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

VSEngineering 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

Engineering Contradiction:
Improveeye protectionVSAvoiduser comfort
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If a secure lens attachment mechanism is implemented, then lens stability is improved, but device complexity increases

Engineering Contradiction:
Improvelens stabilityVSAvoidattachment mechanism complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

3Productivity

If moisture management features are added, then performance is improved, but device complexity increases

Engineering Contradiction:
ImproveperformanceVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
