OCHA 2.0

Self Initiated Project


My journey through the tea gardens

Tea has been around for millennia. Everybody loves tea. "Tea time" or "Afternoon tea" is an indispensable part of our society. It has been the second most consumed beverage on the planet after water and has been a huge part of culture in countries forming major part of ceremonies, trade route and even starting revolutions.

Everyone should have that perfect cup of tea every single day.  For those who don’t have time to brew a cup or even own a thermometer to make sure the water is just hot enough, a need for smart brewer comes up. 

Research methods used: 

  • Contextual Enquiry

  • Interviews

  • Shadowing

  • Task flow analysis 


A smart way for your cuppa..!!

Do you love a cup of your personalised tea for a morning energy boost to start the day? Or maybe you prefer to wind down with a herbal, chamomile tea before bedtime. Whether you like herbal, black, green, red, or white teas, ‘Ocha’ can make that perfect cuppa ready when you want. A personalised tea maker that can cater to your nose and palate.

The widespread popularity and culture of tea in India paves the need to cater the elderly and the big families to present day nuclear families and novice users. There are a host of things to take into consideration when preparing your tea. Ranging from brewing to steeping to the right temperature with an ideal water to leaf ratio can make every cuppa suit as per your tastebuds. The perfect pot is personal to the drinker.



My focus in this project

To understand and design a smart tea maker kettle which can prepare varied kinds of tea for varying taste buds of Indian household by innovation and IOT technology.

The Stirrer

Ocha has a unique way of stirring the ingredients. It has a rotating platform that holds the glass bowl in place with the help of electromagnetic groove, which is eccentric to its rotating axis. The circular metal ring at the bottom of the glass bowl falls in line with the electromagnetic groove on the base, ensuring that the bowl is firmly held. This position thereby helps the bowl to move along an eccentric path, which in turn ensures thorough stir of the ingredients within it.

The glass bowl is sleek and ergonomically designed, such that the spout does not get in contact with the inner wall during its eccentric rotation. The inner surface of the bowl which is directly opposite to the spout is thickened in such a way that it itself forms the handle.

With Schedule tea option, set the time when tea is required. Ocha calculates the time required for your tea and plans it accordingly.


How it works

Once all the inputs are entered, the countdown timer automatically starts. The images below display the working  with the timer countdown along 3 phases.

In case the ingredients are not sufficient to  make the tea, Ocha will notify the user to add the necessary ingredient to proceed.


The magnetic clamps gets activated and it holds the glass bowl eccentrically. Water is boiled using electrode heater within. The process can be terminated at any time by pressing the display button.

Tea bowl starts to spin about its eccentric axis. Preset amount of milk powder gets added to little amount of hot water. Since the pot is being rotated about its eccentric axis, it makes sure that the milk is mixed well with water.

More water will be added as per need keeping the ratio proportionate with milk powder.

The tea holder progresses down into the bowl. It stays down for a preset time according to the choice of decoction while the bowl keeps rotating. Once the tea is ready , it automatically progresses upwards. The temperature of the tea is continuously sensed by the temperature sensor placed  at the bottom of the bowl, and it keeps stirring the tea till it reaches the required temperature. Finally the rotor stops, the magnetic lock gets released and the bowl can be taken out to serve tea.
