INTRODUTION Everyone is talking about modern vehicles
with automatic gears and gear shifters today, but it is out of the reach for most of us.
What makes this utility so expensive????? Can it be made accessible to the common
man????? Can the traditional manual gear shifters be
modified effectively to Automatic????? We believe it is possible, And we’ll
demonstrate it now!

OBJECTIVES1) To create a effective and viable design for
an modern gear shifting mechanism.2) To create a innovative and reliable design3) To make it as ergonomic as possible.4) To achieve a cost effective and easily
marketable product.

SCOPE, MERITS AND USES Can easily replace all conventional gear
shifting mechanism with slight modifications It can achieve reliable and instantaneous
shifting of gears. It is simpler and cheaper than hydraulic or
mechanical actuating mechanisms. Can be easily adapted to any applications. Can be used in all kinds of vehicles

BASIC PRINCIPLE A gear box consists of a set of meshing gear
pairs which transmits motion from the prime mover to the driven element (eg. An engine to the tires of a car ).
It can do so with variable speed and torque by changing the active gear pairs which are meshed together.
Shifting from one gear pair to another is achieved by a mechanism which can be atuated by a number of ways.
We will actuate the mechanism using electromagnetic forces, thus creating an electrically operated gearbox.

WHY AN ELECTRICAL MECHANISM Using an electromagnetic actuation
mechanism makes the system very reliable as it reduces the no. of moving parts.
The actuation time is drastically reduced thus the lag in between shifting between two gears is also reduced giving precise and easily operable gear shifting.
The electrical circuits and the electromagnetic mechanism is cheaper, more reliable and simpler than conventional mechanisms(eg. Hydraulic, Lever, or linkage system)

WHAT WE ARE DOING We created a concept design for an
electromagnetically actuated gear box. We made a working model for our concept
design. We proved that we can operate a functional
gear box through our design We created a very user friendly, simple and
reliable gear shifting control system. We tested it for efficiency and performance.

CONSTRUCTION OF THE ELECTROMAGNET
•We know that when a current is passed through a conductor a magnetic field is set up around the conductor.
•If a sufficient amount of current can be passed through the conductor it can be used to induce magnetism in a metallic object.
•Thus we can create very strong magnets using the above principle

CHALLENGES WE MAY FACE1. Designing a functional gear box or variable
speed and torque.2. Designing a actuation mechanism for the
gear box.3. Creating a live working model.4. Choosing the right type of gears.5. Constructing an electromagnet with
sufficient power.6. Designing the electrical circuits for
operating the mechanism.

WHAT WE WILL ACHIEVE We obtained a rich experience and
knowledge of the working and construction of a gear box.
We created our own gear box with variable speed and torque capabilities.
We actuated it using basic scientific and engineering principles
We successfully demonstrated our concept for an automatic gear shifting mechanism through a working model.

FUTURE SCOPE We believe that this is only the beginning of
many more innovative ideas for replacing traditional actuation systems.
These gear shifting mechanisms can be employed in any vehicle.
It has the potential to become a standard feature in all kinds of vehicles at an affordable price for all sorts of customers.
The actuation system can be employed in other applications as well.
