Interchangeable Goggle Lens With Integrated Heating Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles lack easily interchangeable lenses and effective anti-fogging mechanisms, making them unsuitable for varying weather and lighting conditions, and prone to fogging during physical activity, which can impair vision and pose safety risks.
Innovation Solution
The design incorporates a semi-rigid anterior portion with a flexible posterior for comfortable fit, a tongue-and-groove or cap-and-ridge engagement mechanism for easy lens interchange, and an electrical heating element connected to a battery for anti-fogging, allowing simultaneous lens attachment and power connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional goggles use a fixed lens design, then the goggle structure is simple, but the lens cannot be easily interchanged when lighting conditions or terrain visibility requirements change
Solution Approach 1:
The goggle is divided into separable components: a removable lens and a goggle body with an engagement mechanism. The lens can be detached and replaced independently from the goggle body, allowing users to interchange lenses based on lighting conditions and terrain requirements without replacing the entire goggle assembly.
Solution Approach 2:
The engagement mechanism incorporates a resilient body member that can be deformed to release the lens and a latch member that can be actuated to secure or release the lens. This dynamic mechanism allows the lens to be firmly held during use but easily removed when needed, providing adaptability without excessive complexity.
2Reliability
If conventional goggles use a resilient body with groove and peg engagement, then the lens can be retained, but repeated lens interchange causes the body to lose resiliency, break, or crack
Solution Approach 1:
The engagement mechanism is designed with a latch member that positively secures the lens in place, distributing the mechanical stress away from the resilient body member. This prevents the body from being repeatedly stressed during lens interchange, avoiding loss of resiliency, breaking, or cracking while maintaining easy lens removal and installation.
Solution Approach 2:
The original reliance on purely elastic deformation of the resilient body for lens retention is replaced with a mechanical latch engagement system. The latch member provides a positive mechanical engagement that does not depend on the repeated elastic cycling of the body material, thereby preventing fatigue failure.
3Reliability
If conventional goggles lack anti-fogging mechanisms, then the goggle structure remains simple, but fogging occurs during physical activity and impairs vision
Solution Approach 1:
The lens incorporates an anti-fogging coating or treatment that changes the surface properties of the lens to prevent condensation and fogging during physical activity. This maintains clear vision without adding mechanical complexity to the goggle structure.
Solution Approach 2:
The lens is constructed as a composite structure, combining the base lens material with an anti-fogging coating or treatment layer. This composite approach provides both the optical clarity needed for vision and the anti-fogging functionality to prevent impairment during exercise, without significantly increasing overall device complexity.
4Reliability
If conventional goggles require multi-step lens replacement procedures, then lens security is maintained, but the time and effort required for lens interchange increases
Solution Approach 1:
The engagement mechanism is pre-configured with a latch member and resilient body member positioned to automatically engage with the lens upon insertion. This preliminary positioning allows the lens to be secured with a single snapping motion rather than requiring multiple adjustment steps, reducing interchange time while maintaining secure retention.
Solution Approach 2:
The complex multi-step retention mechanism is extracted and replaced with a simple latch-based system. The latch member can be quickly actuated to release the lens, and the resilient body member provides automatic retention without requiring additional adjustment steps, thereby reducing the time and effort for lens interchange.
