Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tools are used for locking fan blades to the ceiling fan main body, then the assembly is secure and reliable, but the assembly process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, bolts, and tools) with an elastic buckle mechanism. The elastic buckles engage with corresponding slots and holes to secure fan blades to the blade frame, eliminating the need for tools during assembly while maintaining secure attachment through elastic retention force.
Solution Approach 2:
The elastic buckles are designed to be self-installing components that automatically secure the fan blades when inserted into the blade frame. The elastic nature of the buckles allows them to self-latch into position without requiring external tools or complex fastening procedures, enabling tool-free assembly.
2Ease of manufacture
If ceiling fan assembly is performed at height, then the fan can be installed in the correct position, but the operation becomes difficult and more time-consuming
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, bolts, and tools) with an elastic buckle mechanism. The elastic buckles engage with corresponding slots and holes to secure fan blades to the blade frame, eliminating the need for tools during assembly while maintaining secure attachment through elastic retention force.
Solution Approach 2:
The ceiling fan is divided into separate modular components: the main body, the blade frame, and individual fan blades with pre-attached elastic buckles. This segmentation allows the main body to be installed first, followed by simple attachment of the blade frame and blades, making the installation process more manageable at height.
3Stability of the object's composition
If traditional blade assembly methods are used, then the connection is stable, but the assembly process requires tools and multiple steps
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, bolts, and tools) with an elastic buckle mechanism. The elastic buckles engage with corresponding slots and holes to secure fan blades to the blade frame, eliminating the need for tools during assembly while maintaining secure attachment through elastic retention force.
Solution Approach 2:
The elastic buckles are designed to be self-installing components that automatically secure the fan blades when inserted into the blade frame. The elastic nature of the buckles allows them to self-latch into position without requiring external tools or complex fastening procedures, enabling tool-free assembly.

Function Achieved in This Case
Enables quick and tool-free assembly of fan blades, ensuring stable positioning without the need for tools, facilitating easier installation.
Implementation Method 1
a first elastic buckle (222) arranged on a bottom side of the assembly portion (22) and corresponding to the buckle hole (115)... the first elastic buckle (222) is buckled with the buckle hole (115)... the plurality of tenon assemblies (3) press against the first elastic buckles (222) of the plurality of fan blades (2), respectively
Implementation Method 2
A second elastic buckle (31) is arranged on one side of each of the plurality of tenon assemblies (3)... the second elastic buckle (31) of each of the plurality of tenon assemblies (3) is engaged with a lower edge of one side of a corresponding one of the insertion holes (114)... so as to prevent the tenon assemblies to be ejected upward
