Solution Overview

Problem

Existing security systems require significant installation effort and disruption due to the need for local electrical connections between security devices and a control hub, and they face power consumption limitations when maintaining wireless connections.

Innovation Solution

A battery-powered security response device that establishes a cellular communications channel with a server, eliminating the need for a locally installed control hub and optimizing power consumption by using a power saving mode that limits cellular modem activity to necessary periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a battery-powered security device maintains a local wireless connection to a control hub, then connectivity and real-time communication are improved, but power consumption increases significantly

Engineering Contradiction:

ImproveconnectivityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The security device uses periodic action by establishing the cellular connection only during specific events (intrusion detection, system arming/disarming) rather than maintaining it continuously. The modem is activated periodically to check for intrusions and transmit alerts, then goes into sleep mode, significantly reducing power consumption while maintaining necessary connectivity functionality.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts its communication behavior based on operational state. The cellular connection is established dynamically when needed (intrusion detected, system armed) and deactivated when not needed (system disarmed, no intrusions). This dynamic on/off switching of the cellular modem allows the device to adapt its power consumption to actual operational requirements.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a locally installed control hub with electrical connections is used, then system reliability and real-time control are improved, but installation complexity and disruption increase

Engineering Contradiction:

Improvesystem reliabilityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the control hub functionality from the local premises and relocates it to a remote server. Instead of requiring a local control hub with electrical connections, the security device communicates directly with a remote server via cellular network. This extraction eliminates the need for complex local infrastructure while maintaining system reliability through cloud-based processing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system replaces the mechanical/electrical connection system (wires, electrical connections to control hub) with a wireless cellular communication system. The physical infrastructure of electrical wiring is substituted by cellular radio frequency communication, dramatically simplifying installation while maintaining connectivity and control capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A security response device is capable of being held in a communications mode or a power saving mode. In the communications mode, it is capable of sending a security threat message to a base station and of receiving a response. In the power saving mode, it is capable of detecting security threats but not performing communication functions. Detection of a security threat causes the device to exit the power saving mode and enter the communications mode.
