Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insurance providers face challenges in determining appropriate insurance coverage terms for vehicles as existing methods, relying on telematics data and vehicle occupancy, are insufficient to accurately assess risk and driving habits.
Innovation Solution
A system and method that utilize a first device associated with a party in a vehicle, receiving signals from a second device to determine the orientation and location of the first device within the vehicle, allowing differentiation between driver and passenger seats, thereby facilitating more accurate assessment of driving data and insurance pricing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If telematics data and vehicle occupancy information are used to assess insurance risk, then some level of risk assessment can be performed, but the accuracy and reliability of determining appropriate insurance coverage terms is insufficient
Solution Approach 1:
The patent replaces traditional mechanical/sensor-based detection methods with magnetic field-based detection. A magnet is placed in the driver's seat, and a magnetometer in the mobile device detects its position and orientation through magnetic field interactions, enabling non-contact, passive detection of driver presence and device orientation without requiring active sensors in the vehicle.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the driver (or device) and the detection system. The magnet serves as a passive marker that mediates the interaction, allowing the magnetometer to indirectly detect the presence, position, and orientation of the driver's device without direct contact or active transmission from the vehicle side.
2Measurement precision
If the system uses magnetic field interactions to determine device orientation and location, then driver identification accuracy is improved, but the system complexity increases due to requiring multiple devices and signal processing
Solution Approach 1:
The patent extracts the detection function from the vehicle's instrument panel and relocates it to the driver's mobile device. The magnetometer and processing logic are moved to the device itself, while the vehicle only needs to contain a simple passive magnet, significantly simplifying the vehicle's instrumentation while enabling precise location and orientation detection.
Solution Approach 2:
The driver's mobile device performs self-detection and self-processing of the magnetic field signals. The device uses its own magnetometer to detect the magnet's position and orientation, and its own processor to calculate location and orientation data, eliminating the need for complex vehicle-based detection systems and reducing overall system complexity.

Function Achieved in This Case
Enables insurance providers to correlate driving data with the party's role in the vehicle, improving the determination of insurance costs and terms by accurately identifying whether the party is the driver or passenger, thus enhancing risk assessment and pricing accuracy.
Implementation Method 1
receiving, when the second device transmits a signal, an indication of a direction of orientation of the first device, where the indication of the direction of orientation of the first device is affected by the signal transmitted by the second device
Data Source
AI summary
A computer-implemented method for determining an indication of a location of a first device in a vehicle is presented. A determination may be made of when a second device in the vehicle transmits a signal. When the second device transmits the signal, an indication of a direction of orientation of the first device may be determined. The indication of the direction of orientation of the first device may be affected by the signal being transmitted by the second device. The indication of the location of the first device in the vehicle may be determined based on an indication of a direction of motion of the vehicle and the indication of the direction of orientation of the first device. The indication of the location of the first device may include an indication of whether the first device is associated with a driver seat of the vehicle.
