Window cleaning tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window cleaning tools are inadequate for reaching and cleaning the corners of automobile rear windows without causing injury from sharp edges, and they do not allow for effective attachment of a non-scratch scouring pad for thorough residue removal before applying window tinting film.
Innovation Solution
A window cleaning tool with a rigid flat plate member and adjustable strap for secure hand attachment, featuring a hook and loop fastener for a non-scratch scouring pad, allowing for easy access to corners and preventing finger injury, with the pad shaped to match the tool's edge for even pressure and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a rectangular cleaning pad is used, then the cleaning tool can cover a large area, but it cannot reach the corners of the rear window effectively
Solution Approach 1:
The cleaning tool incorporates a nose with rounded contours and curved edges instead of sharp angles, allowing the tool to smoothly reach into and clean the corner regions of the rear window while maintaining adequate cleaning surface area
2Ease of operation
If the user reaches into the corners to clean them, then corner cleaning is possible, but the user's fingers are jammed into sharp structures causing injury
Solution Approach 1:
The cleaning tool acts as an intermediary between the user's hand and the window corner, with the strap and plate member providing a protective barrier that allows the user to apply cleaning force to corners without direct finger contact with sharp window frame structures
Solution Approach 2:
The rounded nose and curved edges of the cleaning tool protect the user's fingers by eliminating sharp corners that could cause injury, while still allowing effective application of cleaning force to the window surface
3Reliability
If a non-scratch scouring pad is attached to the cleaning tool, then thorough residue removal is achieved, but the attachment mechanism must be secure yet releasable
Solution Approach 1:
The hook and loop fastener system allows for adjustable attachment strength through the interaction of hook and loop densities and configurations, providing both secure attachment for effective cleaning and easy releasability when needed
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 effectively cleans the interior surfaces of automobile rear windows, including corners, without finger injury, ensuring proper residue removal for window tinting film application by providing secure, adjustable, and safe access with a non-scratch pad.
Implementation Method 1
Hook components of a hook and loop fastener on the bottom of the plate member allow for releasable attachment of a non-scratch scouring pad thereto
Implementation Method 2
A strap passes through elongate slot openings in the plate member to allow the plate member to be secured to a user's hand

AI summary
A window cleaning tool for removing dirt, dust, residue and other debris from the surface of a window includes a rigid plate member having a flat top surface, a flat bottom surface, a peripheral side edge including a back edge and left and right side edges converging towards one another and meeting at a nose of the plate member. A strap passes through elongate slot openings in the plate member to allow the plate member to be secured to a user's hand with the back of the user's hand engaged against the top surface of the plate member. Hook components of a hook and loop fastener on the bottom of the plate member allow for releasable attachment of a non-scratch scouring pad thereto. The scouring pad is generally configured to match the shape of the plate member as defined by the outer peripheral edge.
