Solution Overview

Problem

Existing alert notification systems often require the involvement of first responders for non-life-threatening situations, which may not be necessary, and do not effectively alert closer, non-professional responders such as family members or caretakers.

Innovation Solution

A personal alert system comprising a mounting base with a microcontroller, light emitting diodes, a radio frequency transmitter and receiver, and a speaker, programmed to simulate a rotating light pattern and audible alerts, allowing for communication with closer responders and potentially activating them for non-emergency situations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If first responders are notified for all emergency conditions, then life-or-death situations are addressed, but non-life-threatening situations waste first responder resources and time

Engineering Contradiction:
Improveemergency response reliabilityVSAvoidfirst responder response time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The alert system segments emergency conditions into different categories (life-threatening vs. non-life-threatening) and routes notifications to appropriate responders accordingly. The system divides the response function between first responders for critical emergencies and personal alert systems for less severe situations, eliminating unnecessary first responder deployment while maintaining reliable emergency response where needed.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a personal alert system is used for non-life-threatening situations, then closer responders can be notified, but the system must differentiate between emergency and non-emergency conditions

Engineering Contradiction:
Improvealert system usabilityVSAvoidsystem classification complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The personal alert system automatically classifies and routes alert conditions based on pre-programmed criteria without requiring manual intervention. The system self-determines whether a situation warrants first responder involvement or can be handled by personal responders, simplifying user operation while managing classification complexity through automated decision-making algorithms.

Inventive Principle:
Principle #25Self-service

3Illumination intensity

If rotating light patterns are used to simulate emergency vehicle lights, then visibility and attention-grabbing capability are improved, but the system must accurately represent emergency severity

Engineering Contradiction:
Improvelight visibilityVSAvoidemergency severity information
Core Design Contradiction:
Illumination intensityVSLoss of information

Solution Approach 1:

The system uses different light colors and patterns to convey the severity level of the emergency condition. Critical emergencies display red rotating light patterns similar to emergency vehicles, while less severe conditions use different color schemes or patterns. This visual differentiation maintains high visibility through rotating patterns while preserving information about emergency severity through color and pattern variation.

Inventive Principle:
Principle #32Color changes
