Introduction - Cart
The cart is a key tool for the collectors.
They use it to gather all garbages from the
bins and send them to the waste collection
station.
However, current cart design is not user
friendly. It is very big and bulky. In fact,
from our interviews, we realized some
collectors even purchase their own
carts in hardware shops or buy different
accessories to modify the cart (for example
adding strings to hang their belongings) to
suit their needs.
Idea
It is nearly impossible to design one single cart to fit all conditions given how
different the streets of Hong Kong area, not to mention all the different needs
of the collectors. So we want to propose a modular cart that collectors can
adjust based on their needs and context. Here are they key design criteria:
1. Minimal Effort - Most collectors are in their 50s to 70s. We want to make it as
effortless as possible for them to move the garbage from bins to the cart to
prevent any injury.
2. Easy Navigation - Streets of Hong Kong are in general quite narrow with lots
of pedestrians and in some cases, quite steep. We have seen garbage falling
out of the carts, cart crashing into people and other incidents during our
observation. The new design has to enable collectors to navigate in different
conditions easily.
3. Storage - Currently almost all collectors will hook some strings at the metallic
handle of their cart to hang different bags for their personal belongings
(water, lunch box, wallet, tools etc). This is not hygenic and user friendly
(bags moving back and forth when pushing the cart forward). In our new
design, we want to make sure there is safe storage space for collectors.
