Solution Overview
Problem
Existing air conditioning systems lack adaptive control mechanisms that prioritize authorized device control based on the location and identity of individuals within a target area, leading to inefficient and unoptimized environmental settings.
Innovation Solution
An information output system and device control system that generate and output authorization information based on association information from communications terminals, allowing for adaptive control of air conditioners, illumination devices, and electric locks, ensuring authorized control according to the location and identity of users within specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization control is always given to whoever is present in the room, then the system is simple to operate, but the system lacks security and adaptability to different users and locations
Solution Approach 1:
The system pre-establishes association information between identification information (such as user IDs from communication terminals) and authorization levels for different target areas and devices. This preliminary configuration allows the control mechanism to automatically determine appropriate authorization without real-time complex decision-making, thereby enhancing security while maintaining operational simplicity.
Solution Approach 2:
The authorization information is dynamically generated based on the current user's identification information and their location in target areas. The system adapts authorization levels in real-time according to who is present and where they are located, providing security tailored to specific users and locations without requiring a permanently complex control structure.
2Speed
If the system monitors the entire room continuously to quickly respond to human movement, then the response speed is improved, but the energy consumption and system complexity increase
Solution Approach 1:
Instead of continuously monitoring the entire room, the system uses detection sensors to trigger authorization information generation only when human presence is detected. This partial monitoring approach maintains fast response to human movement while significantly reducing energy consumption compared to continuous full-room monitoring.
Solution Approach 2:
The detection sensor automatically triggers the generation of authorization information when it detects human presence, without requiring continuous system operation. The system serves itself by using the detection event to initiate the authorization process, achieving fast response only when necessary and thereby conserving energy.
3Adaptability or versatility
If the system uses detection sensors to trigger authorization, then the adaptability to user presence is improved, but the device complexity and cost increase
Solution Approach 1:
The system uses communication terminals (such as smartphones) that users already possess for multi-purpose functions: identification, location tracking, and triggering authorization. By leveraging the existing communication terminal's capabilities rather than adding dedicated sensors, the system achieves adaptability to user presence while minimizing additional device complexity and cost.
Solution Approach 2:
The communication terminal acts as an intermediary between the user and the air conditioner system. It provides identification information and location data that trigger authorization information generation, eliminating the need for dedicated detection sensors in the air conditioner itself and thereby reducing device complexity while maintaining adaptability.
Data Source
AI summary
An information output system includes a reception device and a processor. The reception device receives, via wireless communication, identification information or association information from at least one communications terminal to which the identification information is assigned. The association information is information about controllability of a target device associated with a target area where a person who carries the at least one communications terminal with him or her is currently present and is correlated to the identification information. The processor acquires the association information by reference to the information received at the reception device and outputs authorization information based on the association information. The authorization information is information used for enabling authorized control of the target device.
