Windshield Cleaning Composition for Protein-Based Bug Splatter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bug splatter on vehicle windshields is difficult to remove due to its protein content and the inability of typical wiper blades to handle solids, leading to smeared visibility and the need for manual scrubbing, especially when the vehicle is in motion.
Innovation Solution
A chemical composition combining a surfactant, chaotropic agent, and solvent, applied to the windshield, which denatures proteins and enhances solubility, allowing for easy removal using conventional wiper blades without soaking or vigorous wiping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If typical windshield wiper blades are used to remove bug splatter, then liquid wiping function is provided, but bug splatter is smeared across the windshield and visibility deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by incorporating specific concentrations of surfactants (0.1-10% w/v), chaotropic agents (1-10% w/v), and solvents. These parameter changes enable the composition to effectively dissolve and lift bug splatter proteins, allowing wiper blades to remove rather than smear the contaminants
Solution Approach 2:
The cleaning composition acts as an intermediary substance between the wiper blade and bug splatter. The surfactants and chaotropic agents in the composition mediate the interaction by chemically breaking down the protein structure of bug splatter, enabling the wiper blade to effectively remove the contaminant without direct mechanical smearing
2Quantity of substance
If water-based windshield washer fluids are used, then liquid coverage is provided, but bug splatter is not sufficiently removed and smearing occurs
Solution Approach 1:
The patent fundamentally changes the chemical composition parameters from simple water-based fluids to a sophisticated formulation containing surfactants (0.1-10% w/v), chaotropic agents (1-10% w/v), and specific solvents. These parameter changes enable the fluid to penetrate and dissolve protein-based bug splatter while maintaining adequate coverage area
Solution Approach 2:
The cleaning composition is a composite material combining multiple functional components: surfactants for wetting and emulsification, chaotropic agents for protein denaturation, and solvents for dissolution. This composite approach provides both adequate coverage and effective bug splatter removal, overcoming the limitations of simple water-based fluids
3Object-affected harmful factors
If bug and tar cleaners are applied and soaked for minutes, then bug splatter can be scrubbed off, but the process requires extended time and manual scrubbing
Solution Approach 1:
The cleaning composition performs preliminary chemical action on bug splatter proteins through surfactant penetration and chaotropic agent denaturation. This preliminary chemical breakdown occurs during the wiping process itself, eliminating the need for extended soaking times and manual scrubbing that were required by conventional products
4Object-affected harmful factors
If vigorous mechanical forces are applied with cloth and cleaning composition, then bug splatter can be removed, but manual intervention is required and the process is complex
Solution Approach 1:
The patent replaces the mechanical scrubbing system with a chemically-active cleaning composition. The surfactants and chaotropic agents perform the cleaning function through chemical mechanisms rather than mechanical force, allowing standard wiper blades to remove bug splatter without requiring manual scrubbing with cloths
Solution Approach 2:
The cleaning composition is self-activating upon contact with bug splatter. The surfactants and chaotropic agents automatically penetrate and denature the protein structure of bug splatter, enabling the system to clean itself without requiring external manual intervention or vigorous mechanical action

AI summary
A chemical composition for removing bug splatter from a glass substrate is provided that includes a surfactant present in an amount of 1 to 30 total weight percent of the composition. A chaotropic agent present in an amount of 5 to 20 for inorganic salts and 15 to 40 for organic chemicals total weight percent of the composition. A solvent is present in which the surfactant and chaotropic agent are dissolved. A method cleaning bug splatter debris from a transparent substrate, such as a windshield, is also provided. The composition is applied to bug splatter debris and the transparent substrate to solubilize the bug splatter debris. The composition and the bug splatter debris are then wiped from the transparent substrate.
