Solution Overview

Problem

There is a need for a system that can detect and alert parents or guardians when children or pets are left behind in vehicles or wander beyond designated areas, potentially approaching dangerous items or objects.

Innovation Solution

A wireless alert system comprising a wireless tag and a control device that communicate via Bluetooth, RF, or other protocols, using a motion sensor to detect changes in proximity or movement, triggering notifications to the user via various means such as alarms, texts, or screen changes when the tag and device separate or lose contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wireless alert system is implemented to detect and alert when children or pets are left behind or wander beyond designated areas, then safety monitoring capability is improved, but device complexity and power consumption increase

Engineering Contradiction:

Improvesafety monitoring capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the monitoring function into two separate components: a wireless tag attached to the child or pet, and a control device held by the parent or guardian. This segmentation allows each component to remain simple while the combined system provides comprehensive safety monitoring through proximity detection and motion sensing capabilities.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If motion sensors and proximity detection are continuously monitored to detect vehicle motion and separation events, then detection accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improvedetection accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system employs periodic motion sensing and proximity checking rather than continuous monitoring. The motion sensor periodically detects vehicle motion, and the wireless communication periodically checks proximity between the tag and control device. This periodic operation maintains detection accuracy while significantly reducing power consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

AI summary

An alert system having a first wireless tag; and a control device capable of being in communication with the first wireless tag, wherein when the control device receives a signal from the wireless tag it is an indication of no event, and when the control device does not receive a signal from the wireless tag it is an indication of an even, thus the control device sends a notification to the user.
