Sport Goggle Lens Attachment and Moisture Gutter Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sport goggles and glasses suffer from discomfort due to seals and gaskets that contact the user's face, affecting user comfort and performance during sports activities.
Innovation Solution
The design incorporates inward- and outward-facing protrusions on the goggle lens that engage with corresponding engagement pockets and latches on the frame, securely holding the lens in place, while also featuring a gutter to direct moisture away from the eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seals and gaskets are used to protect the eyes, then eye protection is improved, but user comfort deteriorates due to contact with the face
Solution Approach 1:
The patent removes traditional seals and gaskets that contact the face, replacing them with a foam liner that lines the interior of the frame without direct facial contact. This extraction of the harmful sealing mechanism eliminates discomfort while maintaining eye protection through the lens and frame structure.
2Stability of the object's composition
If a secure lens attachment mechanism is implemented, then lens stability is improved, but device complexity increases
Solution Approach 1:
The lens attachment mechanism is divided into separate functional elements: engagement pockets in the frame, protrusions on the lens, and latches for securing. This segmentation allows each component to perform its specific function independently, achieving secure attachment while keeping the overall system relatively simple and modular.
3Productivity
If moisture management features are added, then performance is improved, but device complexity increases
Solution Approach 1:
The foam liner serves multiple functions: it provides interior lining for comfort, manages moisture through its material properties, and contributes to the overall structural integrity of the goggle. This multi-functionality improves performance without adding separate dedicated moisture management components.
