Wiper Blade Adapter System with Intermediate Coupler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade adapter systems are limited in their ability to accommodate wiper arms of different sizes, as they typically require jointed connections that are not adaptable to various dimensions, leading to compatibility issues and inefficient mounting processes.
Innovation Solution
A wiper blade adapter system featuring a joint-free wiper blade with an intermediate adapter that encloses the wiper blade adapter in multiple directions, incorporating side walls with elevations and a center piece formed by connecting struts, allowing for a U-shaped design that can be easily adapted to different wiper arm adapter sizes through adjustable fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a jointed connection is used in the wiper blade adapter system, then the connection can be articulated and adaptable, but the structure becomes more complex and the mounting process becomes less efficient
Solution Approach 1:
The patent introduces an intermediate adapter as a mediator component that couples the wiper blade adapter to the wiper arm adapter. This intermediate adapter serves as a bridge that enables compatibility between different sizes without requiring complex jointed connections. The intermediate adapter has a first coupling element for the wiper blade adapter and a second coupling element for the wiper arm adapter, thereby resolving the contradiction by providing adaptability through a simple intermediary structure rather than through articulated joints.
2Reliability
If the intermediate adapter encloses the wiper blade adapter in three directions, then the coupling is more secure and stable, but the weight of the adapter increases
Solution Approach 1:
The patent applies local quality by providing enclosures in only three directions (front, rear, and one side) rather than fully enclosing the wiper blade adapter in all directions. The open design on the opposite side reduces material usage and weight while maintaining sufficient coupling stability through the strategic placement of coupling elements and the U-shaped configuration. This selective enclosure provides the necessary reliability without the penalty of excessive weight.
3Reliability
If the wiper blade adapter is designed for a fixed connection to the wiper blade, then the connection is secure, but the mounting process becomes more time-consuming and less efficient
Solution Approach 1:
The patent segments the mounting system into separate, modular components: the wiper blade adapter with its fixed connection to the wiper blade, and the intermediate adapter with coupling elements for both the wiper blade adapter and the wiper arm adapter. This segmentation allows for pre-assembly of the wiper blade to the adapter, ensuring a secure fixed connection, while the modular intermediate adapter enables quick attachment and detachment, thereby reducing mounting time without compromising connection security.
