Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems for small areas are often overly complex and expensive, requiring multiple sensors and communication paths that can be vulnerable to power attacks and communication disruptions.
Innovation Solution
A security system utilizing low power wide area network (LPWAN) technology, where wireless sensors detect threats and communicate through a network of low power devices to a cloud application, which sends alarm messages to a central monitoring station and user devices, reducing equipment complexity and costs, and providing robust communication paths resistant to disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security systems use multiple sensors and communication paths, then threat detection reliability is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the complex local control panel and multiple communication paths from the security system, replacing them with simple wireless sensors that directly communicate threats to a remote monitoring service. This extraction of complexity while maintaining detection reliability is achieved by removing unnecessary intermediate components and using a cloud-based monitoring architecture.
Solution Approach 2:
The patent introduces a remote monitoring service as an intermediary between sensors and response authorities. This intermediary handles the complex communication routing, authentication, and alert dissemination functions, allowing the local security system to remain simple while maintaining reliable threat detection and response capabilities.
2Reliability
If conventional security systems use multiple communication paths, then communication reliability is improved, but vulnerability to power attacks increases
Solution Approach 1:
The patent replaces traditional wired communication systems with wireless communication technology. This substitution eliminates physical connection points that could be targeted by power attacks or physical tampering, while maintaining communication reliability through wireless protocols that can operate over various distances and environmental conditions.
3Reliability
If conventional security systems use local control panels, then local alarm capability is improved, but equipment cost and complexity increase
Solution Approach 1:
The patent implements self-service by eliminating the need for expensive local control panels and professional installation. Wireless sensors can be easily deployed and configured, with the monitoring service automatically handling alert processing and communication with response authorities. This self-service approach reduces equipment costs while maintaining alarm capability.
Solution Approach 2:
The patent replaces physical local control panels with virtual monitoring functionality provided by a remote monitoring service. The control panel functions are copied and executed in the cloud, eliminating the need for expensive hardware while maintaining the same alarm capability and response functions.
