Flexible Windshield Cleaning Head for Single-Swipe Scrubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windshield cleaning tools require repeated rotation to apply and remove cleaning solution, and lack a mechanism for simultaneous application and removal of cleaning solution and debris, making the process laborious and inefficient.
Innovation Solution
A cleaning implement with an elongated, arcuate, flexible shaft and multiple removable attachments on the same side of the cleaning head, allowing for simultaneous dampening, scrubbing, and scraping with a single swipe, using a sponge, scrubbing brush, and wiper blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional squeegees with sponge and blade on opposite sides are used, then the tool can apply and remove cleaning solution, but the user must repeatedly rotate the handle which is laborious and reduces cleaning efficiency
Solution Approach 1:
The patent combines the sponge and wiper blade onto the same side of the handle, allowing both application and removal of cleaning solution to occur simultaneously in a single sweeping motion, eliminating the need to rotate the handle between steps
Solution Approach 2:
The cleaning implement integrates multiple functions (sponge for application, wiper blade for removal, scrubbing brush for debris) into a single tool that performs all tasks in one continuous motion, making the tool universally capable of complete windshield cleaning
2Adaptability or versatility
If a rigid, linear shaft is used in conventional squeegees, then the structure is simple and stable, but the user cannot properly orient the sponge or wiper blade on curved or angled windshield surfaces
Solution Approach 1:
The patent employs an arcuate (curved) shaft design that allows the sponge and wiper blade to conform to the curvature of windshield surfaces, enabling proper contact and orientation on both flat and curved glass surfaces without adding complex adjustment mechanisms
3Productivity
If multiple cleaning attachments are placed on the same side of the cleaning head, then simultaneous dampening, scrubbing and scraping can be achieved, but the attachments require force to be forced against the windshield
Solution Approach 1:
The arcuate shaft design naturally distributes and applies force across all attachments (sponge, scrubbing brush, wiper blade) simultaneously when the user applies pressure to the handle, allowing all components to engage the windshield surface at once without requiring excessive individual force on each attachment
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
Enables efficient and streamlined windshield cleaning by eliminating the need for repeated handle rotation and allowing multiple attachments to be forced against the windshield with applied pressure, enhancing cleaning efficiency.
Implementation Method 1
The shaft is constructed with a resilient but slightly pliable material so that a user can simultaneously force the sponge, brush and blades against a windshield by applying a predetermined amount of force to the handle

AI summary
A cleaning implement includes an elongated, arcuate shaft having a handle at a proximal end and a cleaning head at a distal end. The cleaning head includes a plurality of juxtaposed, removable attachments, such as a sponge, a scrubbing brush and one or more wiper blades. The shaft is constructed with a resilient but slightly pliable material so that a user can simultaneously force the sponge, brush and blades against a windshield by applying a predetermined amount of force to the handle.
