Vertical Axis Windmill

Sat, 23 Aug 2008 11:35:16 +0530

Instant invention is useful at low wind power as well as high wind power, as it Compresses received wind & Increases velocity by 32%. Due to it’s circular design, whenever wind blows from any direction wind gets compressed and then diverted towards wind receiving side (only positive). Also Vertical Plates protect the convex side of rotor blade from negative wind and same wind diverts towards wind receiving side. Resultant it generates heavy torque at rotor shaft.

Gear System for Cycle Rickshaw

Mon, 20 Aug 2007 16:25:39 +0530

Rickshaw pulling is an exhausting task especially on an uphill track when the power that the pedals can transmits, falls short of the critical level. The rider has to get off and physically pull the rolling load at a drain rate of energy. Jabbarbhai’s variable gear system consists of the plurality of the sprocket mounted on a pair of shaft. Free wheels are provided on the front and rear shaft of the gear system. The free wheel can provide free movement in the clockwise and anticlockwise direction. The free wheel comprises of a dog lifter, instead of a spring loaded dog pawl.Hence require l

Auto Compression Sprayer

Tue, 21 Aug 2007 12:30:31 +0530

The sprayer utilizes the ergonomic jerk experienced by a person while walking to generate pressure which operates the sprayer. The spring and dead weight act as an actuator for generating pressure inside the pump and thus spraying is done without any manual strokes required for operation. There is tremendous savings in manual energy while spraying due to which the productivity of spraying increases.

The innovator of the Auto Compression sprayer is Sh. Arvindbhai Patel, who is a serial innovator. He has invented many other devices like the Natural Water Cooler and Auto Air Kick Pump. He has studied up to Class Xth and had enrolled for an ITI Course, but he dropped out midway. Arvindbhai has also worked for about 5 years as a mechanic in a petrol pump

Buttonhole Edging Machine

Tue, 21 Aug 2007 17:12:51 +0530

The innovative buttonhole machine developed Mr. Anil Kamdar is machine ideally suited for the Indian environment, especially the rural and the semi-urban markets, where availability and parts and maintenance is an issue. Second hand imported machine are used for buttonholing by tailors in large cities. However, the same machine cannot be used in smaller towns and villages because these machines are complex and can be repaired only by the company trained and authorized service stations, which are located only in the large cities. The innovative buttonhole machine is so designed that most average sewing machine

Double Acting Reciprocating Pump

Sat, 22 Jul 2006 20:31:00 +0530

In the monsoon-dependent Indian scenario, equipment for lifting water from the ground plays an important role in farming. As farmers face acute water scarcity due to the falling water table, accessing under ground water through an efficient reliable pump has become imperative. Having had first hand experience both in farming and in motor rewinding, Manubha knew that drawing groundwater by using submersible pumps was an unreliable and expensive preposition. Finally he has developed an innovative double acting reciprocating pump.
This innovation comprises a water-lifting pump adapted to be operated by means of a prime mover through a balancing mechanism. It can be mainly classified as having two parts i.e. a pumping unit and a lifting mechanism. The pumping unit consists of the piston,cylinder (Bi-housing body), valves, oil seal, sleeve, compression ring, piston rod and suction and discharge pipes. The pump works on the principle of reciprocation of the piston and the cylinder. Creation of vacuum resulting in suction and compressing of the water resulting in discharge is the basic principle of operation. Each cycle consists of two strokes. Both the strokes are effective and hence it is known as a Double Acting Reciprocating Pump. The lifting mechanism consists of the crank, coupler, walking beam and connecting rod. Prime mover (electric power or diesel engine), belt and pulley, revolute joints and bearings are also the accessories of the mechanism. The mechanism works on the principle of four-bar linkage mechanism having single degrees of freedom and there is a provision of balancing the load in the mechanism.
Using two chambers in the cylinder as well as a creative arrangement of valves, double acting is achieved. This water lifting pump can be installed in the well bore or any other suitable water source simply by increasing the length of the piston rod of the pump. Manubha has also developed an idea of balancing mechanism in this pump. In the conventional pump, weight of the piston rod remains unbalanced and so during upstroke, the lifting mechanism needs to carry the extra load of the piston rod. However during the down stroke the piston rod reduces the required workload. But, due to this, the total system suffers from an unbalanced load distribution throughout the cycle. By introducing the balancing mechanism, the innovator has introduced a system, where throughout the cycle, the load is uniformly distributed. Adjusting the weight of the balancing mechanism enables the smooth operation of the pump.

Small Diesel Engine

Tue, 21 Aug 2007 11:38:52 +0530

The innovator has developed a unique, lightweight and compact 3.5 HP, single cylinder, 4-stroke diesel engine with many significant facets. It is compact, portable, powerful, lightweight and affordable diesel engine with varied applications. The engine was mounted on a Rajdoot motorcycle, which achieved an average speed of 55 km per hour and fuel consumption of 100 km per liter.

The innovator of the small efficient diesel engine, Shri Mansukhbhai Suthar, is an illiterate (he has studied only till class 2) mechanic genius in engine technology. He has experience of about 40 years in repairs of all kinds of engines.

Aaruni Tilting Bullock Cart

Mon, 22 Oct 2007 12:25:44 +0530

In the traditional bullock cart, with two wheels, part of the load is borne by the draft animals on their shoulders and neck and the harnessing system at present makes it difficult to negotiate sharp bends or turns in the road. This causes the gals on the neck of the bullocks, which affects not only the efficiency of the animals but also their stamina. This cart is thus designed to overcome the shortcomings of the traditional carts by having an additional wheel to balance the load. In addition the cart has a tilting mechanism which is based on the rope and pulley system which can be controlled by a lever located alongside the cart driver.
