Protective Headgear Segmented Adjustment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective headgear is inflexible and does not allow for precise adjustment to fit individual head shapes, leading to inadequate protection during athletic activities.
Innovation Solution
The use of a three-point adjustment system with hook and loop closures, combined with closed cell compression molded foam and mesh, allows for horizontal and vertical adjustments to customize the fit of the headgear to the wearer's head shape, incorporating elastic straps for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inflexible padding is used in protective headgear, then manufacturing is simpler, but the headgear cannot conform to individual head shapes, reducing protection effectiveness
Solution Approach 1:
The headgear is divided into multiple adjustable sections with independent adjustment members. The back section includes multiple adjustment members that can be independently positioned, allowing the headgear to be segmented and customized to fit various head shapes while maintaining protection effectiveness.
Solution Approach 2:
The headgear transitions from a static, fixed-size design to a dynamic, adjustable design. Multiple adjustment members allow the headgear to be dynamically reconfigured to match different head circumferences and shapes, improving protection while managing complexity through modular adjustment mechanisms.
2Reliability
If a fixed-size protective headgear is used, then the device complexity is reduced, but it cannot be precisely adjusted to fit unique head shapes, leading to inadequate protection
Solution Approach 1:
The adjustment system is segmented into multiple independent adjustment members located at different positions on the back section. This segmentation allows for precise, multi-dimensional adjustment to fit unique head shapes while keeping each individual adjustment mechanism simple and easy to operate.
Solution Approach 2:
Different adjustment members are positioned at specific locations on the back section to address local fitting requirements. Each adjustment member provides localized control over specific areas of the headgear, enabling precise customization without requiring complex overall adjustment mechanisms.
3Manufacturing precision
If multiple adjustment members are added to customize the fit, then the fit precision is improved, but the device complexity increases
Solution Approach 1:
The complex fitting requirement is broken down into multiple simple adjustment members positioned at different locations. Each adjustment member handles a specific aspect of the fit, dividing the overall complexity into manageable segments that are individually simple but collectively provide high precision.
Solution Approach 2:
The adjustment members are designed with universal functionality, using standard components that can be positioned at multiple locations. This multi-functionality approach allows the same basic adjustment mechanism to be replicated across different positions, achieving high fit precision without proportionally increasing overall device complexity.

AI summary
A protective headgear and headgear adjustment system is described. An example protective headgear may comprise a front section comprising padding configured to conform to a shape of a head of a wearer, a back section attached to the front section. The back section may comprise one or more adjustment members adjacent an opening in the back section. The protective headgear may comprise one or more pads configured to removeably attach to the adjustment member to define a horizontal adjustment and a vertical adjustment of the back section and at least partially cover the opening in the back section.
