Solution Overview
Problem
Existing air conditioners struggle to vary airflow speed effectively, making it difficult to simulate natural airflow patterns.
Innovation Solution
An air conditioner system that includes a blower with adjustable vertical and horizontal airflow direction vanes and a fan motor with varying rotation frequency, controlled by a human detection sensor to direct airflow naturally across a human body, simulating natural airflow patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If airflow direction vanes are used to vary blowing air direction, then airflow direction control is improved, but airflow speed variation capability deteriorates
Solution Approach 1:
The patent applies dynamics by making the fan motor rotation frequency variable rather than fixed. The control section dynamically adjusts the rotation frequency of the fan motor based on operational requirements, enabling both airflow direction control (through vanes) and airflow speed variation (through variable rotation frequency). This resolves the contradiction by making the system adaptable rather than static.
Solution Approach 2:
The patent changes the parameter of fan motor rotation frequency from a fixed value to a variable parameter that can be adjusted by the control section. By varying the rotation frequency parameter, the system achieves airflow speed variation while maintaining the airflow direction control function, thus resolving the technical contradiction between direction control capability and speed variation capability.
2Device complexity
If fixed rotation frequency fan motor is used, then device simplicity is improved, but natural airflow simulation capability deteriorates
Solution Approach 1:
The system transitions from a static fixed-speed motor to a dynamic variable-speed motor controlled by a control section. This dynamic control enables the fan motor to simulate natural airflow patterns by varying rotation frequency, achieving adaptability for natural airflow simulation while accepting increased device complexity through the addition of control electronics.
Solution Approach 2:
The patent varies the rotation frequency parameter of the fan motor to simulate natural airflow patterns. By changing this parameter dynamically rather than maintaining a fixed value, the system achieves versatility in airflow simulation while the control section manages the complexity of parameter adjustment.

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.
