Air Blower Assembly and Ducted Air Conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air blower assemblies in air conditioners have a high space occupation rate and complex structure due to the need for independent rotation of multiple air blowers, which complicates the adjustment of airflow direction and increases the overall length of the device, making it difficult to meet diverse user requirements and reducing product competitiveness.
Innovation Solution
A rotatable air blower assembly with collinear rotating axes, where multiple air blowers are sequentially connected and driven by a single apparatus, reducing the need for rotation gaps and simplifying the structure by using a mounting bracket that allows for simultaneous rotation and adjustment of air outlet orientations, thereby reducing the overall length and space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple air blowers are arranged in parallel with independent rotation, then airflow direction can be adjusted, but space occupation rate increases and structure becomes complicated
Solution Approach 1:
Multiple air blowers are merged into a single integrated assembly where they share a common rotation mechanism and collinear rotation axes. The air blowers are connected sequentially along the rotation axis, allowing them to rotate simultaneously as one unit rather than independently, which simplifies the overall structure while maintaining airflow direction adjustability.
Solution Approach 2:
The common rotation mechanism serves all air blowers simultaneously, making the rotation system multi-functional. A single driving apparatus controls the rotation of multiple air blowers, and the shared rotation axis enables collective airflow direction adjustment for all blowers, reducing the need for multiple independent rotation mechanisms.
2Adaptability or versatility
If multiple air blowers are arranged in parallel with independent rotation, then airflow direction can be adjusted, but space occupation rate increases
Solution Approach 1:
The air blowers are merged into a compact linear arrangement along the rotation axis, eliminating the need for lateral spacing that would be required for independent rotation mechanisms. This consolidation significantly reduces the overall volume occupied by the air blower assembly while preserving the ability to adjust airflow direction through collective rotation.
Solution Approach 2:
The air blowers are arranged collinearly along the rotation axis rather than in a parallel configuration, effectively utilizing the axial dimension for compact packaging. This dimensional reorganization allows multiple blowers to be packed more efficiently in space while maintaining rotation capability for airflow direction control.
3Device complexity
If a single driving apparatus drives multiple air blowers, then structure is simplified, but synchronization of rotation must be maintained
Solution Approach 1:
The air blowers are mechanically coupled through the shared rotation axis and common driving apparatus, ensuring that all blowers rotate in unison. This mechanical integration inherently synchronizes the rotation of all air blowers, maintaining reliability without requiring complex control systems, as the collinear arrangement and shared mechanism ensure simultaneous rotation.
