Helmet Comfort Liner Adjustable Device for Head Shape Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmets face challenges in achieving a secure and comfortable fit for diverse head shapes and profiles, leading to potential pressure issues and reduced field of view due to improper positioning.
Innovation Solution
An adjustable device for the comfort liner, comprising a liner suspension device and cushioning pad, allows for customizable internal height and angle adjustments via removable coupling means engaging with anchor points on the impact absorbing liner, ensuring a stable and comfortable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the helmet uses a fixed comfort liner design, then the manufacturing process is simple and cost-effective, but the helmet cannot adapt to different head shapes and profiles causing improper positioning
Solution Approach 1:
The comfort liner is divided into multiple independent adjustable sections (front section, rear section, and side sections) that can be independently positioned. Each section can be adjusted separately to match the wearer's head shape and profile, allowing customization without requiring a completely custom-molded liner for each user.
Solution Approach 2:
The comfort liner transitions from a static fixed design to a dynamic adjustable system. The liner includes movable sections that can be repositioned along the impact absorbing liner using adjustment mechanisms, enabling the comfort liner to adapt its shape and position based on the wearer's head morphology.
2Adaptability or versatility
If the helmet is designed to fit a specific head shape, then the fit is secure and comfortable for that shape, but it cannot accommodate users with different head shapes and profiles
Solution Approach 1:
Different sections of the comfort liner are designed with different adjustability characteristics suited to local requirements. The front section can be adjusted to accommodate varying forehead shapes and eye levels, while the rear section adapts to different occipital bone shapes. Side sections can be positioned to match individual ear and temple contours, providing localized customization for each body region.
3Ease of operation
If the comfort liner is made soft and comfortable, then wearer comfort is improved, but the helmet stability and security on the head may be compromised
Solution Approach 1:
The comfort liner is segmented into multiple sections that can be independently adjusted to match the wearer's head shape. This segmentation allows the liner to conform to the head contours more effectively, maintaining stability while preserving comfort through customized fit rather than relying solely on material softness.

AI summary
A helmet which includes an impact absorbing liner and a comfort liner. The comfort liner in turn includes at least one adjustable device which during the normal use of the helmet is positioned on the top of the head of the user. The adjustable device is suitable for being fastened to the impact absorbing liner of the helmet by coupling suitable for being removably engaged on the impact absorbing liner of the helmet via a plurality of anchor points. By changing the anchor point where the adjustable device is engaged, the user is allowed to adjust the conformation and slope of the adjustable device of the helmet according to his own needs.
