Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If air diffusion terminals introduce air with swirling movements at high speed to obtain inductive mixing effects and have a throw, then the air distribution range is improved, but the system becomes noisy and causes discomfort to occupants
Solution Approach 1:
The patent applies dynamic air distribution by using adjustable air outlet devices that can modify their orientation and opening angles in response to detected air currents and temperature variations. This allows the system to adaptively control air flow patterns, achieving effective room coverage while maintaining comfortable and quiet operation through real-time adjustments rather than fixed high-speed swirling movements
Solution Approach 2:
The system incorporates sensors that detect air currents and temperature distribution throughout the room, feeding this information back to control mechanisms that adjust the air outlet devices. This feedback loop enables the system to optimize air distribution effectiveness while avoiding excessive speeds and noise by making incremental adjustments based on actual room conditions
2Temperature
If air systems operate in heating mode, then thermal comfort is provided, but thermal stratification occurs causing discomfort and energy inefficiency
Solution Approach 1:
The patent employs dynamic air outlet devices that can adjust their orientation and air flow characteristics in response to detected thermal stratification patterns. When stratification is detected through temperature sensors, the system modifies air distribution patterns to promote mixing and eliminate temperature gradients, thereby maintaining energy efficiency while providing thermal comfort
Solution Approach 2:
Temperature sensors distributed throughout the room provide feedback on thermal stratification conditions to the control system. Based on this feedback, the air outlet devices dynamically adjust their operation to prevent or eliminate stratification, ensuring both thermal comfort and energy efficiency by matching air distribution to actual thermal conditions
3Reliability
If hybrid systems combining air and water-based radiant panels are used, then thermal comfort and air quality are improved, but system complexity and environmental impact increase
Solution Approach 1:
The patent implements air outlet devices that perform multiple functions: air distribution, thermal comfort control, and air quality management through integrated sensors and adaptive control. This multi-functionality eliminates the need for separate radiant panel systems while achieving comparable or superior thermal comfort and air quality outcomes, thereby reducing overall system complexity
Solution Approach 2:
The system combines air handling and thermal comfort functions into a single integrated air distribution system with adaptive control capabilities. By merging what would traditionally require separate air HVAC and radiant panel systems into one unified solution, the patent reduces complexity while maintaining or improving performance in thermal comfort and air quality

AI summary
An air conditioning system serving a room to be treated using a source of conditioned air includes one or more multifunction apparatuses, which are equipped with a plenum, one or more air supply ducts to feed the plenum through one or more inlet openings, and a terminal element for interfacing the one or more multifunction apparatuses to enable the passage of the conditioned air and exchange heat by irradiation and/or convection with the room to be treated. The multifunction apparatuses are arranged into the room to be treated with a vertical or horizontal extension and include regulation systems for varying the distribution of conditioned air in the one or more multifunction apparatuses between the vertical and/or horizontal internal portions of the apparatuses.
