Solution Overview
Problem
Existing air conditioning device control systems fail to effectively manage room temperature for multiple users arriving at different times, often resulting in inappropriate temperatures when users come home, especially considering traffic delays and the need for remote control from away from home.
Innovation Solution
An air conditioning control method that uses navigation devices to estimate the arrival time of multiple users and instruct the air conditioning device to set the room temperature to a target temperature based on the earliest user's arrival time, allowing for automatic adjustment and notification of users about the temperature settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the air conditioning device is controlled by a single user setting timer based on estimated arrival time, then the user can set the room temperature to comfort level by arrival time, but the control becomes inaccurate when arrival time changes due to traffic delays and cannot accommodate multiple users
Solution Approach 1:
The system segments the control function by providing separate navigation devices to each user, allowing independent arrival time estimation for multiple users. The control device receives and processes individual arrival time information from each user's navigation device separately, enabling personalized temperature control settings for each user's arrival.
Solution Approach 2:
The control device is designed with universal functionality to handle multiple users' arrival time information simultaneously. It can receive, store, and process arrival time data from multiple navigation devices, and automatically determine the earliest arrival time to control the air conditioning device accordingly, making the system adaptable to varying numbers of users.
2Reliability
If the air conditioning device is turned on earlier to accommodate traffic delays, then the room temperature can be set to comfort level by arrival time, but energy consumption increases unnecessarily
Solution Approach 1:
The system uses feedback from navigation devices that continuously monitor and update actual arrival time estimates based on real-time traffic conditions. The control device receives updated arrival time information and adjusts the air conditioning device's operation timing accordingly, turning it on only as early as necessary to achieve comfort temperature by the actual arrival time, thereby avoiding unnecessary energy consumption.
Solution Approach 2:
The system dynamically adjusts the air conditioning device's operation timing based on real-time arrival time changes. Instead of using a fixed timer setting, the control device continuously updates the operation timing according to the latest arrival time information from navigation devices, making the system flexible and adaptive to changing traffic conditions while optimizing energy usage.
3Measurement precision
If manual control is required for each user's arrival, then temperature can be adjusted precisely, but user intervention and system complexity increase
Solution Approach 1:
Each user's navigation device automatically estimates and transmits their arrival time to the control device without requiring manual input. The control device automatically processes this information, determines the earliest arrival time, and controls the air conditioning device accordingly. This self-service mechanism eliminates the need for manual temperature adjustments while maintaining precise control based on actual arrival times.
Solution Approach 2:
The navigation devices perform preliminary action by continuously estimating and transmitting arrival time information to the control device before the user actually arrives. The control device uses this advance information to pre-set the air conditioning device's operation timing, ensuring the room reaches comfort temperature by the expected arrival time without requiring last-minute manual adjustments.

AI summary
A navigation device (100) estimates a time when a user utilizing the navigation device (100) comes home, and transmits the estimated expected arrival time to a control device (203) in association with the user identifier of the user. In response to receiving the expected arrival times from a plurality of the navigation devices (100), the control device (203) transmits, to an air conditioner (201), a reservation instruction for setting the room temperature at the home to a predetermined target temperature by the estimated arrival time of the earliest user who is supposed to come home earliest. The air conditioner (201) is turned on in accordance with the transmitted reservation instruction among the users.
