Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning control systems fail to effectively manage temperature settings for multiple users sharing a single air conditioner, particularly when users return home at different times, leading to inefficient energy use and potential heat shock.
Innovation Solution
An air conditioning control system that includes remote control terminals with position detection and travel speed measurement capabilities, communicating with a server to calculate arrival times and adjust air conditioning settings to ensure a comfortable indoor temperature just before the earliest returning user arrives, thereby minimizing energy consumption and heat shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioning is activated early to prepare for multiple users returning at different times, then comfort for early-arriving users is improved, but energy consumption increases
Solution Approach 1:
The system performs preliminary actions by calculating estimated arrival times of multiple users and activating air conditioning in advance only for the time period necessary until the first user arrives. The control unit determines the earliest arrival time among multiple users and sets the air conditioning to operate from the current time until that specific moment, ensuring comfort is ready when needed without unnecessary extended operation.
Solution Approach 2:
The system dynamically adjusts air conditioning operation based on real-time position data and calculated arrival times of multiple users. The control unit continuously monitors user positions, recalculates estimated arrival times, and adjusts the air conditioning operation period accordingly. This dynamic adaptation allows the system to optimize energy consumption by matching air conditioning operation precisely to the actual earliest arrival time rather than using fixed schedules.
2Use of energy by moving object
If air conditioning is activated late to save energy, then energy consumption is reduced, but heat shock occurs for early-arriving users
Solution Approach 1:
The system performs preliminary calculations of user arrival times based on current position data and travel speed information. By determining the estimated arrival time of the first user in advance, the system activates air conditioning early enough to prevent heat shock while avoiding excessive early activation. The control unit sets the operation end time to coincide with the calculated earliest arrival time, ensuring the indoor temperature is comfortable when the user arrives.
Solution Approach 2:
The system continuously receives position information from user terminals and recalculates estimated arrival times in real-time. This feedback mechanism allows the system to adjust air conditioning operation timing dynamically, ensuring that the air conditioning remains on long enough to prevent heat shock for early-arriving users while turning off promptly after the earliest arrival time to conserve energy.
3Reliability
If air conditioning operates continuously for all users, then comfort for all users is ensured, but energy waste increases
Solution Approach 1:
The system performs preliminary analysis of multiple user schedules by receiving position and travel information from multiple terminals. It calculates the estimated arrival time for each user and determines the earliest arrival time among them. The air conditioning is then operated only until this earliest arrival time, after which it turns off. This preliminary planning eliminates the need for continuous operation, preventing energy waste while ensuring comfort for the first arriving user.
Solution Approach 2:
Instead of providing air conditioning for all users simultaneously or continuously, the system applies partial action by activating air conditioning only for the necessary duration until the first user arrives. This partial operation is sufficient to ensure comfort for early-arriving users while avoiding the excessive energy consumption that would result from continuous operation designed to accommodate all users regardless of their actual arrival times.
4Productivity
If the system calculates arrival times for multiple users, then air conditioning timing is optimized, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions using the same position detection and calculation mechanisms. It receives position information from multiple user terminals, calculates travel speeds, determines estimated arrival times for each user, identifies the earliest arrival time, and uses this information to control air conditioning operation. This multi-functionality allows the system to optimize air conditioning timing for multiple users without requiring separate complex systems for each user.
Solution Approach 2:
The system merges the calculation of multiple users' arrival times into a single integrated process. The control unit receives position data from multiple terminals, calculates each user's estimated arrival time, and determines the earliest arrival time by comparing these values. This merged approach consolidates what could be multiple separate calculation systems into one unified control process, reducing overall system complexity while maintaining the ability to optimize for multiple users.
Data Source
AI summary
An air conditioning control system includes a plurality of remote control terminals and a server. The plurality of remote control terminals each calculates a time required for a user of the remote control terminal to return to a building from outside the building, and transmits information indicating the time required to the server. The server calculates an estimated time when a user who returns to the building first among the plurality of users returns to the building on the basis of the time required, and transmits a command for changing air conditioning setting to an air conditioner in stages from a time when the estimated time is calculated to the estimated time calculated.
