Solution Overview
Problem
Existing air conditioning management systems in manufacturing sites reduce environmental fluctuations but do not address power consumption, potentially degrading manufacturing quality and increasing energy costs.
Innovation Solution
A controller system that optimizes air conditioning operations by determining target temperature and humidity settings based on power consumption data to minimize energy use while maintaining manufacturing quality, using a storage apparatus, setting accepting unit, specifying unit, and air conditioning control unit to adjust settings dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the air conditioning apparatus operation is limited to reduce environmental fluctuations, then the manufacturing quality is maintained, but the power consumption is not reduced
Solution Approach 1:
The system changes the target temperature and humidity parameters dynamically based on manufacturing quality data and environmental fluctuation measurements. By adjusting these parameters within allowable ranges rather than maintaining fixed values, the system achieves both quality maintenance and power consumption reduction
Solution Approach 2:
The control system transitions from static air conditioning operation to dynamic adjustment based on real-time environmental monitoring and manufacturing quality feedback. The target temperature and humidity are continuously optimized based on actual environmental fluctuations and quality requirements
2Use of energy by moving object
If the target temperature and humidity are adjusted to minimize power consumption, then the energy costs are reduced, but the manufacturing quality may degrade
Solution Approach 1:
The system implements a feedback mechanism where manufacturing quality data and environmental fluctuation measurements are continuously monitored and fed back to the control unit. This feedback enables the system to adjust target temperature and humidity settings to maintain quality while optimizing power consumption
Solution Approach 2:
The system pre-establishes allowable ranges for target temperature and humidity based on manufacturing quality requirements before optimization. These predetermined constraints ensure that power consumption minimization does not compromise manufacturing quality

AI summary
A factory is equipped with a manufacturing apparatus (300) installed therein for manufacturing a workpiece whose manufacturing quality changes depending on a temperature inside the factory and a humidity inside the factory. A controller (100) includes a storage apparatus (120) for storing power consumption information (124) indicating a correlation between a target temperature inside the factory, a target humidity inside the factory, and a power consumption of an air conditioning apparatus (200); a setting accepting unit (154) for accepting a setting of an allowable range for a combination of a target temperature and a target humidity indicated by the power consumption information (124); a specifying unit (156) for specifying, from the power consumption information (124), a combination of a target temperature and a target humidity that minimize the power consumption within the allowable range as setting values for the air conditioning apparatus (200); and an air conditioning control unit (158) for controlling the air conditioning apparatus (200) based on the specified setting values.
