Design of an automatic car jar
Introduction
One of the most difficult experiences which give many people headache is having their car with
flat tires while moving. There is usually a lot of on people’s their heads when they imagine
getting out and viewing a flat tire (Johnson 2007). Although there is all equipment needed for the
change of tire in the car, the stress of bending and pumping a manual or hydraulic jack become a
bigger stress. Having an automatically operated car jack is a key requirement which will ensure
that when the problem pounces, the major task is to place the jack under the car and then operate
it while standing alongside.
Section 1 - Concept Description
The main concept in this project will be the design of an automatic car jack which can be
operated through Bluetooth. This means that an application on the phone will be used to operate
the jack automatically in lifting and lowering the car. The main idea will ensure the stress of
going under the car and lifting it until the tyre leaves the ground is avoided (Kauffman 2010).
The jack will have a Bluetooth detection device which will ensure it can flow communication
with the phones Bluetooth. Bluetooth is an application which is found on all phones and this will
ensure that users will only have an additional device showing the operation of the jack. The idea
will ensure a new form of car jack, which is automatically operated, is designed. This idea will
be highly operation in hydraulic jacks and not the manual jack systems (Erjavec 2013). The idea
will operate on change the pressures of the hydraulic jack fluids and ensure that they lift up the
cars.

The major value of this project will rely on saving time and energy. The hydraulic jack operates
whereby the oil is sacked into the plunger cylinder. The stress of pumping to lift up the oil in the
hydraulic jack will be omitted (Lewin 2009). This will mean that the time taken to replace the
flat tyres is less than what is being spent now. According to journal by Li, Kim & Jeswiet the
hydraulic jack is able to use the principle of Pascal’s law to operate. It has two mounted
cylinders which have the operating fluid. The design of the automatic hydraulic jack will use the
same principle of Pascal’s law. The already available principle and design is the operated
hydraulic jack. The patents have hydraulic jack which has the same operating valves which will
enhance the operation of the hydraulic fluid in the jacks (Rancourt & Mitri 2011). The hydraulic
has pressure ram cylinder which helps in uplift of the pressure and lowering pressure to lower the
loads. Trye patent has to include critical formulate of the connectivity between the two parts of
the jack and ensure proper lifting of the loads.

Section 2 - Concept analysis
The project will ensure high time saving and cost factor in the long run is achieved. In many
cases, during flat tyres, affected people call for help to solve the project. This is most attributed
to the stress of using the car jack. This new design will have a competitive advantage since it will
require the jack to be placed on the best position and then operated while one is standing outside.
In the long run, the project will achieve cost effectiveness (Rao & Savsani 2012). Moreover, the
project will ensure that the device is operational and enhance the effectiveness in minimizing
challenges achieved with the current car jack design. The design of this project will rely on the
Bluetooth connectivity. The major assumption will be that the Bluetooth connectivity will be
strong enough and not fail during the operation of the jack. In addition, the design will assume
that when the connectivity fails, the jack will not reverse the process and only stops the process.
This will ensure that the jack continues to hold the load imposed. The major weakness of this
project is the relying on the Bluetooth connectivity. In order to address this problem, the project
will have a backup connectivity of the GPRS (Erjavec 2011a). This will ensure in case, GPRS
will be connected when the Bluetooth connectivity fails. Conception design will ensure it
addresses the issue of connectivity.
Section 3 - Skills & Team required
Two major expertise teams will be required in this project. This will include the design team and
also the programming team (Erjavec 2011b). This project will require expertise on design. The
design expertise will ensure that the design on the jack is perfect to ensure proper lifting of the
load. Design team will be able to ensure that the jack fits the perfect design parameters of the
fluid cylinder. The design team will be able to design the best parameters under which the fluid

can be compressed to achieve the required pressure to lift the loads. In addition, programming
skills will be vital in this project. The design team will be important to come up with the best
application programming which will ensure that the application in the carjack can connect with
the gadgets application. The programming skills will ensure that the Bluetooth and GPRS
strength are enough to lift the loads imposed. Proper experience in this will be required to ensure
that the connectivity is able to provide the required strength to lift the loading and not fail
(Erjavec 2010). In addition, the programming team has to ensure that automatic change on the
network is carried out without change on the strength and process. This process will ensure that
the car jack is not destroyed during the change process by the imposed load. These two teams
will ensure that the design and operations of the automatic jack is able to enhance the efficiency
of operation while saving time.
Conclusion
The design of the automatic hydraulic jack will ensure that time is highly saved. In addition, this
project will help come up with proper design to ensure that load increasing load carrying
capacity. In addition, the hydraulic design will factor the changes in the fluid pressure and ensure
it enhances the operation of the hydraulic jack. This project will rely on Bluetooth and GPRS
connectivity. Programming and design will be important experiences which will be applied on
this project.
