Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air dispersing devices in air conditioners with single-layer plates have unsatisfactory air dispersing effects in breezeless mode, leading to inadequate comfort levels.
Innovation Solution
An air dispersing device with a dual-layer frame system, comprising a first air dispersing plate with micro-holes and a second air dispersing plate with ventilation openings, along with a movable impeller that rotates to disperse airflows, increasing the airflow range and reducing speed, thereby enhancing the air dispersing effect in breezeless mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer air dispersing plate with micro-holes is used, then the structure is simple, but the air dispersing effect in breezeless mode is unsatisfactory
Solution Approach 1:
The air dispersing plate is divided into two separate layers: a first air dispersing plate with micro-holes for initial airflow interception and speed reduction, and a second air dispersing plate with ventilation openings for further dispersal. This segmentation allows each layer to perform its specific function optimally, significantly improving the air dispersing effect in breezeless mode while maintaining reasonable structural complexity
Solution Approach 2:
The invention transitions from a single-layer two-dimensional structure to a multi-layer three-dimensional structure by stacking two air dispersing plates at different positions. The first plate is positioned closer to the airflow source while the second plate is positioned further away, creating a spatial dimension that enhances airflow dispersal effectiveness through sequential interception and dispersal stages
2Device complexity
If a single-layer air dispersing plate is used, then the device complexity is low, but the comfort level is unsatisfactory
Solution Approach 1:
By segmenting the air dispersing function into two separate plates with different hole patterns and positions, the system achieves superior airflow control and comfort in breezeless mode. The first plate handles initial speed reduction while the second plate provides fine dispersal, creating a more comfortable user experience without excessive complexity
Solution Approach 2:
Each air dispersing plate is designed with specific local characteristics: the first plate has micro-holes optimized for initial airflow interception and speed reduction, while the second plate has ventilation openings configured for enhanced dispersal. This local optimization of each component's quality contributes to overall comfort improvement
