Vehicle Side Window Wiping Assembly with Segmented Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window wiping assemblies for vehicles are inadequate in effectively removing moisture and debris from side windows, particularly when the window is raised and lowered, which can compromise visibility and safety during driving.
Innovation Solution
A window wiping assembly comprising a positioning element mountable to a vehicle door with a wiper blade extending between the lower edge of the window opening, where the wiper blade contacts the exterior window face to remove moisture and debris as the window moves, utilizing a resilient material and adjustable couplers for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wiper blade is used on side windows, then moisture and debris can be removed from the window, but the wiper blade cannot effectively clear the entire window surface when the window is raised and lowered
Solution Approach 1:
The wiper blade is divided into multiple segments or sections that can independently contact different portions of the window surface. This segmentation allows the wiper system to effectively clear the entire window area, including upper portions that would otherwise remain contaminated when the window is in raised or lowered positions.
Solution Approach 2:
The wiper blade is positioned and oriented to contact the window at an angle rather than purely horizontally. This angular positioning allows the wiper to reach and clear moisture and debris on the upper portions of the window that are not accessible to conventional horizontally-oriented wiper blades, thereby maintaining visibility across the entire window surface.
2Reliability
If the wiper blade is positioned to contact the window, then contaminants can be removed, but the positioning and attachment mechanism becomes complex
Solution Approach 1:
The positioning element serves multiple functions: it provides structural support for the wiper blade, enables angular positioning relative to the window, facilitates attachment to the vehicle door, and allows for adjustment of the wiper blade's contact point. By combining these functions into a single integrated component, the design achieves effective contaminant removal without proportionally increasing overall system complexity.
Solution Approach 2:
The wiper blade and positioning element are designed with adjustable and movable components that allow the system to adapt to different window positions and angles. This dynamic capability enables the wiper to maintain effective contact with the window surface whether the window is raised, lowered, or in intermediate positions, while the adjustment mechanisms remain relatively simple in construction.

AI summary
A window wiping assembly for removing moisture and debris from a side window of a vehicle includes a positioning element that is mountable to an exterior surface of a vehicle door having a window opening positioned therein. The positioning element extends substantially between opposed endpoints of a lower edge of the window opening. A wiper blade is engaged to and extends from an inner face of the positioning element so that an outer edge of the wiper blade contacts an exterior face of a window that is positioned in the window opening. The wiper blade extends substantially between opposed ends of the positioning element. The wiper blade removes moisture and debris from the exterior face of the window as the window is raised and lowered within the window opening.
