Angled Cleaning Tool for Vehicle Weather Seal Crevice Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning vehicle weather sealing strips are inadequate in accessing and removing sand and grit from the inner facing surface between the window and door panel, leading to potential window scratching, and require frequent washing or manual cloth cleaning which is inefficient and incomplete.
Innovation Solution
A flat elongate tool with a brush end and handle end, offset at obtuse angles and featuring a tapered, rounded tip, allowing access to crevices between the window and door panel, enabling effective removal of debris with a simple and affordable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cloth is used to wipe the weather sealing strip, then some sand and debris can be removed from the outer surface, but the inner facing surface in the crevices between the window and door panel remains inaccessible and contaminated
Solution Approach 1:
The cleaning tool is segmented into two distinct functional ends: a first end with brush material for cleaning the outer surface of the sealing strip, and a second end with a rounded tip for accessing and cleaning the inner facing surface in crevices. This segmentation allows each end to specialize in cleaning different areas, ensuring complete coverage of both accessible and inaccessible surfaces.
Solution Approach 2:
The tool transitions from a single-dimension approach (cloth wiping only the outer surface) to a two-dimension approach by adding a second functional end that accesses the inner crevice dimension. The rounded tip on the second end enables penetration into the crevice space between the window and door panel, cleaning areas that were previously inaccessible from the outer surface alone.
2Reliability
If frequent vehicle washing is performed to remove sand and grit from the weather sealing strip, then window scratching can be prevented, but time and resource consumption increase significantly
Solution Approach 1:
The tool enables preliminary cleaning action by allowing users to quickly remove sand and grit from the weather sealing strip immediately after beach visits or dusty trips, before the debris can scratch the window. This immediate intervention prevents the need for frequent full vehicle washes, as the critical window-protection function is achieved through targeted, quick cleaning sessions.
Solution Approach 2:
The dual-ended design enables the user to perform complete cleaning of both outer and inner surfaces independently without requiring professional detailing services or frequent car washes. The tool empowers the vehicle owner to maintain window protection through simple, self-administered cleaning of the sealing strip.
3Ease of manufacture
If a simple cloth-based cleaning method is used, then the device complexity and manufacturing cost remain low, but the ability to access and clean inner crevice areas is insufficient
Solution Approach 1:
The tool divides functionality into two simple segments on a single rod: a first end with brush material for outer surface cleaning and a second end with a rounded tip for crevice access. This segmentation adds crevice cleaning capability without requiring complex mechanisms, motors, or multiple separate tools, maintaining ease of manufacture while dramatically improving operational capability.
Solution Approach 2:
The rounded tip on the second end acts as an intermediary element that bridges the gap between the user and the inaccessible crevice area. This simple geometric feature enables the tool to penetrate and clean the narrow space between the window and door panel without requiring complex mechanical systems.
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
The tool allows for quick and thorough cleaning of the weather sealing strip, preventing window scratching by reaching inaccessible areas, is easy to use and maintain, and is cost-effective for mass production.
Implementation Method 1
A brush material covers both sides of the first end with the exception of the rounded tip
Implementation Method 2
The sand and other debris causes scratching of the glass of the window

AI summary
A cleaning tool for cleaning the weather sealing strip at the windows of a vehicle has a flat elongate strip that has a brush end and a handle end joined by a medial section, the medial section being offset relative to the brush end by a first obtuse angle and being offset relative to the handle end by a second obtuse angle. The brush end as a twist offset relative to the handle end, the twist being right-handed for right-handed users. The brush end is tapered and has a rounded tip and has a brush material covering this end except at the rounded tip. A handle encompasses the handle end.
