Communication Device Power Loss Alert via Pre-stored Message
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices in electrical installations face disruptions in remote supervision and control due to power losses, as they rely on the electrical installation for power and cannot efficiently send alert messages during power failures.
Innovation Solution
A communication device that detects power loss by measuring voltage and interrupts non-essential functions to conserve energy, sending a pre-recorded alert message via a communication link using an energy reserve, such as a capacitor, to inform remote users of the power fault.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device continues to operate all functions during power loss, then it can maintain normal communication operations, but the energy reserve depletes too quickly and cannot send the alert message
Solution Approach 1:
The device pre-constructs and stores the alert message in memory before power loss occurs, so that when power is lost, the message is already ready to send without requiring energy-intensive construction during the power outage. This preliminary preparation resolves the contradiction by enabling reliable message transmission while minimizing energy consumption during the critical power loss period.
Solution Approach 2:
The device extracts and isolates the essential function of sending the alert message from the complete set of communication functions. By selectively maintaining only the message transmission function while suspending other non-essential operations, the device achieves reliable alert transmission with minimal energy consumption from the reserve.
2Loss of information
If the communication device constructs the alert message after power loss, then the message can be customized with current status information, but the construction process consumes too much energy and time
Solution Approach 1:
The device prepares the alert message template and inserts relevant status information before power loss occurs. This preliminary construction ensures the message contains accurate, up-to-date information while avoiding the energy and time cost of constructing the message after power loss, when energy reserves are limited.
Solution Approach 2:
The device creates a copy of the alert message with embedded status information and stores it in memory. This copied message can be directly transmitted without further processing, preserving information accuracy while eliminating the need for energy-intensive message construction during power loss.
3Adaptability or versatility
If the communication device maintains all functions during power loss, then it can handle unexpected situations dynamically, but the response time is delayed due to energy management constraints
Solution Approach 1:
The device performs preliminary detection of power loss conditions and pre-prepares the alert message before complete power failure occurs. This advance preparation eliminates delays that would otherwise occur during the power loss event, enabling immediate message transmission while maintaining the ability to adapt to different power loss scenarios.
Solution Approach 2:
The device skips the intermediate step of message construction and validation that would normally occur during operation, rushing directly to transmitting the pre-prepared alert message. This skipping of non-critical steps reduces transmission delay while maintaining sufficient adaptability to handle the power loss situation.
