Solution Overview

Problem

Existing air guiding devices in air conditioners struggle to effectively straighten airflow under different working conditions, often hindering airflow when rotated, which affects air output and temperature adjustment.

Innovation Solution

An air guiding device with a rotatable air guiding part equipped with a flow straightening grid on at least one side, allowing the grid to rotate and straighten airflow as the air guiding part changes direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the air guiding device rotates to change guiding angle, then the airflow direction can be adjusted to different positions, but the fixed grid cannot effectively straighten the airflow under different working conditions and may hinder airflow

Engineering Contradiction:

Improveairflow direction adjustmentVSAvoidair output

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies the dynamics principle by making the grid rotatable to match the rotation of the air guiding device. The grid is connected to the air guiding device through a rotating connection structure, allowing the grid to dynamically adjust its orientation according to the guiding angle. This ensures the grid remains effective at straightening airflow regardless of the air guiding device's rotation position, thereby maintaining high air output while providing versatile airflow direction control.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the grid is fixed at the air outlet, then the structure is simple, but the grid cannot effectively straighten airflow under different working conditions

Engineering Contradiction:

Improvestructural simplicityVSAvoidflow straightening effect

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent transforms the fixed grid into a dynamic, rotatable grid that can adapt to different working conditions. The grid is connected to the air guiding device via a rotating connection, enabling it to change orientation according to the guiding angle. This dynamic design maintains structural relative simplicity while dramatically improving the flow straightening effect under various operating conditions.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the grid is fixed, then the device complexity is low, but the grid may hinder airflow blown from certain angles

Engineering Contradiction:

Improvedevice structureVSAvoidairflow obstruction

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates airflow obstruction by making the grid rotatable. The grid's orientation is dynamically adjusted to match the air guiding device's rotation angle, ensuring the grid always faces the correct direction to guide airflow smoothly. This prevents the grid from blocking airflow at certain angles, as the grid automatically reorients itself according to the working conditions.

Inventive Principle:

Principle #15Dynamics
