Neck Fan Air Outlet Layout for Comfortable Portable Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small-sized fans are not optimally portable and the airflow generated is not comfortable for users.
Innovation Solution
A neck fan design that includes a main unit with soft connection portions and fan bodies at each end, featuring a partitioned cavity with baffles to direct airflow gently through side outlets, allowing hands-free operation and adjustable airflow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small-sized fans are used, then portability is improved, but the airflow generated is not comfortable for users
Solution Approach 1:
The fan body is divided into multiple air outlet channels (first air outlet channel and second air outlet channel) with different orientations. The first channel directs airflow horizontally while the second channel directs airflow obliquely downward, allowing the compact fan to provide comfortable multi-directional cooling without increasing size.
Solution Approach 2:
The patent introduces vertical airflow component through the obliquely downward directed second air outlet channel. This adds a vertical dimension to the airflow pattern, enabling the compact fan to deliver comfortable cooling that mimics natural breeze patterns without requiring larger fan blades.
2Ease of manufacture
If traditional fan designs are used, then manufacturing is simple, but airflow direction cannot be adjusted
Solution Approach 1:
The air outlet is segmented into multiple independent channels (first and second air outlet channels) with different orientations. Each channel can be independently designed into the housing structure, providing adjustable multi-directional airflow while maintaining a simple integrated manufacturing process without requiring moving parts or complex adjustment mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a comfortable and portable cooling solution with adjustable airflow direction, enhancing user comfort and versatility in various application scenarios.
Implementation Method 1
the wind generated by rotation of the fan is capable of flowing to reach the second baffle and subsequently being sent out of the neck fan through the side air outlet
