Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary air-conditioning control methods are used in existing building management systems, then each system can maintain its own control logic and compatibility, but it becomes extremely difficult to apply more suitable air-conditioning control methods to systems made by other companies
Solution Approach 1:
The patent introduces a data conversion unit as an intermediary component that translates between proprietary air-conditioning control data formats from different manufacturers and a standardized computational data format. This mediator enables seamless integration and application of suitable control methods across different building management systems without requiring complex custom integration for each system
Solution Approach 2:
The patent creates a universal data conversion mechanism that can handle multiple proprietary data formats from different manufacturers through a single standardized interface. The conversion definition information storage unit stores conversion rules for various manufacturers, enabling one system to universally interface with multiple different air-conditioning control systems
2Ease of operation
If building management systems use standardized data formats, then integration across different systems becomes easier, but proprietary systems lose their unique control capabilities and compatibility
Solution Approach 1:
The patent segments the data format conversion process into distinct functional components: a data acquisition unit that retrieves proprietary control data, a conversion unit that translates the data using stored conversion definitions, and a computation unit that processes the standardized data. This segmentation allows the system to maintain proprietary compatibility while achieving standardization for ease of operation
Solution Approach 2:
The conversion definition information storage unit acts as an intermediary layer that preserves proprietary system compatibility while enabling standardized processing. It stores manufacturer-specific conversion rules that bridge the gap between proprietary formats and standardized computational formats, allowing easy integration without losing proprietary capabilities
3Loss of energy
If advanced air-conditioning control methods are applied to existing systems, then energy conservation and comfort optimization can be achieved, but the proprietary nature of existing systems prevents adoption
Solution Approach 1:
The data conversion unit serves as a mediator that enables advanced air-conditioning control methods to be applied to existing proprietary systems by translating their proprietary data formats into standardized computational formats that advanced control algorithms can process, thereby achieving energy conservation without being blocked by proprietary limitations
Solution Approach 2:
The patent changes the data format parameter from proprietary to standardized through the conversion process, while maintaining the underlying control logic and computational capabilities. This parameter change enables the adoption of advanced control methods that optimize energy consumption and comfort across different proprietary systems

AI summary
An air-conditioning control device includes a conversion definition information storage unit, an air-conditioning control computation unit, and a gateway unit. The conversion definition information storage unit preliminarily stores conversion definition information for converting air-conditioning control original data acquired from an external air-conditioning facility into computational data for performing an air-conditioning control computation or conversion definition information for converting air-conditioning control computation resultant data acquired as a result of the air-conditioning control computation into air-conditioning control data used for air-conditioning control at the air-conditioning facility. The air-conditioning control computation unit performs the air-conditioning control computation based on the computational data, and outputs the air-conditioning control computation resultant data. The gateway unit refers to the conversion definition information to convert the air-conditioning control original data into the computational data or to convert the air-conditioning control computation resultant data into the air-conditioning control data.
