Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axial blowers face challenges in achieving high efficiency and air throughput while minimizing manufacturing and operational costs, as they often require complex designs and high production costs.
Innovation Solution
The axial blower design incorporates sockets in the rotor hub within the diverging section for mounting rotor blades at multiple angles, allowing for adjustable positioning and reduced turbulence, with separate moulded metal parts for the rotor hub and blades, and mounting flanges for easy integration into tubing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotor blades are mounted in fixed positions on the rotor hub, then manufacturing is simplified, but adaptability and optimization of blower performance are reduced
Solution Approach 1:
The rotor blades are designed to be rotatable about an axis perpendicular to the rotor hub surface, allowing dynamic adjustment of blade angles. This enables the blower performance to be optimized for different operating conditions while maintaining a relatively simple fixed structure for mounting, thus achieving adaptability without excessive complexity
Solution Approach 2:
The blade angle parameter can be changed by rotating the rotor blades to different angular positions about their mounting axis. This allows the same physical rotor hub structure to achieve different performance characteristics by simply changing the angular parameter of the blades, enhancing adaptability without requiring multiple complex hub designs
2Adaptability or versatility
If complex rotor hub designs with multiple mounting options are used, then adaptability is improved, but manufacturing costs and device complexity increase
Solution Approach 1:
The rotor hub is designed with universal sockets that can accommodate rotor blades at multiple angular positions (e.g., 0°, 45°, 90°, 135°). This multi-functional socket design allows a single, relatively simple hub structure to provide multiple mounting configurations, achieving mounting flexibility without requiring multiple specialized hub designs or increasing manufacturing complexity
Solution Approach 2:
The rotor hub is segmented into a body portion and a hub cap portion that together form the socket structure. This segmentation allows for simplified manufacturing of each part while providing the complete multi-angle mounting capability when assembled, reducing overall manufacturing cost while maintaining adaptability
3Productivity
If fixed blade angles are used, then device complexity is reduced, but efficiency and air throughput are limited
Solution Approach 1:
The rotor blades are designed to be rotatable about an axis perpendicular to the rotor hub surface, allowing dynamic adjustment of blade angles. This enables the blower performance to be optimized for different operating conditions while maintaining a relatively simple fixed structure for mounting, thus achieving adaptability without excessive complexity
Solution Approach 2:
The blade angle parameter can be changed by rotating the rotor blades to different angular positions about their mounting axis. This allows the same physical rotor hub structure to achieve different performance characteristics by simply changing the angular parameter of the blades, enhancing adaptability without requiring multiple complex hub designs
