Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operation support systems display power consumption of electrical equipment, then user awareness of power saving is increased, but the system does not effectively correlate operating conditions with weather information leading to inefficient energy usage
Solution Approach 1:
The patent combines weather information (temperature, humidity, weather forecasts) with electrical equipment operation data into a unified display system. The control device integrates multiple data sources including weather data from communication devices and operation data from sensors, merging them into correlated information that shows both environmental conditions and equipment status together, enabling users to see the relationship between weather and power consumption patterns
Solution Approach 2:
The system implements feedback by displaying correlated weather and operation information to users, who then adjust equipment operation based on this feedback. The control device continuously monitors both weather conditions and equipment operation, provides visual feedback through the display device showing the correlation, and enables users to modify operation plans accordingly, creating a closed-loop system that improves energy efficiency
2Productivity
If the system integrates multiple devices including control device, communication device, and sensors to correlate weather information with equipment operation, then energy usage is optimized, but the device complexity increases
Solution Approach 1:
The control device serves multiple functions: it controls electrical equipment operation, receives and processes weather information from communication devices, collects sensor data from temperature and humidity sensors, correlates all this information, and displays results. This multi-functional approach consolidates what could be separate systems into a single universal control unit, managing complexity while maintaining comprehensive functionality
Solution Approach 2:
The control device acts as an intermediary that bridges weather information sources and equipment operation systems. It receives weather data through communication devices, processes this information alongside sensor readings, and generates correlated operation recommendations. This intermediary role simplifies the system architecture by centralizing the correlation logic in one component rather than requiring direct integration between all elements

AI summary
The total electric power that is supplied to a house, the electric power that is consumed by electrical equipment that is used in the house, and electric power that is generated by an electric power generator are automatically displayed together with weather information that indicates the weather every hour. As a result, a user is able to check the amount of electric power consumed by the electrical equipment according to the weather, or check the amount of electric power that is generated according to the weather. Therefore, it is possible to efficiently operate the electrical equipment according to the weather.
