2021 James Dyson Design Award - LIGHTAID



Teacher Wang Hongxiang of the Department of Engineering Design and the concurrent teacher Wu Changchi jointly instructed students Guo Xinyuan and Ni Weixing to design the first aid equipment "LightAid", and won the 2021 James Dyson Design Award Taiwan Preliminary Award of Merit. They will represent Taiwan on the international stage and compete with 28 countries from all over the world. Or regional design experts will compete for a high prize of 30,000 pounds, and have more opportunities to implement design concepts in daily applications.

What is it:
LIGHTAID, a project by Nicholas Prawirani and Guo Xin-Yuan, makes it easier for bystanders to give CPR. According to Prawirani, statistics have shown that people typically feel tired and cannot continue to apply enough force for proper CPR after two minutes. LIGHTAID aims to solve this problem by utilizing a hydraulic press that amplifies the force applied by a  rescuer. This conserves the rescuer’s  energy  and helps facilitate more effective rescue.

What can it do:
LightAid aims to help bystander performs more efficient CPR. By using Pascal's law to enhance force, rescuers can reserve more energy to perform longer effective CPR. LightAID also comes with a built-in AED to increase a patient's survival rate.

We ever witnessed a situation where an adult collapsed on the floor due to sudden cardiac arrest. Because the location was in an alley, emergency help's arrival time might be affected. Besides calling for help, most of the bystander did not do anything because did not know what to do when cardiac arrest occurs. They do not know the proper technique and strength required in performing CPR. Also, after performing CPR for about one and a half minutes, a bystander will start to get exhausted, resulting in less and less effective CPR. These problems let our team wanted to create something to support bystanders perform more efficient first aid.

How it works:
LightAID is here to help those experiencing sudden cardiac arrest. It contains AED and CPR mechanisms. The AED in lightAID is the same as any other AED on the market right now, with voice prompts and reminder lights. What makes LightAID different is that there is Pascal's hydraulic system in it. According to Pascal's principle, a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. This can increase the force applied to them. To make the force larger, the pressure is applied to a larger area. With increased force, it can reserve more energy to perform longer effective CPR.

Why is it different?
The integrated CPR mechanism in LightAID makes it stands out from the others, with also loads of other features. 1)LightAID contains CPR in an AED device yet portable so it can be stored in a lot of public places. 2) The straps are used to tighten the device with the body, so it stays still when performing CPR. The strap also contains aluminum wires to make it stiff and steady when pressed just by using the weight of the arms instead of the whole body, so the rescuer does not need to lift the whole body when installing the device. 3) LightAID comes with two important functioning lights, a CPR reminder light to let rescuers know if they do it right and an AED shock warning light to warn the rescuer when AED is about to deliver a shock. 4)The triangular-shaped device helps the AED pads conveniently stored to both nearest areas of the body where AED pads are supposed to be placed.

Future plan:
Our team hopes by bringing this concept theme to the public may increase awareness about sudden cardiac arrest and why basic first aid knowledge is essential in our life.
