[0003] In March 2004, the N900 card-type
mobile phone produced by NEC Corporation of Japan was the thinnest and lightest
mobile phone at that time. Its thickness was only 8.6 mm and its weight was only 70 grams. The
handset and
microphone must be connected to an external
headset to answer calls, which is very inconvenient
[0005] The thinnest and lightest smartphones produced by the above companies at that time involved several new parts, new technologies, and new patents. It was very difficult to make progress every time. At present, the thinnest smartphone is 4.75mm, and the lightest is 105g. But they don't meet people's demands for the thinnest and lightest, and they are expensive, difficult to repair, and not waterproof
[0006] On January 27, 2010, Apple released the first
tablet computer iPad, with a thickness of 13.4mm, a weight of 680-730g, and a screen size of 24.64cm (9.7 inches). 7.7mm, weight 558g, screen size 25.65cm (10.1 inches); 2013.10.22, the iPad Air produced and released by Apple Inc. has a thickness of 7.5mm, weight 469g, and a screen size of 24.64cm (9.7 inches); 2013.10.22, Apple Inc. The iPad mini 2 produced and released has a thickness of 7.5mm, a weight of 331g, and a screen size of 20.07cm (7.9 inches); in October 2013, the S5000 produced by China Lenovo Company is the lightest
tablet computer in the world, with a thickness of 7.9mm and a weight of 246 -249g, screen size 17.78cm (7 inches), 2014.02.18, Xperia Table Z2, currently the thinnest
tablet computer produced by Sony, has a thickness of 6.4mm, a weight of 426-439g, and a screen size of 25.65cm (10.1 inches). Among several tablet computers, the thinnest is 6.4mm, and the lightest is 246g. People always hope to get lighter and thinner tablet computers, so they cannot meet people's requirements for the thinnest and lightest
[0009] The above-mentioned products are all composed of a tablet computer and a physical keyboard. They are combined together like a notebook computer. After separation, the tablet computer can be used independently. The tablet computer is mainly composed of a
central processing unit-CPU, controller, memory, Memory, SSD hard disk, touch screen, battery and casing and other hardware and
software components, so it is difficult for them to achieve ultra-thin and ultra-light, so these mobile devices cannot meet people's requirements for ultra-thin and ultra-light
[0010] 1999.11.09, US patent #5983094-Disposable
Cell Phone applied by Randice-Lisa Altschul, using this patent to produce the thinnest mobile phone in the world at that time, it uses new technologies such as thin film circuit boards and disposable batteries, and its thickness is only 3mm. But it can only be used for 60 minutes, its life is extremely short, and its functions are simple, which can no longer meet people's requirements; It looks relatively thin when it is opened, but the whole
machine is still very thick after folding, and it cannot meet the thinner and lighter mobile phones that people hope; 2012.06.08, a Chinese utility model
patent application invented by Chen Huaqi and others No. 201220268722.1 - an ultra-thin mobile phone. This patent proposes a new structure to improve the charging jack and earphone jack of the mobile phone. The purpose is to reduce the thickness and weight of the mobile phone, but the progress of this small improvement is very limited.
[0011] Existing mobile devices such as smart phones, tablet computers, smart watches and handheld game consoles, their
central processing unit - CPU, controller, memory,
internal memory, screen, battery and shell and other hardware are assembled together to form a complete The space and volume of mobile devices are very limited. People's requirements for mobile devices are: not only want it to have more, faster and stronger functions, but also want it to be ultra-thin and ultra-light, and also want it to be cheap and convenient Maintenance, etc. Although ultra-thin and ultra-light mobile devices such as smart phones and tablet computers have appeared in the field of products, technologies and patents, the above analysis shows that the existing products, technologies and patents are difficult to meet people's needs. conflicting desires
