Segmented Helmet Padding System for Impact Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective headgear fails to adequately mitigate the negative health effects of high-force impacts experienced in contact sports, such as wrestling and football, due to insufficient impact absorption and distribution.
Innovation Solution
A helmet padding system comprising a rigid shell with slots and a spacing pad made of elastomeric material, which includes a central portion and extending portions to absorb and dissipate impact forces laterally, providing enhanced impact resistance and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective headgear is used, then basic impact protection is provided, but the negative health effects of high-force impacts are not adequately mitigated
Solution Approach 1:
The rigid shell is divided into multiple sections by slots, creating central and side portions that can independently deform and absorb impact energy. This segmentation allows different regions to handle impact forces differently, improving overall protection effectiveness while reducing harmful stress concentrations.
Solution Approach 2:
The system combines a rigid shell structure with elastomeric spacing pad material to create a composite protective system. The rigid shell provides structural integrity and initial impact resistance, while the elastomeric material provides additional cushioning and energy absorption, together mitigating harmful impact effects more effectively than conventional single-material headgear.
2Strength
If a rigid shell structure is used to provide impact resistance, then structural strength is improved, but the ability to absorb and dissipate impact energy is reduced
Solution Approach 1:
The rigid shell is segmented into central and side portions by slots, allowing these sections to move independently during impact. This enables the structure to absorb impact energy through controlled deformation of individual segments while maintaining overall structural strength, resolving the contradiction between rigidity and energy absorption.
Solution Approach 2:
The elastomeric spacing pad acts as an intermediary element between the rigid shell and the user's head. It absorbs and dissipates impact energy that passes through the rigid shell, preventing this energy from being transmitted directly to the head, thus maintaining structural strength while improving energy absorption.
3Reliability
If the rigid shell covers the entire head, then comprehensive protection is provided, but comfort and breathability are reduced
Solution Approach 1:
The rigid shell is divided into central and side portions by slots, creating openings that improve breathability and reduce the feeling of confinement. This segmentation maintains protection coverage by keeping the shell structure in place while allowing air flow and reducing heat buildup, thereby improving user comfort.
Solution Approach 2:
The slots are strategically positioned to provide breathability and comfort in specific regions where heat and moisture accumulation would be most problematic, while maintaining full protection coverage in impact-prone areas. This local modification of the shell structure balances protection and comfort requirements.

AI summary
Helmet padding systems are disclosed. One helmet padding system includes a rigid shell and a spacing pad. The rigid shell is configured to cover a top of a user's head and be worn under a piece of headgear. The rigid shell includes a pair of slots extending in a direction from a lower rear edge of the rigid shell toward a lower front edge of the rigid shell. The pair of slots define a central portion and opposed side portions of the rigid shell. The central portion includes at least one pair of flaps, with each of the at least one pair of flaps extending outwardly from the central portion into a respective slot. The central portion further includes a tail extending outwardly from the central portion into each of the slots. The spacing pad is positioned within the rigid shell. The spacing pad includes a layer of elastomeric material.
