Solution Overview
Problem
Conventional home security systems face challenges with power consumption and communication during long power outages, as components often require continuous grid power and primary communication paths may fail, leading to rapid battery depletion and disrupted data transmission.
Innovation Solution
A wireless security system with reduced power consumption and redundant communication paths, where a manager resource selectively transmits security data over primary and bypass communication paths, such as 4G/LTE, ensuring continuous data delivery to a remote server even during power failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security system components use continuous grid power, then system reliability is improved, but device complexity and installation difficulty increase due to physical tethering requirements
Solution Approach 1:
The patent replaces the mechanical tethering system (physical power cables and outlets) with a wireless power transmission system using electromagnetic fields. The security components communicate and receive power wirelessly through electromagnetic communication, eliminating the need for physical connections while maintaining system reliability.
2Duration of action of stationary object
If battery backup is used for power outages, then system availability is improved, but battery life is depleted quickly due to continuous power consumption
Solution Approach 1:
The patent implements periodic communication and power transmission cycles where the security components enter low-power states between transmissions. The system activates wireless communication and power reception only when needed, allowing batteries to recharge during idle periods and extend overall operational duration during power outages.
Solution Approach 2:
The patent combines power transmission and data communication into a single wireless electromagnetic channel. This integration allows the security components to receive both operational commands and electrical power through the same wireless interface, reducing overall power consumption by eliminating separate power transmission infrastructure.
3Productivity
If primary communication path is used, then data transmission efficiency is improved, but communication reliability deteriorates during power failures when the path is disabled
Solution Approach 1:
The patent introduces wireless electromagnetic fields as an intermediary medium that can transmit both power and data independently of the primary wired communication infrastructure. When the primary communication path fails due to power outages, the wireless intermediary maintains communication reliability by providing an alternative transmission channel that operates autonomously.
Solution Approach 2:
The patent implements dynamic path selection where the system automatically switches between primary wired communication and wireless backup communication based on real-time availability. The communication interface adapts its transmission medium dynamically, maintaining data transmission efficiency by preferring the wired path when available and seamlessly transitioning to wireless when the primary path fails.
Data Source
AI summary
A security network provides reduced power consumption and more robust communication of messages in comparison to conventional wireless systems. Reducing power consumption as discussed herein ensures that the security system is able to operate for a long duration of time, potentially with minimal or no power from an electrical grid. Additionally, redundant communication paths as discussed herein provide a more robust way of selectively forwarding security data to a remote server. The availability of multiple communication paths ensures that a respective remote target recipient such as a server resource or remote communication device operated by a user can be notified of a trigger event during power failure conditions, such as when certain communication functionality of a security system is disabled.
