Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to accurately identify individuals occupying seats in vehicles, leading to generic settings and limited personalized experiences, as existing methods rely on radio keys and lack precise location-specific identification.
Innovation Solution
A method that correlates the movement of a mobile terminal device with the occupation of a location using sensors, allowing for precise assignment of identification to a seat, enabling personalized services and settings adjustments based on user-specific data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radio key identification is used for seat settings, then seat position adjustment is enabled, but identification accuracy deteriorates because the same key is used by multiple people
Solution Approach 1:
The identification system is segmented into multiple independent identification sources: radio key identification, mobile terminal identification, and sensor-based location identification. Each identification method operates independently and can be combined to improve overall accuracy. The mobile terminal's movement data is segmented into discrete position measurements that are correlated with seat occupancy events.
Solution Approach 2:
The mobile terminal acts as an intermediary between the user and the seat identification system. By tracking the mobile terminal's movement and correlating it with seat occupancy sensors, the system indirectly identifies which user occupies which seat without requiring direct user input or compromising multi-user compatibility.
2Measurement precision
If sensor-based location detection is implemented, then location-specific identification is improved, but device complexity increases
Solution Approach 1:
The mobile terminal serves multiple functions: it provides identification data, tracks user movement, and correlates with sensor data to determine seat occupancy. This multi-functionality reduces the need for dedicated specialized devices, thereby limiting the increase in system complexity while maintaining high location detection accuracy.
Solution Approach 2:
The system uses the user's own mobile terminal, which they already carry and use, to provide identification and location tracking services. The mobile terminal's existing sensors (accelerometers, gyroscopes, GPS) are leveraged for tracking movement, eliminating the need for additional dedicated tracking devices and reducing overall system complexity.
3Measurement precision
If movement correlation method is used for identification, then personalized service accuracy is improved, but processing time increases
Solution Approach 1:
The system continuously tracks and stores the mobile terminal's movement data and position information in advance. When a seat occupancy event occurs, the correlation process simply compares the current sensor data with pre-recorded movement patterns, significantly reducing processing time compared to analyzing movement from scratch.
Solution Approach 2:
The system uses feedback from seat occupancy sensors to trigger correlation checks only when relevant events occur (e.g., when a seat is occupied or vacated). This event-driven approach avoids continuous correlation processing, reducing overall processing time while maintaining identification accuracy.

AI summary
What is disclosed is a method for associating an identification stored in a mobile terminal with a location, particularly a seat, comprising: reception of a piece of information that indicates a first time at which a previously unoccupied location is occupied by a person, the occupancy of the location being sensed by means of a sensor; reception of a piece of information that indicates a second time at which the movement of the mobile terminal makes it possible to infer that, if the mobile terminal were carried by a person, the person carrying the terminal would occupy a location, the movement being sensed by means of a sensor in the mobile terminal; establishment of a relationship between the first time and the second time; reception of the identification; association of the identification with the location.
