Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need to mitigate the issue of lost or forgotten User Equipment (UE) associated with vehicles, as people often experience stress when they cannot locate their devices, which contain valuable information.

Innovation Solution

A method and system that compares the position of the User Equipment (UE) with the vehicle's position, determining the degree of match and informing the user of the UE's location, thereby reducing the risk of leaving the device behind.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the user manually tracks their UE position, then they can locate their device, but this increases the user's time and effort expenditure

Engineering Contradiction:

ImproveUE location accuracyVSAvoidtime to locate UE

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service by automatically comparing the UE's position with the vehicle's position and notifying the user without manual intervention. The vehicle system autonomously performs position tracking, comparison, and alert generation, eliminating the need for users to manually track their devices while maintaining high location accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring position data and providing real-time notifications to users when their UE is left behind. The system compares positions, determines mismatches, and sends alerts back to the user, creating a closed-loop feedback mechanism that automatically resolves location tracking without user effort.

Inventive Principle:

Principle #23Feedback

2Reliability

If the system continuously monitors position data, then it can detect when UE is left behind, but this increases energy consumption

Engineering Contradiction:

ImproveUE loss preventionVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system employs periodic action by monitoring position data at specific intervals rather than continuously. Position comparisons are performed at defined checkpoints (e.g., when vehicle door is closed, when vehicle moves a certain distance), reducing energy consumption while maintaining reliable detection of UE left behind through strategically timed position checks.

Inventive Principle:

Principle #19Periodic action

3Measurement precision

If the system provides detailed position information to the user, then the user can locate their UE precisely, but this increases the complexity of the system

Engineering Contradiction:

Improveposition matching accuracyVSAvoidposition comparison system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts only the essential position comparison functionality needed to determine if UE is left behind. It focuses on comparing coarse position data (vehicle position vs. UE position) rather than providing full detailed tracking, extracting the minimum necessary information to solve the problem while keeping the system simple.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The embodiments herein relate to a method performed by a system for handling position of a UE (110) associated with a vehicle (100). The system obtains the UE's (110) position and the vehicle's (100) position and compares the UE's (110) position with the vehicle's (100) position. The system determines a degree of match of the compared positions, and informs a user (105) of the UE (110) of the degree of match.
