Solution Overview
Problem
Conventional air diffusers fail to effectively reduce temperature non-uniformity, such as hot spots, cold spots, and drafts, in rooms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional air diffusers are used, then air distribution is provided, but temperature non-uniformity (hot spots, cold spots, drafts) occurs
Solution Approach 1:
The patent employs a substantially hemispherical dome shape for the diffuser body, which naturally promotes uniform air distribution patterns. The curved surface geometry creates more consistent airflow trajectories compared to conventional flat or angular designs, reducing temperature non-uniformity and eliminating hot and cold spots while maintaining manufacturing feasibility through standard forming processes
2Productivity
If a high percentage of aperture area is used, then air distribution effectiveness is improved, but structural integrity may be compromised
Solution Approach 1:
The diffuser incorporates a porous baffle element with controlled aperture distribution, where the total aperture area constitutes a high percentage of the diffuser face area. The porous structure provides sufficient structural integrity while enabling effective air distribution, as the distributed pore network maintains structural strength even with high overall porosity
Solution Approach 2:
The patent varies the aperture size and distribution locally across the diffuser surface, with different regions having optimized aperture characteristics. This local quality variation ensures that structural strength is maintained in critical areas while maximizing air distribution effectiveness in other regions, achieving both high productivity and structural integrity
