About
Bamboo poles outside HDB flats tend to get very heavy when laden with clothes
When it is too heavy, it not only dangerous for the user (falling accidents), it is also dangerous for other residents (falling poles).
An invention that simplifies the process of bringing the clothes in and out of the house by minimizing weight.

Target Audience
Elderly with weak arms (main) when alone, act of bringing poles out is dangerous (causes falls)
People who do laundry in HDB flats (maids, housewives)
Extent of the Problem
Due to doing laundry, a maid lost her life
Extent of the Problem
http://smj.sma.org.sg/5003/5003a6.pdf “… Home injuries (67.9 percent) were the most common, followed by road-related injuries (21.2 percent). 85.3 percent of the injuries were due to falls. 49.9 percent of the patients were admitted to hospital.”
Gait/Weakness/Imbalance stands to be the highest %.
Our Design
Window
Socket Pole
Special detachable hangers attached to Steel Wire
How it works
Clothes will be hung on hangers which are hung on crimp knots on the steel wire. When the handle is turned, the wheels next to the pole would turn and the hangers would move towards the window. The user would be able to remove clothes one by one. The crimp knots would move in a circular motion.
*Wheel made bigger for illustration purposes
What is crimping?
Hanger Design
A carabiner will be used to attach the hanger to the loop.

Existing Solutions
Retractable Lever System
Why our Invention?(How it beats the current solutions?)
More effective in minimizing weight
Our pole can remain outside(vs. bringing the pole back in), meaning minimum weight, thus reducing the stress on hands if elderly have to bring the clothes in.
Safety
No need to bring the pole back in the house AND as such it minimizes the risk of falling accidents and poles dropping/falling.
Comparison- Ours vs OthersOur Invention Retractable lever system
- Pole remains outside
- Individual clothes are
taken in
- Less weight elderly need
to bear when drying
clothes
- Pole is still taken into the
flat
- All the clothes are taken
in at once
- The pole laden with
clothes can be very heavy
Comparison- Ours vs OthersOur Invention Conventional Method
- Pole remains outside
- Individual clothes are
taken in
- Less weight elderly need
to bear when drying
clothes
- Individual hangers require
less strength to
counteract effects of wind
- Pole is taken in and out of
the flat repeatedly
- All the clothes are taken
in at once
- The pole laden with
clothes can be very heavy
- Wind makes it even
harder
Estimated Price
Below $20
Limitations
Unable to hang heavy blankets and bedsheets
Pole might get dirty when left outside
Wire may expand/contract slightly during hot/cold weather
Slightly costly
