Solution Overview
Problem
Conventional systems for controlling air-conditioning apparatuses struggle to accurately reflect user thermal sensation without requiring remote controller operation, leading to discrepancies between estimated and actual thermal sensations due to constant metabolic rate assumptions.
Innovation Solution
An apparatus control device that includes a metabolic amount measurement device, a control content storage unit, an input unit, a calculation unit, a correction unit, and a metabolic amount storage unit, which calculates and corrects thermal sensation using real-time metabolic data and historical changes, allowing for precise control of heating-cooling combination apparatuses without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the metabolic amount is assumed as a constant value for estimating thermal sensation, then the control system becomes simple, but the accuracy of thermal sensation estimation deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a static constant metabolic amount assumption to a dynamic metabolic amount that varies over time. The metabolic amount is now updated based on detected thermal sensation feedback, allowing the system to adapt to changing user conditions while maintaining control simplicity through automated feedback loops.
Solution Approach 2:
The patent implements feedback by using the detected thermal sensation to update the metabolic amount in subsequent estimations. The detected thermal sensation serves as feedback that refines the metabolic amount parameter, creating a closed-loop system that continuously improves estimation accuracy without increasing operational complexity for the user.
2Ease of operation
If the remote controller operation is required for controlling air-conditioning apparatus, then the control precision is high, but the ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the air-conditioning apparatus to automatically adjust its operation based on detected thermal sensation and calculated metabolic amount. The system serves itself by autonomously determining appropriate control actions without requiring user intervention, thereby maintaining control accuracy while dramatically improving ease of operation.
Solution Approach 2:
The patent replaces the mechanical remote controller operation with an automated sensing and control system. Instead of requiring manual remote control operations, the system uses thermal sensation detection and metabolic amount calculation to automatically determine control actions, substituting physical interaction with intelligent automation.
3Measurement precision
If the metabolic amount is updated frequently based on real-time detection, then the thermal sensation estimation accuracy improves, but the loss of time for data processing increases
Solution Approach 1:
The patent applies periodic action by updating the metabolic amount at specific intervals based on detected thermal sensation changes rather than continuously. This periodic update approach maintains estimation accuracy by refreshing data when meaningful changes occur, while avoiding unnecessary processing during stable conditions, thus reducing overall data processing time.

AI summary
An apparatus control system includes a metabolic amount measurement device measuring a metabolic amount, and an apparatus control device controlling a heating-cooling combination apparatus. A control content storage unit stores thermal sensations and control contents of the heating-cooling combination apparatus. The metabolic amount measured by the metabolic amount measurement device is inputted to an input unit. A metabolic amount storage unit stores a history of the metabolic amount inputted to the input unit before. A calculation unit calculates the thermal sensation using the metabolic amount inputted to the input unit. A correction unit corrects the thermal sensation calculated by the calculation unit using the history of the metabolic amount stored in the metabolic amount storage unit. An apparatus control unit controls the heating-cooling combination apparatus according to a control content stored in the control content storage unit in association with the thermal sensation corrected by the correction unit.
