Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for presence detection and event registration, such as those used in contact tracing, require manual interaction and have limitations in detecting infections in cluster event situations where virus transmission occurs over greater distances, and they do not meet high European data protection requirements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual QR code scanning is used for event registration, then data protection requirements are met and user control is maintained, but automation is lost and detection precision in cluster events is reduced
Solution Approach 1:
The patent replaces manual mechanical QR code scanning with automated optical/Wi-Fi based detection systems. Mobile devices automatically detect beacon signals from stationary modules without requiring manual user action, thereby achieving full automation while maintaining detection capability through electronic signal processing rather than mechanical scanning
Solution Approach 2:
The patent introduces beacon messages as an intermediary carrier that transmits ServiceSet identity information between stationary modules and mobile devices. This intermediary enables automated detection by serving as a medium that mobile devices can passively receive and process, eliminating the need for direct manual interaction while preserving data protection through controlled information transmission
2Measurement precision
If direct contact tracking is used, then data protection is maintained, but detection capability in cluster events is insufficient
Solution Approach 1:
The patent segments the detection system into independent stationary modules distributed throughout the event space, each broadcasting its own ServiceSet identity information. This segmentation allows the system to detect multiple simultaneous contacts in cluster events without requiring complex centralized processing, as each module independently contributes to the overall detection capability
Solution Approach 2:
The patent creates a universal detection system where mobile devices can automatically interact with multiple stationary modules using the same beacon message protocol. This multi-functional approach allows a single mobile device to detect presence across various locations and cluster events without requiring different detection mechanisms, thereby managing complexity through standardization
3Productivity
If automated beacon transmission is implemented, then productivity and automation are improved, but data protection risks increase
Solution Approach 1:
The patent extracts only the necessary ServiceSet identity information into the beacon messages, transmitting minimal data required for presence detection. By taking out only the essential location/event identifier and excluding personal or sensitive information, the system achieves fast automated detection while mitigating data protection risks through data minimization
Solution Approach 2:
The patent uses beacon messages as standardized copies of location/event information that can be rapidly transmitted and processed. These standardized message copies enable high-speed automated detection through efficient protocol processing while maintaining data protection, as the copied information contains only public ServiceSet identifiers rather than sensitive personal data

AI summary
A method for presence detection and/or event registration at a location or in a spatial area is proposed by means of information transmission between a stationary short-range radio module and at least one mobile short-range radio module, wherein the stationary short-range radio module transmits several beacon messages, wherein a ServiceSet identity information associated with the stationary short-range radio module is transmitted by means of the beacon messages, wherein the ServiceSet identity information comprises identity information related to the location or spatial area or the event, and wherein the mobile short-range radio module has a software module or an application such that this identity information related to the location or spatial area or the event and transmitted as part of the ServiceSet identity information is recognized as such.wherein the method comprises the following process steps: -- in a first step, the stationary short-range radio module transmits the location-, spatial-, or event-related identity information as part of the ServiceSet identity information, -- in a second step, the ServiceSet identity information, together with the location-, spatial-, or event-related identity information, is received by the at least one mobile short-range radio module and recognized by the software module or application as location-, spatial-, or event-related identity information.
