Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power outages can lead to undesirable consequences, such as damage to appliances and harm to devices reliant on them, especially when individuals are not present or unaware of necessary actions to take during a power loss.
Innovation Solution
A device with a processor and storage that determines if power from a secondary source is being or will be received, and executes instructions to perform specific actions regarding the operation of connected apparatuses using this secondary power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring and unplugging of appliances during power outages is required, then energy conservation and appliance protection are achieved, but user convenience and response time deteriorate
Solution Approach 1:
The system enables appliances and devices to automatically detect power source changes and execute protective actions without human intervention. The microcontroller monitors power source status and automatically switches between primary and secondary power sources, protecting connected devices from damage during power outages while eliminating the need for manual user action.
Solution Approach 2:
The system continuously monitors the status of the primary power source and provides feedback to the control mechanism. When the primary power source fails or voltage drops below threshold levels, the system detects this change and automatically activates the secondary power source, ensuring continuous operation of critical devices without requiring user awareness or action.
2Reliability
If automatic power source switching is implemented, then response time and appliance protection improve, but device complexity increases
Solution Approach 1:
The power management system is divided into independent functional modules: a monitoring module that detects power source status, a control module that decides when to switch, and execution modules that perform the switching action. This segmentation allows each component to perform its function simply, reducing overall system complexity while maintaining fast response times through coordinated operation of the modules.
Solution Approach 2:
The system uses a universal microcontroller that can monitor multiple power sources, detect various failure conditions, and control different types of loads. This multi-functional approach consolidates what could be multiple separate devices into a single unit, reducing system complexity while providing comprehensive power management and protection across diverse appliances and devices.

AI summary
In one aspect, a device includes a processor and storage accessible to the processor. The storage bears instructions executable by the processor to determine that power from a secondary power source at least one of is being received and will be received. The instructions are also executable to, responsive to the determination that power from the secondary power source at least one of is being received and will be received, perform a first action regarding operating an apparatus using the secondary power source.
