Solution Overview

Problem

Existing access control devices face high power consumption and logistical challenges in updating authorized credentials, requiring frequent network queries and manual administrator intervention.

Innovation Solution

An access control system with a data storage device and access control device that store and update local and master credential databases, allowing for automatic updates when a new authorized electronic credential is presented, using a transceiver for communication and reducing the need for continuous network activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the access control device queries a central server each time an unrecognized credential is presented, then the system maintains up-to-date credential information, but power consumption increases due to frequent network communicator activation

Engineering Contradiction:

Improvecredential information accuracyVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by having the mobile device transmit credential data to the access control device in advance. This eliminates the need for the access control device to query the server frequently, as the credential information is already available locally, thus reducing power consumption while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mobile device acts as an intermediary between the central server and the access control device. It retrieves credential information from the server and delivers it to the access control device, eliminating the need for the access control device to directly communicate with the server, thereby reducing its power consumption

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If an administrator visits access control devices to update authorized credential data manually, then system updates are performed, but logistical requirements and time consumption increase

Engineering Contradiction:

Improveupdate process simplicityVSAvoidupdate time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The access control device performs self-service by automatically receiving and storing credential data from mobile devices without requiring administrator intervention. The system updates itself autonomously, eliminating the need for manual administrator visits and significantly reducing update time

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Credential data is prepared and transmitted in advance by the mobile device before the access control device needs it. This preliminary action allows the device to update its credential database automatically without waiting for administrator intervention, reducing both time and logistical requirements

Inventive Principle:

Principle #10Preliminary action

AI summary

An access control system including a data storage device configured to store a master credential database having a plurality of master identifiers and master status codes, an access control device having a local credential database including a plurality of local identifiers, and an electronic credential including a credential identifier. The access control device is configured to receive the credential identifier from the electronic credential, to determine whether to perform an update based upon the local status code associated with the local identifier of the credential identifier, and to update data in the local credential database with data in the master credential database by way of communication with the data storage device in response to the determining.
