Room air conditioner with movable side fan units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners lack precise control over airflow direction and movement, resulting in inefficient temperature distribution within a room, which can lead to uncomfortable temperature environments.
Innovation Solution
The air conditioner incorporates a main unit with a heat exchanger and paired fan units that blow room air to control the direction and movement of cooled or warmed air, utilizing independent blower fans and adjustable fan units to optimize airflow distribution, allowing for targeted temperature enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional air conditioners use natural convection for airflow direction control, then the structure remains simple, but the temperature distribution efficiency deteriorates
Solution Approach 1:
The patent divides the airflow control system into multiple independent fan units positioned at different locations (front, rear, left, right sides of the air outlet). Each fan unit can be independently controlled to create multiple airflow streams that work together to achieve comprehensive temperature distribution throughout the room, resolving the contradiction by segmenting the control function across multiple simple units rather than one complex mechanism
Solution Approach 2:
The patent employs adjustable fan units that can change their operational state and positioning to dynamically control airflow direction and distribution patterns. This dynamic capability allows the system to adapt to different room conditions and achieve efficient temperature distribution without requiring a permanently complex mechanical structure
2Length of moving object
If air outlets are positioned at higher locations, then the device installation is simplified, but the airflow reach and coverage deteriorate
Solution Approach 1:
By segmenting the airflow generation into multiple fan units positioned at different locations around the air outlet, the system can create airflow streams that extend further horizontally from the elevated position, compensating for the height disadvantage and achieving greater overall coverage area
Solution Approach 2:
The patent transitions from single-direction vertical airflow to multi-dimensional airflow distribution by positioning fan units on multiple faces (front, rear, left, right) of the air outlet, creating a three-dimensional airflow pattern that expands coverage in horizontal dimensions while maintaining elevated installation benefits

Function Achieved in This Case
This solution enables efficient and comfortable temperature control by directing airflow to desired locations, ensuring that both cool and warm air reach farther areas effectively, even with reduced flow rates, thereby enhancing the overall room temperature environment.
Implementation Method 1
a heat exchanger generating a cool air or a warm air forming an airflow running out of the air outlet
Implementation Method 2
a pair of fan units disposed on opposite sides of the air outlet, the fan units being configured to suck a room air and to blow the room air

AI summary
An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.
