Abstract—A one-way travel restriction device is 
proposed. This device can be used on the road to limit 
the one-way traffic of vehicles, avoid retrograde, private 
car parking space will be occupied sometimes, and the 
unsafe factors such as occupying the road at the 
construction site or road in dangerous state. At present, 
the one-way traffic restriction on the road mainly 
depends on the use of traffic police, which is not only 
inefficient, but also wastes a lot of human resources. One 
way travel restriction device can solve the above 
problems. The one-way travel restriction device has 
complete functions and works efficiently, quickly and 
conveniently, which conforms to the requirements of the 
times. So how to meet the needs of modern people in the 
development of intelligence, mechanical and electronic 
information integration of the control operation 
structure provides the possibility of practicality, has a 
very large development value and broad market 
prospects. 
Keywords-One Way; Restricted; Device; Traffic 
I. BACKGROUND OF THE IDEA 
In today's society, with the gradual 
improvement of material living standards, cars 
have been popularized. According to statistics, as 
of May 3, 2020, the number of motor vehicles in 
Xi'an has exceeded 3 million, even 764 circles 
around the city wall, ranking among the top ten in 
China. In recent years, although the traffic road 
has been improving in a good direction, road 
construction is also being implemented, but the 
speed is far less than the growth rate of motor 
vehicles. Traffic safety is also a very important 
issue. Because of traffic jams, small electric 
vehicles and motorcycles are often retrograde on 
the street, which is very dangerous. However, the 
retrograde of small vehicles is not well contained. 
At this stage, a large number of traffic police are 
required to intercept the traffic on the roadside, 
which is undoubtedly very troublesome, Therefore, 
we hope to design a one-way travel restriction 
device. 
II. CONTENTS AND KEY PROBLEMS 
A.  Function description of the project 
The device provides a one-way traffic 
restriction device for vehicles, which can carry out 
traffic restriction management. It solves the 
problem that sometimes private cars will be 
occupied, and when the construction site occupies 
the road or the road is in a dangerous state, the 
danger can be avoided through the one-way traffic 
restriction device of vehicles. 
B.  Current status of the project 
1) Domestic situation 
Domestic common warning signs, road signs, 
road condition reminders, etc. It is used to park 
cars in the garage or parking space, and in case of

emergency. The one-way travel restriction device 
has complete functions and works efficiently, 
quickly and conveniently, which conforms to the 
requirements of the times. So how to meet the 
needs of modern people in the development of 
intelligence, mechanical and electronic 
information integration of the control operation 
structure provides the possibility of practicality, 
has a very large development value and broad 
market prospects. 
2) Current situation abroad 
Nowadays, many foreign countries adopt one-
way traffic, but in China, because of the large 
number of vehicles and people, two-way traffic is 
adopted. 
Foreign single traffic can be divided into three 
types. The first is Manhattan style: long distance, 
wide range regional one-way traffic mode. The 
second is the London model, which is mainly 
based on the one-way road within the plot. The 
third mode is Singapore mode: the combination of 
trunk road and branch road. 
C.  The key problems to be solved in realizing the 
function of the project 
Key problem 1: there will be vehicle retrograde 
phenomenon: I think the project can play a good 
role in one-way traffic restriction. We think that 
solving the retrograde problem has always been a 
problem. This device can change the retrograde 
problem from telling people "can't do" to "can't 
do". The problem of mandatory change. 
Key problem 2: unidirectional device can also 
be used in other aspects. Such as construction 
restrictions, parking lot entrance, crossroads and 
other places. It can solve the problem of hidden 
danger caused by nonstandard driving to a great 
extent. 
III. SPECIFIC SCHEME OF PROJECT 
IMPLEMENTATION  
A.  Preliminary planning 
At first, we put forward three plans 
One is through the transformation of 
parallelogram mechanism. When the bevel of a 
parallelogram is tilted, the height of its upper and 
lower sides will decrease. When the parallelogram 
is vertical, the height of the upper and lower sides 
is the maximum. Based on this, when the left and 
right sides of the quadrilateral tilt, the height can 
not make the vehicle pass, but the vertical height 
can pass. According to this principle, the model is 
put forward. The change of controlling 
parallelogram mechanism is through the thrust 
force of bar pair and mechanism. Using the lever 
principle, when there is no vehicle passing on one 
side, the parallelogram mechanism is in a non 
rectangular state because there is no force on one 
side of the lever, and the height is not enough to 
make the vehicle pass. When a vehicle passes by, 
one end of the lever is pressed down and the other 
end is lifted up. The action of the connecting rod 
receiving the force and the specific trajectory of 
the given plane makes the parallelogram receive 
the right force, the parallelogram deforms into a 
rectangular state, the height becomes higher, and 
the vehicle can pass through. If you go retrograde, 
you can't get through because there is no lever. 
This scheme can realize the original expectation 
and can be made into a single line device. 
However, compared with other schemes, this 
scheme has the following problems: compared 
with other schemes, the mechanism is too complex 
and inefficient, which may restrict some higher 
vehicles from passing through, and there are too 
many restrictions, so it is not adopted. 
The second scheme: when the vehicle passes 
through the unidirectional driving device from the 
reverse direction, the pressure block above the 
device is pressed down by the wheel, the spring is 
compressed due to the gravity action of the vehicle, 
the rod connected with the pressure block is 
lowered, and the middle of the rod is connected 
with the frame through the low pair hinge. 
Therefore, the other end of the rod will be lifted, 
and the baffle connected with the rod through the 
hinge will also be lifted, So as to restrict the 
passing of vehicles. The other end is provided with 
the same rod assembly. When the vehicle is 
passing in the positive direction, the lifting of the 
rod will make the baffle lower, so the vehicle can 
pass through.

The third scheme: a varistor is set on one side 
of the road to connect with the gear lever. When 
the car is passing in the positive direction, the 
resistance of the varistor decreases due to the 
increase of pressure, and the gear lever rises, and 
the car passes. The reverse vehicle cannot lift the 
lever through the varistor. 
B.  Determination of final scheme 
After discussion, we think that the structure of 
scheme 1 is more complex, and there are great 
limitations for the height of the vehicle. However, 
there is no specific implementation agency to 
explain his plan. Finally, it was decided to use 
scheme 2. 
IV. SCHEME DESCRIPTION 
The device provides a one-way traffic 
restriction device for vehicles, which can carry out 
traffic restriction management. It solves the 
problem that sometimes private cars will be 
occupied, and when the construction site occupies 
the road or the road is in a dangerous state, the 
danger can be avoided through the one-way traffic 
restriction device of vehicles.

Figure 1. Schematic diagram of the device 
 
Figure 2. Schematic diagram of the device (main view) 
As shown in Figure 1 and Figure 2, the 
following conclusions can be obtained:the product 
comprises upward convex pressing blocks 12 and 
13, which are respectively connected with the 
support plate 1 and the support plate 11 through 
springs. The support plates 1, 2, 10 and 11 are 
rigidly connected with the shell, and are fixed in 
the axial direction and transverse direction. The 
connection among the rods 3, 4, 5, 6, 7, 8 and 9 is 
hinge connection. Among them, shaft 14, shaft 15 
and shell are rigidly connected. When the vehicle 
enters the device from the right side, the gravity of 
the vehicle causes the pressure block 13 to move 
down, and the shaft 3 to move down makes the rod 
4 rotate clockwise around the shaft 14, so that the 
rod 5 moves up, the rod 7 moves down, and the 
rod 6 rotates counterclockwise, and the vehicle can 
pass through. When the vehicle enters the device 
from the left side, the gravity of the vehicle causes 
the pressure block 12 to move down, the rod 9 to 
move down causes the rod 8 to rotate 
anticlockwise, thus the rod 7 to move up, and the 
rod 6 to rotate clockwise, so the vehicle cannot 
pass. 
 
Figure 3. Structure diagram of the device 
According to Figure 3, we can know that is the 
structure diagram of the device. It can be seen 
from the structure diagram that the main principle 
of the device is the lever principle. Lever principle 
is also called "lever balance condition". In order to 
balance the lever, the two moments (the product of 
force and arm) acting on the lever must be equal. 
That is: power × Power arm = resistance × The 
resistance arm is expressed as F1 · L1 = F2 · L2.

Where F1 is power, L1 is power arm, F2 is 
resistance and L2 is resistance arm. 
 F1 × L1 = F2 × L2 
Through (1), we can get the following 
conclusion: when the right side of the bar moves 
downward under pressure, the left side of the bar 
will lift up to form a small slope, which can make 
the vehicle pass. But the gravity of the car can't act 
on the left bar directly, so it can't pass from the left. 
It can be seen from the above formula that in order 
to balance the lever, the power arm is several 
times of the resistance arm, and the power is a 
fraction of the resistance. 
When the vehicle passes through the 
unidirectional driving device from the reverse 
direction, the pressure block above the device is 
pressed down by the wheel, the spring is 
compressed due to the gravity action of the vehicle, 
the rod connected with the pressure block is 
lowered, and the middle of the rod is connected 
with the frame through the low pair hinge. 
Therefore, the other end of the rod will be lifted, 
and the baffle connected with the rod through the 
hinge will also be lifted, So as to restrict the 
passing of vehicles. The other end is provided with 
the same rod assembly. When the vehicle is 
passing in the positive direction, the lifting of the 
rod will make the baffle lower, so the vehicle can 
pass through. 
 
Figure 4. Appearance of one way travel restriction device 
As shown in Figure 4 is the appearance of one 
way travel restriction device. We designed the 
appearance of the device like this, referring to the 
appearance of the speed bump on the highway. 
This device can be more convenient to install on 
the road, at the same time, the device can also play 
the role of deceleration belt, can replace the 
deceleration belt, to achieve double effect. 
V. MARKET RESEARCH AND COMPETITION 
ANALYSIS 
A.  Market Research and analysis 
Domestic common warning signs, road signs, 
road condition reminders, etc. It is used to park 
cars in the garage or parking space, and in case of 
emergency. The one-way travel restriction device 
has complete functions and works efficiently, 
quickly and conveniently, which conforms to the 
requirements of the times. So how to meet the 
needs of modern people in the development of 
intelligence, mechanical and electronic 
information integration of the control operation 
structure provides the possibility of practicality, 
has a very large development value and broad 
market prospects. 
B.  Competition analysis 
PEST analysis is the analysis of macro 
environment. Macro environment, also known as 
general environment, refers to the main social 
forces that bring opportunities or threats to 
enterprises. They directly or indirectly affect the 
strategic management of enterprises. An important 
tool to analyze the macro environment is PEST 
analysis model, which analyzes the impact of 
environmental changes on enterprises from the 
political, economic, social and technological 
perspectives. 
Politics: in 2006, the outline of the national 
medium and long term science and technology 
development plan (2006-2020) was published, and 
the 18th National Congress of the Communist 
Party of China made the strategic deployment of 
innovation driven development. In 2015, the 
opinions of the CPC Central Committee and the 
State Council on deepening the reform of system 
and mechanism and accelerating the 
implementation of innovation driven development 
strategy were published, In the same year, the 
implementation plan for deepening the reform of 
science and technology system was also issued. 
Economy: closely linked to development. We 
should adhere to problem orientation, face the 
International Journal of Advanced Network, Monitoring and Controls      Volume 06, No.03, 2021 
70 
forefront of world science and technology, face the 
major national needs, and face the main battlefield 
of the national economy, clarify the main direction 
of China's innovation and development, make 
breakthroughs in key areas as soon as possible, 
and strive to form more competitive advantages. 
Deepen reform. We should keep pace with the 
reform of the science and technology system and 
the reform of the economic and social fields, 
strengthen the connection between science and 
technology and the economy, follow the laws of 
the socialist market economy and science and 
technology innovation, get rid of all ideological 
barriers and institutional barriers that restrict 
innovation, and build a good environment that 
supports innovation driven development. 
Strengthen incentives. The essence of 
innovation driven is talent driven. We should put 
people first, respect the value of innovation and 
creation, stimulate the enthusiasm and creativity of 
all kinds of talents, and speed up the gathering of a 
large-scale, reasonable structure and high-quality 
innovative talent team. 
Open wider to the outside world. We should 
persist in planning and promoting innovation from 
a global perspective, make the best use of global 
innovation resources, comprehensively enhance 
China's position in the global innovation pattern, 
and strive to become a leader in several important 
fields and a participant in important rule making. 
Society: develop smart city and digital social 
technology, and promote the people-oriented new 
urbanization. Rely on new technology and 
management innovation to support new 
urbanization, modern urban development and 
public services, innovate social governance 
methods and means, accelerate the informatization 
process of comprehensive governance of social 
security, and promote the construction of a safe 
China. Develop standardized, digital and 
intelligent technologies for municipal 
infrastructure such as transportation, electric 
power, communication and underground pipe 
network, and promote the large-scale application 
of key technologies in green building, smart city, 
ecological city and other fields. We will strengthen 
key technologies and products in major disaster 
and public security emergency areas. 
Technology: China's innovation driven 
development has the foundation to accelerate. 
After years of efforts, the development of science 
and technology is entering a leap period from 
quantitative growth to qualitative improvement, 
the scientific research system is increasingly 
complete, the talent team is growing, and the 
independent innovation ability of science, 
technology, engineering and industry is rapidly 
improving. Economic transformation and 
upgrading, continuous improvement of people's 
livelihood and national defense modernization put 
forward a huge demand for innovation. The 
combination of huge market scale, complete 
industrial system, diversified consumer demand 
and the improvement of innovation efficiency in 
the Internet era provides a broad space for 
innovation. The system of socialism with Chinese 
characteristics can effectively combine the 
advantages of concentrating on major affairs and 
market allocation of resources, which provides a 
fundamental guarantee for innovation driven 
development. 
VI. CONCLUSIONS  
The device provides a one-way traffic 
restriction device for vehicles, which can carry out 
traffic restriction management. It solves the 
problem that sometimes private cars will be 
occupied, and when the construction site occupies 
the road or the road is in a dangerous state, the 
danger can be avoided through the one-way traffic 
restriction device of vehicles. The utility model 
relates to a one-way limiting device used for 
private parking space management, which can 
control the movement of the support plate through 
a simple structural design, drive the rod to move 
up and down, and then control the rotation of the 
panel, so as to achieve the purpose of one-way 
limiting. The one-way limiting device of the utility 
model can be used for the use and management of 
private parking space, Prevent private cars from 
going in and out in opposite directions, causing 
congestion.

Is orthodontics really a health profession?
(Aust Orthod J 2021; 37: 360 - 361. DOI: 10.21307/aoj-2021.041)
 It is commonly stated that the benefits of orthodontic 
treatment are the restoration of function and an 
improvement in aesthetics. Most would agree that 
the stability of a treatment outcome is a holy grail 
and attempts to tie teeth down using either fixed 
or removable retainers only defers the inevitability 
of change. Arguably, dental aesthetics is improved 
in all but the most-fussy patient but there may be a 
compromise in facial aesthetics unless an underlying 
mismatched skeleton is corrected. Even then, there 
is no guarantee that the repositioning of hard tissue 
parts will provide the appropriate foundation for soft 
tissue behaviour, aesthetics or long-term stability.
The altruistic view of several decades ago was that 
occlusal function was enhanced by orthodontic 
treatment. The restoration of a balanced Class I 
relationship without excursive interferences would 
improve mastication and maintain TMJ health. 
Substantial research in the 1990s has indicated that 
orthodontic treatment neither causes nor corrects 
TMJ disturbances and so the functional argument 
loses a level of credibility. Patients have no reference 
by which they might measure masticatory efficiency 
and learn to cope with occlusal disharmony.
An often-quoted reason for orthodontic treatment 
is the promise of improved oral hygiene. The 
straightening of irregular teeth is considered to render 
oral hygiene practices, of plaque and debris removal, 
easier for the patient. However, the patient needs the 
motivation to perform, and continue to regularly 
perform and apply, appropriate cleaning protocols 
throughout life. Dentistry is currently in the world of 
‘do-it-yourself ’ orthodontics, which is unfathomable 
when DIY oral hygiene is so difficult to achieve in the 
gnarly teenager. How many clear aligner programs 
have failed due to waning compliance and adherence? 
How many fixed appliance cases have failed due 
to the inability of patients to follow instructions? 
Why are miniscrews so popular in contemporary 
orthodontics? After all, orthodontics was conducted 
to a high level of precision and outcome during the 
last century.
What does a patient expect from orthodontic 
treatment? Consistently, the chief patient complaint 
is ‘I don’t like my crooked teeth and would you to 
straighten them please’. Are patients concerned 
about their occlusal articulation and interdigitation? 
Patients and their parents are regularly concerned 
about excessive tooth displacements or a large overjet 
and seek treatment to retract upper incisors to improve 
aesthetics and reduce the risk of traumatic damage. 
The fact that the lower incisors and chin might be 
recessive is seldom appreciated and so the value of a 
clinical visit is to examine the patient, diagnose the 
problem(s) and recommend an appropriate treatment 
approach.
In simply straightening anterior teeth, has ortho-
dontics degenerated to the level of the cosmetic 
industry? A beauty parlour serves a purpose of 
making people feel good about themselves after an 
aesthetically enhancing procedure. Those procedures 
are usually temporary and need to be periodically 
repeated to maintain a client’s psychological health. 
Therefore, is it appropriate and acceptable that the 
mental wellbeing of a patient is the major health 
benefit of orthodontic treatment and that periodontal 
and occlusal health are goals that might be lauded 
but not necessarily permanently achievable?
Nature and aging and the inevitable failure to 
maintain a treatment outcome in the long term will 
result in a decline or loss of smile aesthetics. The success 
of orthodontic treatment is invariably measured by 
the satisfaction and happiness of the patient related 
to tooth alignment rather than an improvement in 
their stomatognathic function. Unlike medicine with 
its healing philosophy, dentistry and orthodontics

seldom heal but simply camouflage problems which, 
despite earnest attempts, re-appear at a later time and 
in a following generation. Orthodontists, through 
their training, are knowledgeable in human growth 
and development, gnathology and tissue systems but 
can orthodontics really continue to classify itself as a 
health profession if our services are not sustainable. 
Many consider orthodontists to be oral beauticians 
who provide some uplifting moments before the rea-
lity of change, strikes. What do you think?
