Universal Coupler for Beam Blade Wiper Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper assemblies are limited by fixed couplers that only work with specific wiper arm attachment members, restricting compatibility and requiring multiple replacement assemblies, which increases costs and reduces aftermarket options.
Innovation Solution
A universal coupler assembly for beam blade windshield wiper assemblies that includes a carrier, saddle, and coupler design capable of engaging various attachment members such as pinch-type, push-button-type, pin-type, and pin-and-bent-tab-type, allowing for interchangeable use across different wiper arm styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed coupler design is used for beam blade windshield wiper assemblies, then the coupling mechanism is simple and reliable, but compatibility with different wiper arm attachment members is limited
Solution Approach 1:
The coupler assembly is designed with a universal interface that can accommodate multiple types of wiper arm attachment members including pinch-type, push-button-type, pin-type, and pin-and-bent-tab-type attachments. The carrier, saddle, and coupler components work together to provide a single coupler design that performs multiple attachment functions, eliminating the need for different coupler designs for different attachment types.
2Adaptability or versatility
If multiple specialized windshield wiper assemblies are provided for different wiper arm styles, then compatibility is ensured, but costs and inventory requirements increase
Solution Approach 1:
By designing a single universal coupler assembly that can interface with multiple wiper arm attachment types, the patent eliminates the need for manufacturers to produce and stock multiple specialized wiper assemblies for different attachment styles. This reduces inventory requirements and allows end users to purchase a single type of replacement assembly that will fit various wiper arm configurations.
3Ease of operation
If a universal coupler design is implemented, then compatibility and options increase, but the coupler assembly structure becomes more complex
Solution Approach 1:
The coupler assembly is divided into distinct functional components including a carrier that mounts to the beam, a saddle that provides the attachment interface, and a coupler that engages with the wiper arm. This segmentation allows each component to be optimized for its specific function while working together to provide universal compatibility, managing complexity through modular design.

AI summary
A beam blade windshield wiper assembly having a universal coupler assembly including a carrier, a saddle that is removably received and retained by the carrier, and a coupler that is operatively mounted to the saddle. The carrier, saddle, and coupler cooperate to accommodate various sizes of “pinch-type” attachment members, “push-button-type” attachment members, as well as “side-pin-type” and “pin-and-bent-tab-type” attachment members that are used to connect the wiper arm and the windshield wiper assembly.
