Solution Overview
Problem
Existing air conditioner systems lack precise control over airflow direction and movement, leading to inefficient temperature distribution and comfort in rooms, especially when trying to target specific areas or individuals.
Innovation Solution
A controller circuit for air conditioners that includes a cooling establishment section, first and second fan controlling sections, and an enclosure attitude controlling section, which uses sensors to direct airflow from multiple outlets to effectively target individuals and areas within a room, allowing for adjustable airflow direction and flow rates to enhance comfort and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple air outlets are used to spread cool or warm air over a wider area, then the temperature distribution in the room is improved, but the control precision of airflow direction deteriorates
Solution Approach 1:
The air outlet system is segmented into multiple independent outlets (first air outlet and second air outlets), each with its own control mechanism. The first air outlet is controlled by first horizontal flaps and first vertical louvers, while the second air outlets are controlled by second horizontal flaps and second vertical louvers. This segmentation allows each outlet to be independently controlled, resolving the contradiction between wide area coverage and precise directional control.
Solution Approach 2:
The system employs dynamic control mechanisms where the attitudes of the first and second enclosures can be changed relative to each other. The enclosure attitude controlling section dynamically adjusts the positions of the horizontal flaps and vertical louvers based on detected airflow conditions, enabling real-time optimization of both coverage area and directional precision.
2Adaptability or versatility
If airflow direction is controlled using horizontal flaps and vertical louvers, then the direction regulation capability is improved, but the device complexity increases
Solution Approach 1:
The control system uses universal control mechanisms where the same type of actuators (horizontal flaps and vertical louvers) are employed for both the first air outlet and the second air outlets. This multi-functional approach allows a single control strategy to manage multiple outlets, reducing overall system complexity while maintaining comprehensive direction regulation capability.
Solution Approach 2:
The control functions for multiple air outlets are merged into a unified enclosure attitude controlling section that coordinates the attitudes of both the first enclosure and second enclosures. This consolidation of control functions reduces the number of independent control systems needed, thereby reducing device complexity while preserving adaptability.
3Device complexity
If the airflow direction is allowed to depend on natural convection after release, then the system simplicity is maintained, but the precision of airflow targeting deteriorates
Solution Approach 1:
The system performs preliminary action by actively controlling the airflow direction at the point of release through the coordinated adjustment of horizontal flaps and vertical louvers in both enclosures. This preliminary directional control ensures that the airflow is precisely targeted from the outset, eliminating the need for complex post-release correction mechanisms and maintaining system simplicity while achieving high precision.

Function Achieved in This Case
The system ensures that cool or warm air is directed precisely to individuals and areas, improving comfort and efficiency by utilizing multiple airflow paths and sensors to manage airflow direction and flow rates, even when individuals move within the room.
