Problem
Existing alarm systems face limitations when using the public switched telephone network (PSTN) for communication and remote control, due to the sunset of PSTN services and limited capabilities of modern alarm systems.
Innovation Solution
A system that includes a customer terminal and web server, capable of converting instructions between different formats for transmission over various networks, enabling communication and control of alarm systems via modern cellular and broadband networks, including wired and wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If alarm systems use PSTN for communication and remote control, then they can maintain compatibility with legacy systems, but they face service sunset and limited capabilities
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the alarm system and modern communication networks. The gateway converts alarm system signals to data packets suitable for transmission over IP-based networks (cellular, broadband), enabling legacy alarm systems to communicate reliably through modern infrastructure without direct PSTN dependency
Solution Approach 2:
The invention changes the communication parameter from traditional voice-based PSTN signaling to data packet transmission over IP networks. By converting alarm signals into digital data packets, the system adapts to modern network protocols while maintaining service reliability through multiple available communication paths
2Adaptability or versatility
If alarm systems are designed for PSTN communication, then they can operate with traditional infrastructure, but they severely limit the capabilities of modern alarm systems
Solution Approach 1:
The gateway serves as an intermediary that handles the complexity of format conversion and protocol adaptation. It translates between simple alarm system signals and complex network protocols, enabling modern capabilities (remote control, notifications via SMS/email, integration with mobile devices) without requiring the alarm system itself to be complex
Solution Approach 2:
The gateway provides multi-functional communication capabilities including cellular network communication, broadband connectivity, SMS messaging, email notifications, and remote device control. This universal interface enables a single alarm system to access multiple modern communication channels and features
3Adaptability or versatility
If alarm systems convert signals to data packets for modern networks, then they can access cellular and broadband networks, but they require format conversion infrastructure
Solution Approach 1:
The patent merges the alarm system, customer terminal, and gateway functions into an integrated unit. By combining these previously separate components, the conversion infrastructure becomes part of the alarm system itself rather than a separate external device, reducing overall system complexity while maintaining network compatibility
