Solution Overview

Problem

Existing access control systems require extensive updates to maintain current access data, leading to inefficiencies and increased storage needs in access control devices.

Innovation Solution

An access control method and system that utilizes a mobile device to transmit current access attributes to an access control device, allowing for real-time access control decisions based on rules and instructions, reducing the need for frequent updates and minimizing data storage requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a tabular database is stored in the access control device to perform access checks, then access control functionality is achieved, but extensive updates must be performed regularly to maintain current access data

Engineering Contradiction:
Improveaccess control accuracyVSAvoidupdate frequency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Instead of storing complete access rules in the access control device and updating them frequently, the patent inverts the approach by storing only minimal identification data locally and transmitting full access attributes from the mobile device during each access attempt. This eliminates the need for frequent database updates in the access control device while maintaining accurate access control.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the time-sensitive access attribute data from the access control device's database and relocates it to the mobile device. The access control device retains only static identification information, while dynamic access attributes are transmitted on-demand from the mobile device, eliminating the update burden from the access control system.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a tabular database with large amounts of data is stored in the access control device, then comprehensive access control is achieved, but storage capacity requirements increase

Engineering Contradiction:
Improveaccess control coverageVSAvoiddata storage capacity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent inverts the traditional storage model by placing the bulk of access attribute data in the mobile device's storage rather than the access control device. The access control device stores only minimal identification data, dramatically reducing its storage requirements while the mobile device leverages its larger storage capacity to hold comprehensive access information.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The mobile device acts as an intermediary that bridges the gap between comprehensive access data storage and the access control device's limited storage capacity. It transmits necessary access attributes on-demand, allowing the access control device to maintain versatile access control functionality without requiring large storage capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If access data is updated frequently to maintain current requirements, then access control accuracy is improved, but system complexity and update overhead increase

Engineering Contradiction:
Improveaccess data currencyVSAvoidupdate mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent resolves the contradiction by inverting where update complexity resides. Instead of the access control device requiring complex update mechanisms to maintain current data, the mobile device assumes responsibility for maintaining and updating its own access attribute database. The access control device simply receives and uses the data as transmitted, eliminating update mechanism complexity from the access control system.

Inventive Principle:
Principle #13The other way round (Inversion)
