Disposable Wiper Attachments With Surfactants for Insect Debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing desiccated insect debris from vehicle windshields, such as windshield wipers and wiper fluid, often smear the debris or require additional cleaning tools, and there is a need for a system that minimizes user exposure and is disposable.
Innovation Solution
A chemically-impregnated material, such as surfactants and microencapsulants, is integrated into disposable windshield wiper attachments, handheld tools, and wiper fluid formulations to facilitate efficient removal of insect debris without modifying the wiper blade design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If windshield wipers and wiper fluid are used to remove insect debris, then the cleaning process is simple, but the debris is often smeared across the windshield
Solution Approach 1:
The patent changes the chemical parameters of the cleaning system by introducing chemically-impregnated materials with specific surfactant compositions and pH levels (pH 2-14) that chemically interact with insect debris to facilitate its breakdown and removal without smearing, while maintaining the simple wiper operation
Solution Approach 2:
The patent introduces a chemically-impregnated intermediate material (wiper sleeve or attachment) that acts as a mediator between the wiper blade and the windshield. This intermediate layer contains chemicals that directly contact and break down the insect debris, preventing direct smearing by the wiper blade while maintaining operational simplicity
2Manufacturing precision
If additional cleaning tools are used to remove desiccated insect debris, then debris removal effectiveness improves, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated system: the wiper blade, the chemically-impregnated sleeve/attachment, and the chemical formulation work together as one unified cleaning system. This combination provides effective debris removal while requiring no additional separate tools or complex multi-step processes
Solution Approach 2:
The patent employs disposable chemically-impregnated wiper sleeves or attachments that are discarded after use. This disposable approach ensures each cleaning operation has fresh, effective chemicals without requiring complex maintenance, refilling, or cleaning of reusable components, thereby maintaining simplicity while ensuring effectiveness
3Duration of action of moving object
If wiper fluid is depleted and water sources are located, then cleaning can continue, but time and convenience are lost
Solution Approach 1:
The patent applies preliminary action by pre-impregnating the wiper sleeve or attachment with sufficient cleaning chemicals before use. This preliminary chemical loading ensures the cleaning system can operate through multiple windshield cleaning cycles without requiring external water sources or fluid refilling, eliminating time losses and maintaining cleaning continuity
Solution Approach 2:
The chemically-impregnated material contains its own cleaning agents and moisture (in the case of pre-moistened wipes), making the system self-sufficient. The embedded chemicals and moisture serve the cleaning function without requiring external water sources, enabling the system to be self-service and independent during operation
4Manufacturing precision
If methyl alcohol is used in wiper fluid, then insect debris can be removed, but desiccated debris remains difficult to remove
Solution Approach 1:
The patent changes the chemical parameters by using a broad pH range (pH 2-14) and various surfactant types instead of relying solely on methyl alcohol. These chemical parameter changes enable effective breakdown of desiccated insect debris through chemical hydrolysis and surfactant action, overcoming the limitations of alcohol-based formulations
Solution Approach 2:
The patent employs composite cleaning formulations that combine multiple chemical components including surfactants, solvents, and pH-adjusting agents. This composite chemical system provides synergistic effects that enhance the removal of desiccated debris beyond what any single component (including methyl alcohol) could achieve alone

AI summary
Presently disclosed are embodiments of devices for expedient removal of insect and other debris from vehicle surfaces including windshields. A surfactant-based chemical impregnation of porous material is central to various tools used for such cleaning. Embodiments include a wiper attachment and tools for dispensing disposable chemically-impregnated pads. A disposable windshield wiper blade attachment that incorporates chemicals that will expedite insect and other debris removal when attached to the wiper blades and the wiper action is performed. The attachment can take the form of fabric, foam, or other porous enclosure of synthetic or natural material that is impregnated with chemicals or pressure-sensitive micro-encapsulated surfactant formulations that will facilitate rapid removal of the windshield and automobile surface debris.
