In rural India bad roads are a very common sight. Due to these bad road conditions poor farmers lose their little money to maintain these tyres which wear out faster and have frequent punctures. All the potholes or bumps on the road reduces vehicle speed and increase fuel consumption which is again a big expense for poor farmers, and poor travel conditions affect their health conditions too.
So the idea of reinventing the wheel for a new cause was important using basic physics. The wheel design is intuitively and simple. It has a 6 segments of triangle rubber blocks which has a gap in the centre concentric to the outer shape. These segments are mounted on a hexagonal hub. The segments are placed tangentially to the hub to produce maximum torque while in motion. Its unique placement of segments on the hub also helps with generating extra momentum when the wheel goes over a rock or obstacle. The segment deformed due to the rock or obstacle pushes the next segment which in turn pushes the next. Once the pushing action is passed through all the segment the last segment, one before the deformed segment which generate a traction on the ground surface to create extra momentum.
The benefit of this design is there is no pneumatic tyres, hence no puncture problems. If a portion of the wheel is worn out the whole tyre need not be required to change so its economical. The design of the tyre allows to absorb 70% of the road shocks, therefore more comfort on bad roads. The Tyre do not lose momentum due to obstacles or bad road so no loss in fuel economy.
The vehicle could also be use for various other purpose such as offroading and rovers for space missions.
