There are 2 prevalent systems of reclining beds present in India apart from an electric alternative. One involves the caretaker to physically turn a crank situated at the end of the bed near the foot of the person lying on the bed. The other system has notches on the back of the reclining bed which the caretaker has to manually shift and prop it up with the help of a metal rod. The problem with both lie in the fact that they are extremely hard to negotiate with by the patients\patrons themselves. Also combined with the fact that these beds cost a minimum of twenty thousand rupees, while the electric one can set one back by anywhere between thirty to eighty thousand, a cheaper\handier alternative seems very viable considering the Indian perspective.
We have three proposals -
1. With the help of a set of gears incorporated in the working of the reclining bed, the patient can themselves control the extent of recline of the bed by rolling a small wheel, situated on their side at an arms distance, which is attached to the gears. This motion is facilitated by a counterweight extending from underneath the bed, which helps bring the top half of the bed to a semi upright
position. [Fig 1.2 and 1.2]
2. The patient can control the extent of recline of the bed by pressing two buttons, one for either direction, situated on the side of the bed at an arms distance. These buttons will be connected to a handy\cheap car hydraulic jack situated underneath the bed to move the counter weight.
3. This idea is a pure original. Keeping in mind the original counterweight idea, a motor pump [a simple alternating pump] is used to pump water as a weight to and fro from a tank affixed to the bed, to vary the extent of recline of the bed. There will be two buttons again on the side of the bed which would be connected to the pump. [Fig 2.1 and 2.2]
Fig 2.1
The option that turns out to be the most viable after making the prototype and figuring out material and cost will be the decided option to work on.
