Hello everyone, I wrote articles related to massage chairs a few years ago, and everyone has been urging me to do high-end ones. Since that article, all kinds of turbo worms have sprung up like mushrooms online, and even worms are not clear about. Product managers pretending to be industry insiders and giving you all the practical things to sell goods in the name of popular science. Today, I will also come to have a fight with the navy and give you some popular science. As the most important core component of the massage chair, it is also the part of the various navy's troubled waters that bring the most private goods - the movement, how to distinguish 1D~4D.
According to the latest upcoming GB/T 26182-2022 standards, massage chairs are classified according to movements:
The upcoming new national standard
Of course, companies that compile the standards do not rule out the possibility of private goods being entrained, but since it is organized by many companies, it is in line with the interests of each company and general standards. Well, I don’t talk much nonsense. Let’s analyze this standard and the identification method:
1D massage chair
The legendary Xiuyu movement
Wholesale massage mat body
1D movement , Keywords: 6D 8D Jade movement Xiuyu movement, magnet movement . Massage pillows, massage cushions, and massage chairs of more than 1,000 to 2,000 massage chairs on the market are basically all this. Simply put, it is a massage cushion with a massage chair vest (because the high-end massage cushion has guide rails, although the position cannot be controlled like 2D, it is at least 1.5D), and a low-end leg beauty machine and arm airbag are given. If the budget is not enough, it is recommended to buy a better cushion to save money and space, and the effect is good.
2D movement Keywords: Induction 3D strong 3D ancient method 3D 3D etc. Does not focus on whether it is airbag or mechanical 3D movements basically belong to spring 2D movements. In fact, the 2D movement is theoretically just one: a plate-type four-ball device. I believe that most people in the industry don’t know this name, hahahaha. Maybe each company has a different name. This is how the company that invented the plate-type four-ball device is translated. So what does he look like? The most famous 2D movement on the entire network should be the picture above, the 2D movement with all stainless steel violet. Basically, students who buy massage chairs online have seen this photo. In fact, it is sufficient to have independent driving devices (kneading motors and walking motors) on the upper and lower Y-axis and left and right X-axis. The architecture of large and small factories will be slightly different, and the setting of the motor and reduction ratio ratio will also make the body feel different. However, the optimization direction of 2D movements is basically to reduce costs, so the 2D movements on the market are the same. It is good to choose a large manufacturer to use high-end programs left by ancient times. But tens of thousands are too much.
narrowly, the only mass-produced 4D movement
4D movement , because there are fewer 4D movements and are not the focus of this article, we put it in front. Let’s first look at what the new national standard says. The original text is: Based on the 3D movement, under the control of the supporting control system, the movement of the massage head can achieve coordinated control of the three axial directions of the space, and have the ability to plan and execute the space trajectory. In fact, according to the narrow literal meaning, the mass-produced movements on Earth, the MA70 and above models of Sonyco flagship have the ability to plan and execute space trajectory. Simply put, it is possible to write, because the movement of Panasonic is not controlled by worm gear and worm (the driving devices of other movements are: 1. Walk up and down, 2. Knead (the turbo or worm that draws circles) 3. Hitting (the same for everyone) 3D (airbags or gears or push rods, etc.)) The key is 2. Panasonic flagship movement is only responsible for left and right displacement. Therefore, the front, back, left, left, and bottom of this thing is only responsible for the XYZ axis movement. Simply put, the Panasonic movement can write and draw pictures, and other things cannot be planned and done.Of course, according to my review of patent documents, other companies have also developed it, but now Panasonic is the only one with a narrow 4D production. It is not impossible to write a word on other movements. It takes a long time to adjust it, and what is written is not that true. But now most navy soldiers or writers call warmth 4D another dimension. After all, everyone is so promoting it. Gong and Ultra Hertz add high-frequency dimensions, which is also considered a 4D that can be perceived in a significant difference from 3D. What is the inexplicable 3D that cannot be explained clearly? So when you compare, remember to identify and inquire about the difference between 4D and 3D of the target product. If you can't feel the difference, you are all fake. If you say more accurate, you are also fake. If you say that you have more distances, you are also fake. The 4D and 3D architectures and body feel are definitely obvious so that consumers will use them or just look at the movement structure. I won't name specific products here. Everyone is welcome to use the products to discuss PK~
3D movement renderings
3D airbag 3D with market price of 68800 3D
3D movement, keywords: airbag 3D radial motor, gear 3D, mechanical 3D, air sensation 3D, air suspension 3D, etc. . Basically, big brands now start from 10,000 yuan, and do not have a cap on top. They all belong to 3D. According to the national standard, outside the upper, lower, left and right dimensions, they can be driven and controlled on the Z axis perpendicular to the back of the human body, which belongs to the 3D category. Here we will explain that there are many 3D driving methods including but not limited to gears, airbags, screws, push rods, crankshafts, and other methods. Obviously, as it is an additional control dimension than 2D, it increases the motor, movement complexity, driving circuit and cost. The body feel is also different from the 2D big selling point. Each company will definitely write a lot, at least it should explain the way it is launched. Some brands of water soldiers are crazy about their presence. When they say that this is an airbag, the gear is too old. When it comes to their own 3D principle, a simple Texas Instruments chip (who asked you the chip? Does others have no chips) made of stainless steel (who asked you the material, are you stupid for consumers?) I have been fooled, please pay attention to the screening. Generally, consumers basically start to buy real 3D. The movement is already good, and according to the positioning of the brand, it is already above the mid-range. Because the life cycle of massage chairs is relatively long, such products are basically still mid-to-high-end within 3 to 5 years. Even if you don’t know how to use them, you will not have a particularly obvious leap like 2D~3D. It is a one-step choice. Because I often see a few naval forces who don’t understand at all or writers who write randomly, I will pick a few naval forces here that often reverses the concept of right and wrong. I will listen to it. Everyone is welcome to PK
1. Is the plastic movement definitely not as good as the eight-star eight-arrow surgery and aerospace-grade aluminum-magnesium alloy movement? No, the mass production of a product is in multiple dimensions, and the underlying planning, architecture, materials, costs, working hours, maintenance convenience, etc. all need to be considered. It is true that the production and forming cost of polymers such as plastics will be lower, but it also brings other cost controls such as assembly labor hours, so that this part of the money can be used in a place that the development department thinks is more meaningful, so the product is a balance between cost and market. In terms of pure materials, the performance of metals will indeed be excellent, but if it is a 3D plastic and 2D metals, if it is me, as long as it is a product from a large manufacturer, of course, choose 3D at the same price. There are many thief merchants here. Because they are 2D, they are just talking about it. They say that the mechanical 3D is plastic. There is a piece of plastic in this airbag 3D, which is not pure steel. When it comes to myself, they don’t talk about launching springs all over, but only say that we are stainless steel. Our XXX chips are actually 2D and they dare not show them generously.
2. Is airbag 3D definitely not as good as mechanical 3D? No, there are good or bad airbag 3D, and there are good or bad mechanical 3D.The 3D machine that is purchased by small factories and the 3D airbag that is developed by large factories with air pressure sensor sampled according to the force. Can you tell which one is better and which one is worse? What about the bad rate? It can only be said that the lower limit of mechanical 3D is very low (it is not as stiff as that of airbag 3D, which is not as elastic as that of airbag 3D). The upper limit is very high (most advanced movements are currently launched by machinery, but they are not the same as the bargains bought by most people). The lower limit of airbag 3D is slightly higher, and the upper limit is not as good as that of mechanical 3D. (However, the most expensive massage chair in the world, LPN-30000 is indeed the Airbag 3D. Which company dares to say that it has a comprehensive market price of 68000?) So if there is a seller who sells goods regardless of the specific style and architecture, it is bad in a nutshell, then it is either stupid or bad. Just block it.
3. Is the ancient movement the best? Of course not, I smiled at me. It’s like if modern people have some difficult and complicated diseases, they don’t go to the surgery to find the miracle doctor Xilaile. According to current science and technology, Hua Tuo came to take the entrance examination for the Geriatric Medical University. It’s okay if you talk about ancient methods. After all, many programs are now composed by young people. They have not been engaged in their career for a long time and have no theoretical support. The programs are more mechanized (good movements are important, but the priority level of programs is not lower than that of movements). But ancient methods, aren’t you just using , big brother, big on the street now, and you can’t even call them.
4. I can’t continue writing this post, and I don’t post links or recommend models. Everyone is welcome to argue. The reasoned and well-founded stubs, disassembly stubs, and live broadcast stubs are all OK
