Solution Overview

Problem

Air conditioners face issues with pipe breakage due to resonance phenomena caused by natural frequency alignment of components, leading to increased outdoor unit size and reduced cooling/heating efficiency, as existing methods require elongating and complexly configuring pipes to prevent resonance, occupying unnecessary space.

Innovation Solution

The air conditioner is designed with modularized blocks for the outdoor unit, where each block contains specific control parts, allowing for secure fixation and reduction of secondary vibration sources, thereby preventing pipe breakage and optimizing space usage without the need for extensive piping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pipes are elongated and configured complexly to prevent resonance, then pipe breakage due to resonance is prevented, but the size of the outdoor unit increases

Engineering Contradiction:
Improvepipe durabilityVSAvoidoutdoor unit size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The outdoor unit is divided into multiple modular blocks (first block, second block, third block) that can be independently assembled. Each block contains specific components and control parts, eliminating the need for complex piping connections between components while reducing resonance risks through modular isolation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Modular blocks serve as intermediary units that replace complex pipe networks. The blocks are disposed at specific positions (first channel between oil separator and four-way valve, second channel between outdoor and indoor heat exchangers, third channel between accumulator and compressor) to facilitate refrigerant flow while minimizing resonance transmission paths.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If pipes are elongated and configured complexly to prevent resonance, then pipe breakage due to resonance is prevented, but cooling and heating efficiency is reduced

Engineering Contradiction:
Improvepipe durabilityVSAvoidcooling and heating efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By segmenting the system into modular blocks, the patent reduces unnecessary pipe length and complexity, thereby improving refrigerant flow efficiency and reducing pressure losses that would otherwise occur in complex piping configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using complex pipe configurations to solve resonance problems, the patent inverts the approach by using modular blocks with minimized piping, achieving both resonance prevention and improved efficiency through a different structural paradigm.

Inventive Principle:
Principle #13The other way round (Inversion)

3Volume of stationary object

If modular blocks are used to reduce outdoor unit size, then space is optimized and larger compressors can be used, but device complexity increases

Engineering Contradiction:
Improveoutdoor unit sizeVSAvoidmodular block configuration
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The outdoor unit is segmented into three main blocks with specific component assignments: first block (oil separator, four-way valve, first control parts), second block (outdoor heat exchanger, indoor heat exchanger, second control parts), and third block (accumulator, compressor, third control parts). This segmentation reduces overall unit size while maintaining functional simplicity through standardized modular interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each modular block is designed to perform multiple functions within its structure. For example, the first block houses both the oil separator and four-way valve, while the second block contains both heat exchangers. This multi-functionality reduces the need for separate components and connections, simplifying the overall system despite the modular architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)
