Solution Overview
Problem
Existing airflow control systems do not allow users to visually recognize the reachable range of airflow, making it difficult to effectively direct and utilize airflow in space zoning applications.
Innovation Solution
An airflow control system comprising an air blower with a cylindrical member, a supplier for functional components, and a lighting fixture that emits directional light aligned with the airflow direction, controlled by a controller to ensure the airflow is directed and its range is visibly indicated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fluid carrier is used to direct airflow to a target spot, then the diffusion of the fluid is reduced, but a person cannot visually recognize the reachable range of the airflow
Solution Approach 1:
The patent applies color changes by introducing a lighting fixture that emits light in the same direction as the airflow. This visual indicator allows persons to recognize the reachable range of the airflow while the fluid carrier maintains its directivity function. The lighting fixture creates a visible representation of the airflow path without altering the airflow's directional stability.
Solution Approach 2:
The patent uses an intermediary approach by introducing light as a mediator between the airflow and the observer. The lighting fixture serves as an intermediary that translates the invisible airflow into a visible form, allowing visual recognition of the airflow range while the airflow itself maintains its directivity through the fluid carrier.
2Length of moving object
If airflow is directed with high directivity to reach distant targets, then the airflow maintains its path, but the reachable range becomes difficult to visually assess
Solution Approach 1:
The lighting fixture emits light that visually marks the reachable range of the airflow, allowing persons to easily detect and assess the distance and direction of the airflow. This solves the difficulty of visual detection while maintaining the long reachable range achieved through directivity.
Solution Approach 2:
Light serves as an intermediary that bridges the gap between the invisible airflow and human visual perception. The lighting fixture translates the extended reachable range of the airflow into a visible indicator, making it easy to detect and measure without compromising the airflow's directivity or range.
3Productivity
If the airflow is supplied with functional components for space zoning, then the effectiveness of airflow distribution is improved, but the system complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated system. The air blower, functional component supplier, and lighting fixture are combined into one unified airflow control system controlled by a single controller. This integration improves the effectiveness of airflow distribution for space zoning while managing system complexity through coordinated operation of combined components.
Solution Approach 2:
The system achieves multi-functionality by combining the airflow generation, functional component supply, and visual indication functions into a single system. This universal design allows the system to perform multiple tasks (airflow distribution, functional component delivery, and visual range indication) simultaneously, improving productivity without proportionally increasing complexity.

AI summary
An airflow control system includes an air blower, a supplier, a lighting fixture, and a controller. The air blower has an outlet port, from which an airflow with directivity is allowed to blow out. The supplier may supply the airflow blowing out from the outlet port with a functional component to be eventually emitted into the air. The lighting fixture may emit light having directivity in a direction aligned with a direction in which the airflow blows out from the outlet port of the air blower. The controller controls the air blower and the lighting fixture.
