Inspiration

The current virus Covid-19 has made us to think about how to solve the problem with the disinfection from the perspective of engineers. Our biggest concern is that healthy people run the risk of becoming infected by catching or touching an infected product. So we decided to develop LAPURY.

What it does

It’s a disinfection box, with it we want to achieve to disinfect any product contaminated by virus, by which we refer to: Covid-19. There are three sizes for different areas and uses. Small, medium and big. LAPURY is designed to be in three main areas: business, domestic and medical use.

• In business it’s used to protect workers by disinfecting protection gear and tools as more often than not they have to share equipment between them.
• In domestic area it is useful to maintain hygiene at home, by disinfecting daily gadgets as phones or wallets...
• In hospitals and medical practices, LAPURY can disinfect the instruments used.

The disinfection process is very easy: the products inside the box will be exposed to ultraviolet light (type C). The effectiveness of Ultraviolet disinfection is around 99%.

According to European Commission data, shortwave ultraviolet light (UV-C) has a wavelength of 280-100nm. The operation of this type of lamps is given by electric current, causing an increase in energy and gas pressure. This produces photons in the form of light that act as germicide. Wavelengths shorter than 250 nm produce ozone. Within this type of light, we find UV (207-222 nm) this type of light will prevent any danger to humans.

But, How does it works?

• Firstly: by a proximity sensor, the cover will automatically open at the same time by the work of a servomotor.
• Secondly: With the hands being already disinfected, the operator will put the products to disinfect inside the box.
• Thirdly, the box will close automatically. The disinfection process using ultraviolet light will take approximately 5 minutes. The duration according to the time on the arduino is shown on the display.
• In addition, on the base of the box there is a platform to guarantee a full exposition of the product.
• When the process is finished the cover will open automatically.
• Finally the operator, again, with sanitised hands, will be able to remove the products inside the box.
• At the end of this process, all products have been fully disinfected…!!

How we built it

Electronic gadgets used:

• Proximity sensor
• Arduino
• Display
• Servomotor

Important things to keep in mind:

• Inside the box there are UV light tubes, Type C, that are being held by bolted elements attached to the box walls.
• In order to open the box there is a proximity sensor, two-articulated bars and a servomotor that pushes it.
• Is important to know that all the mechanisms are going to be outside the box and protected by a case.
• It is essential to take into account the care taken by the user in terms of personal sanitation when introducing products inside the box and removing them after the process is completed.
• The box has a rectangular shape with rounded edges.
• The whole system works with electric current connected with a cable.

Challenges we ran into

The first challenge we had was choosing between UV (ultraviolet light) or Ozone disinfection, but finally we chose UV as it is a safer method of disinfection.

Secondly, we decided to change our mechanism to open the box as our first mechanism did not take into account the design of the cover, we had to change it to an alternate mechanism of two-articulated bars.

Accomplishments that we're proud of

We have been able to make a huge progress from our initial conceptual idea to our last prototype which takes into account:

• The shape: Initial cylindrical shape into a rectangular one. To optimize the space wherever we install LAPURY.
• The sizes: Initially we had only one size of box and exclusively for domestic areas, whereas we are conscious of the importance of our product in different areas. So we have decided to develop three sizes: small, medium and large.

What we learned

As Product Design Engineer students in our second year at university, we have learned how to apply concepts to real life problems and investigating by ourselves. We have learned to overcome problems and have enthusiasm.

We have improve our skills as a team, we have listened, thought and followed through with both our teammates and mentor opinions. Doing our best in every action.

What's next for LAPURY

As future engineers we will continue working together to improve Lapury, providing solutions to fight against the pandemic. We are planning to look for investors and companies to collaborate with in order to produce a market ready product that can be sold for a decent price.
