Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the windshield wiper adapter uses a convex hull and notch structure for fastening, then the fastening strength is improved, but the assembly requires a specific narrow angle range which reduces ease of operation
Solution Approach 1:
The patent changes the physical state of the fastening components from rigid to flexible. The flexible buckling body can deform during assembly to accommodate various insertion angles, then restores its shape to provide secure fastening. This parameter change resolves the contradiction by allowing both easy assembly (through deformation) and strong fastening (through restored rigidity).
Solution Approach 2:
The patent introduces dynamic characteristics to the fastening system through the flexible buckling body that can dynamically adjust its shape during assembly and detachment. The body transitions from a deformed state during insertion to a restored state during fastening, enabling operation at arbitrary angles while maintaining secure connection.
2Strength
If the windshield wiper adapter uses hardness materials for fastening components, then the fastening strength is improved, but the friction increases causing wear and reducing reliability over time
Solution Approach 1:
The patent changes the material property parameter from hard to flexible for the buckling body. This flexible material provides sufficient fastening strength through elastic deformation and restoration, while simultaneously reducing friction during assembly and detachment, thereby preventing wear and maintaining long-term reliability.
Solution Approach 2:
The flexible buckling body acts as a cushioning element during assembly, absorbing impact and reducing friction through its deformable nature. This beforehand cushioning prevents direct hard contact between fastening components, reducing wear before it occurs and ensuring long-term installation stability.
3Strength
If the windshield wiper adapter uses a convex hull structure, then the fastening strength is improved, but the detachment process becomes complicated requiring specific manipulation
Solution Approach 1:
The flexible buckling body enables simple detachment by allowing the user to manually deform the body, which releases the fastening engagement. The dynamic flexibility of the body allows it to be easily deformed for detachment, then naturally restores its shape for secure fastening, simplifying the detachment process while maintaining strong fastening.
Solution Approach 2:
The flexible buckling body provides self-service functionality where manual deformation automatically triggers the release mechanism. When deformed, the body naturally disengages from the through hole, and upon release, automatically restores its shape for fastening, eliminating the need for complex manipulation or additional tools.

Implementation Method 1
the flexible buckling device is engaged with the leading side of the through hole to firstly perform a deformation process toward a direction away from the leading side of the through hole, and then the flexible buckling device is lodged with the leading side of the through hole after restoring from the deformation process

AI summary
A windshield wiper adapter and windshield wiper assembly are disclosed. The windshield wiper adapter comprises a main body and a flexible buckling device. A front end of the main body has a notch that is downwardly recessed. The notch is used for snapping with a protrusion portion of a windshield wiper arm at an arbitrary angle. One end of the flexible buckling device is connected to a surface of the main body while another end is upwardly extended toward an upper side of the main body. The flexible buckling device is used for buckling a leaning side of a through hole of the windshield wiper arm. After the notch is coupled to the protrusion portion, the windshield wiper arm is rotated about a coupling portion therebetween, such that the flexible buckling device is propped by the leaning side of the through hole to firstly perform a deformation process.
