Protective Goggle Assembly with Recessed Resilient Face Engaging Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective goggle assemblies are uncomfortable for users with wider faces or higher cheekbones due to excessive pressure from the resilient face engaging portion, and the strap disassembly process is inconvenient.
Innovation Solution
A protective goggle assembly with a goggle frame featuring recesses on the lower end for a resilient face engaging portion with curved edges, and a strap assembly system using buckles with tenons and apertures for easy assembly and disassembly, providing adjustable fit and improved ventilation through air vents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the resilient face engaging portion is pressed against the rigid goggle body to secure the goggles, then the protective function is improved, but the comfort for users with wider faces or higher cheekbones deteriorates due to excessive pressure
Solution Approach 1:
The goggle body is divided into a rigid goggle body and a separate resilient face engaging portion. This segmentation allows the resilient portion to be detached or adjusted independently, reducing excessive pressure on users with wider faces or higher cheekbones while maintaining the protective function of the rigid structure.
Solution Approach 2:
The resilient face engaging portion is designed to be flexible and adaptable to different facial contours. This dynamic design allows the portion to conform to various face shapes without excessive pressure, improving comfort while maintaining secure fit and protective function.
2Reliability
If the strap receiving member uses a flap structure to secure the strap, then the strap is held firmly, but the disassembly process becomes inconvenient requiring pushing the flap outwards and pulling the strap
Solution Approach 1:
Instead of requiring the user to push the flap outwards to remove the strap, the design inverts the operation by allowing the strap end to be pulled out directly from the strap receiving member. This simplifies the disassembly process while maintaining firm strap securing during use.
3Reliability
If the goggle frame, lens and strap are designed for stable positioning, then the assembly reliability is improved, but the assembly and disassembly time increases
Solution Approach 1:
The goggle assembly is segmented into modular components (goggle frame, lens, strap) that can be independently assembled and disassembled. This segmentation enables quick assembly and disassembly while maintaining stable positioning through dedicated connection interfaces for each component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly offers a comfortable fit for diverse facial shapes and higher cheekbones, with simple and stable assembly and quick disassembly, while enhancing aesthetics through color differentiation.
Implementation Method 1
a resilient face engaging portion is integrally formed with a rear side of the goggle frame. The resilient face engaging portion includes edges located on two sides of a lower end thereof which edges are formed with a curved shape based on a human face contour

AI summary
A protective goggle assembly has a goggle frame having a rigid goggle body formed on a front side. The goggle body has recesses formed on two sides of a lower end so that a resilient face engaging portion is integrally formed with a rear side of the goggle frame. The resilient face engaging portion includes edges on two sides of a lower end, which edges are formed with a curved shape based on a human face contour. When the goggle frame and the lens are assembled with a strap buckled to the two sides for use and with the resilient face engaging portion on the rear side of the goggle frame in contact with a user's face and cheekbones, the recesses formed on the two sides of the lower end of the rigid goggle body provide the resilient face engaging portion with a larger space for flexible adjustment.
