Helmet Shield Shock Absorbing Mountings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports helmets have limited shock absorption capabilities due to the restricted size of doughnut-shaped mountings, which restrict their ability to effectively absorb impact from balls or other objects.
Innovation Solution
A helmet design featuring a protective shield with shock-absorbing elements and fastener arrangements that secure the shield to the helmet shell, utilizing resiliently deformable materials and keying formations to absorb and distribute impact forces circumferentially, providing all-round protection for the head and neck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If doughnut-shaped mountings are used to attach the grille to the helmet shell, then the grille can be secured to the helmet shell, but the shock absorption capability is restricted due to the limited size of the mountings
Solution Approach 1:
The invention divides the shock absorption function into multiple segments by using multiple shock absorbing mountings distributed around the helmet shell, rather than relying on a single large mounting. Each mounting is engaged with the grille at different locations, allowing the cumulative shock absorption capability to be enhanced while maintaining a distributed attachment structure.
Solution Approach 2:
The invention transitions from a two-dimensional surface attachment to a three-dimensional spatial distribution of shock absorbing mountings. The mountings are positioned at multiple locations around the helmet shell, utilizing the third dimension (radial distance from the head) to increase the effective shock absorption area without increasing the footprint on the helmet shell surface.
2Strength
If multiple shock absorbing mountings are used to increase shock absorption, then impact force distribution is improved, but the device complexity increases
Solution Approach 1:
The shock absorbing mounting is designed as a multi-functional component that simultaneously performs several functions: it attaches the grille to the helmet shell, absorbs shock impacts, and provides structural support. This universal design reduces the need for separate components for each function, thereby managing device complexity while achieving improved impact force distribution through multiple mountings.
