Solution Overview

Problem

Existing access control methods, such as those using electronic keys with stored authorization information, are difficult to update and pose risks when keys are lost or misplaced, especially in geographically distributed settings or where access is infrequent.

Innovation Solution

A method where access to an object is controlled by a locking system that requires the presence of a generic mobile element, which does not store authorization information, and instead relies on an authorization carrier element to verify and provide the necessary information, ensuring that the generic mobile element's loss does not compromise security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authorization information is stored in an electronic key, then access control can be implemented, but updating authorization information becomes difficult and security risks increase when keys are lost

Engineering Contradiction:
Improveaccess control securityVSAvoidauthorization information update capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system divides the access control functionality into two separate components: a generic mobile element (without authorization information) and an authorization carrier element (containing authorization information). This segmentation allows the authorization information to be updated independently in the authorization carrier element without affecting the mobile element, resolving the contradiction between maintaining security and enabling easy updates.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The authorization information is extracted from the mobile element and placed in a separate authorization carrier element. This extraction ensures that the mobile element cannot compromise security even if lost, while the authorization carrier element can be updated independently to provide adaptability for changing access requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If a key with stored authorization information is used, then access verification can be performed, but the loss or misplacement of the key creates security risks

Engineering Contradiction:
Improveaccess verificationVSAvoidsecurity risk from lost key
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The authorization information is extracted from the mobile element and stored in a separate authorization carrier element. This separation ensures that if the mobile element is lost, the authorization information remains secure in the carrier element, eliminating the security risk while maintaining ease of access verification through the combined system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The authorization carrier element acts as an intermediary that provides authorization information to the locking element through the mobile element. This intermediary structure allows the mobile element to function as a simple trigger without containing sensitive data, reducing security risks while maintaining operational ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If electronic keys with stored authorization data are used, then access control is possible, but the system complexity increases for managing distributed access

Engineering Contradiction:
Improvedistributed access managementVSAvoidkey management system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments authorization management by separating the mobile element from the authorization carrier element. This allows centralized management of authorization information in the carrier element while keeping mobile elements simple and generic, reducing the complexity of managing distributed access across multiple locations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The generic mobile element is designed to be universal and can be used with multiple locking elements across different locations. Combined with the authorization carrier element that contains location-specific authorization information, this provides versatile distributed access management without requiring different keys for each location, simplifying the overall system.

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

AI summary

The invention relates to a method (600) for controlling an access regime to an object, wherein a locking element (2) can be assigned to the object, wherein access to the object can be granted by the locking element (2) depending on a verification of electronic authorization information, wherein a prerequisite for granting access, in particular for carrying out the verification of the electronic authorization information, is the presence of a generic mobile element (1) at the location of the locking element (2).According to the invention, the authorization information is contained in an authorization carrier element (3) which is present at the location of the locking element (2) in addition to the locking element (2) and the generic mobile element (1), and/or wherein the generic mobile element (1) does not contain the authorization information during a period that precedes the presence of the generic mobile element (1) at the location of the locking element (2) and adjoins the presence of the generic mobile element (1) at the location of the locking element (2).
