Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adapters are used to accommodate different wiper driving arm designs, then the adaptability of the windshield wiper increases, but the device complexity and overall cost increase
Solution Approach 1:
The base is designed with a universal structure that can accommodate multiple types of wiper driving arms through a standardized interface. The combining hole and positioning structures allow different driving arm designs to connect to the same base without requiring multiple adapters, making the base multi-functional and compatible with various wiper blade types.
Solution Approach 2:
The patent merges the functions of multiple adapters into a single base design. By integrating universal positioning features (combining holes, positioning grooves) directly into the base structure, the need for separate adapter components is eliminated, simplifying the overall system while maintaining compatibility with different driving arm designs.
2Adaptability or versatility
If multiple adapters are used to accommodate different wiper driving arm designs, then the adaptability of the windshield wiper increases, but the manufacturing cost increases
Solution Approach 1:
The base is designed as a universal component that can work with multiple types of wiper driving arms through standardized interface features. This eliminates the need to manufacture multiple different adapter components, reducing manufacturing complexity and cost while maintaining broad compatibility across different wiper blade designs.
Solution Approach 2:
The patent extracts the adaptability function from separate adapter components and integrates it directly into the base structure. By incorporating positioning holes, grooves, and interface features directly in the base, the adaptability function is built-in, eliminating the need for additional adapter parts and reducing overall manufacturing costs.
3Adaptability or versatility
If multiple adapters are required for different wiper driving arms, then the adaptability increases, but the assembly process becomes more troublesome
Solution Approach 1:
The patent combines the adaptability features directly into the base structure, merging the functions of multiple adapters into one component. The base includes integrated positioning holes, grooves, and interface features that allow different wiper driving arms to be assembled directly without requiring separate adapter components, greatly simplifying the assembly process.
Solution Approach 2:
The base is designed as a universal mounting platform with standardized interface features that accommodate multiple types of wiper driving arms. This universal design allows users to assemble different wiper blades directly to the same base using a consistent procedure, eliminating the need to learn different assembly methods for different adapter types.

AI summary
This disclosure relates to an assembly structure (1) of a windshield wiper. A base (10) includes a seat (11) and a slot (12). A seat (11) includes an accommodating space (110), a plurality of limiting grooves (111), a fastening portion (112) and an elastic pressing piece (113). The slot (12) is disposed on a bottom side of the seat (11) for inserting a wiper blade (30). The linking set (20) includes a seat plate (21). The seat plate (21) includes a plurality of guiding blocks (22), a latch (23) and an elastic arm (24). The latch (23) is obliquely inserted into the seat (11) and rotate to make the seat plate (21) place in the accommodating space (110). The linking set (20) is pushed by an external force to make the elastic arm (24) move toward the fastening portion (112). The elastic arm (24) is engaged with the fastening portion (112) and abuts against the elastic pressing piece (113). The guiding blocks (22) slide into the limiting grooves (111) correspondingly.
