Goggle Assembly Ventilation Duct and Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective goggles for sports and activities suffer from inadequate thermoregulation, leading to fogging and heat buildup, which can be dangerous during strenuous exercises like motorcycling, where adjusting the goggles is difficult and unsafe.
Innovation Solution
A goggle assembly with apertures at the upper end of the frame and/or lens, a duct for air venting, and an adjustable valve to control airflow, allowing for active heat removal without user input, ensuring comfort and preventing fogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional goggles are used during strenuous exercises, then eye protection is provided, but thermoregulation is inadequate leading to fogging and heat buildup
Solution Approach 1:
The goggle assembly is segmented into multiple functional components: the frame, lens, ventilation ducts with adjustable valves, and sealing elements. This segmentation allows independent optimization of each component - the frame provides structural support and protection, while the ducts and valves independently manage thermoregulation, resolving the contradiction between protection and temperature control
Solution Approach 2:
The adjustable valves on the ventilation ducts enable dynamic parameter changes in airflow rate and direction. Users can modify the ventilation parameters in real-time based on activity intensity and environmental conditions, allowing the system to adapt between maximizing eye protection (reducing airflow) and optimizing thermoregulation (increasing airflow)
2Temperature
If goggles are adjusted manually to remove heat, then thermoregulation improves, but safety deteriorates during high-speed activities
Solution Approach 1:
The goggle assembly performs thermoregulation automatically through passive airflow mechanisms and pre-configured ventilation ducts. The system serves itself by utilizing natural pressure differentials and body heat to drive airflow through the ducts, eliminating the need for manual adjustment during high-speed activities while maintaining effective heat removal
Solution Approach 2:
The ventilation system is designed with flexible ducts and adjustable valves that can be configured before activity. The system dynamically adapts to changing conditions through passive airflow responses to body movement and environmental changes, providing continuous thermoregulation without requiring active user intervention during strenuous exercise
3Temperature
If ventilation apertures are added to the frame, then airflow and thermoregulation improve, but structural integrity and protection may be compromised
Solution Approach 1:
Ventilation apertures are strategically positioned in specific locations on the frame where they provide maximum airflow benefit while minimizing impact on overall structural integrity. The apertures are located in non-critical areas of the frame structure, and their size and shape are optimized to provide adequate ventilation while maintaining frame strength and protective function
