Football Helmet with PEEK Facemask and Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current football helmets do not adequately protect against concussions and traumatic brain injuries, particularly due to their focus on linear impact absorption, neglecting rotational and translational acceleration, and lack of quick and safe facemask removal mechanisms, which can complicate injury assessment and treatment.
Innovation Solution
The development of helmets with PEEK facemasks, shock-absorbing assemblies, and quick release systems, including pivoting levers and magnetic detachers, that allow for rapid facemask detachment without tools, addressing rotational and translational impacts and enhancing safety by reducing the incidence of concussions and facilitating immediate medical attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional helmet designs with hard inflexible outer shells and compressive shock absorption pads are used, then linear impact force is spread out and transferred to the pad system, but rotational and translational acceleration forces are not adequately addressed, resulting in insufficient concussion protection
Solution Approach 1:
The helmet incorporates a rotational restraint system with pivot points and rotational members that dynamically respond to rotational forces. When rotational acceleration is detected, the rotational members engage to restrain unwanted head rotation, providing adaptive protection against concussions caused by rotational impacts while maintaining normal helmet function during non-impact activities
Solution Approach 2:
The helmet design changes the physical parameters of impact response by introducing rotational restraint mechanisms that specifically address rotational and translational acceleration. The system modifies how forces are distributed and managed by adding rotational friction members and pivot points that control rotational movement, complementing the existing compressive shock absorption for linear impacts
2Reliability
If traditional facemask attachment methods are used, then the facemask is securely attached to the helmet, but removal requires tools and significant time, delaying medical assessment and treatment of injured players
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, bolts requiring tools) with a cam-locked quick release mechanism. The cam member rotates to lock or unlock the facemask attachment, allowing rapid tool-free removal by simply rotating the cam lever, thereby dramatically reducing facemask removal time while maintaining secure attachment during play
Solution Approach 2:
The quick release mechanism uses a dynamic cam locking system that can rapidly transition between locked and unlocked states. The cam member's rotational movement provides mechanical advantage for quick release, enabling the facemask to be securely attached during activity but easily removed in emergencies without requiring tools or significant time
3Weight of moving object
If PEEK material is used for the facemask instead of traditional vinyl coated steel, then the facemask weight is reduced and flexibility is improved, but the structural strength and durability may be compromised
Solution Approach 1:
The patent employs PEEK (polyether ether ketone), a high-performance thermoplastic composite material, to manufacture the facemask. PEEK provides an excellent strength-to-weight ratio, offering both the weight reduction and flexibility improvements while maintaining the structural strength and durability required for contact sports applications

AI summary
An improved design for a helmet to reduce injuries caused by helmet-to-helmet collisions. Certain embodiments include novel quick release features that permit the detachment of a facemask from a helmet in 30 seconds or less, resulting in the ability to attend to an injured player in a rapid fashion and without the need for any additional tools to accomplish such removal. Other aspects relate to impact energy absorbing constructions, including shock absorbing systems and PEEK facemask designs, that when combined with the quick release features described, provide a superior helmet for a player's protection.
