Multi-Outlet Airflow Control Circuit for Room Temperature Zoning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners struggle to finely control airflow orientation and movement, leading to inefficient temperature distribution in rooms, which can result in unpleasant temperature environments.
Innovation Solution
The air conditioner incorporates a structural body with a first wind direction plate and auxiliary housings, along with a control circuit that adjusts the wind direction of both the first and second air outlets to ensure the temperature-adjusted airflow stays within a certain range, using movable components and blower fans to mix indoor and temperature-adjusted airflows effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the airflow orientation is left to natural convention without fine control, then the system structure remains simple, but the temperature environment regulation efficiency deteriorates
Solution Approach 1:
The air outlet is divided into multiple independent air outlets (first air outlet and second air outlets), each equipped with its own wind direction plate. This segmentation allows independent control of airflow from each outlet, enabling fine-grained orientation control without requiring complex centralized control mechanisms.
Solution Approach 2:
The wind direction plates are designed to be movable rather than fixed, allowing dynamic adjustment of airflow orientation. The control circuit can change the posture of wind direction plates in real-time to adapt to different operational requirements, providing flexible airflow control while maintaining relatively simple mechanical structures.
2Productivity
If multiple air outlets are used to improve temperature distribution, then the temperature environment regulation improves, but the control coordination between outlets becomes complex
Solution Approach 1:
The control circuit integrates control of multiple wind direction plates into a unified control system. By coordinating the posture adjustments of different wind direction plates simultaneously, the system achieves effective temperature distribution control without requiring separate complex control mechanisms for each outlet.
Solution Approach 2:
The control circuit monitors the operational state and coordinates the wind direction plates based on actual performance requirements. This feedback mechanism allows the system to automatically adjust the orientation of multiple air outlets to optimize temperature distribution, reducing the need for manual intervention and simplifying overall control.
3Adaptability or versatility
If the wind direction plate posture is fixed, then the manufacturing precision requirements are reduced, but the adaptability to different operational conditions deteriorates
Solution Approach 1:
The wind direction plates are designed with movable capabilities, allowing them to adjust their posture dynamically in response to different operational conditions. This dynamic design provides high adaptability to varying requirements while using standard mechanical components that do not demand extreme manufacturing precision.
Solution Approach 2:
The system changes the orientation parameter of wind direction plates to adapt to different operational conditions. By controlling the posture angle of movable wind direction plates rather than relying on fixed precision-manufactured orientations, the system achieves high adaptability with moderate manufacturing precision requirements.

AI summary
An air conditioner includes a main body unit and an auxiliary housing. The main body unit forms a first air outlet which blows out a cool or warm airflow. The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit controls a second wind direction plate so that a second reference plane PL2 which regulates a wind direction of the second wind direction plate intersects a first reference plane PL1 which regulates a wind direction of a first wind direction plate, on a downstream side of the airflow.
