Solution Overview

Problem

Existing windshield wiper systems have suboptimal alignment of wiper blades, leading to inefficient cleaning of glass surfaces and airflow disturbances, which affects the stability and effectiveness of the wiper blades.

Innovation Solution

An adapter is designed with a specific configuration that includes a reception housing with a sleeve and an opening, allowing for a compact design that optimizes the support of the wiper blade on the glass surface, stabilizes its position, and reduces airflow disturbances by positioning the wiper blade closer to the glass surface and aligning it with the airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the wiper blade is pressed against the glass surface using conventional deflectors, then the cleaning effectiveness is improved, but the adapter size and complexity increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidadapter complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the receiving housing and reinforcement into a single integrated structural element. The reinforcement is formed as an integral part of the receiving housing, eliminating the need for separate components and simplifying the adapter structure while maintaining the pressing function against the glass surface

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The receiving housing serves multiple functions simultaneously: it receives and positions the wiper arm, provides structural reinforcement through its integrated design, and enables the pressing action against the glass surface. This multi-functionality reduces the need for additional specialized components

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

2Stability of the object's composition

If the receiving housing is positioned further from the wiper blade to improve stability, then the wiper blade stability is improved, but the adapter length increases

Engineering Contradiction:
Improvewiper blade stabilityVSAvoidadapter length
Core Design Contradiction:
Stability of the object's compositionVSLength of moving object

Solution Approach 1:

The patent positions the receiving housing in a lateral offset position relative to the wiper blade's longitudinal axis, rather than simply moving it further along the length. This dimensional change in positioning allows the housing to be closer to the blade while maintaining stability through the offset configuration and integrated reinforcement structure

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the wiper blade is aligned closer to the glass surface, then the cleaning efficiency is improved, but the airflow disturbances increase

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidairflow disturbances
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The integrated reinforcement structure is strategically positioned and shaped to provide localized structural support exactly where needed for optimal blade alignment. This localized reinforcement allows the blade to be positioned closer to the glass surface while the reinforcement geometry helps manage airflow patterns in the specific region, reducing disturbances

Inventive Principle:
Principle #3Local quality
