Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-defense mechanisms like pepper spray can be easily taken by attackers, and users often fail to activate emergency apps during incidents, while navigation apps do not provide safest routes in unfamiliar cities.
Innovation Solution
A crime prevention device with a refillable ampule unit, sensors, audio-visual capture, and a central server system that includes machine learning and AI to identify threats, spray irritants, capture evidence, and provide safe routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pepper spray is used for self-defense, then the user can deter attackers, but the attacker can snatch the spray and use it against the user
Solution Approach 1:
The patent introduces a remote activation mechanism as an intermediary between the user and the pepper spray. The spray is activated not by the user directly but by a remote signal from a wearable device or mobile app, allowing the user to trigger the spray without physically holding or accessing it during the confrontation, thus preventing attackers from snatching and using it against them.
Solution Approach 2:
The system enables self-service through automated detection and activation. Sensors detect the attack situation, and the system automatically activates the pepper spray without requiring the user to manually retrieve or operate it, ensuring the spray is always available and cannot be stolen or misused.
2Ease of operation
If users activate emergency apps manually, then they can seek help, but users are not in the position to open the application at the time of incident
Solution Approach 1:
The system performs preliminary actions by pre-configuring emergency response protocols and keeping the activation mechanism readily available on wearable devices or mobile apps. The user sets up their emergency contact information and preferred response protocol in advance, so that when an incident occurs, the system can immediately execute the pre-planned response without requiring the user to manually configure anything during the crisis moment.
Solution Approach 2:
The emergency response system operates autonomously by automatically detecting critical situations through sensors or user-triggered alerts and initiating the appropriate response protocols without requiring continuous user intervention. The system self-manages the emergency communication process, contacting predefined contacts and providing guidance based on pre-programmed instructions.
3Adaptability or versatility
If navigation apps provide routes, then users can reach destination, but present technology does not provide safest route in unfamiliar cities
Solution Approach 1:
The patent integrates multiple functions into a single navigation system that not only provides standard routing but also incorporates safety assessments. The system combines traditional navigation capabilities with crime risk evaluation, real-time situation awareness, and safety recommendations, allowing it to serve both navigation and safety monitoring purposes simultaneously.
Solution Approach 2:
The system continuously monitors the user's location and provides feedback about safety conditions along the proposed route. It receives real-time data about crime rates, police presence, and environmental factors, then adjusts the recommended route or provides safety warnings based on this feedback, ensuring the user receives updated safety information throughout the journey.
