The OrthoCAD team has developed a modular rotating‐hinge total knee prosthesis suitable for Indian population, and evolved a manufacturing route to achieve high quality and economy. The prosthesis components are available in a range of sizes, which
can be inter‐changed to match the anatomy of a particular patient. The design has been validated by an integrated approach combining computer aided analysis, rapid prototyping, and knee simulators. The manufacturing route combines rapid pattern
fabrication, investment casting, CNC machining and super‐finishing to achieve high geometric fidelity, smooth finish, and superior properties. Innovative instruments, such as femoral jig and tibial jig have been developed to ensure ease, speed and accuracy
of prosthesis implantation. A 3D surgery planning software ensures correct part selection and accurate implantation. Several major hospitals in India have come forward for the clinical trials of the prosthesis.

This project is aimed at designing a pump based water filter bottle for CRPF Jawans which is lightweight, durable, soundproof, easy to carry, use, maintain and has a capacity of storing 1 to 2 liters of water.
CRPF Jawan will keep the bottle inside pocket of the bag. When he reaches the contaminated water source, he takes out the bottle from the bag. He opens the base cap, takes out the filter which is attached to the pump with the help of pipe and throws it into the water source. He then hand cranks to pump in clean water into the water bottle. After pumping, he takes out the filter from a water source, wind up the pipe and put it back into base cap. He snaps the base cap to the bottle. He, then opens the drinking cap and drinks potable water from the bottle.
1) The device has a built-in pumping system for ease of drawing and filtering water.
2) There is a storage provision for the filtered water after pumping.
3) Use of HDPE makes the bottle durable as HDPE is safest form of plastic to be used as it is very hard wearing, does not breakdown under exposure to extreme weather conditions.
4) The filter housing is integrated with the bottle.
5) Hand cranking is preferable and more advantageous to suction for obtaining filtered water.

DIC team visited Akhop, Ramgarh and Sripalpur villages in Balia district of Uttar Pradesh. Arsenic in shallow aquifers is a major groundwater problem in the district. During four days visit, the team interacted with the villagers and tested the domestic arsenic filter designed in Design Innovation Center.
On 13th May 2017, DIC team along with Water group member Mr. Ravindra visited two villages Biturli and Kawanai near Igatpuri, Nashik. The water cart was given for testing to the people during the first week of April. The team, during the visit got feedback and also found few issues to be resolved. The people are demanding for more number of carts to be given to them for use and are also ready to purchase it.
Arsenic poisoning due to underground water is a big health concern in India, especially in the states of Uttar Pradesh, Bihar, Jharkhand, West Bengal, Assam and Manipur. The main objective of this project is to develop an Arsenic water filter for domestic use which filters water for a household without using power supply. The main challenge in this project was to make a product which will remove arsenic contamination from water and will actually be used by the people living in the affected regions. Form Factor, use of indigenous raw materials, low-cost, durability, easy to use, maintain, cleaning and aesthetic design are the main considering factors for design. The Water filter designed by Vishal Bhushan Jha, brings this technology to the individual users.
