Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air circulators with flat grill structures fail to direct airflow to the center, resulting in insufficient airflow speed and reduced reach distance, which limits their ability to effectively agitate air and enhance cooling efficiency.
Innovation Solution
An air circulator with a blower unit featuring a grill structure that includes spiral airflow guide blades, where the inner end portions are convex and protrude more than the outer end portions, forming a three-dimensional shape, and a circular ring to concentrate airflow to the center, enhancing airflow speed and reach distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flat planar grill structure is used, then the device complexity is reduced, but the airflow speed and reach distance are insufficient
Solution Approach 1:
The grill structure transitions from a two-dimensional flat planar design to a three-dimensional configuration where airflow guide blades protrude outward to form a convex shape. This dimensional change allows the blades to effectively direct airflow toward the center while maintaining structural simplicity, thereby increasing airflow speed and reach distance without significantly complicating the device.
2Ease of manufacture
If a flat planar grill structure is used, then the manufacturing is simpler, but the airflow cannot be directed to the center resulting in insufficient reach distance
Solution Approach 1:
The airflow guide blades are designed with a convex curved shape that protrudes outward from the flat plane, forming a spherical or dome-like structure. This curvature naturally guides airflow along the curved surface toward the center, extending the reach distance of the airflow while maintaining ease of manufacture through simple molding or forming processes.
3Speed
If the grill is made three-dimensional with convex airflow guide blades, then the airflow speed is improved, but the device complexity increases
Solution Approach 1:
The airflow guide blades are integrated into a single unified grill structure rather than being separate components. The convex three-dimensional shape is formed as one piece, merging the blade structure with the grill body, which simplifies assembly and reduces overall device complexity while maintaining the airflow speed improvements.
4Device complexity
If a flat planar grill structure is used, then the structure is simpler, but air in the room cannot be agitated surely
Solution Approach 1:
The airflow guide blades are strategically positioned and shaped with varying convex heights across the grill surface. The blades are denser and more prominently convex in regions where airflow direction control is most needed, creating localized quality variations that enhance air agitation effectiveness while keeping the overall structure relatively simple.
