Spacers of varying lengths to control the length and style of hair cut may also be provided.

Self-hair cutting device

The United States Patent 4979303

An electrical motor-operated clipper comprises a pair of longitudinal blades, wherein a longitudinal movable blade having a rectangular slot on the back end is tightened to a fixed blade by a machine screw, a locking washer, and a belt-shaped spring. The electrical motor is mounted in a housing. The fixed blade projects from the forward end of the housing. A lever connects the movable blade in the slot to a transmission driven by the output of the motor and is rotatably mounted in a metal cover which is mounted in the housing. A two-line-teeth comb attachment can be attached to the longitudinal blades for guiding the haircut.

We thought of inventing the self-haircut machine for home usage, because of problems such as the huge cost of the barbershop, health concerns, and commuting problems. Using the device is very simple. When using the device, there is no need to change the level or comb or any other specific action by the user. The only thing he needs to do is move the device according to the pattern inside an application, on the points asked by it. Therefore, ha can trim his hair according to the desired hairstyle. Its working procedure is like this: the hair is sucked into the device by a small suction turbine. The hair is cut at the desired height with a blade equipped with a linear jack. It can work at a precisely adjusted height. The clipped hair is transferred by suction to the chamber at the end of the device and stored there. It is necessary to say that the movement pattern of the device on the head is according to the desired hairstyle of the user. The information is provided by the software, which is installed on the mobile (through Wi-Fi or Bluetooth module). In addition, during the haircut, the small camera installed on top of the device shows the area of the head under grooming. The device can cut the hair from almost 10 cm to 0 cm in height.

In many countries, the cost of going to the barbershop is very high. In certain countries, the cost of having their services may be more than 50 dollars. Other factors such as reserving, waiting time, commuting, hygienic issues, etc. weren’t considered in cost estimation. And in special cases such as the pandemic or during travel, there is no access to the barbershop. Meanwhile, for having trim hair, you need to go to the barbershop, at least every two weeks. This is not possible for many people because of financial or timing issues. Nevertheless, until today no device had been invented which give unskilled people the capability to cut their hair. Since if they want to do it by current devices, it is a very difficult and almost impossible task. The reason is that hair-cutting requires expertise, and it has these challenges:

You need to know to cut every part of the hair to which amount, it needs knowing the level (number) of cutting and appropriate comb.
The way of handling the haircut machines and the hand angle are very important. So the hair should be well-positioned in the path of the blade to cut smoothly.
The other problem is insufficient access and lack of correct sight for different parts of the head by the person himself.
The issue of cleaning and sweeping the clipped hair is the next annoying thing during haircutting.

So it is necessary to have a device that can overcome these challenges, has simple usage (for example being portable, small and lightweight) and its usage doesn’t require any special skill, be fast, and give the user the ability to cut his hair with the desired style with the least difficulty. It is argued that such a device eliminates most of these problems.

Solution of problem

To have tidy and trim hair you have to visit a barbershop at least twice a month but because of the cost of that or other hardships, people either go to barbershops rarely or cut their hair themselves that always doesn’t have a pleasant result! According to some statistics, every visit to the barbershop can cost you about 30$ on average but in some cities and areas, it can reach 100$. That this matter makes annual costs of going to barbershop more expensive than many other services such as internet, electricity, etc. So inventing a device that can help people to cut their hair by themselves with simple usage is an important mission. But it is easy to make mistakes while using these tools inside the house. So it is better to use an elaborate device but with simple usage.

In the previous part, the main challenges of haircutting by the person himself were introduced. Now some strategies should be applied to solve these challenges and direct us toward our conceived goals. To solve the first challenge, the device is connected to an application inside your mobile. Inside this application, all of the hairstyles are modeled as mathematical patterns. The size of each part of the hair and the corresponding comb is determined. In the next step, the haircutting machine receives its data from the application, and through the Bluetooth module. For simple usage and eliminating the necessity of changing combs constantly and simultaneously to the movement of the device on the head, a new system is implemented. A precise linear jack with a connected blade is included in the device. The length of the arm of the jack is changed with the application’s command. So it can cut the hair at different heights (according to the required pattern). According to this feature, this device can cut the hair from almost 10cm height to 0cm height, which is in contrast to other available haircutting machines.

Until now, we successfully overcome the first challenge, but the second challenge is still unsolved. We need a strategy that minimizes the dependency of performance to the angle of hand and type of handling. To resolve this challenge, a suction turbine in the vacuum and a comb are used. The size of the comb is from 10cm which is the highest level of cutting and corresponds to 0 of the arm, to the longest arm corresponding to the lowest level of cutting. They can help the cutting system (jack and blade) trim the hair efficiently by raising the hair and consequently increasing the accuracy of the cutting system. In addition, this suction helps resolve the fourth challenge and transfer the clipped hair to the embedded hair chamber and the environment is kept clean.

For solving the third challenge, a camera is added to the device. The user can have good accuracy, even in locations such as the back of the head that has insufficient sight. He moves the device precisely according to the shown pattern and in chosen points.

The working of the device is in a way that clipped hair is collected by a small suction turbine. The hair is cut at the required height with the help of a sharp blade and linear jack with precise positioning. The hair is transferred to the chamber which is positioned at the end of the device. A filter is responsible for the chamber from the suction. The way the device should be moved by the user on the head is provided by software installed on the mobile. The movement is according to the desired hairstyle. The connection is made through Bluetooth or Wi-Fi modules. For this purpose, the head is divided into various parts according to the desired hairstyle. Different hair height is considered for each part. It is worth mentioning during a haircut, the small camera installed on top of the device, takes a photo of the cutting area. This picture is shown on the user’s mobile, through Wi-Fi or Bluetooth module. This leads to higher haircut accuracy, especially in blind spots of the user.
