Solution Overview

Problem

Existing access control systems often require user interaction on mobile terminals for granting access, and they have high energy consumption due to continuous searching for connections.

Innovation Solution

The access control arrangement features a reading module acting as an active central module, managing wireless connections with mobile terminals acting as peripheral devices. This configuration reduces energy consumption by minimizing continuous searching and allows the reading module to selectively connect only authorized and relevant mobile terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile terminal continuously searches for wireless connections, then connection availability is improved, but energy consumption increases

Engineering Contradiction:

Improveconnection availabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent inverts the traditional connection initiation role: instead of the mobile terminal (peripheral device) continuously searching for the reading module (central device), the reading module actively initiates connections to mobile terminals. This role reversal allows the energy-intensive continuous searching function to be eliminated from the mobile terminal, while maintaining connection availability through the central device's active connection management.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The reading module implements periodic connection attempts to mobile terminals rather than continuous searching. The control logic establishes connections at defined intervals or triggered by specific events (such as detecting a mobile terminal in proximity), which reduces energy consumption compared to continuous searching while maintaining adequate connection availability.

Inventive Principle:

Principle #19Periodic action

2Adaptability or versatility

If the reading module connects to all detected mobile terminals, then connection coverage is improved, but security decreases

Engineering Contradiction:

Improveconnection coverageVSAvoidaccess security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary authentication and authorization checks before establishing wireless connections. The reading module evaluates whether a mobile terminal is authorized to connect based on pre-configured access rights, time constraints, and location constraints. This preliminary action ensures that only authenticated devices can establish connections, maintaining security while allowing broad coverage for authorized users.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements location-specific access control where different mobile terminals are granted access rights to different reading modules based on their authorized locations. Each reading module has specific authorization data for particular mobile terminals, allowing the system to provide broad overall coverage while maintaining local security restrictions at each access point.

Inventive Principle:

Principle #3Local quality

3Measurement precision

If user interaction is required on mobile terminal for access granting, then authorization accuracy is improved, but ease of operation decreases

Engineering Contradiction:

Improveauthorization accuracyVSAvoiduser interaction requirement

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system implements automated authentication where the reading module independently verifies authorization tokens and manages connection establishment without requiring user actions on the mobile terminal. The mobile terminal merely needs to be in proximity and have valid authorization data; the reading module handles all authentication and connection management automatically, eliminating the need for users to initiate connections or provide input.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms where the reading module continuously monitors for mobile terminals and automatically responds to authorized devices by establishing connections. The control logic receives signals from mobile terminals, evaluates authorization status, and provides immediate automated feedback by either granting or denying access, eliminating the need for manual user confirmation while maintaining accurate authorization control.

Inventive Principle:

Principle #23Feedback
