Goggle Lens Assembly Quick Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles often lack comfort, fit, and ventilation, leading to fogging and debris entry, and have complex lens replacement processes, while also being heavy and non-environmentally friendly.
Innovation Solution
The design features a flexible, lightweight body made from recyclable materials with a ventilation system, a quick change lens attachment, and a dual lens assembly for improved fog resistance, comfort, and ease of use, using a combination of soft and rigid foams, and a unique lens mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional goggles use rigid or semi-rigid shells for mechanical strength, then structural support is improved, but comfort and fit deteriorate
Solution Approach 1:
The goggle frame is divided into multiple components: a rigid shell providing structural support, flexible foam pads for comfort, and a separate lens assembly. This segmentation allows each component to fulfill its specific function optimally without compromise.
Solution Approach 2:
The goggle combines rigid materials (for the shell and frame structure) with flexible foam materials (for padding and comfort elements). This composite construction enables simultaneous achievement of mechanical strength and wearer comfort.
2Ease of manufacture
If conventional goggles lack ventilation systems, then manufacturing simplicity is improved, but fogging and debris entry worsen
Solution Approach 1:
The goggle incorporates porous foam materials in the padding and ventilation structures. These porous materials allow controlled air flow for fog prevention while filtering out debris, addressing both ventilation needs and protection requirements.
Solution Approach 2:
Ventilation features are strategically positioned in specific locations on the goggle frame and lens assembly. This localized approach provides effective ventilation where needed while maintaining overall manufacturing simplicity and structural integrity.
3Reliability
If conventional goggles use complex lens replacement processes, then lens security is improved, but ease of operation deteriorates
Solution Approach 1:
The lens attachment mechanism uses dynamic elements such as spring-loaded retention clips or snap-fit systems that securely hold lenses during use but allow quick removal when needed. This dynamic design provides both security and ease of replacement.
Solution Approach 2:
The goggle frame includes pre-positioned retention features and guide structures that automatically align and secure lenses during attachment. This preliminary preparation of mounting features simplifies the replacement process while ensuring secure installation.
4Strength
If conventional goggles use heavy materials, then durability is improved, but weight worsens
Solution Approach 1:
The goggle employs composite construction combining lightweight rigid materials (such as lightweight polymers or composite plastics) with flexible foam components. This composite approach maintains structural durability while significantly reducing overall weight compared to traditional heavy materials.
Solution Approach 2:
The goggle frame and components utilize thin-walled rigid structures and flexible foam shells that provide necessary strength and protection with minimal material thickness, thereby reducing weight while maintaining durability.
