Bladeless Fan Air Supply Frames for Low-Noise Multi-Mode Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bladeless fans have limitations in air supply modes, leading to increased noise, lower wind speed, and poor user experience due to integrated air supply parts and threaded connections prone to damage and air leakage.
Innovation Solution
The design incorporates multiple rotatable air supply frames with independent rotation capabilities, enhanced air passage communication, and a rotatable connection mechanism between the air supply frames and connection seats, along with a sealing system to prevent air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the air supply part is designed as an integrated ring structure, then the structural integrity is improved, but the air passage transmission distance becomes longer resulting in higher noise and lower wind speed
Solution Approach 1:
The patent divides the air supply structure into multiple independent air supply frames (first air supply frame, second air supply frame, etc.) that are separately connected to the connection seat, rather than using a single integrated ring structure. Each frame has its own air passage, which shortens the transmission distance and reduces noise while maintaining structural integrity through modular design.
2Stability of the object's composition
If the air supply part is designed as an integrated ring structure, then the structural integrity is improved, but the wind speed becomes lower due to longer air passage transmission distance
Solution Approach 1:
The patent divides the air supply structure into multiple independent air supply frames (first air supply frame, second air supply frame, etc.) that are separately connected to the connection seat, rather than using a single integrated ring structure. Each frame has its own air passage, which shortens the transmission distance and reduces noise while maintaining structural integrity through modular design.
3Strength
If threaded connection is used between base and post, then the connection strength is improved, but additional sealing components cannot be placed resulting in air leakage
Solution Approach 1:
The patent separates the connection function into two independent mechanisms: a threaded connection for mechanical strength and a sealing component (sealing ring) for air tightness. The sealing component is installed in a sealing groove of the connection seat and works independently from the threaded connection, allowing both strong connection and reliable sealing simultaneously.
4Reliability
If plug-in electrical connection is used in threaded connection, then the electrical connection is achieved, but the threaded rotation is damaged due to friction between contact surfaces
Solution Approach 1:
The patent separates the electrical connection function from the mechanical connection function. The electrical connection is achieved through separate conductive pieces that are connected via a plug-in structure independent of the threaded connection. This allows the threaded rotation to proceed without friction from electrical contacts, while the electrical connection is established through the separate conductive path.
5Adaptability or versatility
If multiple air supply frames are used with independent rotation, then the air supply modes are improved, but the device complexity increases
Solution Approach 1:
The patent divides the air supply structure into multiple independent air supply frames (first air supply frame, second air supply frame, etc.) that are separately connected to the connection seat, rather than using a single integrated ring structure. Each frame has its own air passage, which shortens the transmission distance and reduces noise while maintaining structural integrity through modular design.
Solution Approach 2:
The connection seat is designed with universal connection capabilities that can accommodate multiple air supply frames with independent rotation. The connection mechanism and drive mechanism are designed to handle multiple frames simultaneously, allowing the system to provide diverse air supply modes without proportionally increasing complexity.
