Solution Overview

Problem

Aftermarket wiper blades face challenges with lateral stability and wrapping issues due to varying wiper arm designs, necessitating universal connectors that can accommodate different types of wiper arms while ensuring secure attachment and effective windshield contact.

Innovation Solution

A wiper blade connector assembly featuring a design with side walls, a connector channel, rivet cutout, and a hook end stop, along with a pivotable cover and adapter, to securely connect wiper blades to wiper arms of varying types, ensuring stability and uniform contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If beam blades are used to achieve a lower profile and more uniform distribution, then the wiper blade can provide better original equipment performance, but the blade lacks lateral stability and experiences wrapping problems when curvature is too sharp for the windshield

Engineering Contradiction:
Improveblade profile and curvatureVSAvoidlateral stability
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The patent combines beam-like characteristics with traditional bracket structures to create a hybrid wiper blade. The connector assembly integrates both beam elements (providing uniform distribution and low profile) and bracket elements (providing lateral stability through side walls and structural support), resolving the contradiction between blade shape performance and lateral stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector assembly is designed with multiple functional components (connector channel for different arm types, rivet cutout for secure attachment, hook end stop for various hook styles) that enable it to serve multiple functions and accommodate different wiper arm designs while maintaining both beam blade performance and lateral stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If traditional bracketed wiper blades are used to achieve lateral stability, then the blade maintains structural rigidity, but the blade does not provide a lower profile and uniform distribution

Engineering Contradiction:
Improvelateral stabilityVSAvoidblade profile and contact uniformity
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The hybrid connector assembly merges the structural advantages of traditional brackets (lateral stability from side walls) with the aerodynamic and contact advantages of beam blades (lower profile and uniform distribution), allowing the blade to achieve both lateral stability and improved shape characteristics simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If universal connectors are designed to accommodate various wiper arm types, then the connector can be used across different vehicles, but the connector design becomes more complex

Engineering Contradiction:
Improvecompatibility with different wiper arm typesVSAvoidconnector structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector assembly is designed as a universal multi-functional component with a connector channel that accommodates different wiper arm types, a rivet cutout for secure attachment, and a hook end stop for various hook styles. This universal design achieves high adaptability while managing complexity through integrated, standardized features.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connector assembly is divided into distinct functional segments (connector channel, rivet cutout, hook end stop, side walls) that can independently accommodate different wiper arm types. This segmentation allows each component to be optimized for its specific function while contributing to overall versatility without excessive complexity.

Inventive Principle:
Principle #1Segmentation
