Home Controller Environmental Query for Remote Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in remotely controlling home units due to a lack of awareness about the home environment's conditions, leading to potential unintended operations.
Innovation Solution
A controller that acquires environmental parameters and transmits them to a terminal device before executing remote control requests, ensuring user confirmation and enhancing safety by querying the user before executing commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control operation is enabled without environmental parameter confirmation, then ease of operation is improved, but reliability deteriorates due to unintended operations
Solution Approach 1:
The system performs preliminary acquisition and transmission of environmental parameters (temperature, humidity, air quality, etc.) before executing the remote control operation. This allows the user to confirm the current home environment state beforehand, preventing unintended operations while maintaining ease of remote control.
Solution Approach 2:
The system provides feedback to the user by transmitting environmental parameter data from the home to the terminal device. This feedback loop enables the user to make informed decisions about whether to proceed with the remote control operation, thereby improving reliability without compromising operational convenience.
2Reliability
If environmental parameters are transmitted before remote control, then reliability is improved, but loss of time increases due to additional confirmation steps
Solution Approach 1:
The system transmits only the necessary environmental parameters (temperature, humidity, air quality) that are most relevant to the user's decision-making, rather than all possible data. This partial action approach provides sufficient information for safety confirmation while minimizing the time required for data transmission and user review.
3Loss of information
If query data containing environmental parameters is transmitted, then information completeness is improved, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: acquiring environmental parameters from sensors, processing control requests, transmitting query data with environmental information, and executing control operations. This multi-functionality consolidates the system structure, reducing overall device complexity while maintaining complete environmental information transmission.

AI summary
A controller in an energy management system is configured to acquire environmental parameters indicating an environment within a home. The controller is configured to receive a request from a terminal device installed outside the home for remotely operating a unit installed in the home such as an air-conditioning system. The controller is configured to transmit to the terminal device query data containing the acquired environmental parameters, and a query on whether to control the unit according to the request, when receiving the request. The controller is configured to control the unit based on a response to the query from the terminal device.
