Abstract

Here in the presented research report, The Engineers (authors) have developed the rotating barrier

as an obstruction to maintain the social distancing with the help of the CAD software. Authors followed

the design engineering methodology and prepared canvases for the development, Created mind mapping,

and Designed with the help of standard design guidelines also modeling by CAD tool. The rotating barrier

obstruction can establish in front of the general store door or ticket counters (and any place where the

crowed of humans is create and its required to convert in row) to create social distancing as a safeguard to

COVID-19. Also, for this project, Authors (Engineers) assumed (with empathy thinking) the working

condition for the user. Also, in this paper, the Author (Engineers) has introduced the new concepts for the

buyer in the rotating barrier as a name MCT (Momentary Critical Time) and RCT (Required Critical

Time) & Free Time (FT) for the buyer with JT (Judgment Time) for the store owner.

I. INTRODUCTION

The whole world is affected by the COVID-

19; for preventing COVID-19 infection, do not

leave home is important. But it is compulsorily

required to leave home to buy necessary things.

Now, in this situation, as per the advice of WHO

and Government guidelines, maintaining social

distancing is more important. In more populated

countries like China and India, the maintenance of

social distancing is very difficult. The author

(Engineer) invented the Metal – wooden structure

to establish in front of the shop or store door.

The structure introduced by the Engineer;

the rotating barrier is the structure of steel or wood

to make the obstruction between the two things, two

or more peoples, etc.

A revolving door generally consists of two

or more wings that hang on a center with bearings

and rotate around a vertical axis within a cylindrical

enclosure.

RESEARCH ARTICLE OPEN ACCESS




Generally, obstructions like barrier are used

for controlling the traffic on the road as well as the

highways. Moreover these barriers are also used as

a check post point by the traffic police. Also, the

grill barriers are used for the crowed control in the

ticket counter of the railway, theatre, airport, etc.

Revolving Barrier Are Used Mostly in Garden

Door.

Different type customers are available in the

world, some customers Take More time as per their

body health. So, it is required to introduce the

critical times.

Definition of the newly developed concepts (For

rotating barrier as per this project): MCT, RCT,

CT.

Momentary Critical Time (MCT): when both

customers are in the barrier the first customer is

going for extruding and another customer is going

for the buying.

Required Critical Time (RCT): when the one

customer is entering or extruding, another customer

is implicate in the barrier.

Free Time (FT): when the one customer is buying,

another buyer is lifted from the barrier and his place

is being empty. The empty place will automatically

lock as per the design of the barrier stand. The

buyer who is buying can take time as per his want.

Judgement Time (JT): For the seller, when the

seller put the required things on the rotating plate

and the buyer put the payment money on the plate.

Now the plate is rotating and the times come when

the money and things are parallel but both are

middle in between buyer and seller. This time may

be possible the buyer can take both, and go away.

II. METHODOLOGY

Authors (Engineers) followed the guidelines

given by the GTU India for developing the solution.

The prepared the canvas is converted in to the table

format; as a Framework.

AEIOU Frame work is used in this project

for the observation of the actual field as A-Activity,

E-Environment, I-Interaction, O-Objects, U-Users.

Sad Story

The Indian government

announced the people must

create a minimum of 2 mitres

social distance between each

other but many people’s can not

aware of it. So it can create a

spread of infection of the

viruses.

Happy story

If any obstruction is created;

then, the social distance is must

be automatically followed.

VII. CONCLUSION

The product explained in this research

project can help the whole world to prevent the

infection to COVID-19. Also, it can help the store

keeper to manage crowd in front of the shop. Also,

any place where required human crowed converts to

row and rotation. The Position of the rotating plate

and position of the rotating barrier is totally

independent to each other. Also, the future scope of

the presented product is immense. In future weather

protecting kit can be installed in this device to

protect the customer from heavy rain or from

sunlight during the hot summer days. And can

install a huge umbrella over the device which will

protect the customer from the mentioned problems.

The Author (Engineers) introduced the new

concepts for buyer in the rotating barrier as a name

MCT (Momentary Critical Time) and RCT

(Required Critical Time) & Free Time (FT) for

buyer during buying with Judgment Time (JT) for

store owner. Every buyer always wants this, the

Minimum RCT and Maximum FT. these concepts

of the Critical positions, RCT, MCT, FT, and JT

can be useful for future work, and also, can be the

deep research subject for the scientist and

engineers. And can help to solve the more related

Questions.
