@Cabe: Very true you have a good point on it but we have to consider the safety of the children 1st isn't it ?

Interesting, combine that with Muscatine Middle School's 'The Sleeve' and a bullet-proof backpack and blanket and our kids should be safe and secure. Why not just use telepresence robots or keep the kids at home and attend 'virtual school' instead? Schools are starting to look awfully similar to prisons nowadays but I guess you can't be too careful when it comes to your child's safety. What a sad state of affairs.

Just a few follow up points.

Coming from NE Ohio, our original path followed both steel and aluminum extruding.  The steel piece at this size was too weighty during our prototyping testing with many teachers, did not slide rapidly into place, and was not nearly as quiet as it needs to be.  The aluminum extruding was a challenge due to the wide range of thicknesses needed to both slide under a door, yet be thick enough to prevent both inward and outward swinging operation.

The impact modified polycarbonate survived all of the testing requirements we placed on the device.  Lightweight, but strong.  It also survived ballistic testing, impact testing, and continuous pressure testing.

Coming from a school administration background, it was never my intent to say this is a magic solution.  Safety is a multi-layered process in any public setting.  We work with mental health professionals, anonymous tip lines, open communications, threat assessment teams, and more.

This device was designed for those (hopefully) rare moments when seconds count.  Even if law enforcement is on the scene in 5 minutes, my teachers are the first responders to care for their students.  We wanted something that could be deployed in seconds, withstand more than 4,000 pounds of force, alert administration, and still allow for accelerated egress when that time comes.

No perfect solution and a rather sobering topic to address.

I won't wax political on an Engineering website, but a barricade is truly addressing the symptom of a greater ill.

tek,

Out of curiosity, what would you say the cause is?

 

And if I were designing this, I wouldn't mess around with plastic.  What is wrong with steel for this design?

Elizabeth, I feel the same way and I'm really at a loss for words when I see technology applied to such a horible social problem.  I've always felt that the best solution is one that addresses the cause rather than the effect.

When I considered writing this article it made me feel a bit nervous to even have to cover something like this. It's a scary sign of the times that people are developing inventions to protect children and teachers from shooters. It seems a shame they should have to, and that more can't be done to prevent these scenarios from even occurring. No matter, it's good that people are thinking of new ways to protect people when they do, even if it shouldn't be necessary. I think this sounds like a good start to trying to block off doors in classrooms quickly, but there is more that can be done to prevent these shootings themselves.

During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
It's been two years since the Mac Mini's last appearance on iFixit's teardown table, but a newly revised version joins Apple's lineup this week.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
