Origami-based Deployable Shelter Structure for Refugees

a module

 8 modules are used for real-scale model

 Planar figure scale is 4 m × 5.3 m

Two modules size compared to human

• The deployable shelter uses origami structure.

• Very small on folded state and easy to transportation.

• On the locking state, the shelter is strong enough to hold itself making

• Suitable for refugee applications.

(38)

Tricycle for Rice Transplanting

 Prototype

• A rice planter which uses simple 4 bar mechanism and a tricycle for rice planting.

• It is simple, easy to operate and can be very cheap options to the complex rice planter .

(39)

IMPROVE YOUR MOBILITY: Multifunctional walker

• The mobility walker solves problem of traditional walker in which the user has trouble while passing narrow corridor or door.

• The adjustable height and the cane mode helps the user to adjust the walker based on the surrounding.

• 6 walkers were donated to urban slum.

Free to walk regardless of path widths

Convenient in stair climbing

(40)

Vaccine carrier using ice pack

• Modification to the traditional vaccine carrier.

• It controls the fans to cool the vaccine and maintains the system within 2-8 degrees.

• The solar PV powered system helps to provide the necessary energy to run the

controller and the fans.

(41)

Give a Choice to Your Feet!” Adjustable High heel shoes

• Provides the facility of adjusting height of the ladies shoe.

• The heel is safe, strong and even maintain aesthetic at smaller heel.

(42)

Development of a movement-assisting board powered by rowing

• The movement assisting board helps disabled person for locomotion.

• The lower center of gravity makes it more stable and the rowing

movement helps easier locomotion.

(43)

Vaccine Delivery- Back-pack carriers with modules

• The back pack type vaccine carrier are easier to carry.

• The peltier based system helps to maintain the temperature 2-8 degreesrequired for the vaccine and prevent vaccine from freezing or overheating.

Integrated Safety System

• A safety assistant mostly helpful for severely physically disabled person who cannot move and are mainly confined to wheel chair.

• The safety jacket is equipped with sensors which measures temperature and position of the person and sends alert to caretaker if the person falls down or have other some problems

(45)

Push-up Supporter

• Push up supporter helps physically disabled person especially for the people who lost their arm.

• It supports push-up and helps them to maintain their physical health.

Clamping & Releasing Push–up Supporter

(46)

Food waste disposal equipment for single person family

• This product can be used to separate water from the food waste

• It helps in disposing food waste properly.

• The miniature nature of the product makes it viable as commercial product.

(47)

The Wind powered Vaccine Battery Charger

• Portable wind power generating option is the on-the-go power supplier for the vaccine carrier.

• It can be manufactured using scrap computer fans and locally available material to provide power to the vaccine carrier.
