Solution Overview

Problem

Conventional air conditioners have limited control over the direction and volume of air discharge, leading to inefficient energy use and discomfort as discharged air often directs towards people, potentially causing health issues.

Innovation Solution

An air conditioner design featuring a front panel divided into rotatable first and second panels, with rotating units that allow for independent or simultaneous rotation of these panels to control the direction and volume of air discharge, using drive motors and guiding mechanisms to adjust the angle of air stream discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the front panel is moved forward by a drive unit to discharge heat-exchanged air, then air discharge function is achieved, but control over air stream direction and discharge volume is limited

Engineering Contradiction:
Improvecontrol over air stream directionVSAvoidpanel structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The front panel is divided into multiple segments: a first panel that rotates about a first axis, a second panel that rotates about a second axis, and a center panel. This segmentation allows independent control of different air discharge directions while maintaining a relatively simple overall structure, resolving the contradiction between operational control and structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control by allowing the first and second panels to rotate about different axes independently. This dynamic configuration enables continuous adjustment of air discharge direction and volume without requiring complex mechanical linkages, achieving ease of operation with moderate structural complexity.

Inventive Principle:
Principle #15Dynamics

2Productivity

If only a relatively small portion of the air conditioner is used for discharging conditioned air, then the structure is simple, but a lot of energy is necessary for air conditioning the room

Engineering Contradiction:
Improveair discharge coverageVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

By dividing the front panel into multiple rotatable segments, the system can distribute conditioned air across different directions and areas of the room simultaneously. This increases the effective discharge coverage without requiring a larger single discharge opening, thereby improving productivity while maintaining energy efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the discharge parameters by adjusting the rotation angles of different panels independently. This allows optimization of air discharge patterns to cover larger room areas efficiently, increasing productivity without proportionally increasing energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If air is discharged straight from the air conditioner into the room towards people's heads or feet, then the discharge structure is simple, but it decreases the comfort of people and may make them sick

Engineering Contradiction:
Improveuser comfortVSAvoidair discharge control mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dynamic rotation capability of the first and second panels about different axes enables the system to adaptively adjust air discharge directions away from occupied zones. This dynamic control improves user comfort without requiring overly complex mechanisms, as the rotation axes are integrated into the panel structure itself.

Inventive Principle:
Principle #15Dynamics
