Adjustable Helmet with Independent Longitudinal and Lateral Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets often have limited adjustability, which can lead to inadequate fit and protection against various types of impacts during sports and other activities.
Innovation Solution
The helmet features an adjustable outer shell with independent longitudinal and lateral adjustment subsystems, allowing for precise fitting to the user's head, and includes self-adjusting padded interfaces to conform to the head's shape and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid outer shell with inner padding is used to protect against head injuries, then protection capability is improved, but adjustability to fit various head shapes and sizes is limited
Solution Approach 1:
The outer shell is divided into multiple adjustable components including a main shell, a movable rear section, and adjustable side panels. The adjustment system is segmented into independent longitudinal and lateral subsystems that can modify different dimensions of the helmet separately, allowing customization for various head shapes and sizes while maintaining the rigid protective structure
Solution Approach 2:
The helmet incorporates dynamic adjustment mechanisms that allow the rigid outer shell to be reconfigured into multiple states. The longitudinal adjustment subsystem moves the rear section forward or backward, while the lateral subsystem expands or contracts the side panels, enabling the same rigid shell to adapt to different head dimensions without compromising its protective rigidity
2Adaptability or versatility
If existing adjustment systems are used to modify helmet fit, then some adaptability is achieved, but the capacity to adjust for various head shapes and sizes remains limited
Solution Approach 1:
The adjustment system is divided into two independent subsystems: a longitudinal adjustment subsystem that modifies the front-to-back dimension by moving the rear shell section, and a lateral adjustment subsystem that modifies the width by expanding or contracting side panels. This segmentation allows each subsystem to handle specific adjustment tasks independently, increasing overall adaptability while keeping each individual subsystem relatively simple
Solution Approach 2:
The adjustment system is designed with universal components that can accommodate various head shapes and sizes through combinations of longitudinal and lateral adjustments. The same adjustment mechanisms serve multiple functions: fitting different head circumferences, adjusting for various head lengths, and accommodating different head shapes, thereby maximizing adaptability without proportionally increasing complexity

AI summary
A helmet for protecting a head of a user, in which the helmet is adjustable to adjust how it fits on the user's head, including by adjusting dimensions of the helmet independently from one another (e.g., adjusting the helmet longitudinally and laterally in independent ways) and/or having a self-adjusting padded interface with the user's head to better fit on the user's head (e.g., depending on a shape and/or a size of the user's head).
