I remember several nfl players wearing a padded shell in the 90s.I've always thought padding the outside would make a big difference in concussion impacts. I tried pulling a patent on the idea, but it was long since taken.
Yeah I’m surprised there hasn’t been more innovation, or I may just be unaware of it.This is one area that the technology sure seems like we could do better...
It won't ever stop it completely, but if you can lengthen the amount of time for the stopping of the skull, you will reduce the force on the skull. Impulse = Force x timeEven a helmet made from vibranium won't stop this...

the issue with that point is this requires the assumption that the force that hits the external surface is what matters. it's moreso about the ability to slow the time to stop of an object inside the shell (ie the yolk) than it is to protect the shell, which is exceedingly hard to do and something that just adding padding to the outside. this kind of stuff has been around for decades. unless you can create a mechanism in which the body and the head both can be slowed gradually or you eliminate shoulder hitting/spearing and move more toward rugby style tackling (ie head up, wrapping up), you won't see a tangible lowering in concussions because inside the shell the brain will continue to move at the same speed it was before unless you slow the overall tackle (ie make the players slower or change the form of tackling that's currently being done).It won't ever stop it completely, but if you can lengthen the amount of time for the stopping of the skull, you will reduce the force on the skull. Impulse = Force x time
Impulse also equals change in momentum which is mass x change in velocity. No matter what you do the change in velocity will be the same (coming to a stop), but if you can increase the time it takes to cause the velocity to reach zero, the force on the skull will be less. This is the idea behind airbags or how if someone tossed an egg to you, you would catch it by lengthening the catch time. Increasing the time to stop reduces the force on the egg and the egg doesn't break because you've reduced the force to a point that the shell can withstand it.
This is a nice video that explains the concept (at the 7 minute mark it gets into how this factors into safety considerations):
And thus concludes today's physics lesson.
The same physics apply to the yolk as the shell. I'm not saying it's an easy solution and I'm sure people that understand the physics are working on it, but I'm convinced we can do better.the issue with that point is this requires the assumption that the force that hits the external surface is what matters. it's moreso about the ability to slow the time to stop of an object inside the shell (ie the yolk) than it is to protect the shell, which is exceedingly hard to do and something that just adding padding to the outside. this kind of stuff has been around for decades. unless you can create a mechanism in which the body and the head both can be slowed gradually or you eliminate shoulder hitting/spearing and move more toward rugby style tackling (ie head up, wrapping up), you won't see a tangible lowering in concussions because inside the shell the brain will continue to move at the same speed it was before unless you slow the overall tackle (ie make the players slower or change the form of tackling that's currently being done).
So replace concussions with Death?The best way to take concussions out of football would be to go no helmets.
I think he's assuming it would be like rugby and people would run and hit differently.So replace concussions with Death?
are they going to ban blocking, the forward pass, and stop breaks in between plays too. Taking away helmets is a ridiculous take for footballI think he's assuming it would be like rugby and people would run and hit differently.
No one is going to tackle stupid without a helmet.So replace concussions with Death?
Many believe you are correct. They’d tackle differently without a helmet. The weight of the helmet also takes acclimating.No one is going to tackle stupid without a helmet.
Not a perfect solution but would help with concussions. I’m sure other issues would arise.Many believe you are correct. They’d tackle differently without a helmet. The weight of the helmet also takes acclimating.
have you played football? it is impossible to tackle with perfect form keeping your head out of the tackle every time, also how are lineman suppose to block and get off the ball ,they always bang heads. There are so many issues taking helmets away would cause way more problemsNo one is going to tackle stupid without a helmet.
The increased time of deceleration comes from an increased distance of deceleration. The air bag begins to decelerate the drivers head about a foot before it hits the steering wheel. That is what gives the greater time and less force. This is impossible to duplicate in football where only very minor changes can be made in the distance and time of the collisions.It won't ever stop it completely, but if you can lengthen the amount of time for the stopping of the skull, you will reduce the force on the skull. Impulse = Force x time

I played 4th - 7th grade. Came home with a headache from every practice because the helmet was so tight.I've always wondered why players now are able to simply slide their helmet on and off by the facemask with zero effort. Seems to me a loose helmet leads to less protection. I could be wrong. Our helmets always ripped the ears off as you removed the dang things.
