Winter Precipitation Barrier Coating for Windshield Adhesion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windshield washer fluids effectively remove vision-obscuring materials but fail to prevent their deposition on windshields, requiring excessive fluid and mechanical effort for removal.
Innovation Solution
A winter precipitation barrier composition comprising a retaining agent and a solvent, optionally with auxiliary components, that prevents deposition and facilitates the removal of winter precipitation by reducing adhesion and enhancing tenacity on the windshield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional windshield washer fluid is used to remove vision obscuring materials, then the materials can be washed away, but substantial amounts of fluid and mechanical action are needed and removal causes undesired delays
Solution Approach 1:
The patent applies preliminary action by pre-treating the windshield with a coating composition that creates a low-adhesion surface before vision obscuring materials are deposited. This preliminary protective layer prevents strong adhesion, making subsequent removal much easier and faster without requiring substantial mechanical action or time
Solution Approach 2:
The patent uses an intermediary approach by introducing a coating composition as a mediating layer between the windshield and vision obscuring materials. This intermediary layer reduces the adhesion force between the materials and the windshield surface, allowing for easier and quicker removal with less fluid and mechanical effort

3Ease of operation
If traditional windshield washer fluid is used, then it can assist in removal of vision obscuring materials, but it fails to prevent their deposition on the windshield
Solution Approach 1:
The patent applies universality by designing a coating composition that performs multiple functions simultaneously: it prevents the deposition of vision obscuring materials while also facilitating their removal if they do accumulate. This dual-functionality eliminates the need for separate prevention and removal strategies
Solution Approach 2:
The patent applies preliminary action by pre-treating the windshield with a coating composition that creates a low-adhesion surface before vision obscuring materials are deposited. This preliminary protective layer prevents strong adhesion, making subsequent removal much easier and faster without requiring substantial mechanical action or time
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 composition significantly reduces the deposition of vision-obscuring materials on windshields and makes their removal easier, reducing delays and fluid usage while maintaining effectiveness in low temperatures.
Implementation Method 1
making it easier to remove any vision obscuring material that has accumulated... reductions in the degree of adhesion of any accumulated winter precipitation to a windshield will facilitate the removal of such winter precipitation from said windshield
