Story

INTRODUCTION

In view of the current situation the COVID-19 has become ubiquitous in every corner of the world. We must aim at preventing the community spread of the virus. To achieve this we must make sure a proper social distance is maintained from individual to individual. To make sure that a proper social distance is maintained from individual to individual we are coming up with the idea of social distancing cap.

SOCIALDISTANCINGCAP

To achieve the above problem and diminish the spread of virus at community level we are coming up with the social distancing cap which is a reminder of social distancing.

The main aim of the cap is to make sure a proper distance is maintained among individuals so that community spread of virus can be diminished. Here ultrasonic sensors are installed on three sides of the cap so it that measure the minimum distance to be maintained by the individual in 360 degrees. Also a buzzer is installed which alerts the individual by giving a buzzer upon not maintaining a minimum distance. The reason to design this social distancing reminder in form of a cap is that compared to a band or a belt this would of easy use. As cap is a commonly used item by every person be it a child or an adult. In case of a band, the band may not measure the distance in 360 degrees. And the sensors should be exposed so, in case of a belt the person must tuck his shirt which may not be comfortable to everyone.

We are using 3 ultrasonic sensors which are placed at 3 sides of the cap as shown in the cad design. so using this we can maintain proper social distance among individuals. If the proper social distance is not maintained in three directions this cap will alert the person. To alert the person we are using buzzer.

CONCLUSION

So we the team THE INNOVATORS are coming up with the idea of social distancing cap which serves as a social distancing reminder. Using this product community spread of virus can be diminished as this ensures the proper maintenance of distance among individuals.
