NISHA

Trashcan

Designing a trashcan, suitable for small environments

Personal Project

l  8 Weeks

The Significance of the problem

As the population grows, economics flourish, and we are living on the same planet as we were living since the beginning, we are facing numerous contemporary problems. One of these problems is the lack of space. Accommodations are getting smaller in most countries, and offices are changing into shared spaces. So we need to make smarter use of these limited spaces.

The change in house size in UK between 1930 and present time, with specific study on individual rooms.

Trashcan

One of the mundane necessary objects in every house and office is a trashcan. The aim of this project is to find a solution to make more/better use of trashcan in different places. Now, crowded offices and cramped rooms need more productive trashcan that can solve the existing problems. the products available in the market have a particular focus on aesthetics for both office and house environments.

Empathy Interview

In a series of empathy interviews, several questions were conducted indirectly regarding the trashcans, and key problems were identified. As a result of this one full working day communication with house-holds and employees of a governmental department, new issues exposed themselves, which wasn’t initially stated by the users.

Nisha

Nisha is trashcan designed to solve several problems such as size, accessibility and smell. It has four lids that open in opposite directions

Nisha means Blossom

The difference

The entrance of NISHA is shaped like a pyramid. These four lids open by a push through a link. Four edges of an inserted trash bag are hooked to each side, and when the lids are open, the trash bag’s end would be wide open as well.

How does it work?

The mechanism of NISHA is similar to other regular pedal trashcans. However, instead of moving one lid, the pedal is connected to a crossbar that pushes all four lids by a set of links.

One major challenge in this design was to identify hoe the trashcan could be placed up against a wall from one or more sides if four lids open in four different directions and expand the entrance.

To solve this problem, the center of the crossbar should have a gap to freely wiggle around its center. This way, for instance, while three lids are totally open, one can be half open as the crossbar is tilted and leaned towards the opposite direction.
