DESIGN NAME:
Self-Disinfecting Seat
PRIMARY FUNCTION:
Self disinfecting seat
INSPIRATION:
All across the world, at this time of uncertainty about COVID-19 pandemic, people need a safer condition to go to hospitals, dr. offices, restaurants and workplaces, or even using public transportation. On the other hand, the continual disinfection of public used seats is very hard, and sometimes impossible. A self disinfecting chair can be helpful and effective in providing safer conditions for people.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
A self-disinfecting chair! The chair is covered with a shell that is illuminated by ultraviolet lights residing on the inside of the chair. The lights start activating for a set amount of time, when the weight is lifted off, without any weight on it, to prevent ultraviolet light penetrating human skin. The chair occupant's weight pressure provides energy source for the lights. The chair can be used on public places, especially in hospitals. Its cover could also be used on other surfaces.other surfaces, and ground floor.
OPERATION / FLOW / INTERACTION:
A self-disinfecting seat or chair can be used in public places such as hospitals, subways, buses, doctor offices, restaurants and etc. When the person gets up from the chair, it automatically turns on for a set period of time, disinfecting itself. This is to avoid exposing people to ultraviolet lights, The conversion of energy obtained from weight to electricity is done by electric crystals. The shell can also be used on other surfaces, and even floor coverings in hospitals or other public places.
PROJECT DURATION AND LOCATION:
This project started at the beginning of May and was completed at the end of May of 2020 in Karaj/Iran.
FITS BEST INTO CATEGORY:
Furniture Design

PRODUCTION / REALIZATION TECHNOLOGY:
The chair is made up of a body, a disinfectant shell, and a weight-to-electricity converter. The self-disinfecting shell consists of a high density polyethylene plastic layer and a series of very small ultraviolet lamps placed within a certain distance apart. After the occupant gets up from the chair, the shell automatically lights up from the inside for a certain period of time and disinfects the chair surface. This chair uses electric crystals to convert and store weight energy into electricity.
SPECIFICATIONS / TECHNICAL PROPERTIES:
The thickness of the High Density Polyethylene (HDP) plastic layer is between 1 and 1.5 cm. Ultraviolet lamps are the size of LED lamps. The dimensions of the chair can change depending on the type of use, but in general, standard overall dimensions for chairs used in hospitals, subways, and public places is usually 75X60X110 cm^3.

RESEARCH ABSTRACT:
Ultraviolet lights have long been used in operating rooms and infectious wards of the hospitals for disinfection. In the current condition, this technology could be used in public places for disinfection. The research on this project has been done using scientific, medical and engineering publications, credible authentic internet sites. The research on characteristics of HDP plastics and the reaction of COVID-19 virus on it has also helped with design on this project.
CHALLENGE:
The biggest challenge on this was the design and operation of UV lights, due to the fact that UV lights are harmful to humans. This design challenge is controlled by having the lights turn on and off in a timely manner and when the chair is unoccupied. Another challenge on this project was to have a design so there is no external energy source, and it is controlled by using the energy of the weight of the occupants and converting it to electricity, The last challenge for me has been, not being able to access reputable internet scientific and news sites, in Iran since all external sites are filtered. To combat this challenge, with great difficulty, I have used anti-filter softwares.
