Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for reducing distracted driving, such as apps that restrict phone usage while driving, are ineffective due to their voluntary nature and inability to distinguish between drivers and passengers, leading to ongoing issues with manual phone interaction while driving.
Innovation Solution
An apparatus using Bluetooth Low Energy (BLE) technology within vehicles to determine the location of occupant communication devices (OCDs) and restrict their usage based on whether they are in the driver zone, by transmitting advertisement signals and receiving scan requests to assess signal strength and determine the device's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voluntary apps are used to restrict cell phone usage while driving, then some phone usage restriction is achieved, but the solution is ineffective because it cannot distinguish between driver and passenger and relies on voluntary compliance
Solution Approach 1:
The patent introduces an infotainment system as an intermediary between the mobile device and the driver/passenger. This system uses Bluetooth Low Energy (BLE) transceivers to communicate with the mobile device and determine its location within the vehicle. The infotainment system acts as a mediator that can enforce usage restrictions based on detected location, eliminating the need for voluntary compliance while maintaining system simplicity.
Solution Approach 2:
The system enables the mobile device to self-report its location by having the device scan for and respond to advertisement signals from multiple transceivers. The mobile device itself participates in determining its location by measuring signal characteristics, reducing the need for complex external tracking infrastructure while improving reliability of location-based restrictions.
2Reliability
If hardware is installed on the vehicle to restrict phone usage, then phone usage can be restricted, but the solution becomes less accessible due to hardware installation requirements
Solution Approach 1:
The patent makes the infotainment system perform multiple functions: it serves as the vehicle's entertainment system while simultaneously acting as the location detection and phone usage restriction system. The existing infotainment system's transceivers are repurposed for BLE communication, eliminating the need for separate hardware installation and making the solution accessible to vehicles with standard infotainment systems.
Solution Approach 2:
The system uses software-based location determination that replicates the functionality of complex hardware tracking systems. By using software to process BLE advertisement signals and determine device location, the patent achieves reliable phone usage restriction without requiring specialized hardware installation, thereby improving ease of manufacture and deployment.
3Reliability
If GPS monitoring is used to detect driving speed and shut down the phone, then phone usage can be restricted during motion, but the solution cannot distinguish between driver and passenger and requires continuous high-power GPS operation
Solution Approach 1:
Instead of using continuous high-power GPS monitoring, the system uses partial action by relying on low-power BLE advertisement signals that are already being transmitted for other purposes. The mobile device only needs to scan for and respond to these existing signals rather than continuously transmitting high-power GPS data, significantly reducing energy consumption while maintaining motion detection capability.
Solution Approach 2:
The system uses the infotainment system's existing transceivers for dual purposes: maintaining normal infotainment functions and simultaneously providing location detection for phone usage restriction. This eliminates the need for dedicated GPS hardware and reduces overall energy consumption by reusing existing communication infrastructure.
4Measurement precision
If BLE advertisement signals are transmitted from multiple transceivers to determine device location, then accurate location detection is achieved, but the system complexity increases
Solution Approach 1:
The mobile device itself performs the work of determining its location by scanning for advertisement signals and measuring their characteristics. The device autonomously processes the signals from multiple transceivers to calculate its position, reducing the complexity of the central system while maintaining high measurement precision through distributed signal measurement.
Solution Approach 2:
The patent uses the mobile device's own scan request signals as an intermediary mechanism for location determination. Rather than requiring a complex centralized tracking system, the mobile device's natural BLE scanning behavior is leveraged to gather location data, simplifying the overall system architecture while achieving accurate location detection through signal strength comparison across multiple transceivers.

AI summary
In at least one embodiment, an apparatus including a controller that is electrically coupled to a plurality of transceivers within a vehicle for enabling bi-directional wireless communication via Bluetooth Low Energy (BLE) between the controller and an occupant communication device (OCD). The controller is further configured to: transmit an advertisement signal indicative of the vehicle being in motion from each transceiver to the OCD via BLE and to receive, at each transceiver, a scan request signal from the OCD via BLE at a first power level. The controller is further configured to determine the location of the OCD in the vehicle in response to receiving the scan request signal at each transceiver at the first power level.
