Integrally Molded Goggle Frame with Exhaust Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional goggles used in laboratories and chemical plants suffer from poor air permeability, discomfort, and deformation under changing external conditions, leading to inadequate sealing and reduced protective capabilities due to loose connections and complex manufacturing processes.
Innovation Solution
The goggles feature a main frame with integrally molded exhaust valves and a nose pad supporter, utilizing a male and female connection system and clamping grooves to ensure tight connection, along with a double bowl-shaped exhaust valve design for improved ventilation and sealing, reducing assembly complexity and enhancing mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional eyepatches use assembled components, then manufacturing flexibility is improved, but the components get easily deformed and connections become loose under changing external conditions
Solution Approach 1:
The patent integrates multiple components (frame, lens holder, buckles, nose pad supporter) into a single integrally molded main frame structure. This eliminates separate assembly joints that would deform under external conditions, while maintaining manufacturing efficiency through one-step injection molding of the entire goggle framework.
2Strength
If traditional eyepatches use hard material for protection, then protective capability is improved, but comfort deteriorates and deformation occurs easily under external conditions
Solution Approach 1:
The patent employs different materials for different functional parts: the main frame uses a rigid material for structural strength and protection, while the nose pad supporter and lens use softer, more flexible materials for comfort and adaptability to facial contours, creating a composite structure that balances protection and comfort.
3Ease of operation
If traditional eyepatches add waterproof and breathable devices at through holes, then air permeability is improved, but mechanical strength weakens and manufacturing complexity increases
Solution Approach 1:
The patent removes the through holes and separate waterproof-breathable devices from the frame structure. Instead, it integrates ventilation function directly into the molded main frame with exhaust valves, eliminating the need for additional components that would weaken the structure and complicate manufacturing.
4Ease of repair
If traditional eyepatches use assembled components, then ease of repair is improved, but the goggle deforms during long distance transportation and protective capability weakens
Solution Approach 1:
The patent creates a unified integrally molded main frame that prevents relative movement and deformation of components during transportation. The single-piece construction eliminates assembly joints that are prone to breaking or separating, ensuring structural stability while maintaining protective capability.

AI summary
Goggles include a main frame of goggles, a lens, an exhaust valve and a nose pad supporter. The exhaust valves and the nose pad supporter are disposed on the main frame of goggles and are integrally molded with the main frame of goggles. The main frame of the goggles is wrapped outside the lens, and the lens is clamped in the main frame of goggles. The goggles can keep tight structure and have a good air permeability, and prevent blood and other liquids from spattering into the goggles.
