Solution Overview
Problem
Conventional air conditioners often result in uncomfortable temperature exposure for users due to high wind speeds and noise, and radiation air conditioners require large panels and incur high installation costs with slow cooling speeds.
Innovation Solution
An air conditioner design featuring a movable door and guide member that allows for varying air discharge methods, including selective opening of air outlet portions and use of a curved surface to control airflow, enabling different wind speeds and directions to enhance user comfort and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the fan RPM is increased to maximize wind velocity and wind volume, then the cooling efficiency is improved, but the noise level increases and user comfort deteriorates
Solution Approach 1:
The air outlet is divided into multiple discrete outlets arranged in different directions. Instead of using a single high-speed fan discharge, the system segments the airflow into multiple lower-speed streams that are distributed across different spatial directions, thereby reducing noise while maintaining overall cooling effectiveness.
Solution Approach 2:
The patent transitions from a single-direction high-velocity airflow to multi-directional airflow distribution. By arranging air outlets in various directions (upward, downward, leftward, rightward), the system adds spatial dimensionality to the cooling approach, allowing effective heat dissipation without requiring high fan speeds that generate noise.
2Productivity
If the fan RPM is increased to maximize wind velocity, then the wind volume is improved, but the user comfort deteriorates due to direct heat exposure
Solution Approach 1:
The air outlet is divided into multiple discrete outlets arranged in different directions. Instead of using a single high-speed fan discharge, the system segments the airflow into multiple lower-speed streams that are distributed across different spatial directions, thereby reducing noise while maintaining overall cooling effectiveness.
Solution Approach 2:
Different regions of the housing have different airflow characteristics. The patent creates localized airflow patterns where each air outlet provides cooling to specific zones, with varying flow directions and velocities tailored to different spatial locations, preventing concentrated high-velocity discharge that causes discomfort.
3Object-affected harmful factors
If a radiation air conditioner is used to condition air without a fan, then the noise is reduced, but the panel size must be large and installation costs increase
Solution Approach 1:
The patent replaces the radiation-type passive airflow system with an active fan-driven multi-directional airflow system. Instead of relying on large panels and natural convection (radiation type), the invention uses a fan to actively push air through multiple directed outlets, achieving similar noise reduction benefits while using a more compact, cost-effective design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The air conditioner effectively varies airflow to prevent direct heat exposure, improving user satisfaction by adjusting wind speeds and directions, while reducing noise and installation costs through efficient airflow management.
Implementation Method 1
a fan configured to suction air to an inside of the housing and move the air toward the air outlet
Implementation Method 2
a guide member configured to be moveable to a first position in which air discharged from the fan is guided to the first portion of the air outlet or a second position in which air discharged from the fan is guided to the second portion of the air outlet
Implementation Method 3
The door may include a curved surface bulging toward the housing, and the curved surface may guide air from the fan to the first portion or the second portion of the air outlet

AI summary
An air conditioner includes a heat exchanger for exchanging heat with air introduced to an inside of a housing and a fan for blowing the air having heat exchanged by the heat exchanger to an outside of the housing, the air conditioner capable of blowing air at various airflows by controlling a door configured to selectively open a first portion and a second portion, different from the first portion, of an air outlet of the housing and controlling a guide member configured to controlling a flow path inside the housing.
