I. INTRODUCTION
The widespread use of mobile phones in the world
began in the early 1990s has taken place. In these
years, people started to replace fixed home phones.
Individual phones were welcomed with enthusiasm.
modern mobile phones has a different meaning in
the world. In the increasingly individualized modern
life every person is more liberated with the phone
they have and with this He created a new identity for
himself. The first mobile phones were only speech
and Smartphones that emerged in the 2000s while
allowing messaging by expanding the sphere of
influence of globalization, borders are eliminated.
Managed to remove it. As a milestone in the history
of smartphones in 2007 met with an innovation
described. Apple, led by Steve Jobs It launched the
first iPhone model in history. Apple's iOS operating
system iPhone, which was introduced to the market
with the It brought together the large and touch-
screen iPod and the Internet. The iPhone, which has
the feature of having the first full touch screen,
being a reference point for all smartphones
introduced after it has character. In a short time, the
world like Samsung, Nokia and LG similar calls
have started to come from giants as well [1].
The market share of smartphones, reaching 80% in
the USA and UK, is in Turkey it was 57 percent in
2015 [1, 2].
Intelligent with such a high utilization rate A lot of
research is being done by various analysis
companies regarding phones. This one of the studies
is the European Mobile Analysis company Adjust
on mobile applications. This is the research he
conducted by including Turkey. Another study on
the smart phone usage habits of the Z generation is
in the USA. Made by AppAnnie. Smartphones of 3
different age groups In this study, which aimed to
determine the usage habits of it has been revealed
that the period of time has increased by 40 percent
between 2014 and 2015. Also the same average
number of applications open per day in time period
30 percent, session length increased by around 10
percent. Data consumption has also increased by
around 85% [1, 2].
Access to information for today's people living in
the information age has become easier than ever
with the developing technology. While the rapid
changes in the field of communication technologies
affect individuals socially, culturally and physically,
they create direct or indirect changes in people's
lifestyles. Especially mobile phones emerged with
certain functions in the early 1990s. [2].

Smartphones, which are the new inventions of
humanity, make human life much easier thanks to
their various features. Many important features such
as speech, messaging, internet access, banking,
camera, use of social media, calculator, flashlight,
compass, notepad, e-book reader have made them
very attractive. Now, almost every person has a
smartphone in their hands and these phones are used
extensively [3].
Thanks to these features, it has gained a special
meaning compared to other technological tools. The
smartphone has become a kind of “symbolization as
a reflection of identity and style”. From this context,
it becomes possible to say that today's social reality
is built from codes and software. Numbers, profiles,
symbols, images, digital culture and many other
things can be followed through social networks. The
continuous production of codes and the constant
renewal of the tools that provide this production are
the harbingers of an era in which digitalization
continues to rise. As Bookchin said, while
technology was an extension of humanity, now
humanity has become an extension of technology
[4].
These developments in communication
technologies also improve the capacities of smart
phones and thus the limits of their usage areas [5].
However, this has led to some problems. Because
it causes it to be considered as a need by people and
spends hours on smart phones a day. Fear of not
being able to meet this need or being deprived of the
phone becomes a psychological disorder called
nomophobia when it is excessive in the individual.
This situation, which is also expressed as the
withdrawal symptom dimension of smartphone
addiction; constantly checking the smartphone
without warning, anxiety due to deprivation,
depression, tremor, increase in blood pressure,
feeling of loneliness, increased heart rate, used more
than 7 hours a day, preferring to use the smartphone
despite being asocial, backup battery or charging
behavior without deprivation It can turn into
addiction in situations such as avoidance, using a
smart phone to relieve negative mood, using it in the
classroom, in the bathroom, before sleeping and
while driving. For example, in a study conducted
with 537 university students in Turkey, 42.6% of the
participants were found to be nomophobic. When a
fully charged smartphone battery is used
continuously, one day is usually not enough and
people have to charge their devices frequently. In
solving this problem; It develops technical and
engineering solutions such as creating wireless
charging points, developing energy efficient devices
and applications, and users do not remain silent
against the limited lifetime of their batteries [6].
Phone holder is known as a phone accessory that
has become a necessity in the age of technology.
Like all other phone accessories, the phone holder is
produced to make our lives easier (Fig. 1).
Fig. 1 Phone Holder
The biggest advantage of this accessory is that it
allows you to use your phone comfortably in your
hands-free position. In this way, watching movies
and series on your phone and searching the internet
becomes easier and more enjoyable. You put your
phone on the stand and continue to do other work
while you do. It is a wide range of accessories. For
example; It is not possible to hold the phone in your
hands while washing dishes, eating or preparing
food, before going to sleep, while driving and
working on the computer. In such cases, the phone
holder appears as a hero, a savior. In this way, your
phone remains stationary without moving and
continues to serve its purpose.
II. MATERIALS AND METHOD
In this study, we created the oak phone holder and
power bank unit design using Solidworks 2020
program. Then we analyzed it using Ansys 2021
program. We took the force of the phone as 194 N
and 26.5 degrees to the phone between holder. We
applied its components depending on the angle of
the phone force we received with the axis. We took
the force applied by the power bank unit as 245 N.
Two different analyzes were made, only the force
applied by the phone and the force applied by the
power bank unit together with the phone. Oak was
401
used as material. Material properties of oak is seen
in Fig. 2.

B. Static Analysis
Definition; Static analysis helps development
teams that are under pressure. Quality releases
needed to be delivered on time. Coding and
compliance standards need to be met. And mistakes
are not an option. That’s why development teams
are using static analysis tools. Here, we discuss
static analysis and the benefits of using a static code
analysis tool.
Von Mises Stress; Von Mises Stress criterion is
one of the widely used criteria for designing ductile
material engineering components. To judge if a
design is within design limits and will work safely
for its design life, Von Mises Stress Criteria prove
to be highly effective. Von Mises stress concept is
developed from the distortion energy theory and a
highly preferred failure theory used in the
mechanical design industry.
Shear Stress; Stress resulting from the application
of opposing forces parallel to a cross-sectional area
of a body.
Normal Stress; When the external force acts
perpendicular to the cross-sectional area of any
object or a body, it induces stress in those objects or
a body to regain its original shape. The stress so
produced by the perpendicular action of a force on a
given area is called normal stress.
Maximum Shear Stress; Maximum shear stress
theory is one of the theories of failure used for the
safe design of mechanical components and it is
suitable for a ductile material. The maximum shear
stress theory is also called as Tresca theory of
failure. The method is not suitable in hydrostatic
stress conditions.
Deformation; In engineering mechanics,
deformation is a change in shape due to an applied
force.

IV. CONCLUSION
In this study, obtained the analysis results of the
phone holder and powerbank unit, which designed
with the solidworks 2020 program and analyzed
with the Ansys 2021 program, under maximum and
minimum load. Oak was chosen as the material of
405
the phone holder and powerbank unit for Static
structural Analysis. Because oak wood is a product
with a stylish appearance and a strong strength
value. First, 297 N was applied to the handle part of
the phone holder and seen that the value of the
deformation was very low despite a very large force.
In second analysis, 297 N was applied to the part
where the phone was placed, but 245 N was applied
to the powerbank unit. As you can see in Ansys
analysis reports, deformation is also very small was
obtained. The weight of the telephone and
powerbank units used today is quite low. The phone
holder and power bank unit which is analyzed can
comfortably carry the weight of the phones and
powerbank used today. The phone holder with the
powerbank unit designed as a model can be
manufacture safely.
