Solution Overview
Problem
Existing air-conditioning control systems face challenges in distinguishing between temporary and persistent needs from occupants, leading to extreme environmental movements and increased energy consumption, as they fail to adequately respond to improving indoor comfort while preventing continuous reports from individual occupants.
Innovation Solution
A need identifying device and air-conditioning controlling system that calculates an environment state variable and dissatisfaction level to differentiate between temporary and persistent needs, using predefined control plans to adjust air-conditioning settings accordingly, thereby preventing extreme environmental changes and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the equipment control uniformly responds temporarily to a need report from an occupant, then the equipment control returns to the original control after a temporary response, but the uncomfortable environment will be improved only temporarily and the occupant must make reports continually over an extended period
Solution Approach 1:
The system introduces feedback by continuously monitoring environmental parameters (temperature, humidity) and comparing them against comfort standards. When deviations are detected, the system automatically triggers control actions without requiring continuous occupant reports, creating a closed-loop control system that reduces reporting burden while maintaining effectiveness
Solution Approach 2:
The air-conditioning system performs self-service by autonomously detecting environmental deviations and executing corrective control actions without human intervention. The system monitors its own performance through environmental sensors and automatically adjusts operations to maintain comfort, eliminating the need for continuous occupant reporting
2Reliability
If the equipment control responds persistently to a need report from an occupant, then the indoor environment is reliably improved, but extreme movements in the indoor environment occur due to continual reports by a specific individual
Solution Approach 1:
The feedback mechanism monitors environmental parameters in real-time and compares them against comfort thresholds. When deviations are detected, control actions are triggered automatically. The system includes feedback loops that prevent extreme movements by adjusting control intensity based on current environmental state, ensuring stable yet effective improvements
Solution Approach 2:
The control system is made dynamic by adjusting its response characteristics based on real-time environmental conditions. The system can switch between temporary and persistent control modes depending on the nature and severity of environmental deviations, allowing flexible adaptation that maintains stability while achieving reliable improvement
3Reliability
If the equipment control responds to continuous need reports from an occupant, then the indoor environment is improved, but unnecessary increases in energy consumption occur
Solution Approach 1:
The feedback system continuously monitors environmental parameters and energy consumption patterns. By detecting when environmental deviations occur, the system triggers control actions only when necessary, avoiding continuous operation and reducing unnecessary energy consumption while maintaining effective environment improvement
Solution Approach 2:
The system changes operational parameters dynamically based on detected environmental conditions. Control actions are adjusted in intensity and duration according to the severity and type of environmental deviation, optimizing energy usage by applying the minimum necessary correction rather than continuous maximum-power operation

AI summary
A need identifying device is provided with a need storing portion that receives, from an informant, a need pertaining to the surrounding environment, an environment state variable controlling portion that calculates an environment state variable for indicating the state of the surrounding environment of the informant based on an environment element measured value collected from a space occupied by the informant, and calculates, from the environment state variable, a dissatisfaction level for the surrounding environment of the informant, and an identification processing portion that identifies, based on the dissatisfaction level, a need from the informant as a temporary need or as a persistent need.
