ORAL-B BRAUN 5000 ELECTRIC TOOTHBRUSH
INTRODUCTION
The oral-B Braun toothbrush has very appealing features that are helpful in improved
dental hygiene. The toothbrush can be used to clean the sensitive areas in the mouth such as the
gums and the tongue as well as brush all the sides of the tooth and floss the inside sections of the
teeth so as to floss. There are three main modes which a user can choose from out of the 5
specialized modes namely the daily mode, the deep cleaning mode and the sensitive mode. When
the users interact with the toothbrush for the first time, it may cause the teeth to bleed slightly but
in such a situation, a user is advised to load the sensitive mode until they get used to using the
toothbrush. The toothbrush has several parts namely the brush head, SmartScreen that contains
the light indicators, brushing mode display, timer and power charge alert mode. The SmartScreen
is held at the brush handle. The toothbrush is useful in the timely cleaning of teeth and the
toothbrush is very thorough in its cleaning and flossing process.
It is recommended for use by persons who have reduced physical, sensory, and mental abilities.
The user may not have the necessary experience or knowledge and as such may require to have
been given supervision or instruction concerning the use of the appliance in a safe way. This
Toothbrush has an extended feature beyond the electric brushing; it can connect to one’s
smartphone. The connection to the phone requires communication via an application. The radio
transmission is deactivated to avoid occurrence of electromagnetic interference and compatibility
conflicts. The toothbrush allows the user to set the brushing modes according to their preference.
There are a number of brush heads that Oral-B offers that can fit the standard brush handle.
These brush heads are the Cross-Action brush head and the Floss-Action brush heads. These two
are packaged alongside the brush handle and they provide for the total cleansing of the teeth.
The state charts are used to comprehend and describe with finely the system or item behavior.
The diagrams are used for analysis and design. They describe the attributes and behavior of the
application objects. For this case study, the states are the two objects namely the toothbrush and
the Smart phone app known as the SmartScreen. The state charts are used in modelling, a
common practice in engineering designs. The use of state transition diagram is to enable the
visualization of the operation of the real-life system, it specifies the structure and the behavior as
well as providing a template to enable one to understand and implement the system. The state

persists until something external happens usually triggering a transition. A state can persist for an
indefinite period. On the other hand, an event occurs, either instantly or in a limited, finite
period. It is the occurring activity. It is the external occurrence that triggers the transition. An
action is the response of the system during the transition. It is either instantaneous or it requires a
limited, finite period. The state transition diagrams can be represented in different manner based
on the customer’s perception and the system’s perception.
FUNCTIONALITIES OF THE ELECTRIC TOOTHBRUSH
 The toothbrush has a battery unit or charging unit which stores the power for use.
 It has a SmartScreen which allows the toothbrush to connect to the phone App. The
smartphone App can run on iOS or Android Operating Systems. The App guides one
through the entire Bluetooth pairing procedure. The smartphone needs to be in a close
proximity of about 5m distance. It is recommended to place the connecting smartphone
safely in a dry place. The smartphone holder can hold your smartphone while using.
Make sure your phone fits the stand and keeps stable.
 The Bluetooth 4.0 wireless technology is employed to enable connection with the iOS or
Android based smartphone.
 During the setup, the toothbrush is wet and toothpaste is applied on it. The timer is set to
either the professional mode timer or the 2 minutes timer.
 The App is started. It synchronizes with the toothbrush when powered on. It takes some
few seconds to start and then it displays the brush modes and other instructions.
