Air-Collider Goggles With Forced-Air Lens Repellent and Defogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard eye protective goggles and see-through face shields fail to provide effective protection against over-spray from airless paint sprayers, leading to compromised vision and fogging issues due to paint coating and moisture accumulation on lenses.
Innovation Solution
The A.C.R.G. device employs a high-velocity forced air system to create an invisible repellent force field around the lens, deflecting airborne materials and using a defogger system to eliminate internal fogging, utilizing external air supply sources like shop vacuums, leaf blowers, or blower units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard eye protective goggles are used, then eye protection is provided, but vision is severely compromised due to paint coating on lenses
Solution Approach 1:
The patent introduces a clear visor or shield as an intermediary barrier between the paint spray and the eye protection goggles. This intermediary layer allows the goggles to maintain their protective function while preventing paint from coating the goggle lenses, thereby preserving vision clarity through the goggles.
Solution Approach 2:
The protective system is divided into separate functional components: the clear visor/shield that faces the paint spray and the eye protection goggles behind it. This segmentation allows each component to perform its specific function independently - the visor blocks paint while the goggles protect eyes from debris.
2Reliability
If enclosed eye protection goggles are used, then eye protection is provided, but fogging occurs on internal lens surface due to moisture
Solution Approach 1:
The clear visor acts as an intermediary thermal barrier between the external environment and the enclosed goggle chamber. It reduces heat transfer and moisture condensation on the internal goggle lenses, thereby minimizing fogging while maintaining the enclosed protective structure.
Solution Approach 2:
The patent modifies the thermal and humidity parameters within the enclosed goggle chamber by introducing ventilation channels or anti-fog coatings that change the temperature and moisture conditions on the internal lens surface, preventing condensation and fogging.
3Loss of information
If clear visor is used to maintain vision, then vision clarity is maintained, but paint material coats the visor surface
Solution Approach 1:
The clear visor is designed as a disposable or easily replaceable component that can be quickly cleaned or replaced when painted. This low-cost, short-lived component protects the more permanent and expensive goggle system from paint contamination.
Solution Approach 2:
The patent replaces complex mechanical cleaning systems with simple aerodynamic solutions, such as air flow channels that use compressed air to blow paint particles off the visor surface, or electrostatic coatings that repel paint particles without mechanical contact.
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
Effectively prevents airborne material from contacting the lens while maintaining clear vision by repelling overspray and eliminating fogging, ensuring clear visibility during painting tasks.
Implementation Method 1
A.C.R.G. device employs a high-velocity forced air system to create an invisible repellent force field around the lens, deflecting airborne materials
Implementation Method 2
The A.C.R.G. device utilizes a high volume and pressure of the air is directed through internal chambers and restricted channels exiting on both sides of and across the exterior surface of the clear lens
Implementation Method 3
A very small amount of this forced air is directed internally, directed downward across the entire surface of the inside of the viewing lens and exhausting out of the inside of the goggles across the bottom of the lens, and in so doing, eliminates any and all fog from forming on the inside of the lens

AI summary
Eye protection goggles specifically designed to in a ‘hands free’ manner, eliminate airborne particulate materials, liquids or fluids from contacting the outer surface of the lens, as well as eliminating any fogging of the inner surface of the viewing lens.
