The mode of transport People often choose diďŹ&#x20AC;erent means of transport to go out.

32%

Cycling is not just a form of transportation but a common sport. This is a healthy way.

Take bus ride The bus or subway has become a means of transport that most people choose when they go out. This is very convenient and convenient.

In China, people's homes are usually far away from the company or school, so this is not the most common form of transportation.

BUS

And going out by bike can take a lot of time. BICYCLE

With the improvement of urban construction, the public transport system covers most parts of the city. The number of people traveling by bus and subway is very average, as both bus and subway have their own comfort.

30% Modern social means of transport are very convenient, and people can choose many transportation methods.

According to incomplete statistics, most families in China have their own car. Therefore, the usage rate of the car is relatively high.

SUBWAY

But most young people do not have their own car. Most of them live their own lives and do not live at home. So you are more used to public transport.

According to the survey, 30% of respondents opt for the subway and 32% for the bus. 20% drive by car and 10% by taxi. 6% of the walking people went out and 2% of the cyclists.

6% on foot

Some people walk to work or to school. This situation is relatively rare, usually because their home is near the school or the company. Walking to work or going to school is often considered a healthy way.

Taking a taxi is a very convenient way to get around. The downside is that it costs more.

STUDY / WORK The life of the students is very regular. They usually have a longer study time per day. In China, study times, rest periods and students' exercise time at the school are very regular. Due to intensive learning, the school organizes 2 to 3 hours of exercise daily to ensure good health. Many students live in or are close to the school, so they spend less time along the way.

Many Chinese oďŹ&#x192;ce workers are now under great pressure. They work more than 9 hours a day. Constant overtime withdrawal of their free time and even overtime on weekends. Intensive work leads to lack of rest and movement. Health problems due to lack of exercise are increasingly taken seriously. Many young people live in very cheap homes when they start working, but they are a long way from the company. As a result, they spend a lot of time each day on the way.

When people come into middle age, their careers have a certain success and the money has gradually become more generous. Therefore, they are more willing to spend time on health management. At the same time, it also began to balance working hours and rest periods. Only a few middle-aged people will work hard day and night. Another reason is that your body is having some problems, so you need to look after your health.

The elders are not working anymore. You spend more time with life and peace. At the same time, non-intensive training is also good for the body. So you train regularly and more than most young people. Because of their attention, they are becoming healthier and even more so than many young people. But that is also because older people have a lot of time.

POSSIBILITY We can use this waiting period to remind people how to exercise. We provide information, People need, for example, the time the bus arrives at the station. But people have to pay some movement.

Full body exercise Here are three ﬁtness machines that allow people to move throughout the body.

Indoor Cycling

the crosstrainer

After indoor cycling overcame all the shortcomings of outdoor riding, the sport became a simple aerobic exercise that can train the entire body due to the technical improvement.

The crosstrainer is a fairly common training tool for cardio-pulmonary training and is also frequently used by users.

the rowing machine The steering machine has a good eﬀect on the muscle strengthening of the legs, waist, upper limbs, chest and back. Each time, the upper limbs, abdomen and back undergo a complete contraction and extension, allowing for an aerobic exercise eﬀect on the whole body muscle.

* I simulate the foot pedal power generator by turning the generator by hand.

The rotation of the gear generates kinetic energy. Kinetic energy is converted into electrical energy. This starts the power supply and starts the operation of the device. After switching on, the LED on the fan side lights up.

The gears rotated to turn the fan blades in rotation.

I started 3d hologram LED FAN in two ways. One is power-driven power generation to produce LED light, one is the gear to set it in rotation.

This starts the 3d holographic advertisement. The principle is: The fan side rotates when the LED on the fan side lights up so users can see the projected image. So I use gear to spin it. When the user is using, step on the pedal. The pedal rotation drives the gears to rotate.

PLAN C The appearance is sportier. The user looks at the projection.

PLAN A

It improved idea2. Its gears are exposed and eye-catching. It can also be wrapped in a transparent case.

PLAN B

The shape is sporty and resembles common sports equipment.

The base is heavy and the gear structure is wrapped. The gear connection is very long. In use, the user directs his back as in a normal sitting.

Model 1 gear transmission The gears are connected at the top with the projector and the gears are turned to rotate the projector. Gear transmission is very stable and has a moderate speed. Gear transmission structure in this construction is suitable as power transmission. But this model is not ergonomic. The size is not suitable for human use. When the human model is used, the buttocks have no contact with the seat. At the same time the seating area is too low so that the foot can not step on the pedal. The hand can not hold the handrail.

Is there an easier way to connect?

Model 2 belt drives The gears are connected to the top of the projector and the gears are rotated to rotate the projector. Belt drive is unstable. The belt is easy to slip, so there is no transmission. Therefore, I think that the belt drive is not suitable. Connected with rubber bands to simulate belt and chain connection during actual operation.

This model improves the relationship between ergonomics. People feel more comfortable using it.

I made 2 types of models. One is the gearbox model and the other is the sports equipment model. The gearbox model is used to check if the gears rotate smoothly. The sports equipment model tests which shape suits the user's experience best.

It improved PLAN B. Adjusting the angle of the cross structure increases the distance between the handle and the seat.

The user sits very ďŹ&#x201A;at in use because the bottom of the model is very large and strong. However, the user is too comfortable to use. It will not be like ďŹ tness.

The distance between the seat and the handle is too small for the user to feel uncomfortable.

When the user uses it, it buckles and looks at the projector. Similar to cycling. The feeling of movement of the product is improved.

PLAN A The seat and pedal are too close, and the user can not stretch the foot during use. The handle is also very close to the seat, which is uncomfortable for the users.

PLAN B The seat is too high, as that the user could step on the pedal.The ergonomics the upper limb is right when the User uses it. Customize the part of the cross to the distance between to change the seat and the pedal.

PLAN B + Feasibility and gear rotation were tested using a mannequin and a paper model. The gears can turn very well. The mannequin limbs integrate well with the components of the model.

Placement method sports equipment I collected some pictures of bus stops, which are more common in China, and sorted out the layout. Using these numbers, I suggested three options for the placement of sports equipment. Bus schedule

Seat

Use 3D printing to print the model and test its feasibility. The mannequin foot pedal drives the gear to rotate, which starts the projection. Tested through a combination of a 3D printed model and a human body model. This 3d printed model ďŹ ts the human body.

During the usage process, users can see how their kinetic energy is being converted into electrical energy. This will allow the projector to start and improve its user experience. Turning the gear will start the projector. The information required by the user will be projected onto the projector.

When the user uses it, he looks at the screen. After a few minutes of pedaling, the required information is displayed on the screen. This behavior is very natural and ďŹ&#x201A;uent. What the user has to do is practice, and then they can get the arrival information of the bus.

Komprimierter KoďŹ&#x20AC;er The suitcase is an object that people often use when traveling, and is therefore indispensable. When not in use, it takes up a lot of space at home. Especially in a small house, where the space is already small, this is a big problem. I propose a completely new way of storing suitcases.

Market size statistics of China's suitcase in 2012 ~ 2017 Due to the increase in travel and business travel, luggage has become a fast growing product in recent years. The domestic economy and the tourism market are developing well and the future luggage market is huge.

*Source: questionnaire In my research, most people have suitcases. Only one person did not use the case, but he said that if you want to go in the distance, you should buy a suitcase. It can be seen that the scope of use of the suitcase is very large. The 26 ~ 32 inch case is the best selling and most popular because it can hold many things. This case-sized case is important when you need to pack more things, especially when you travel long distances.

The 22 ~ 24 inch case is also very popular and can hold most of the items that people need on short trips. 19869

The 20 inch case is the entry level machine. Due to the capacity problem, the sales volume is not high. Normally, every human needs only once.

This table describes the average number of trips for people of diďŹ&#x20AC;erent ages in 2017. The table shows that most of the people traveling in China are young people between the ages of 20 and 29. In China, most people who like to travel are young people. The 30- to 39-year-old group has entered a stable business period and has begun to pursue quality of life while at the same time having an economic basis. The 20- to 29-year-olds strive for independence and freedom: the ďŹ rst time they enter society, they have strong social desires and exploration needs: the economic foundations are weak, but they strive to become opinion leaders

The per capita residential area of major cities in China is small.

The residential area per capita in Germany is large, except in certain cities with higher real estate prices.

The student residence in China is built by the school, and there is a uniform area standard in China: The average student dorm is a room for 4 to 6 people, located in a small area. Therefore, the average living space of the students is low. A small number of students rent a house, but since the students have little money available, their neighborhood is not large.

In Germany, the situation of the Shared rent is more common, not just the young people who work, and the students choose the Shared rent.

Most other people who choose a shared ďŹ&#x201A;at are young people who are just beginning to work. Due to the expensive rent, they can only rent cheap and small houses.

student apartment

German student apartments are much better than Chinese student apartments and each have a separate room and a separate toilet, which corresponds to a small single apartment. Student apartments are cheaper than shared apartments, and the number of places is limited, and most students who do not rent a student apartment still choose shared apartments.

The trunk has a big footprint. When not in use, it not only occupies a large position but is also unusable. I examined 48 diﬀerent houses and the arrangement of their suitcases.

Most young people have 2 or 3 suitcases, but their rooms are small. The trunk has a big footprint. If it is not used, it not only occupies a large position, but is also unusable. The case needs a lot of space and can not be stowed well. They decide to put the suitcase in the corner so that it does not interfere with daily activities. This is a good situation. But due to the small size of the house, it is very inconvenient if you want to put other furniture or objects in the room. Since the space occupied by the trunk, can not be reduced, no other furniture can be parked.

Suitcases in most people's rooms are accounted for a large room. Some people choose to put things in their suitcases for daily use to indirectly solve the problem of luggage usage, but it is still very uncomfortable. To put things in the suitcase is not convenient. Put things on the suitcase, not clean. 59

If the trunk is not used, this is the item that is in the room, just as the luggage is in the trunk. The room is equipped with a suitcase with luggage. Can the suitcase be like the luggage? Compressed and placed in the room?

Luggage from the room

Luggage from the suitcase

room

The suitcase is the luggage of the room. We can compress the suitcase like compressed luggage. Compressed luggage can reduce the space requirement.

suitcase

Compressed luggage can put more things in your suitcase, as well as compressed luggage can increase the space, put up more furniture and items and people have more space for activities.

luggage

Maybe we can compress the case like a compression bag. Can the suitcase be squeezed? How can we reduce the size of the case when not in use? However, the directly compressed luggage has some disadvantages in use and storage. I have tested a suitcase.

Can the suitcase be folded up? It does not look that way. Although it is a soft cloth, it has a strong support structure and can not be folded. At the same time its support and stability in the use of the trunk are unstable.

Can the suitcase be compressed from top to bottom? Obviously not. The luggage needs some assistance to ensure that the luggage is protected inside. I have checked this suitcase, which is thin but has strong support. It is hard-shelled and can not be compressed and folded.

Are there possibilities? We can make the compression bag suitcase. Can the compression bag replace the luggage to wrap the luggage? What advantages and disadvantages does the direct use of a compression bag have? What is the wear resistance of the compression bag?

The volume of compressed things has declined signiďŹ cantly. When the air is reduced, the object becomes shallow and hard, which supports the entire compression bag and the contents inside. It can hang or hang and the shape does not change. This is completely diďŹ&#x20AC;erent from the state of soft cotton before compression. Since it is made of plastic, it is easily broken.

The materials I use are: plastic plates, foam board, compression bags, model wheels. If in production the gripping part can be made with the compression bag, it is a whole. Here we can only use plastic for cutting and connecting with the compression bag. Cardboard is attached to the bottom and combined with the wheel. The wheels are added to simulate the pulling. After completing the model, I packed my luggage and compressed it. Then I will test the model. 69

Model1 outdoor test I took the model out to test its wear and its stability. I use it in the subway, in the subway station, on the escalator, in the street.

Improve grip

I check the model again after the test.

During the test I noticed: 1. By using the compression bag, the model has suďŹ&#x192;cient support and can be pulled easily. 2. If the ground is big and stable, we can put more things on it. 3. The handle is not stable enough and can be improved. 4. It has only one layer of plastic casing, which does not protect the luggage very well.

Compare model 1 with the case Can it stand by itself?

How big is it?

The model is smaller than the suitcase. I put the same clothes in the trunk and the model. It can be seen that the position in the trunk is large and occupies half of the position.

The suitcase can stand and my model must be held in the hand.

Is the handle easy to use?

The luggage can protect the luggage very well. The model is that the plastic bag is easy to break and the case is not protected. There was no change after the suitcase was dropped. But the model broke. The box at the bottom of the model is broken.

Is the outer case strong?

First test

Second test

Third test

Fourth test

The handle of the case is very comfortable and my model is not comfortable and even broken. The case is very heavy and the model is very light. On the side of the trunk there is a handle, the model is not. 73

protection test

Two eggs were placed in the trunk and model to simulate the luggage inside, and the trunk and model were tested. To check the protection of the baggage, I let it fall to the ground until the eggs were broken in it.

I threw it into the grass and the ground, and crashed it from diﬀerent angles. For the ninth time, the eggs in the trunk had broken. Prove that the suitcase can protect the luggage very well.

The eggs in the model were broken only after 7 times. Since the model has only a thin plastic bag housing, it does not protect the luggage.

To ﬁnd a better way to protect my luggage, I used two plastic bags to simulate. Inﬂate in an outer plastic bag, attach a small plastic bag in the middle of a large plastic bag and lay the eggs.

After ten times the eggs are still intact. This proves that this method is feasible. Inﬂating in an outer plastic bag protects the luggage well. 76

Use glue instead of screws to attach.

make the second model Can the suitcase be compressed from top to bottom? Obviously not. The luggage needs some assistance to ensure that the luggage is protected inside. I have checked this suitcase, which is thin but has strong support.

I glued the bottom plate and the plastic bag stuck with a glue gun.

It is hard-shelled and can not be compressed and folded.

Model 2 test The air space wrapped the luggage perfectly. The inďŹ&#x201A;ated part protects the luggage very well.

The foam sheet was not strong enough during the test and bent. It can be replaced by a plastic plate in production. It can easily be mentioned and stand.

airspace

Four wheels ensure that the case can stand. On the outside there is a inďŹ&#x201A;ated part package to protect the luggage. In actual production, the plastic of the outer case can reach 0.3mm, which ensures that it will not get scratched After the model test, the airspace was still airy and not damaged.

Plastic plate

IDEA 1 Adding an airspace to the outside can better protect your luggage. It simulates the appearance of the suitcase. At the same time, the part of the plastic bag is opaque, and when it is brought outside, others can not see what's inside.

folding program Separate the tire part from the case to make it easier to take.

IDEA 2

IDEA via valve There are two valves. One is for inďŹ&#x201A;ating and the other for pumping, which corresponds to diďŹ&#x20AC;erent rooms.

The shape of this idea is more like a paper bag. This is for folding and pulling back like a paper bag.

Or there is only one valve on the outside and another inside.

IDEA 1 In order to better represent the shape, I have created a paper model. I have produced 3 paper models of various sizes and shapes to examine the shape and structure. This model kit simulates the appearance of a conventional suitcase. A square shape like a suitcase is indeed possible. This appearance makes the case look more like a suitcase and is easy to stow away during transport.

Both ends of the airbag are not fixed. One is to protect the luggage to inflate better. At the same time, the plastic plate in which the wheel is to be firmly connected to the lower plastic plate. The suitcase folds up and saves a lot of space, as thick as a book. It can be set up anywhere and does not occupy a large space. During the folding test, I found that the folding effect of the two appearance models is the same. The model that simulates the appearance of the shopping bag does not fold better. The model of the simulated luggage is better in other ways. In the end, I chose the model that simulates the suitcase.

airspace valve

compression valve

The external valve is larger than the inside. Therefore, it is possible to inﬂate in the air space. Inside is a separate lid, which can be closed after pumping.

To better express the structure and the folding effect, I made a paper model. The middle part is the part where the luggage is, and the outside is protected by an air space. There are two valves at the same time, one is inflated and the other is pumping. The suction valve is the luggage space for more luggage. The inflation valve is used to inflate the outside air space.

Die dritte Hand For many people who enjoy cooking, cooking is a pleasure. But for those who do not cook, cooking is tough. To help them prepare

These are the photos I have collected from my friends. They enjoy cooking and are happy to cook. Although they can not cook well, they are ready to learn and make progress.

Many people like to cook at home. This is a general phenomenon. Although cooking is not the ďŹ rst choice anymore, that does not mean nobody cooks at home. On the contrary, people are more and more excited about cooking because the meaning of cooking has changed and the stomach is no longer full.

100

Do you cook at home? To get these answers, I sent a questionnaire to 90 people. I ask them ďŹ rst, do you cook at home? After completing the data, I received the following form.

How often do you cook at home? collected the frequency people use to cook at home every week I. The number of times is calculated by taking 3 meals daily for 7 days a week. Up to 21 times a week, at least 0 times.

According to the results of the survey, most people cook at home, and the number of people under 22 who cook at home is very low. Older people cook more often at home. Based on the sample data, there are more people between 23 and 29 years. It can be seen that people of this age are cooking at a high frequency. Most people cook four to twelve times a week at home, which is relatively modest. Since some people do not take breakfast at home or lunch at school, not many people often cook at home. Most people in the data are over 45 years old and will eat at home everyday because they retire.

The process of cooking can make people happy even though the dishes are very tired.

Cooking is one thing to watch out for and take time for the treatment.

Enjoy life. Self-cooking is a way of life that you can do well with your heart.

It's a happy thing to do my favorite meal for myself while I want to rest.

I have asked some people about their views and opinions on these learning methods and summarized them. advantages

This is a good way because someone teaches and does not experience mistakes in cooking.

The data on this page give an overview of how people learn to cook. There are many ways people learn to cook and they are not single. Many people use them in diﬀerent ways. Most often the app recipe is used, followed by family or friends. There are very few people who read cookbooks to learn cooking, and none of the respondents studied at a cooking school.

107

Very convenient You can ﬁnd and learn many recipes. People can view recipes anytime, anywhere. There are very detailed steps.

Although it is convenient to use, it is impossible to detect the right amount of spice and cooking time. It is inconvenient to look at the phone while cooking, and the phone becomes dirty.

There are many interesting videos on the internet to help them learn how to cook.

In fact, it is diﬃcult for them to learn in such a short time. That's why they need to take their cell phone or iPad with them while they're cooking, which is very uncomfortable.

These videos are very short, usually 3 to 5 minutes.

This way is very interesting. At the same time you can make your favorite taste without controlling the recipe. If you think for yourself, this method is usually only suitable for people with a certain degree of cooking.

Although it is very interesting to think about cooking yourself, many experiments are required, otherwise it is easy to prepare strange dishes.

Cutting vegetables is more diﬃcult and the hard part is that it is easy to cut irregularly. And when cutting vegetables, people can easily cut their hands.

It is also diﬃcult to give ingredients. If it is not for experienced people, it is diﬃcult to give ingredients properly. In Chinese cuisine, the spices of many dishes are "moderate".

Improve idea 2

Use the magnet on the bottom to close it.

I use another spice jar that can be turned and opened. I install the part on the machine that can rotate it.

The bottom of the spice bottle is magnetised and can be closed tightly. When the spice bottle is turned to the hole, the magnet at the hole attracts the magnet to the bottom of the spice bottle. The spice bottle is opened and the spice poured out.

127

A rotatable part is mounted on the bottom and has two support points that control the switch rotation of the sauce bottle. This seasoning can be poured from the seasoning bottle.

128

Improve ideas 1 I put the magnet on the switch of the spice bottle. The magnet is sucked into the bottle mouth to make sure that the spice in the bottle does not fall out. I use another magnet to simulate the switch on the base. It sucks the magnet on the spice bottle and moves. The switch of the seasoning bottle is opened and the seasoning is poured out.

129

Improve ideas 2 I bent the iron wire to control the mouth of the spice bottle. The iron wire can control the rotation of the mouth of the spice bottle well. This program is feasible. This spice bottle opening can be easily rotated with only two points of support.

But improving ideas 1 is easier and easier to implement, so I choose to improve ideas 1.
