Presence Check Using Activation Group Data Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for reminding users of missing portable electronic devices often require unnecessary constructive measures, such as installing switches or user interaction, and can generate undesired alarms due to unsuitable activation events.
Innovation Solution
A method and device that utilize noncontact readable data carriers, where data carriers are allocated to check and activation groups, allowing for detection and activation of a presence check only when specific conditions are met, eliminating the need for additional measures and reducing false alarms by linking the presence check to defined conditions like direction of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activation events are based on constructive measures like installing switches or setting timers, then the presence check can be activated, but the device complexity increases and user convenience decreases
Solution Approach 1:
The system uses the data carrier reading means already present in portable electronic devices to automatically detect and read data carriers without requiring users to install additional switches or interact with timers. The device serves itself by utilizing existing capabilities to perform the activation function.
Solution Approach 2:
Data carriers act as intermediaries between the physical objects and the electronic device. Instead of requiring direct interaction with switches or timers, the system uses data carriers to mediate the activation process, simplifying the user interface and reducing complexity.
2Reliability
If the presence check is executed constantly, then all missing objects are detected, but undesired alarms are generated frequently
Solution Approach 1:
Instead of constant checking, the system performs presence checks periodically or event-driven based on data carrier detection. The check is activated only when a data carrier from the activation group is detected, converting continuous operation into periodic action to reduce false alarms.
3Object-generated harmful factors
If data carriers are allocated to check and activation groups, then false alarms are reduced, but the system complexity increases
Solution Approach 1:
Data carriers are pre-alloated to check groups and activation groups before use. This preliminary classification allows the system to automatically determine when to perform presence checks and which objects to monitor, reducing false alarms without requiring complex real-time decision logic.
4Reliability
If additional constructive measures are installed on devices, then the presence check can be activated, but the ease of manufacture decreases
Solution Approach 1:
The system uses the existing data carrier reading means in portable electronic devices for multiple purposes - both for its original function and for activating presence checks. This multi-functionality eliminates the need for additional construction measures, maintaining ease of manufacture while achieving reliable activation.

AI summary
The data carriers (T I, T2, T3, T4) of those objects (1, 2, 3, 4) whose presence is to be checked, are allocated to a check group (ÜG), in a method of checking the presence of objects characterized by noncontact readable data carriers, wherein each noncontact readable data carrier can be identified uniquely or in groups. Data carriers (T1 to T6) are detected by data carrier reading means (5) and it is detected whether at least one of the detected data carriers (T1 to T6) is allocated to an activation group (AG). If at least one of the detected data carriers (T4, T5) is allocated to the activation group (AG), the presence check is activated, while it is checked during the presence check whether all the data carriers (T1 to T4) allocated to the check group (ÜG) are detected by the data carrier reading means (5) and, if not, an alarm signal (AL) is transmitted.
