Blower Vane and Fan Control for Natural Airflow Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners struggle to vary airflow speed effectively, making it difficult to simulate natural airflow patterns.
Innovation Solution
A blower system with vertical airflow direction vanes and a control section that independently drives these vanes while varying the rotation frequency of a fan, allowing for the generation of airflow patterns similar to those found in nature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a conventional air conditioner with varying vanes is used, then the airflow direction can be varied, but the airflow speed cannot be effectively varied
Solution Approach 1:
The patent applies dynamics by making the fan rotation frequency variable rather than fixed. The control section dynamically adjusts the fan's rotation frequency to vary airflow speed, enabling the air conditioner to simulate natural airflow patterns that change in speed and direction, thereby resolving the contradiction between maintaining operational simplicity and achieving natural airflow simulation.
2Speed
If the fan rotation frequency is varied, then the airflow speed can be changed, but the airflow pattern becomes difficult to control
Solution Approach 1:
The patent merges the control of airflow direction (via vanes) and airflow speed (via fan rotation frequency) into a unified control system. The control section coordinates both the varying vanes and fan rotation frequency variations work together to generate natural airflow patterns, reducing overall system complexity while achieving comprehensive airflow control.
Solution Approach 2:
The control section serves multiple functions: it controls the varying vanes for direction adjustment and simultaneously adjusts fan rotation frequency for speed variation. This multi-functionality allows a single control mechanism to manage both directional and speed aspects of airflow, simplifying the overall control architecture while maintaining sophisticated airflow patterns.
3Shape
If only varying vanes are used, then the airflow direction can be adjusted, but the airflow pattern does not resemble natural airflow
Solution Approach 1:
The patent applies periodic action by varying the fan rotation frequency in a periodic manner to simulate natural airflow patterns. Combined with the varying vanes that periodically adjust direction, this creates airflow that mimics the intermittent and variable nature of natural air movement, thereby enhancing the realism and adaptability of the airflow pattern.

AI summary
A blower and an air conditioner that can generate airflow simulating that in the natural world are provided. The blower and the air conditioner each include: a fan configured to generate blowing air; a pair of vertical airflow direction vanes separated from each other as a left side and a right side on a front side of the fan, the pair of vertical airflow direction vanes causing the blowing air generated by the fan to be let out upward or downward; and a control section configured to drive the pair of vertical airflow direction vanes separately while varying a rotation frequency of the fan. Such configuration of the blower and the air conditioner enables generation of airflow simulating that in the natural world.
