Solution Overview

Problem

Users may be unable to receive timely aid in emergency situations due to reliance on mobile devices that are out of power or signal range, as existing systems like US 10,939,244 B1 do not provide reliable user tracking when out of communication range.

Innovation Solution

An emergency assistance system comprising a position monitoring unit in a mobile device, a user tracking unit in a vehicle, and a multi-access data storage unit, which monitors and stores user position information, allowing the vehicle to perform emergency actions when the user is in an unexpected situation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users rely on mobile devices for emergency communication, then communication capability is improved, but reliability deteriorates when device is out of power or signal range

Engineering Contradiction:
Improveemergency communication capabilityVSAvoidtracking reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a server as an intermediary component that receives position information from both the mobile device and the vehicle. When the mobile device is unavailable, the server can still track the user's location through data from the vehicle's user tracking unit, which monitors the user's position within the vehicle and communicates it to the server. This intermediary server acts as a backup communication channel, ensuring tracking reliability even when direct mobile device communication fails.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements multi-functionality by creating two parallel tracking pathways: one through the mobile device's position monitoring unit and another through the vehicle's user tracking unit. Both pathways feed into the same server, allowing the system to universally track user position regardless of which device is available. This redundancy ensures that emergency assistance can be initiated through either channel, improving overall system reliability.

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

2Reliability

If position information is continuously monitored and stored, then user tracking reliability is improved, but data storage requirements and system complexity increase

Engineering Contradiction:
Improveuser tracking reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex data storage and processing functions from the mobile device and vehicle units, concentrating them in a centralized server. The mobile device's position monitoring unit and the vehicle's user tracking unit are simplified to only capture and transmit position data, while the server handles the heavy lifting of storing, managing, and processing the continuous position information. This extraction reduces the complexity burden on individual devices while maintaining reliable tracking through centralized data management.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of time

If vehicle performs emergency actions based on user position, then emergency response speed is improved, but false alarm risk increases

Engineering Contradiction:
Improveemergency response timeVSAvoidfalse alarm risk
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback mechanisms where the server continuously receives and verifies position information from both the mobile device and the vehicle's tracking unit before triggering emergency actions. The server can cross-validate data from multiple sources, assess the situation, and confirm genuine emergencies before activating vehicle responses. This feedback loop reduces false alarms by filtering out spurious signals while maintaining rapid response to authentic emergencies through pre-configured action protocols.

Inventive Principle:
Principle #23Feedback
