Customized Goggle Design with Dynamic Nosepiece and Flexible Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing goggles fail to accommodate anatomical facial differences, particularly in eye spacing variations, leading to poor fitting and watertight seals, as they often have fixed nosepieces that do not allow independent adjustment of eyepiece distance and conformability to facial contours.
Innovation Solution
A goggle design featuring a strap with adjustable, 3-axial movement nosepiece and eyepieces that can flex and rotate over the eye socket, coupled with a sealing pad that conforms to facial contours, allowing for customizable fit and airtight/watertight seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed nosepieces are used in goggles, then manufacturing simplicity is maintained, but adaptability to different facial anatomies deteriorates
Solution Approach 1:
The nosepiece is designed with dynamic adjustment capabilities, allowing it to change position and configuration based on user needs. The nosepiece can be adjusted along the bridge of the nose and rotated to accommodate different facial angles and anatomies, transforming a static component into a dynamic one that adapts to individual users.
Solution Approach 2:
The goggle system is divided into modular components including the nosepiece, eyepieces, and sealing elements that can be independently adjusted or replaced. This segmentation allows each component to be optimized for specific functions while maintaining overall system adaptability to different facial structures.
2Stability of the object's composition
If eyepieces are fixed in position, then structural stability is maintained, but conformability to eye sockets deteriorates
Solution Approach 1:
The eyepieces are designed with rotational joints and flexible mounting mechanisms that allow them to rotate and adjust their orientation independently. This enables the rigid eyepiece structure to maintain stability while adapting its angular position to conform to the contours of the user's eye sockets and orbital bones.
Solution Approach 2:
Different parts of the goggle system have different degrees of flexibility and rigidity. The eyepieces maintain rigid lens structures for optical stability while their mounting mechanisms and surrounding frames provide localized flexibility for anatomical conformity. The sealing pads provide additional localized compliance at the contact points with the face.
3Reliability
If gel sealing pads are used, then watertight seal is improved, but conformability to facial contours deteriorates
Solution Approach 1:
The sealing system uses soft gel pads at the specific contact points with the face, while the surrounding frame structure maintains its rigidity for structural support. This localized application of compliance allows the seal to conform to facial contours without compromising the overall structural integrity of the goggle.
Solution Approach 2:
The sealing pads are designed with variable thickness and durometer properties that allow them to deform and adapt to different facial geometries. The gel material's viscoelastic properties enable it to flow and conform to the unique contours of each user's face while maintaining sufficient firmness to create an effective watertight seal.
4Ease of manufacture
If one size fits all design is used, then manufacturing cost is reduced, but fitting precision deteriorates
Solution Approach 1:
The goggle incorporates multiple adjustable elements including the nosepiece position, eyepiece orientation, and strap tension that allow a single standardized design to be dynamically adapted to fit different facial sizes and shapes, achieving custom-fit precision without requiring multiple size variants.
Solution Approach 2:
The adjustable nosepiece and eyepiece system is designed to accommodate a wide range of facial anatomies through multiple adjustment mechanisms, making a single goggle model universally applicable to diverse users while maintaining precise fitting through the combination of adjustment options.
