Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods to accurately identify and manage mobile device usage within vehicles, particularly in real-time, to prevent distracted driving and collect relevant data on vehicle and driver behavior, due to limited technological controls and monitoring capabilities.
Innovation Solution
A system that includes a controller transmitting audio signals to determine the location of a mobile device within a vehicle, using software to process these signals and determine if the device is in the driver or passenger space, and implementing policies to block or limit mobile device use when the vehicle is in operation, while also collecting and transmitting vehicle operational data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile devices are used to provide convenience and enhance worker availability, then connectivity and productivity are improved, but driver distraction and safety risks increase
Solution Approach 1:
The patent introduces a vehicle-based system as an intermediary between mobile devices and drivers. This system monitors mobile device usage, detects driver distraction, and controls vehicle functions accordingly. The intermediary layer enables productivity benefits while mitigating safety risks by automatically managing device usage policies based on detected driving conditions and driver behavior.
2Object-affected harmful factors
If legal restrictions and policies are imposed to control mobile device use, then safety risks are reduced, but enforcement capability and monitoring effectiveness remain limited
Solution Approach 1:
The patent implements a feedback-based monitoring system that continuously detects mobile device usage, determines whether the driver is distracted, and automatically enforces policies by controlling vehicle functions. The system provides real-time feedback to drivers about their usage behavior and automatically adjusts vehicle accessibility based on detected distraction levels, creating a closed-loop control system that enhances enforcement effectiveness.
Solution Approach 2:
The system enables automatic self-monitoring and self-enforcement without requiring external intervention. The vehicle system autonomously detects mobile device presence, determines driver distraction status, and controls vehicle functions based on pre-established policies. This self-service approach eliminates the need for manual enforcement and provides continuous automated monitoring.
3Measurement precision
If driver identification systems are implemented to accurately identify who is driving, then data collection accuracy is improved, but system complexity and implementation cost increase
Solution Approach 1:
The patent leverages the mobile device's existing sensors and capabilities (accelerometer, GPS, microphone, camera) to perform multiple functions including driver identification, distraction detection, and usage monitoring. By making the mobile device itself the identification tool rather than introducing separate dedicated hardware, the system achieves accurate driver identification while minimizing additional complexity.

AI summary
Systems, methods, and devices for determining the location of one or more mobile devices within a vehicle comprising: (a) a controller located within the vehicle and configured to transmit at least two audio signals, a first audio signal directed generally into a driver space within the vehicle and a second audio signal directed generally into a passenger space within the vehicle, and (b) software code stored in memory of the mobile device and having instructions executable by a processor that performs the steps of: (i) detecting the at least two audio signals, (ii) sampling the at least two audio signals for a predetermined period of time; (iii) performing digital signal processing on the sampled at least two audio signals; and (iv) based on the results of the digital signal processing, determining whether the mobile device was located within the driver space of the vehicle during the predetermined period of time.
