Find Innovative SolutionsGenerate Solutions
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 adaptability to power outages deteriorates
Solution Approach 1:
The system dynamically switches between grid power and battery power modes, and between primary and bypass communication paths based on real-time conditions. The manager resource adjusts its operation mode (full operation vs. low-power mode) based on power availability, enabling the system to adapt to varying power conditions while maintaining reliability.
Solution Approach 2:
The system changes operational parameters based on power availability. When grid power is available, the system operates at full capacity. When battery power is detected, the system transitions to low-power mode with reduced functionality, allowing continuous operation while adapting to power constraints.
2Adaptability or versatility
If battery backup is used for power outages, then adaptability to power outages is improved, but duration of action deteriorates due to rapid battery depletion
Solution Approach 1:
The system uses periodic wake-up cycles where the manager resource enters low-power sleep mode and periodically wakes to check for grid power availability and communicate with the remote server. This periodic operation significantly extends battery life compared to continuous operation, while maintaining the ability to detect and respond to power outages.
Solution Approach 2:
The system automatically detects power source availability and switches between operational modes without user intervention. The manager resource monitors battery status and grid power conditions, autonomously transitioning between full-power and low-power modes to maximize battery utilization during outages.
3Reliability
If primary communication path is used, then communication reliability is improved under normal conditions, but reliability during power outages deteriorates
Solution Approach 1:
The manager resource acts as an intermediary that selects between primary and bypass communication paths based on power availability. When grid power is available, data flows through the primary path (in-home router). When power outage is detected, the manager resource automatically routes data through the bypass path (cellular network), ensuring continuous communication reliability.
Solution Approach 2:
The communication architecture dynamically switches between primary and bypass paths based on real-time power conditions. The system monitors the availability of the in-home router and automatically transitions to the cellular bypass path when the primary path becomes unavailable due to power outage, maintaining communication reliability.
4Productivity
If manager resource operates continuously, then productivity is improved, but use of energy deteriorates
Solution Approach 1:
The manager resource implements periodic operation with wake-up cycles during battery power mode. Instead of continuously transmitting data, the system wakes at scheduled intervals to check for data buffers, transmit accumulated data, and return to sleep mode. This periodic operation maintains data transmission functionality while dramatically reducing power consumption during battery-powered operation.
Solution Approach 2:
During battery power mode, the system performs partial action by only executing essential functions (data transmission and power monitoring) while suspending non-critical operations. The manager resource operates at reduced capacity, performing only the minimum necessary actions to maintain security monitoring functionality while conserving battery energy.
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.
