Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input method is used to set height difference, then flexibility in setting is improved, but man-hour and input mistakes increase
Solution Approach 1:
The system enables automatic acquisition of height information for both indoor and outdoor units through sensors and communication modules. The management apparatus automatically calculates the height difference and determines appropriate refrigerant transport capacity settings without requiring manual worker input, thereby eliminating time consumption and input errors while maintaining operational flexibility.
Solution Approach 2:
The patent replaces the manual mechanical input method with an automated information acquisition system using sensors (e.g., atmospheric pressure sensors, GPS) and communication modules. This substitution eliminates the need for workers to manually enter height data, automatically capturing and processing height information to determine refrigerant transport capacity settings.

3Productivity
If fixed height difference setting is used, then setup time is reduced, but adaptability to operation conditions decreases
Solution Approach 1:
The system dynamically adjusts the refrigerant transport capacity settings based on the automatically calculated height difference between indoor and outdoor units. The management apparatus processes the height information and determines appropriate settings that adapt to specific installation conditions, enabling both rapid setup and adaptability to varying operation conditions.
Solution Approach 2:
The patent changes the parameter of refrigerant transport capacity settings based on the measured height difference. The system automatically acquires height information, calculates the height difference, and adjusts the refrigerant transport capacity parameters accordingly, enabling adaptive settings that match specific installation conditions while maintaining fast setup speed.
4Loss of time
If height difference is not properly set, then manual input work is reduced, but cooling and heating capacity maintenance fails
Solution Approach 1:
The system enables automatic acquisition of height information for both indoor and outdoor units through sensors and communication modules. The management apparatus automatically calculates the height difference and determines appropriate refrigerant transport capacity settings without requiring manual worker input, thereby eliminating time consumption while ensuring proper capacity maintenance through accurate automated calculations.
Solution Approach 2:
The patent replaces the manual mechanical input method with an automated information acquisition system using sensors (e.g., atmospheric pressure sensors, GPS) and communication modules. This substitution eliminates the need for workers to manually enter height data, automatically capturing and processing height information to determine refrigerant transport capacity settings, thereby ensuring both time efficiency and reliable capacity maintenance.

AI summary
Provided is a height difference setting system capable of setting a transport capacity of refrigerant in an appropriate state. A height difference setting system (1) is constituted by a plurality of components. Information is communicated between the components, and accordingly a height difference between an outdoor unit (8) and an indoor unit (9) that constitute an air conditioner (7) installed on or in a building (6) is set. The height difference setting system (1) includes components that function as an outdoor unit height information obtaining unit (2), an indoor unit height information obtaining unit (3), a height difference setting unit (4), and a transport capacity adjusting unit (5). The outdoor unit height information obtaining unit (2) and the indoor unit height information obtaining unit (3) obtain outdoor unit height information indicating a height of an installation place of the outdoor unit (8) and indoor unit height information indicating a height of an installation place of the indoor unit (9), respectively. The height difference setting unit (4) sets a height difference between the outdoor unit and the indoor unit on the basis of the outdoor unit height information and the indoor unit height information. The transport capacity adjusting unit (5) adjusts a transport capacity of refrigerant to be transported from the outdoor unit to the indoor unit on the basis of the height difference set by the height difference setting unit (4).
