Solution Overview

Problem

Current physical access control systems require different physical badges for multiple building sites, even if they have different access system providers, making it inconvenient for users to access multiple locations.

Innovation Solution

A system that uses mobile devices to manage and distribute mobile credentials, allowing users to access multiple building sites by configuring the device to receive user credentials, selecting designated facilities, and transmitting requests to administrators for access, with the mobile device acting as a digital access card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical badges are used for access control at multiple building sites, then security authorization can be enforced, but users must carry different physical badges for each location, reducing convenience

Engineering Contradiction:
Improvesecurity authorizationVSAvoidconvenience of access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mobile device serves as a universal access credential that can be used across multiple building sites with different access system providers. The system provisions facility access credentials to the mobile device that work with various access control systems, eliminating the need for multiple location-specific physical badges while maintaining security authorization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system creates digital copies of facility access credentials and stores them in the mobile device. Instead of requiring physical badges, the system provisions digital credential representations that replicate the access functionality across different facilities, allowing users to access multiple locations using a single mobile device.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If different physical badges are issued for each building site, then access control can be customized per location, but the system complexity increases due to multiple credential types

Engineering Contradiction:
Improvelocation-specific access controlVSAvoidnumber of credential types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile device functions as a universal credential holder that can store and present multiple facility access credentials. The system provisions credentials from different access system providers into a single mobile device, allowing location-specific access control to be maintained while reducing the number of separate credential types the user must manage.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mobile device acts as an intermediary between the user and multiple access control systems. It stores facility access credentials from different providers and presents the appropriate credential when accessing a specific facility, simplifying the interaction between the user and multiple location-specific access control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If users request access to new facilities, then access can be granted securely through administrator approval, but the process requires multiple steps and communication channels

Engineering Contradiction:
Improvesecure access grantingVSAvoidaccess request processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements an automated feedback loop where access requests are electronically submitted and routed to the appropriate administrator through the mobile device. The administrator receives the request, approves or denies it, and the system automatically provisions or denies the facility access credential without requiring separate communication channels or manual processes.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Users can initiate access requests through their mobile device, and the system automatically manages the credential provisioning process. Once approved, the facility access credential is automatically provisioned to the user's mobile device without requiring manual distribution or additional user actions, reducing processing time while maintaining secure administrator approval.

Inventive Principle:
Principle #25Self-service

AI summary

Methods and systems for managing facility access credentials for two or more facilities are disclosed. The method may include electronically receiving a user request to gain access to a designated facility of the two or more facilities and electronically receiving user information related to a user that is making the user request. A facility access credential from a group of facility access credentials that are assigned by a third-party credential issuer may be obtained and linked to the user information and the designated facility. The obtained facility access credential for use in gaining access to the designated facility may be activated resulting in an activated facility access credential and a notification transmitted to the user notifying the user of the activated facility access credential.
