Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bladeless fan uses a fixed base structure, then the structure is simple and easy to manufacture, but it cannot adapt to uneven placement surfaces and is easy to be tipped
Solution Approach 1:
The base structure transitions from a fixed, static design to a dynamic, adjustable one. The telescopic brackets can extend and retract, allowing the base to adapt its height and configuration to match uneven surfaces. This dynamic adjustment capability enables the fan to maintain stability on various surface conditions while keeping the overall structural design relatively simple.
Solution Approach 2:
The base is divided into multiple independent telescopic brackets instead of a single rigid structure. Each bracket can be adjusted independently to accommodate different height requirements, allowing the base to conform to uneven surfaces. This segmentation enables adaptability without requiring a completely complex restructured base design.
2Adaptability or versatility
If telescopic brackets are added to the base, then adaptability to uneven surfaces is improved, but the base structure becomes more complex
Solution Approach 1:
The telescopic brackets incorporate movable components that can extend and retract as needed. This dynamic mechanism allows the brackets to adjust their length to match uneven surfaces, providing adaptability while maintaining a relatively compact and simple structure when not in use.
Solution Approach 2:
The length parameter of the telescopic brackets can be changed to adapt to different surface conditions. By adjusting the extension length of each bracket, the base can compensate for surface irregularities. This parameter adjustment capability provides adaptability without requiring a fundamentally complex structural redesign.
3Ease of operation
If the support slides freely in the through channel, then adjustment is easy, but the support cannot remain stable in position
Solution Approach 1:
The rubber layer provides friction-based feedback resistance that opposes the sliding motion of the support. When the support is adjusted to a desired position, the friction from the rubber layer prevents it from sliding further, providing stable positioning. This feedback mechanism enables easy adjustment while maintaining position stability without complex locking systems.
Solution Approach 2:
The rubber layer is pre-installed on the inner wall of the through channel to provide frictional resistance before the support needs to be positioned. This beforehand cushioning effect prevents the support from sliding freely once adjusted, ensuring stable positioning while maintaining ease of adjustment through the friction-based resistance.

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 fan achieves stability on uneven surfaces through adjustable telescopic brackets and ensures reliable operation with temperature control and Bluetooth connectivity for enhanced user experience.
Implementation Method 1
the inner wall of the through channel is provided with a rubber layer. The telescopic bracket includes a support and a handgrip connected with the support, and the base is provided with a guide groove. The guide groove is arranged along the height direction of the base, the handgrip is inserted into the guide groove and can be moved relative to the guide groove, the support is installed in the through channel, is in contact with the rubber layer, and can relatively slide along the through channel and the through hole
