Apparatus control device, apparatus control system, and program for updating apparatus control content based on a skin temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioning control devices fail to reflect individual user preferences for thermal environments, as they rely on fixed correspondence between skin temperature and set temperature, making it difficult to adjust settings without user intervention.
Innovation Solution
An apparatus control device that uses a skin temperature measurement system to adjust the heating-cooling combination apparatus settings based on a dynamically updated correspondence relationship, allowing for user preference adaptation by adjusting control widths in response to feedback on thermal comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a fixed correspondence relationship between skin temperature and set temperature is used, then the control device can automatically control the air-conditioning apparatus without remote controller operation, but the user's individual thermal preference cannot be reflected in the control
Solution Approach 1:
The correspondence relationship between skin temperature and set temperature is changed from fixed to dynamic and adjustable. The system initially uses a default correspondence relationship for automatic control, then allows users to adjust the set temperature via remote controller to learn their thermal preferences. The correspondence relationship is updated based on the difference between skin temperature and actual set temperature adjustments, enabling the system to adapt to individual user preferences while maintaining automatic operation capability.
2Adaptability or versatility
If the correspondence relationship is updated based on user feedback, then user preference can be reflected in the control, but the device complexity increases due to additional update mechanisms
Solution Approach 1:
The system implements a feedback mechanism where the user's actual remote controller operations (set temperature adjustments) are used to update the correspondence relationship. The control device calculates the difference between the skin temperature-based recommended set temperature and the actual set temperature the user selected, then uses this feedback to adjust the correspondence relationship parameters. This allows the system to learn user preferences through their actual behavior while keeping the update mechanism relatively simple.
3Measurement precision
If the control width is increased to reduce over-control or under-control, then thermal comfort accuracy improves, but the system may become less responsive to rapid environmental changes
Solution Approach 1:
The control width parameter is made dynamic rather than fixed. The system adjusts the control width based on the current operating conditions and user feedback. When the system detects that the current correspondence relationship produces large deviations between recommended and actual set temperatures, it adjusts the control width to reduce over-control or under-control. This dynamic adjustment allows the system to optimize between accuracy and responsiveness based on actual performance.

AI summary
An apparatus control system includes a skin temperature measurement device configured to measure a skin temperature, and an apparatus control device that controls a heating-cooling combination apparatus. In the apparatus control device, a storage unit stores a correspondence table (correspondence relationship) between skin temperatures and control contents of the heating-cooling combination apparatus. The apparatus control unit controls the heating-cooling combination apparatus according to a control content stored in the storage unit in association with a first skin temperature that is inputted to an input unit. Thereafter, if a second skin temperature that is newly inputted to the input unit is not included in a comfortable temperature range, the update unit updates the correspondence table stored in the storage unit. In this case, the update unit changes the control content in the correspondence table such that over-control or under-control according to the control content is reduced.
