Title: System and method for producing a mixture of liquids

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a U.S. National-Stage entry under 35 U.S.C. § 371 based on International Application No. PCT/EP2018/073467, filed Aug. 31, 2018, which was published under PCT Article 21(2) and which claims priority to German Application No. 10 2017 216 336.4, filed Sep. 14, 2017, which are all hereby incorporated in their entirety by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure concerns a system and a method for producing a liquid mixture. 
     BACKGROUND 
     In many areas of daily life, there is a continuing trend towards personalized programs that address the individual requirements and needs of a customer or user. This is the case, for example, in the areas of nutrition or health care and also in the field of personalized cosmetics. This enables the consumer or user of cosmetic treatment products to receive individual treatment instructions and cosmetic treatment products that are specifically tailored to the individual needs of, for example, his or her hair, skin or teeth, thus enabling a particularly high degree of effectiveness. 
     Untrained hairdressers often lack experience in dealing with damaged hair. For example, it is difficult for young hairdressers to find out which hair treatment products are suitable for which customer in the hairdressing salon and in which proportions cosmetic treatment products such as shampoo, conditioner, hair treatment or hair dye have to be mixed optimally for a certain customer or to select a hair treatment product that is optimally designed to the condition of the hair. It is therefore a particular challenge for the hairdresser to achieve the hair colorings effect desired by the customer in the case of an existing hair damage of a customer. It is also difficult for the user who buys cosmetic treatment products and applies the cosmetic treatment products himself, for example at home, to achieve an exact mixing ratio, for example of hair treatment products or hair coloring components. 
     For example, a customer&#39;s or user&#39;s degree of hair damage is assessed subjectively, for example visually, and often based on the subjective assessment of the hairdresser or the customer a cosmetic treatment product is chosen which is not optimally suited to the individual needs of the user&#39;s hair. 
     For example, manually mixing different hair treatment products, such as components for a shampoo, conditioner, hair treatment or hair dye, is a challenge for the hairdresser or the user himself. An optimal mixing result can only be achieved if the individual components are mixed exactly in their predefined proportions. When manually mixing several cosmetic components from bottles, for example, a portion of one component may remain in the bottle excessively, so that the mixture may lack a portion of the one component.

     It may also be desirable that a mixture of different cosmetic products can be carried out quickly. It may also be desirable that several cosmetic products should be mixed quickly one after the other under the same conditions. This may be the case, for example, in a hairdressing salon, where several customers are to be treated one after the other, for example with a hair care or hair dye. 
     It is also desirable to be able to maintain a standard of hygiene when mixing at least two components. 
     When treating a user&#39;s hair, it may be desirable to be able to draw on information or experience collected or archived during a previous treatment of another or the same user&#39;s hair with a cosmetic hair treatment product, for example as information or data on a server or cloud. 
     It may also be appropriate to allow the hairdresser or the user to access a cosmetic consultation system from his or her smart device, for example his or her smartphone or tablet, for example from home or even on holiday.

     The configurations and advantages described above refer to the system and the procedure. 
     In this respect, directional terminology such as “top”, “bottom”, “front”, “back”, “foremost”, “rearmost”, etc. is used with reference to the orientation of the Figure(s) described. Since components of exemplary embodiments can be positioned in a number of different orientations, directional terminology is used for illustration purposes and is not restrictive in any way. It goes without saying that other exemplary embodiments can be used and structural or logical changes can be made without deviating from the scope of protection of the present disclosure. 
     Furthermore, it goes without saying that the features of the various exemplary embodiments described herein may be combined with each other, unless specifically stated otherwise. 
     In this context, “color” may be understood to mean a combination of a shade of color (i.e. a spectral color impression, also called hue, which may be understood to mean what is considered to be the “actual color”), a color intensity (i.e. how intense the color appears, e.g. compared with a neutral grey, which is also called saturation, color saturation, colorfulness, chromaticity or color depth) and a brightness (i.e. how light or dark the color appears). 
     In various exemplary embodiments the color information can, for example, be parameterized in a known color space, for example in a L*a*b* color space (where L* indicates the brightness of a color, a* the green and red components and b* the blue and yellow components of the color), in a RGB color space by color components in red, green and blue, in a CMYK color space by color components in cyan, magenta, yellow and black, or in any other color space. 
     In this context, the term “shade of color” may be understood to mean a color value or the spectral color impression of a color, regardless of how it may be parameterized, for example as a point in a two-dimensional color space (e.g. a*b* of the L*a*b* system) or a ratio of color components (as in the RGB color space or the CMYK color space). 
     In various exemplary embodiments a color space from which the color information (skin color information and image color information) originates can be such that a determined or represented color is independent of a medium through which the color is determined or represented (e.g. screen, printer, scanner, human eye, etc.). The color space can be, for example, an L*a*b* color space, the color information a shade of color parameterized, for example, by employing a* and b*. 
     In the case of a smartphone mentioned herein, unless the context indicates otherwise, this is to be understood as representative of all similar types of portable data processing devices, i.e. smartphones, tablets, laptops, etc., and the same applies analogously to smartphone cameras, etc. 
     In this context, a computer app can be defined as application software for mobile devices or computers or mobile operating systems. A computer app may provide digital information to a user and may include a user interface, such as a graphical user interface for a user&#39;s interaction with the computer app. 
     In this context, a peristaltic pump or a squeeze pump or a hose pump may be understood to be a positive displacement pump for pumping or transferring liquids. In the case of a peristaltic pump, a liquid to be pumped can be forced through the tube by external mechanical deformation of a tube. In operation, a tube is supported on a pump head casing while the tube is clamped from the other side by at least one roller or shoe rotating on a rotor (radial action system) or moved by a camshaft (linear or horizontal action system). The movement causes the clamping point to move along the hose, thereby allowing the pumped liquid to move forward. In the case of peristaltic pumps, the elasticity of the tubing material can create a suction pressure. 
     In various exemplary embodiments a peristaltic pump can be provided, which can have a large pump head, a large diameter of the pressure rollers and an asymmetric tube path, whereby the asymmetric tube path can further increase the effective head diameter. 
     In various exemplary embodiments it can be achieved that a life span of the tubing can be substantially increased and consequently a flow rate can be kept constant for a longer time and a pulsation of a liquid flow in the tubing can be substantially reduced. 
     In this context, laminar flow can be defined as a simple flow whose behavior is determined by the internal friction in a liquid. In other words, a laminar fluid flow in a pipe exists if the fluid can be divided into an infinite number of infinitely thin concentric hollow cylinders. For example, in laminar flow, such as in viscous fluids such as a shampoo, conditioner, deep conditioner or hair dye, the layers of fluid slide smoothly over each other. Acceleration and velocity of liquid particles can be described by two parameters: internal friction is the force acting per volume in the liquid, described by the equation 
     
       
      
       F 
       r 
       =η×Δv  
      
     
     where η is the viscosity of the liquid and v is the velocity of the liquid particles. The second parameter is the pressure gradient 
     
       
      
       R 
       p 
       =−dp/dx  
      
     
     where p is the pressure. In laminar flows no significant mixing processes occur. 
     In this context, the term viscosity can be used to describe the viscosity or tenacity of liquids. The greater the viscosity, the more viscous or less flowable the liquid is. The lower the viscosity, the thinner or more fluid the liquid is, so that the liquid can flow faster under the same conditions. 
     In this context, the term “viscous liquid” may be understood to mean a liquid whose viscosity can be at least about 2,000 MPas (megapascal seconds), preferably in a range of from about 5,000 to about 20,000 MPas. The viscosities of the cosmetic treatment products manufactured, in particular of shampoos or conditioners, preferably also have a viscosity of at least about 2,000 MPas (megapascal seconds), preferably of from about 5,000 to about 20,000 MPas. Viscosity is determined under the following conditions: Brookfield DV 2+, spindle 5, 20 rpm, 20° C. and 60 seconds. 
     In this context, a non-Newtonian fluid may be understood to be an anomalously viscous fluid whose deformation behavior can no longer be described using Newton&#39;s law. The viscosity of non-Newtonian fluids changes in particular with shear rate and/or load duration. 
     Non-Newtonian fluids can have a viscosity that changes with the load. This is due to the molecular structure or the interaction of the phase components, which show a different behavior in the case of strong movement, for example shear, than they do in a state of rest. The power required for mixing or stirring cannot increase linearly with the velocity of gravity in non-Newtonian fluids, but can be an exponential function. 
     In other words, a non-Newtonian fluid may originally have a viscous consistency, but when subjected to a force, it may become less viscous during the application of the force. When the force applied to the liquid is removed from the liquid, it returns to its original viscous state. 
     In this context, the term thixotropy is used to describe a phenomenon whereby viscous or highly viscous liquids, such as gels, shampoos, conditioners, hair dyes, creams, etc., become more fluid or less viscous when mixed or stirred or shaken and then solidify again. A thixotropic system can be a non-Newtonian liquid in this case. These material systems are exemplified by the fact that they can change their flowability when external forces are applied.
