The document presents various innovative solutions for problems faced by elderly and disabled individuals, agricultural inefficiencies, and environmental concerns. Key projects include a convertible wheelchair-crutches design for stair navigation, a hybrid agricultural system combining fish farming and poultry, and a fully automated irrigation system. Other inventions aim to improve accessibility for the visually impaired, provide low-cost hearing aids, and develop eco-friendly waste composting methods.

3. PROBLEM REGARDING OLD AGE &
HANDICAPPED PERSONS
• Main problem of handicapped (disabled by legs) and old age persons is their
walking.
• To resolve this we already have wheelchair and crutches but they also have a
limitation i.e. during climbing over staircase they are not comfortable . So
another person required for their help.
• Solution of this problem is to do some kind of arrangement so that they can
walk over stairs also.

4. WHEEL CHAIR CONVERTIBLETO CRUTCHES
• By using some mechanism we can convert wheelchair into crutches so that it
can be used for climbing over stairs also.
• Like by temporary joining it we can make into crutches as well as wheelchair.

5. MODIFIED WALKER
• Walker used by persons can also be modified so that they can be used while
walking over stairs.
• By spring loaded its front legs and they can be adjusted according to the
size of step of stairs.

7. WHYTHIS SYSTEM NEEDSTO BE COME INTO
ACTION
• AT PRESENT FARMERS USETHEIR LAND FOR ONLY ONETYPE OF CULTIVATION
• DUETOTHIS IF ANY NATURAL MISHAPTAKES PLACETHEN HEAVY LOSSES ARE
INCURRED
WHAT NEEDSTO BE DONE
• A SMALL PORTIONOF LAND SHOULD BE DIGTO START FISH Farming.
• ABOVE IT A POULTRY FARM SHOULD BE CONTRUCTED SUCHTHAT FEED RATIO OF HENTO FISH
IS SUFFICIENTTO FEED FISHES.
• NOWWE USETHE OXYGENATEDWATER PUMP and supply this oxiginated water which is rich in
protein directly to the plants.
• The mode of supply would be drip irrigation

8. • ADVANTAGES
• WE ARE ONLY GIVING ONE INPUT AND GETTINGTHREE BENEFITS.
• THERE IS NO NEED OF FERTILIZERS ASWATER WHICH IS SUPPLIED IS RICH
IN MINERALS REQUIRED BY PLANTS.

10. FULLY AUTOMATIC SOLAR GRASS CUTTER
• Having sensor to detect obstacles or to take a
turn.
• Use solar energy.
• Having conveyer belts over wheels so that it
cannot stuck into the pits.

11. PLAYGROUND SWINGSWITH HANDPUMPS
Objective-To draw water from handpumps with the help of
swings.
• Women and children in rural areas often spend a lot of hours
in pumping water for their families.
• In this type of setup as the children play on the swings water
can be pumped simultaneously.The handle of the
handpump is attached to the swing , with the motion of the
swing the handle also works accordingly.
• The setup can be installed near school premises so that the water can be pumped easily.
• Approximately 3 to 5 galoons of water can be pumped in a minute.
• The swing can also operated by a single person.

12. AUTOMATED IRRIGATION SYSTEM
• Automated irrigation system refers to the operation of the system with
no or just a minimum use of manual intervention.
• In this system we can remotely irrigate the fields with the help of wifi
switch and camera.
• As soon as we switch on the button in the mobile ,it gets connected
through the wifi switch and irrigation gets started.
• Camera is used for survelliance purpose to see how much water is required in
the plant and give real time image.
• The images can be seen on the phone .

LOW COST HEARING AID

17. PROBLEM:
Some people have hearing problem and also some old age people
slowly starts to lose their hearing capacity and In rural areas ,hearing
aids are a luxury for the people.
AIM:
To develop the hearing aid at low cost

21. HYBRIDTWOWHEELER
Problems comes in fully electric vehicle:-
Instant charging
Can not increase the route
Speed is not too high
Feature:-
Both wheel drive
Single throttle control
Rechargeable on engine mode
Maximum power at power mode( engine + electric )
 Highly Fuel-efficient
Dual charging mode

22. Advantages over conventionalTwo wheeler:-
Less fuel then traditional counterpart and without recharging
Reduce energy dependence
Environment friendly ( Less Air pollution also Less Noise pollution)
Low maintenance cost
Fuel flexibility
