Goggle Facial Cushion Embossed Pattern Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sports like motocross and skiing, goggles cause sweat to drip into the eyes due to insulation, leading to discomfort and lens fogging, and when worn with helmets, the goggle straps cause the cushion to gap, allowing particulates to irritate the eyes and increasing wind circulation.
Innovation Solution
A facial cushion with an embossed pattern that increases the surface area for sweat wicking and evaporation, and thicker end portions to maintain contact with the face even when the goggle frame opens, reducing sweat entry and fogging, and creating an air space for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the goggle provides insulation to prevent dirt and snow from entering the eyes, then eye protection is improved, but sweat accumulation increases causing discomfort and lens fogging
Solution Approach 1:
The cushion is divided into multiple functional zones: a wicking material layer for sweat absorption, an embossed pattern layer for creating air spaces, and a foam padding layer for sealing. This segmentation allows each layer to address specific problems - the wicking material handles sweat, the embossed pattern enables cooling air circulation, and the foam provides the seal for eye protection.
Solution Approach 2:
The embossed pattern creates localized air spaces between the cushion and the wearer's face, allowing cooling air circulation in specific areas while maintaining overall sealing. The pattern includes raised surfaces that contact the skin and depressed surfaces that create air gaps, providing localized thermal management without compromising the overall eye protection function.
2Stability of the object's composition
If the goggle strap is wrapped around the exterior of the helmet to secure the goggle, then goggle stability is improved, but the cushion gaps away from the face allowing particulates to enter
Solution Approach 1:
The cushion features locally enhanced thickness at the left and right end portions, creating thicker sealing zones at the temples where the strap applies force. This local reinforcement ensures that even when the strap pulls the goggle frame outward against the helmet, the thicker cushion material maintains contact with the face and prevents gaps that would allow particulate entry.
Solution Approach 2:
The cushion is pre-formed with varied thickness distribution, with thicker end portions positioned at the temples before the goggle is worn. This beforehand cushioning anticipates the outward pull from the helmet strap and ensures sufficient material is available at the critical sealing points to maintain contact with the face under load.
3Ease of operation
If the cushion is made thinner to reduce bulk, then comfort is improved, but the cushion cannot maintain contact with the face when the goggle frame opens
Solution Approach 1:
The cushion employs non-uniform thickness distribution, with thinner middle portions for comfort and thinner profile, and thicker end portions at the temples for maintaining contact. This local quality variation allows the cushion to be comfortable in the central facial areas while having sufficient thickness at the temples to resist the outward pull from the helmet strap and maintain sealing 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
The embossed pattern enhances sweat removal and evaporation, reduces fogging, and maintains contact with the face, ensuring comfort and clear vision during sports activities, while the thicker end portions prevent the cushion from lifting off the face when wearing a helmet.
Implementation Method 1
The facial cushion may define an interface surface. The interface surface may have a raised surface and a depressed surface. The raised surface may directly contact a wearer's face for wicking sweat away from the wearer's face
Implementation Method 2
the embossed pattern increases the total surface area of a wicking material thereby increasing the rate at which sweat is removed from the wearer's face and evaporated
Implementation Method 3
The depressed surface may be gapped away from the wearer's face when worn. This provides an air space between the wearer's face and the depressed surface
Implementation Method 4
the embossed pattern increases the total surface area of a wicking material thereby increasing the rate at which sweat is removed from the wearer's face and evaporated

AI summary
A facial cushion for a goggle may have a plurality of layers which provide cushioning, cooling and ergonomic fit functions. The top layer which contacts the wearer's face may have an embossed pattern which creates an air space between the wearer's face and the top layer for providing a cooling function. The embossed top layer also increases the total surface area of the top layer thereby increasing its wicking ability and reduces the total skin contact surface area of the top layer reducing heat. Additionally, the cushion may be thicker at left and right end portions to maintain contact with the wearer's face despite pulling of the left and right ends of the goggle when the goggle is worn with a helmet.
