Solution Overview

Problem

The increasing use of electronic devices in vehicles poses a significant distraction for drivers, leading to dangerous situations, and existing solutions fail to effectively restrict device use while allowing necessary functionalities and accommodating different user needs.

Innovation Solution

A policy enforcement system with a transceiver and application that detects vehicle movement and proximity to the driver, implementing policies to restrict device use, such as disabling certain functionalities, and monitoring device motion to determine when to release these restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If policies are implemented to restrict device use during vehicle operation, then driver safety is improved, but device functionality is limited

Engineering Contradiction:
Improvedriver safetyVSAvoiddevice functionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts device restrictions based on real-time detection of vehicle motion states. When the vehicle is detected to be in motion, restrictions are applied to enhance safety. When the vehicle is detected to be stationary, restrictions are lifted to restore full device functionality. This dynamic adaptation resolves the contradiction by making the restriction policy context-dependent rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of device restrictions based on vehicle motion detection. The policy enforcement application modifies the level of restriction (from full restriction to full access) according to the detected motion state parameter. This parameter-based approach allows the system to optimize both safety and functionality according to real-time conditions.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If device restrictions are applied continuously during vehicle operation, then driver distraction is reduced, but user convenience is worsened

Engineering Contradiction:
Improvedriver distractionVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system transitions from static continuous restriction to dynamic conditional restriction. Restrictions are actively applied only when the vehicle is detected to be in motion, and automatically lifted when the vehicle is stationary. This dynamic approach maintains driver safety during operation while preserving user convenience during parking or idle periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback-based control by continuously monitoring vehicle motion state and using this information to adjust restriction policies in real-time. The policy enforcement application receives feedback from the motion detection mechanism and automatically adjusts the restriction level accordingly, creating a closed-loop system that optimizes both safety and convenience.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If motion detection is used to determine policy release, then accurate trip detection is improved, but system complexity is worsened

Engineering Contradiction:
Improvetrip detection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses a multi-functional approach where the motion detection mechanism serves multiple purposes: detecting vehicle motion state for restriction application, determining trip commencement, identifying trip termination, and triggering policy release. This universal use of motion detection reduces the need for separate detection systems for each function, thereby limiting the increase in system complexity while maintaining high detection accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A computerized method for releasing a set of policies implemented on a network device is disclosed including detecting a speed of the network device is zero mph, initiating a policy release counter and determining a position of the network device has changed prior to the policy release counter satisfying a counting requirement. The computerized method further includes detecting the speed of the network device is greater than zero mph and less than a threshold speed, requesting first and second RSSI values from the transceiver, where the first and second RSSI values correspond to first and second communications transmitted by the network device to the transceiver separated by a delay, comparing the first RSSI value and the second RSSI value, and when the second RSSI value is greater than the first RSSI value, releasing the set of policies implemented on the network device.
