Integrated Brush Wiper Insert for Stubborn Dirt and Ice Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windscreen wipers struggle to effectively remove stubborn dirt, ice, and sleet, often requiring chemical cleaners that pose environmental burdens, and existing brush-enhanced wipers are complex, costly, and can scratch glass surfaces or detach from the wiper.
Innovation Solution
A windscreen wiping insert with integrated rows of brushes on both sides of the wiping blade, allowing efficient dirt removal without additional support elements, integrated into the blade for simplicity and durability, using materials like plastic, titanium, or rubber bristles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional brush-supporting elements are arranged on the windscreen wiping insert to enhance cleaning effect, then cleaning efficiency is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the brush row and wiping blade into a single integrated component called a 'wiping insert'. The brushes are arranged directly on the wiping blade surface, eliminating the need for separate brush holder elements. This merging approach maintains enhanced cleaning capability while significantly reducing structural complexity and manufacturing cost.
2Reliability
If a robust brush holder design is used to secure brushes, then brush stability is improved, but manufacturing complexity and production difficulty increase
Solution Approach 1:
The wiping insert integrates brushes directly into the wiping blade structure, allowing brushes to be secured through simple adhesive bonding or mechanical embedding in the blade material. This eliminates complex brush holder assemblies while maintaining brush stability during operation.
3Object-affected harmful factors
If conventional windscreen wipers are used without chemical cleaners, then environmental impact is reduced, but cleaning effectiveness on stubborn dirt decreases
Solution Approach 1:
The wiping insert segments the cleaning function into two distinct components: brushes for mechanical removal of stubborn dirt and ice, and the wiping blade for final surface cleaning. This segmentation enables effective mechanical cleaning without requiring chemical cleaners, reducing environmental impact while maintaining cleaning effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cleaning efficiency while maintaining visibility and reducing wear, extending the wiper's lifespan, and minimizing environmental impact by eliminating the need for chemical cleaners.
Implementation Method 1
a spring structure
Implementation Method 2
a row of brushes arranged along the length of the base member, wherein the at least one row of brushes is integrated directly into the wiping blade

AI summary
A replaceable windscreen wiping insert forming part of a wiper which is provided with a row of brushes for cleaning a vehicle's windscreens and headlights. The wiping insert includes an elongated base member having a connecting element for attaching it to a wiper adapter; at least one wiping blade extending from the base member along the length thereof and being deflected relative thereto during use; and at least one row of brushes arranged along the length of the base member. The at least one row of brushes is integrated directly into the wiping blade such that the row of brushes is arranged projecting from a first longitudinal side of the wiping blade or from a second longitudinal side opposite thereto. The disclosure also relates to a windscreen wiper including the wiping insert and to a method for retrofitting available wiping inserts with a row of brushes.
