Handheld Guard Device with Active Warning Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems lack active warning means, making them ineffective in deterring unauthorized intrusions and providing real-time alerts.
Innovation Solution
A portable, hand-held, standalone guard device with active warning means, including lighting, acoustic, and gas warnings, that can operate independently without a stationary power source or external guard systems, allowing for manual or automatic control of warning modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security systems are used, then intrusion detection is provided, but active warning means are lacking making them ineffective in deterring unauthorized intrusions
Solution Approach 1:
The patent combines multiple warning capabilities (acoustic alarm, lighting warning, gas discharge) into a single integrated guard device. This merging of previously separate functions into one portable unit enables comprehensive active warning while maintaining ease of use and portability.
Solution Approach 2:
The guard device is designed with multiple functions: intrusion detection sensors, acoustic warning speaker, lighting warning LED, gas discharge capability, and communication modules. This multi-functionality allows a single device to provide both detection and multiple types of active warnings, resolving the contradiction between reliability and adaptability.
2Ease of operation
If a stationary security system with external guard systems is used, then comprehensive security monitoring is achieved, but portability and ease of deployment are reduced
Solution Approach 1:
The patent divides the security system into a portable handheld unit containing all essential components (sensors, warning means, power supply, communication modules) that can operate independently. This segmentation from traditional stationary systems enables portability while maintaining comprehensive security functionality through integration of multiple subsystems in one unit.
Solution Approach 2:
The guard device is designed as a standalone unit with integrated power supply (rechargeable battery), sensors, and communication capabilities that do not require external guard systems or stationary infrastructure. This self-service design enables portable operation while managing complexity through integrated circuitry and modular components.
3Ease of operation
If manual control of warning means is implemented, then user flexibility is improved, but response time may be delayed
Solution Approach 1:
The device operates in multiple dynamic modes: standby mode for normal operation, alarm mode for intrusion detection with automatic warning activation, and test mode for functionality verification. This dynamic operation allows automatic rapid response when intrusions are detected while maintaining user flexibility for manual control and mode selection.
Solution Approach 2:
The device incorporates communication modules (GSM, WiFi) that provide feedback to remote users about intrusion events and device status. This feedback mechanism enables users to monitor and control the device remotely, combining fast automatic local response with flexible remote user control to resolve the contradiction between response speed and operational flexibility.
