Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If passive air conditioning is used to control indoor air environment, then energy consumption is reduced, but the ability to maintain comfortable temperature for few persons is insufficient
Solution Approach 1:
The system dynamically switches between passive air conditioning mode and active air conditioning mode based on real-time evaluation of comfort indices and environmental conditions. This dynamic operation allows the system to maximize energy savings while maintaining the ability to provide comfortable environments for few persons when needed.
Solution Approach 2:
The system continuously monitors indoor and outdoor environmental parameters, calculates comfort indices, and uses this feedback to determine the optimal air conditioning mode. This feedback mechanism ensures that the system adapts to individual comfort requirements while minimizing energy consumption.
2Manufacturing precision
If complex calculation models are used to determine air conditioning operation, then air environment control accuracy is improved, but system complexity and implementation time increase
Solution Approach 1:
The system segments the air conditioning control into distinct operational modes (passive mode and active mode) with clear decision criteria. This segmentation simplifies the control logic while maintaining accurate environmental control by applying appropriate strategies for different conditions.
Solution Approach 2:
The system uses readily available environmental sensors and standard comfort index calculations rather than complex specialized models. This approach achieves sufficient control accuracy without requiring expensive or complex computational resources.
3Adaptability or versatility
If active air conditioning is used to ensure individual comfort, then comfort for few persons is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts between passive and active air conditioning operation based on real-time evaluation of comfort requirements and environmental conditions. This dynamic operation ensures active air conditioning is used only when necessary for individual comfort, minimizing energy consumption while maintaining adaptability.
Solution Approach 2:
The system continuously evaluates comfort indices and uses this feedback to determine when active air conditioning is truly necessary. This feedback-driven approach ensures active air conditioning is activated only when it provides genuine value for individual comfort, avoiding unnecessary energy consumption.

AI summary
The instruction device according to the present invention is used in an air conditioning system. In a case where evaluation information concerning comfort of an air environment of an indoor space for person(s) in the indoor space corresponds to discomfort and a difference between first data on the air environment of the indoor space and second data on an air environment of an outdoor space is not less than a prescribed value, the instruction device creates setting information to use only a first air conditioning device for causing movement of air between the indoor and outdoor spaces when determining that the comfort can be improved by the first air conditioning device, and creates setting information to use a second air conditioning device for controlling the air environment of the indoor space by consuming energy resource when determining that the comfort cannot be improved by the first air conditioning device.
