4. Toothbrush Concept Design
Problem Statement
 In India alone it is estimated about 1 billion toothbrushes, representing more than 25000 tonnes of waste are
discarded & end up in landfills every single year.
 These toothbrushes are made from combination of plastic(made from crude oil) & rubber for the hand piece, nylon
for bristles and mix of plastic & cardboard for packaging.
 Currently none of these items are bio-degradable and therefore they remain in landfills indefinitely.
 Worst they end up in our oceans & washed up on our beaches or consumed by marine life.
 If they are burnt, they release a combination of toxic and green house gases.

5. Toothbrush Concept Design
Need analysis
 Durability and usability are the most important things.
 Design should have good materials for both the body and the head of the brush.
 Easy cleaning and drying after use.
 Replaceable bristle head to minimize landfills since bristles are the first to wore out.
 Aesthetically pleasing and reasonable price.
 Size should be comfortable to hold and grip.

15. Vegetable peeler concept
Problem statement
 Currently available peelers are difficult to grip in one hand.
 Peeling rate is low since holding conditions are not so comfortable.
 Difficult to remove peeled waste which gets stucked in the gap between the blades.
 Most of the blades are not replaceable.
 Sharping the blade edge is not easy and not possible is some peelers.

16. Need analysis
 Minimal design with less material.
 Replaceable blade.
 Better grip.
 Long lasting blade and durable body.
 Faster peeling rate.
 Can accomodate different sets of blades for different purpose.

20. Pencil sharpener concept
Problem statement
 Currently available sharpeners are difficult to grip for children.
 Removal of waste is not so easy.
 Design is not optimised for children.

21. Need analysis
 Minimal design with less material.
 Replaceable blade.
 Better grip.
 Long lasting blade and durable body.
 Faster peeling rate.
 Can accomodate different sets of blades for different purpose.
