Disaster Information Control for Two-Stage Appliance Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems controlling storage battery charging/discharging in response to disaster prevention information can lead to undesirable situations for users, such as unexpected power disruptions and economic losses, due to immediate switching or charging without user consent.
Innovation Solution
Implementing a two-stage operation for electrical appliances, where a primary operation is initiated upon detection of disaster prevention information and a secondary operation is performed after a prescribed period, allowing users a time window to prepare or cancel the operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system switches from power grid to storage battery immediately upon receiving disaster information, then the storage battery is ensured to be available as an emergency power source, but the user experiences unexpected power disruption and potential economic loss
Solution Approach 1:
The system performs preliminary charging of the storage battery upon receiving disaster information, but delays the actual switching operation. This preliminary action ensures the battery is ready while avoiding immediate disruption to the user's power supply, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The control device acts as an intermediary between the disaster information reception and the power switching operation. It introduces a time delay mechanism that mediates between the need for immediate battery availability and the user's preference for continuous power supply, allowing users to cancel or confirm the switching based on actual disaster conditions
2Reliability
If the system charges the storage battery immediately upon receiving disaster information, then the battery is ready for emergency use, but the user suffers economic loss by purchasing expensive emergency power
Solution Approach 1:
The system performs preliminary charging operations when disaster information is received, but allows users to cancel these operations if the disaster does materialize. This preliminary action approach ensures battery readiness while giving users the flexibility to avoid economic losses by canceling unnecessary charging based on actual disaster conditions
Solution Approach 2:
The system dynamically adjusts the charging operation based on user input and actual disaster conditions. Users can dynamically cancel the charging operation if they determine the disaster warning is false or unnecessary, thus converting a static immediate-charging system into a dynamic one that adapts to real-time conditions to avoid economic loss
3Reliability
If the system performs disaster-prevention-information-associated control immediately, then the storage battery is prepared for emergency power supply, but electronic devices may be temporarily cut off causing restoration work
Solution Approach 1:
The control device introduces a time delay intermediary between receiving disaster information and executing the power switching operation. This intermediary mechanism prevents immediate power disruption to electronic devices while still preparing the storage battery for emergency use, thus resolving the contradiction between reliability and harmful effects

AI summary
The possibility of an undesirable situation happening to a user is reduced in controlling an operation of an electrical appliance in accordance with issued disaster prevention information. An electrical appliance (3) is at least assigned a primary and a secondary operation of a two-stage operation as a disaster-prevention-information-associated operation. A disaster-prevention-information-associated control device (2) instructs the electrical appliance (3) to perform the primary operation in response to a detection of an issuance of disaster prevention information and instructs the electrical appliance (3) to perform the secondary operation after a prescribed period of time has elapsed.
