This document summarizes a student seminar presentation on designing a solar-powered wheelchair for disabled or handicapped individuals. The presentation covers introducing the current non-powered wheelchair system, the objectives of developing a solar-powered model including generating renewable energy and allowing longer distance travel. It also includes diagrams of the proposed gear mechanism and statistical analysis of lift energy usage. The conclusion restates that the aim is to develop an affordable system that generates power from the sun to enable independent mobility.

3. IntroductionIntroduction
 In this project solar panel generates electricity.
Disable or Handicap person can able to use this system
anywhere on their workplace.
 this project can be useful for old persons and physically
weak persons also person who injured from accident.
 The present world the medical field is very much focuses
about to care the patients, and the patient/ handicapped one
are like to leave individually without the help of any others
so, this proposed product will be very effective for the
them.

4. AimAim
 Redesigning the existing system.
 To generate the energy from existing system and utilised
variously mainly when the power cuts.

5. Objective of SystemObjective of System
 Analysis of present system.
 To develop a vehicle that use renewable energy,
environmentally friendly and cheap.
 To develop an electrical tricycle that can charge the
battery when it is not in used.
To develop low speed, but for a longer distance.

6. Current systemCurrent system
 In the current system, there is only use of lift is to lift
from down to up and vise versa. These mechanical motion
is unutilized.
 The current system does not have any mechanism to
utilized the power generated by the lift motion.

7. Basic Diagram of Building LiftBasic Diagram of Building Lift

8. Problem DefinitionProblem Definition
 In the present system there is not any arrangement to
utilized the mechanical energy for power generation.
 The energy produced in existing process is not define.

9. Proposed SystemProposed System
The invention and the preferred modes of use will best be
understood by reference to the following detailed
description of an illustrative embodiment. A control block
diagram of a self generating elevator emergency power
source for an elevator system using a reciprocating and an
electrical generator. A control block diagram of self
generating elevator emergency power source for an elevator
system using a reciprocating and an elevator motor in
generator mode.

11. StatisticalStatistical AnalysisAnalysis
 Energy = Total work of lift system + Total standby losses
Total work of the lift system = ∑ (no. of trips by lift *
distance travelled per by lift)
Total work of the lift system=a * Σ (distance travelled per
trip per lift)
Total work of the lift system= a * Lift Floors
Total standby losses = b * NLA
Annual Lift Energy (kWh) = 528 * Lift Floors + 5.47 *
occupied NLA (m²)

12. AdvantagesAdvantages
 Generate the power from lift and use these for various
things (i.e fan, lights) in no cost.
 When the power cuts the energy saves in the battery will
utilized.
 The assembly is very easy and cheaper in rate so power
generation rate is low.
 Maintenance cost of the project is also low.

13. ConclusionConclusion
Various modifications of the disclosed embodiments as well
as alternative embodiments of the invention will become
apparent to persons skilled in the art upon reference to the
description of the invention. It is therefore contemplated that
the appended claims will cover any such modifications or
embodiments that fall within the true scope of the invention.
