Helmet Cheek Pad Ventilation Using Reticulated Air Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection helmets for motorcycling suffer from inadequate ventilation, particularly in the cheek pad region, leading to discomfort and reduced concentration due to limited breathability and convection heat exchange, especially during prolonged use or extreme conditions.
Innovation Solution
Incorporation of a padding layer with reticulated portions and air conveyor means that channel ventilation air from the chin guard to these portions, utilizing additive manufacturing or 3D printing technology to maintain porosity and breathability, with optional mechanical throttling mechanisms to regulate airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional sponge cheek pads are used, then comfort function is provided, but breathability is limited and convection heat exchange is restricted
Solution Approach 1:
The patent replaces traditional solid sponge cheek pads with a reticulated structure that has a porous framework. This reticulated cheek pad maintains the comfort function while providing numerous channels for air circulation, significantly improving breathability and convection heat exchange in the cheek region.
Solution Approach 2:
The patent introduces air conveyor means specifically positioned to deliver ventilation air to the reticulated cheek pad region. This localized air delivery system enhances breathability where it is most needed (in the cheek area) without compromising the overall comfort function of the padding layer.
2Reliability
If ventilation openings are formed in the helmet, then air circulation is enabled, but control of air flows inside the helmet is difficult
Solution Approach 1:
The patent incorporates adjustable air conveyor means that can regulate the flow of ventilation air to the reticulated cheek pad. This dynamic control mechanism allows the user to adjust air flow according to environmental conditions and personal comfort needs, solving the problem of uncontrollable air flows while maintaining effective ventilation.
3Strength
If the visor is closed, then protection is provided, but the zone between user's face and visor becomes prone to misting up
Solution Approach 1:
The patent uses a flow of ventilation air as an intermediary between the user's breath zone and the visor surface. This air flow acts as a protective barrier that prevents moisture condensation on the visor while allowing the visor to remain closed for protection, thus eliminating the harmful misting effect.
