Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized air-conditioning air outlets in vehicles lead to uneven temperature distribution, causing discomfort as cold air directly blows on passengers, particularly affecting joints.
Innovation Solution
An air-conditioning air outlet structure featuring a shell with pinhole-type outlets distributed on a panel, an air duct, wind speed accelerators, and an air duct partition plate, which are strategically positioned and designed to distribute air uniformly across a large area, guiding wind direction and controlling air volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized air outlets are used, then the air outlet structure is simple, but the temperature distribution becomes uneven and causes discomfort
Solution Approach 1:
The patent divides the air outlet into multiple pinhole-type outlets distributed across the panel surface. Instead of using a single centralized outlet, the air outlet function is segmented into numerous small holes (each with diameter of 1-5mm) arranged in a grid pattern, allowing air to be discharged at multiple locations simultaneously. This segmentation enables uniform temperature distribution while maintaining structural simplicity.
Solution Approach 2:
The patent applies local quality by varying the distribution density of pinhole outlets across different regions of the panel. The number of pinholes per unit area is adjusted based on local requirements: higher density in regions needing more cooling and lower density in other areas. This localized optimization achieves uniform temperature distribution without requiring complex centralized control systems.
2Area of stationary object
If small air outlets are used, then the air outlet structure is compact, but the air discharge range is limited
Solution Approach 1:
The patent transitions from a single-point air outlet to a surface-distributed array of pinholes. By arranging multiple small outlets across the two-dimensional panel surface, the system achieves wide air discharge coverage without increasing the overall footprint of the air conditioning unit. The pinholes are distributed across the entire panel area, enabling cold air to reach multiple zones simultaneously.
Solution Approach 2:
The patent integrates the air outlet function within the interior trim panel structure itself. The pinhole-type outlets are formed directly in the panel, nesting the air discharge function within the existing decorative trim component. This eliminates the need for separate air outlet housings while achieving compact design and wide discharge range.
3Adaptability or versatility
If pinhole-type outlets are distributed densely, then the air discharge range increases, but the manufacturing precision requirement increases
Solution Approach 1:
The patent specifies precise parameters for the pinhole outlets: diameter of 1-5mm and controlled distribution density (number of pinholes per unit area). By standardizing these parameters, the system achieves wide air discharge range while maintaining manufacturability. The uniform size and spacing parameters simplify the manufacturing process compared to varying outlet sizes and positions.

AI summary
The present invention provides an air-conditioning air outlet structure. The structure includes: a shell, the shell includes a panel and a side plate, the panel serves as an interior trim part, a plurality of pinhole type air outlets are distributed on the panel of the shell, and the pinhole type air outlets are relatively sparsely distributed at positions near the air-conditioning air duct and are relatively densely distributed at positions far from the air-conditioning air duct. The structure improves the problem of uneven temperature in a vehicle caused by the centralized arrangement of air-conditioning air outlets and the smaller sizes of the air outlets, so that the air-conditioning air outlets discharge air within a large range, in this way, the temperature in the vehicle is more uniform, and the human body feels more comfortable.
