Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices face challenges with significant installation disruption and power consumption constraints due to the need for local electrical connections and continuous wireless communication with a control hub, limiting their effectiveness and efficiency.
Innovation Solution
A battery-powered security device capable of establishing a cellular connection without a local control hub, operating in a power saving mode to conserve energy and switching to a communications mode only upon threat detection, using a cellular modem for wireless communication and maintaining a connection through periodic wake-ups and discontinuous receive mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security device maintains a local wireless connection to the control hub continuously, then the device remains responsive and can immediately respond to threats, but the power consumption increases significantly
Solution Approach 1:
The security device employs periodic wake-ups from power-saving mode to check for incoming communications with the control hub. Instead of maintaining continuous connection, the device wakes up at predetermined intervals to transmit status information and receive commands, then returns to sleep mode. This periodic action maintains basic responsiveness while dramatically reducing power consumption compared to continuous operation.
Solution Approach 2:
The device dynamically adjusts its operational state between power-saving mode and communications mode based on threat detection. When a security threat is detected, the device transitions from the low-power sleep state to an active communications state, enabling immediate response. This dynamic state change allows the device to optimize between energy conservation and responsiveness based on actual operational needs.
2Ease of operation
If the security device uses battery power to avoid installation disruption, then installation ease improves, but the capability to maintain continuous wireless connection is limited
Solution Approach 1:
The battery-powered device uses periodic wake-ups to maintain its wireless connection with the control hub. By waking up at predetermined intervals to transmit status and receive commands, then returning to sleep mode, the device manages battery power consumption while maintaining essential communication capability. This approach enables the device to operate continuously on battery power without requiring complex power management systems.
3Adaptability or versatility
If the security device wakes up from power-saving mode to communicate with the control hub, then the device can receive commands and respond to threats, but power consumption increases
Solution Approach 1:
The device implements periodic wake-ups from power-saving mode to establish communication with the control hub. During these brief wake-up periods, the device can transmit status information and receive commands. After communication, the device returns to sleep mode, minimizing the time spent in power-consuming mode while maintaining essential communication adaptability.
Solution Approach 2:
The security device autonomously manages its own power consumption by implementing the wake-up and sleep cycle without external intervention. The device self-regulates its operational state based on internal threat detection and scheduled communication requirements, eliminating the need for continuous external power management while optimizing energy usage.

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. The device holds a record of its arming state, but the authentic record of the device's arming state is held remotely. If the device's local arming state is armed, then the device responds without waiting for an update from the base station. If the device's local arming state is disarmed, then the device does wait for an update from the base station.
