Before 2010, the cost for NASA to launch a rocket was US$380 million – equivalent to hundreds of Rolls-Royce luxury cars, which were all scrapped after being driven once. The high launch costs have become the biggest constraint on NASA's space exploration.
Elon Musk discovered this problem and founded SpaceX. In the past ten years, he has been exploring how to reduce the cost of space transportation and developed recyclable rockets that can be launched repeatedly. Finally, the cost of a single rocket launch was reduced to 60 million, less than one-sixth of NASA's.
Musk is considering that if rockets can be reused like airplanes, then the cost of entering space will be reduced to one percent. If going to Mars is like flying abroad, then human exploration of Mars will no longer be a fantasy.
This is Musk’s “first principle” for exploring space.
First principles are a method of thinking proposed by the ancient Greek philosopher Aristotle:
When thinking and acting, reason from the most basic principles and common sense. When a basic proposition or hypothesis cannot be deduced from other propositions or hypotheses, this proposition is a first principle.
In fact, in the field of engineering, products that make good use of "first principles" are always eye-catching. Looking across the stars and the sea, we will see recyclable rockets, but when we return to our own doorsteps, we can actually innovate products that follow "first principles" in cleaning home appliances.
For example, 3i is a smart purification station that “never changes the water for life.”
Rethink cleaning appliances and say goodbye to the era of water changes
In 1996, the world's first mass-produced sweeping robot was born. It was the earliest cleaning appliance in human history – it was named "Electrolux Trilobite" and was developed and manufactured by Swedish home appliance giant Electrolux. .
Foreigners define this category as "Vacuum Robot", which literally translates to vacuum cleaner robot. As an upgraded version of the vacuum cleaner, it can get under tables and beds to clean the floor by itself.
It can be said that the original intention of the invention of cleaning appliances was to liberate human hands.
But for Chinese users who “use water as their primary source of cleanliness”, floor cleaning actually includes sweeping and mopping. Chinese families, who have a special understanding and emphasis on cleanliness and hygiene, must have a need for floor cleaning. The addition of "water".
With the addition of water, robot products that integrate sweeping and mopping have emerged. While sweeping the floor, they can also mop the floor. It seems to kill two birds with one stone and is easy and enjoyable. But precisely because of the addition of water, the robot inevitably involves the "water up and down" issues of adding clean water and emptying sewage.
Forgetting to empty the sewage bucket is every user's nightmare.
In addition to mold and smell, the biggest problem is that it easily breeds mosquito bacteria and pollutes the home environment.
The original intention of the birth of the sweeping robot was to free human hands and improve cleaning efficiency. However, more often than not, the cleaning problem is just put behind the scenes, and the efficiency does not necessarily improve much.
It can be said that the problem of "water supply and drainage" is the "last mile" that is difficult for sweeping and mopping robots to reach.
When we re-examine the essence of floor cleaning, it actually means exchanging dirt from the ground into clean water, and then disposing of the sewage. What we need to solve is where the clean water comes from and where the sewage goes .
In this case, wouldn’t it be wonderful if the robot could process sewage by itself and produce water by itself?
This is to rethink the category of cleaning home appliances based on the "first principles" methodology.
The ultimate solution proposed by 3i smart purification station is to innovatively build a "water purification circulation system" to completely free users' hands.
With the "water purification circulation system", the installation of the base station does not need to consider the issue of water supply and drainage – this is also a pain point for many families. After all, not every house has suitable water supply and drainage channels, and pipe modification is also a big deal. expenditures. In contrast, the 3i smart floor cleaning station can be placed in any corner of the home, providing a one-stop solution.
In addition, the biggest benefit is that you only need to inject pure water into the clean water tank of the base station once. Subsequently, relying on the "purified water cycle", you can achieve a lifetime without adding clean water or pouring sewage.
The principle is easy to understand——
The "Sewage Purification Center" in the "Water Purification Circulation System" has two major functions: "disinfection" and "water production."
After the robot completes the sweeping and mopping work, the sewage generated by the roller cleaning and self-cleaning will be recycled into the sewage tank built into the base station.
At this time, the sewage in the base station will be heated to a slightly boiling state of 90°C. After being fully disinfected, it will be condensed into pure water through the distillation system and sent to the clean water tank to achieve purified water circulation.
At the same time, the base station will also judge the amount of water in the clean water tank. If the amount of water is not enough, it will automatically extract water through the air.
This "out of thin air" water extraction operation is a bit like an upgraded version of a dehumidifier. It directly draws air into the fuselage and obtains moisture through the condensation system. It is then disinfected by silver ions to obtain purified water, and is finally replenished into the clean water tank. .
This "water purification circulation system" achieves self-sufficiency in water tank disinfection and water production, and the "last mile" of the sweeping robot is easily solved.
Now that the technical principles are explained clearly, let’s take a look at the actual test experience.
Actual measurement: There is a smarter way to clean the floor
Sweeping robots have three main qualities: initiative, efficiency, and intelligence.
Being active is the duty of a sweeping robot, while being efficient is backed by innovative design. The key to whether 3i's smart cleaning station is easy to use or not is smart.
Let’s first take a look at the configuration of the 3i sweeping robot——
- Six-core CPU Quad-core GPU 4T high computing power NPU smart AI chip
- RGB camera
- Green eye laser module
- d-TOF lidar
- Infrared laser obstacle avoidance
- Brushless fan with maximum suction power of 8000Pa
- Four-wheel configuration (in addition to the double-side sweeping and mid-sweeping rollers, it is also rarely equipped with a mopping roller)
The first is mapping. The sweeping and mopping robot of the 3i smart cleaning station is equipped with a 2-megapixel RGB camera, dual-line laser and other sensors. In addition to having spatial perception capabilities, it can also restore furniture scenes on the map through image recognition.
The robot is equipped with a "green eye" module at the bottom. Through the forward irradiation of a medium-band green laser, different reflected light spots will be formed when irradiated with different dirt such as liquids, stains, solid particles, and dust.
The high-precision camera on the front of the robot can capture these light spot images, and combined with the AI deep learning algorithm, it can identify 52 types of dirt and common objects, and formulate targeted cleaning strategies to improve cleaning efficiency – dirty places will also be cleaned. Drag it back and forth several times to improve cleanliness.
The trajectory of robot sweeping and mopping also follows a "bow-shaped" trajectory to achieve area coverage, achieving a balance between efficiency and coverage. The rear roller can also reduce coverage dead corners.
The sweeping and mopping robot can also identify some common obstacles on the ground when working, such as standing humans, socks, shoes, etc. on the ground. After the robot recognizes them, it will actively avoid them, which is quite smart.
As can be seen through the glass floor, the 3i robot can use a roller brush to clean liquid dirt. The adsorbed sewage will also be scraped into the robot's sewage tank, allowing the roller brush to remain relatively clean, and then continue working.
The brushless fan connected to the middle sweep can provide a maximum suction power of 8000Pa, which can suck up all common ground dust, hair, snacks, as well as cat food, cat litter and other garbage.
In order to test the cleaning ability of the robot, we prepared some relatively common dirty garbage for it, covering dry garbage, wet garbage and even mixed dry and wet garbage.
Cantonese people always have a few potted plants in their homes. First, they sweep up the dead branches and leaves of the potted plants at home. When faced with the fine dry garbage, they do it all in one go, leaving no trace as they pass by:
The difficulty is slightly upgraded, and even the greasy potato chips that are scattered casually can be taken away and mopped clean:
In this case, we will directly increase the difficulty and let 3i face the mixture of yogurt and cereals. The result was that we could still take it away and wipe the floor clean, which really surprised us.
Thanks to the roller brush structure, the 3i smart floor cleaning station can also achieve a sweeping and mopping function similar to that of a floor scrubber. Therefore, the 3i robot can actually sweep and mop very cleanly even though it is also a "hell difficulty" tomato sauce. We were blown away by how well it cleans.
This means that it can clean many types of garbage commonly found on the floor of your home.
We often say that a mature sweeping robot can not only clean the floor, but also know how to clean itself. When the cleaning is completed, it will automatically return to the base station. While the dirt is discharged, the drum will also be washed with clean water and then dried by hot air. This is also very smart and worry-free.
In addition to the sweeping robot itself, the base station of the 3i smart cleaning station is also worth mentioning.
Not to mention the innovative "water purification circulation system", the base station is also equipped with a luxurious 13.3-inch large screen. This large screen can directly control all settings of the base station and robot, and can also intuitively see work data and consumable status on the screen.
The host also has a built-in voice assistant. For family members who are not familiar with smart appliances, they can also use voice wake-up to clean and sweep the floor, which is very convenient.
Interestingly, 3i’s product manager also exclusively revealed to Ai Faner that with the construction of its own smart home ecosystem in the future, this large screen will be able to do more and more things.
A smart cleaning station may turn into a smart housekeeper.
Finally, let’s talk about the water production capability of the base station.
For Ai Faner, who lives in Guangzhou, the 3i smart floor cleaning station is a good choice – Guangzhou has a humidity of around 80% all year round, and even in winter, the humidity is above 60%, which means it has a good water production environment.
To better simulate conditions in the north and south, we tried filling only two-thirds of the clean water tank with pure water. Then put the clean water tank back into the base station and start the test.
After a quick test, the base station continued to turn on the "air water production" function to replenish purified water into the clean water tank. In a room with an air humidity of 75%, it can produce about one liter of water in five hours. When the clean water tank is almost empty, the base station can basically complete the replenishment of the clean water tank in one day.
After a single cleaning, the base station will automatically complete the work of "distilling water". The average water production time is about ten minutes, which is relatively efficient.
We also simulated the usage scenario of a very large apartment. After dozens of sweeping, mopping and water changes, the built-in sewage tank was completely full. Then let the sewage tank distill the water, and it only takes more than an hour to completely evaporate it.
The benefits of using slightly boiling water distillation to treat sewage are also obvious. It can not only effectively settle impurities and dirt, but also kill H1N1 virus, Staphylococcus aureus, Candida albicans, Escherichia coli and other germs, meeting the requirements of clean water. standard.
Induction-free automation is the first principle of pure land
If you don't sweep one house, how can you sweep the world?
This is an allusion from "Book of the Later Han" written more than a thousand years ago.
It can be seen that since ancient times, floor cleaning has been a traditional chore in human society. It is a trivial and annoying repetitive labor that is always missed by people.
But today, this matter is indeed worthy of re-examination.
As a product that rethinks "cleaning appliances", the 3i smart floor cleaning station has a high degree of completion for its debut, and is the first to realize the best solution for the category of sweeping and mopping robots.
For consumers, "natural and non-sensory" should be the highest compliment for a technological product. The highest level of these convenient experiences based on advanced technology should be invisible, making people feel that these experiences "should be like this."
After a period of actual experience, we found that except for the occasional replacement of the dust box, we really do not need to have any interaction with this clean ground station during the day.
You don’t have to think about the placement, you don’t have to bother adding water, you don’t have to worry about pouring out the sewage, and you don’t have to worry about whether it’s clean or not – sweeping and mopping the floor is something you shouldn’t think about all the time. When you forget when you need to sweep and mop the floor, I think That's when productivity is truly liberated. We will also have more time to rediscover the leisure and ease that truly belongs to daily life.
Letting human beings free their hands, this is the first principle of "cleaning home appliances".
