Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing personal safety devices that dispense chemical irritants, such as pepper spray, are ineffective in situations where the victim is alone and unable to receive immediate assistance due to the lack of nearby help.

Innovation Solution

A smart personal safety device equipped with a separable wireless data communication module that can transmit an emergency signal via a mobile computing device when the actuation mechanism is activated, allowing for simultaneous dispensing of a chemical irritant and alerting third parties for assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a personal safety device dispenses chemical irritant only, then the device remains simple and portable, but the victim cannot alert third parties for assistance when alone

Engineering Contradiction:

Improveability to alert third partiesVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into a body component and a separable wireless data communication module. The module can be detached from the body and includes its own actuation mechanism, allowing independent operation for alerting third parties without compromising the chemical irritant dispensing function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wireless data communication module serves multiple functions: it can be attached to the body for integrated operation, detached for independent use, and provides both alert signaling and actuation capabilities. This multi-functionality resolves the contradiction between simplicity and versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the wireless data communication module is integrated into the body, then the device structure is unified, but the module cannot be actuated independently when separated

Engineering Contradiction:

Improveindependent actuation capabilityVSAvoidseparable structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wireless data communication module is extracted as a separate, detachable component from the body. This extraction allows the module to be operated independently when separated from the body, while the body retains its chemical irritant dispensing function.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If the device relies on nearby help, then the situation remains simple, but the victim is vulnerable when no help is immediately available

Engineering Contradiction:

Improveemergency assistanceVSAvoidresponse time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The device establishes a wireless communication link with a remote receiver that provides feedback about the emergency situation. The system sends alert signals to third parties who can then respond to the emergency, creating a feedback loop that improves reliability and reduces response time.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The wireless data communication module acts as an intermediary between the victim and third parties. It transmits emergency signals through a mobile computing device to reach help, enabling assistance even when the victim is alone and no help is immediately visible.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Smart personal safety device, system, and method. A personal safety device for dispensing a chemical irritant includes a body for receiving a product cannister, a first actuation mechanism for dispensing product from a product cannister received within the body, and a wireless data communication module coupled to the body for wirelessly transmitting a triggering signal to a remote receiver when the first actuation mechanism is actuated to dispense product from a product cannister received within the body. The wireless data communication module is separable from the body. The wireless data communication module includes a second actuation mechanism configured to actuate the data communication module when the wireless data communication module is separated from the body. The personal safety device can be incorporated into a personal safety system that can send an emergency alert signal to third parties when the chemical irritant is dispensed.
