Do you know that there is no one who is responsible for evacuation of wheelchair users in case of emergencies like fire in buildings?

As outlined in the Regulatory Reform (Fire Safety) Order 2005 which is adopted by many countries, it’s not the role of the Fire Service to facilitate safe evacuation of non-domestic premises but the service provider’s responsibility to evacuate people from a building in an emergency. Owners of the building need to ensure that there is available escape means accessible for all people in case of emergency including emergency stairs, safety rooms and evacuation equipment for the disabled. But in case of emergency people’s basic survival instincts is triggered and if you do not have big attachment with the disabled person, you probably do not risk your life to assist them to safety which consumes high period of time to get to evacuation when helping a wheelchair user. This is because you need to lift them to evacuation equipment which will take very valuable time and that is if there is available equipment. Elevators and other electronic evacuation equipment will not work because an emergency usually involves a power cut.

This project is about building a new kind of building stairs that is very accessible for wheelchair users to evacuate the premises in case of emergency. This is done by combining a ramp with a spring system to continuously adjust the slope of the stairs. The main impossible challenge of building a ramp in building stairs is that the slope will be too high and adjusting to the right angle will not be possible because of distance limitation. But this simple mechanism will solve this problem by using a mass spring system to adjust the slope of the ramp at all times. Meaning, the maximum slope for a ramp is 18 degrees which this mechanism has and a person with a wheelchair will go down in case of emergency without any problem or a need of additional evacuation equipment by themselves. As the wheelchair user reaches the end of the 18 degree slope he/she will be at the top of a mass spring that compresses when a load F is applied on it with lower velocity V. This will enable them to reach the final tread of the stair completing the floor riser. As they step off the ramp, the spring will stretch attaining its original height for others to do the same task. All the wheelchair users have to do it repeat the same process until the ground level, evacuating without any help of any kind. The ramps can also be used by all people including physically fit people and all kinds of physically disabled people because in case of emergencies running on the stairs is a bit dangerous if one is not careful and slope grounds are better than stairs when traveling at a fast pace. When the ramp is not being used for an emergency it can be attached to the hand rail of the stairs.

    I have dedicated my life for invention and research because not only I have big dreams but also it is my only way out of poverty. We all have a talent we know or did not find out yet. Mine happens to be inventing. I discovered this talent of mine when I was in second year student during my university life. Starting from that point everything seemed not important except creating new ideas. So, until now I have invented more than 50 inventions which are new to the world and the rest are intended for Ethiopia that will change the life of many people including mine. But because of poverty, theft and many reasons I could not manage to make it. But all that matter is I will never give up. I will invent until and after I become successful. That makes me a strong entrepreneur. My skills are aided with a mechanical engineering degree on design, production and sales expertise.
