The proposed technology is a kinetic energy dissipation system composed of a cutting member and a sacrificial deformation tube. Upon impact, the device, shaped like a steel wheel with four spoke-like blades, cuts through the sacrificial deformation tube causing the metal to stretch in addition to being cut, rather than crumple unevenly. This technology is designed to allow only a predetermined magnitude of force to be transmitted through the system to the receiving body. This one-time use device is capable of dissipating high levels of energy including those from explosive devices. The intent of the device is to limit the energy to the receiving body (for example human occupants in a vehicle) to a level so that they would not be severely injured by the impact. The simplicity of the technology design enables it to be easily and inexpensively manufactured. Experimental results revealed that in tests employing the use of different axial loads (ranging from the equivalency of slow-moving vehicle collisions to explosives) and different velocities, the proposed technology can effectively dissipate the kinetic energy of various impact forces with very similar results. Technologies designed to minimize the impact of high energy shock forces have the potential to reduce critical and life-threatening injuries, mainly applicable in instances of vehicle accidents and military explosions. Each year approximately 170 000 Canadians are injured in automobile accidents, with over 2000 reported fatalities in 2014. The automotive industry has responded by putting safety at the forefront; advanced vehicle safety is no longer restricted to premium vehicles and is now commonly installed in entry level vehicles. On a global scale, the automotive safety system market is expansive, encompassing 24.3 billion USD in 2013. The proposed technology can be used to dissipate and/or absorb a set amount of energy that can be incorporated into an automobile, a military vehicle, a crash barrier, or other structures to dissipate the kinetic energy of a shock or impact force. This novel energy dissipation system has the potential to reduce critical injuries and save lives in instances of high energy impact.

该技术是由切割构件和牺牲变形管组成的动能消能系统。在撞击时，这个形状像钢轮的装置有四个辐条状的刀片，切割牺牲的变形管，导致金属在被切割的同时拉伸，而不是不均匀地皱缩。这项技术被设计成只允许通过系统向接收体传递预定大小的力。这种一次性使用装置能够消散高水平的能量，包括爆炸装置产生的能量。该装置的目的是将流向接受体(例如，车辆中的人类乘员)的能量限制在一定水平，以便他们不会在撞击中受到严重伤害。技术设计的简单性使其能够轻松且廉价地制造。实验结果表明，在采用不同轴向载荷(从慢行车辆碰撞到炸药的当量)和不同速度的试验中，该技术可以有效地耗散各种冲击力的动能，结果非常相似。 旨在将高能冲击力的影响降至最低的技术有可能减少危重和危及生命的伤害，主要适用于车辆事故和军事爆炸。每年约有17万加拿大人在车祸中受伤，2014年报告的死亡人数超过2000人。汽车行业的回应是把安全放在首位；先进的汽车安全不再局限于高端汽车，现在普遍安装在入门级汽车上。在全球范围内，汽车安全系统市场规模庞大，2013年市场规模达243亿美元。建议的技术可以用来耗散和/或吸收一定数量的能量，这些能量可以结合到汽车、军用车辆、防撞栅栏或其他结构中，以耗散冲击力或冲击力的动能。这种新型的能量消散系统有可能在高能量冲击的情况下减少危重伤害并挽救生命。
