterns, verification instructions, and security elements that are created in advance. This preliminary preparation ensures that the visual inspection process maintains high security and reliability without requiring complex real-time processing during the actual inspection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The control films incorporate multiple layers and composite optical structures including transparent and opaque areas, different pattern densities, and security elements. This composite design creates complex verification patterns that are easy to inspect visually but difficult to forge, maintaining security while preserving inspection simplicity

Inventive Principle:

Principle #40Composite materials

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

The method involves framing a rule for determining identification information from personal or device-specific data. A control unit is generated for controlling a presented authorization. The control unit is provided for testing the values of the identification. Another rule determines the other identification information. The authorization of the central mechanism is transmitted to a mobile telecommunication terminal (200) by Multimedia messaging service (MMS). An independent claim is also included for a system for executing an access control method.
