Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable fans with low power consumption have poor air blowing and cooling effects due to low wind strength, and existing booster fan structures exacerbate noise and turbulence, affecting customer experience and hindering product popularity.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a traditional booster fan structure is applied to increase wind speed, then the cooling effect is improved, but the noise level increases due to turbulent air flow
Solution Approach 1:
The patent introduces a flow guide member as an intermediary component between the booster fan and the air outlet. This flow guide member redirects and smooths the turbulent air flow generated by the booster fan, reducing noise while maintaining the high wind speed effect. The flow guide acts as a mediator that converts harmful turbulent flow into useful directed flow.
2Power
If the fan size is increased to improve air blowing effect, then the wind strength increases, but the portability and convenience are reduced
Solution Approach 1:
The patent divides the fan system into two functional segments: a main fan for basic air movement and a separate booster fan module for enhanced wind speed. This segmentation allows the main fan to remain compact for portability while the booster fan provides concentrated high-velocity airflow when needed, achieving both small size and strong air blowing effect.
Solution Approach 2:
The patent adds a dimensional element by introducing a vertical booster fan structure that stacks upward from the main fan. This vertical arrangement increases air blowing power in the vertical dimension without significantly increasing the horizontal footprint, maintaining portability while enhancing cooling capability.
3Volume of moving object
If low power electric devices are used to maintain small size, then portability is improved, but the wind strength and cooling effect are reduced
Solution Approach 1:
The patent merges two fan systems into a unified module: the main fan and the booster fan are integrated into a single compact assembly. This merging allows both low-power (for portability) and high-power (for wind strength) characteristics to coexist, as the booster fan provides concentrated airflow while the overall device remains small and portable.
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 module significantly increases wind speed and air supply distance while achieving silence and noise reduction by optimizing air flow through a coordinated system of fan blades, flow guide, and rectifying hood.
Implementation Method 1
an air-driving fan blade group is arranged in the air duct; after driving air at the air inlet to flow into the air duct, the air-driving fan blade group blows the air outwards from the air outlet
Implementation Method 2
a boosting mechanism is arranged at the air outlet; the boosting mechanism boosts the air flow output by the air-driving fan blade group
Implementation Method 3
the flow guide member guides the air flow output from the boosting mechanism, so that the air flow is blown out in a direction parallel to an axial direction
Implementation Method 4
the rectifying and boosting hood outwards blows the air flow output by the flow guide member after performing boosting and turbulence removal on the air flow

AI summary
A high-speed booster fan module is provided, including an air duct, and an air inlet and an air outlet which are communicated to the air duct, wherein an air-driving fan blade group is arranged in the air duct; after driving air at the air inlet to flow into the air duct, the air-driving fan blade group blows the air outwards from the air outlet; a boosting mechanism is arranged at the air outlet; a flow guide member is arranged on one side of the boosting mechanism away from the air-driving fan blade group; and a rectifying and boosting hood is arranged on one side of the flow guide member away from the boosting mechanism. In the present disclosure, the air flow achieves boosting and speeding up under cooperation between the air-driving fan blade group and the boosting mechanism; the air flow is collectively gathered by guidance of the flow guide member, thereby effectively improving the utilization rate of the air flow; and finally, the air flow is blown outwards after being secondarily boosted through the rectifying and boosting hood and subjected to turbulence removal, so that a wind speed and an air supply distance are greatly increased, an effect of silence and noise reduction is achieved.
