Flexible Neck Fan Connection for Direct Vertical Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional neck fans fail to provide a direct and efficient cooling effect, failing to meet user expectations for faster and more personalized cooling in high-temperature environments.
Innovation Solution
A neck fan design featuring a flexible connection member that connects two fan portions, allowing air to be blown directly and centrally towards the user, with a straight-tube-shaped air guide chamber and neck supports to enhance air flow efficiency and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional neck fan design is used, then portability is achieved, but cooling effect is insufficient and air flow is not direct or centralized
Solution Approach 1:
The neck fan is divided into two separate fan portions (first fan portion and second fan portion) that are arranged opposite each other and connected through a flexible connection portion. This segmentation allows each fan portion to independently contribute to the cooling effect while maintaining portability, directly addressing the insufficient cooling effect of traditional single-structure neck fans.
Solution Approach 2:
The patent introduces a vertical air flow dimension by arranging the two fan portions oppositely and connecting them through a flexible connection portion, enabling air to be blown vertically towards the user. This dimensional change transforms the traditional horizontal or radial air flow pattern into a vertical directed flow, achieving more direct and centralized cooling.
2Productivity
If air is blown more directly and centrally towards user, then cooling effect is improved, but device structure becomes more complex
Solution Approach 1:
The flexible connection portion is made of a flexible material that can bend and adapt to different neck shapes, allowing the two fan portions to be positioned optimally for vertical air flow while maintaining comfort and portability. This flexible connection simplifies the overall structure compared to rigid mounting mechanisms while achieving the desired air blowing efficiency.
Solution Approach 2:
The flexible connection portion allows the fan portions to dynamically adjust their relative positions and orientations, enabling the air flow direction to be optimized for direct vertical blowing towards the user. This dynamic adaptability improves air blowing efficiency without requiring a complex fixed structure.

AI summary
A connection member of a neck fan configured to connect to a first fan portion and a second fan portion arranged opposite each other, the connection member includes a flexible connection portion. The flexible connection portion is provided with at least one installation hole. The at least one installation hole is configured to extend along an extending direction from a first connection end of the first fan portion to a second connection end of the second fan portion. The at least one installation hole is further configured to be sleeved and fixed onto the first connection end and the second connection end, so that the first fan portion and the second fan portion are connected through the flexible connection portion.
