Solution Overview

Problem

Air conditioners face challenges in reducing noise while maintaining air volume, as closer stabilizer placement improves airflow but increases noise, and greater distances decrease airflow, leading to noise and volume loss.

Innovation Solution

The air conditioner design includes a stabilizer with a body and modifier positioned at specific distances from the fan to minimize noise and air volume loss, with the modifier extending further than the body to cover the installation space for part of the fan's rotation, and the distances between these components satisfying certain ratios to optimize performance.

Engineering Contradictions & Design Principles

1Productivity

If the stabilizer is placed closer to the fan, then airflow performance is improved, but noise increases

Engineering Contradiction:
Improveairflow performanceVSAvoidnoise
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The stabilizer is divided into two distinct parts: a body portion and a modifier portion. The body is positioned closer to the fan to optimize airflow, while the modifier extends further outward to reduce noise. This segmentation allows each part to fulfill different functions without compromising the other, resolving the contradiction between airflow performance and noise reduction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the stabilizer are given different spatial characteristics. The body has a first distance from the fan for airflow optimization, while the modifier has a second distance (greater than the first) for noise reduction. This local differentiation of quality allows the stabilizer to simultaneously address both airflow and noise concerns in different local zones.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If the stabilizer is placed farther from the fan, then noise is reduced, but air volume is lost

Engineering Contradiction:
ImprovenoiseVSAvoidair volume
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The stabilizer's body and modifier are segmented to perform different functions. The body maintains proximity to the fan to preserve air volume, while the modifier extends outward to achieve noise reduction. This segmentation enables the system to prevent air volume loss while still reducing noise, resolving the contradiction between these two parameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modifier extends in a different spatial dimension beyond the body, reaching outward to cover the installation space. This dimensional extension allows noise reduction to be achieved without compromising the body's proximity to the fan, thereby maintaining air volume while reducing noise through a different spatial approach.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If the modifier extends further than the body, then noise reduction is improved, but device complexity increases

Engineering Contradiction:
Improvenoise reductionVSAvoidstabilizer structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The body and modifier are merged into a single integrated stabilizer component rather than being separate parts. This merging reduces assembly complexity and structural complexity while still achieving the desired noise reduction through the modifier's extended position. The unified structure simplifies manufacturing and installation compared to separate components.

Inventive Principle:
Principle #5Merging (Combining)
