Perforated Air Conditioner Blade for Comfortable Multi-Outlet Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling type air conditioners face challenges in efficiently discharging air through multiple outlets while maintaining high discharge efficiency and user comfort, as existing designs often result in direct air discharge that can be unpleasant for users.
Innovation Solution
The air conditioner features a blade with a unique pattern of holes and a rib structure that allows air to be discharged through multiple small holes when the blade is closed, reducing wind speed and improving user satisfaction by distributing air efficiently without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air is discharged through a single outlet, then the discharge efficiency is high, but the user comfort deteriorates due to direct air discharge
Solution Approach 1:
The single outlet is segmented into multiple small holes distributed across the blade surface. This segmentation allows the air discharge function to be distributed across multiple points, reducing the directness and intensity of air discharge at any single location, thereby improving user comfort while maintaining overall discharge efficiency.
Solution Approach 2:
The air discharge is transitioned from a single-point outlet to a distributed two-dimensional pattern of holes across the blade surface. This dimensional change allows air to be discharged across a broader area, reducing concentrated airflow and improving comfort while preserving total air volume discharge.
2Object-affected harmful factors
If multiple outlets are provided, then user comfort is improved by distributing air discharge, but the discharge efficiency deteriorates
Solution Approach 1:
Different regions of the blade are assigned different functions: the block area contains no holes to maintain structural integrity and discharge efficiency, while the non-block areas contain distributed holes for comfortable air discharge. This local differentiation optimizes both comfort and efficiency simultaneously.
3Object-affected harmful factors
If holes are formed throughout the entire blade area, then air discharge distribution is maximized, but the structural strength deteriorates
Solution Approach 1:
The blade area is segmented into a block area (without holes) and a non-block area (with holes). This segmentation preserves structural strength in the block area while enabling adequate air discharge distribution in the non-block area, balancing both requirements.
Solution Approach 2:
The blade exhibits local quality differentiation where the block area maintains high structural strength with no holes, while the non-block area provides sufficient air discharge distribution. This localized functional differentiation resolves the contradiction between strength and discharge distribution.
