Description:FIELD OF THE INVENTION

[0001] The present invention relates to a customizable sunscreen formulation device that helps users create personalized sunscreen by analyzing the skin's phenotypic conditions, such as acne, pore size, and other skin traits, to tailor the sunscreen’s ingredients and properties for optimal protection, absorption, and suitability based on individual skin needs and concerns.

BACKGROUND OF THE INVENTION

[0002] Sunscreen formulation is essential for protecting the skin from the harmful effects of ultraviolet (UV) radiation, which can cause sunburn, premature aging, and increase the risk of skin cancer. A well-formulated sunscreen contains active ingredients, such as chemical or physical blockers, that absorb or reflect UV rays, preventing skin damage. The need for effective sunscreen arises from increased sun exposure due to lifestyle changes, outdoor activities, and environmental factors. Its importance lies in safeguarding skin health, maintaining an even complexion, and reducing the risk of long-term skin damage. Sunscreen is a crucial component of a comprehensive skincare routine for all skin types.

[0003] Traditional methods of sunscreen formulation typically involve mixing active ingredients like zinc oxide or titanium dioxide (physical blockers) and chemical filters such as avobenzone or octinoxate with emulsifiers, stabilizers, and moisturizers to create a lotion or cream. While effective in protecting against UV radiation, these formulations often face drawbacks such as poor texture, greasiness, or visible white residue from physical blockers. Additionally, some chemical filters can cause skin irritation or be less stable under prolonged sun exposure, reducing the sunscreen’s efficacy. These formulations may also lack customization for different skin types or conditions, limiting their overall effectiveness and user comfort.

The T-shaped connecting pipe comprises a first input pipe, a second input pipe and an output pipe; the cosmetic emulsifying processor is used for mixing the cosmetic composition and emulsifying, and comprises an emulsifying pot body, a filler port and a discharge port, wherein the filler port and the discharge port are communicated with the emulsifying pot body, and the first input pipe is communicated with the discharge port; one end of the booster pump body is communicated with the second input pipe; the diamond interaction cavity is arranged on the output pipe; the heat exchange flow channel of the temperature adjusting module is spirally arranged on the outer wall surface of the diamond interaction cavity along the axis of the diamond interaction cavity; the first switch valve is arranged on the first input pipe and is used for selectively opening or closing the first input pipe; the second switch valve is arranged on the output pipe and used for selectively opening or closing the output pipe. The utility model ensures that the cosmetic material is dispersed, crushed and emulsified in nanometer scale, effectively reduces the size of emulsified particle diameter of the cosmetic and improves the uniformity of the cosmetic.

[0005] CN220003760U discloses a mixing preparation device for a cosmetics laboratory, which comprises a parallel mechanism and a clamp firmware for clamping a solidified cosmetics preparation container; the parallel mechanism comprises at least three linear degrees of freedom which are arranged along a coaxial line in a ring-shaped array, and the linear degrees of freedom are connected with the clamp for universal angle adjustment. high efficiency: the mixing preparation device adopts the structural design of the parallel mechanism and the linear module, can realize the efficient and stable cosmetic mixing preparation process, and improves the mixing efficiency and the preparation quality. The precision is high: by adopting the servo motor as a rotary executing piece, high-precision control of the linear module can be realized, so that the operation precision and efficiency of the hybrid preparation device are improved. The operation is simple and convenient: the mixing preparation device has compact design, simple structure, easy operation and maintenance, and is suitable for the small-sized preparation requirement of the cosmetics laboratory.

[0006] Conventionally, many devices have been disclosed for mixing preparation in cosmetics laboratories, but these devices typically lack the capability to assist users in formulating personalized sunscreen. These devices do not account for individual skin’s phenotypic conditions, such as acne, pore size, and other unique skin traits, which are crucial for tailoring sunscreen formulations. Without considering these specific characteristics, traditional devices cannot provide users with the precise sun protection required for their skin type, resulting in less effective sun care solutions. This highlights the need for a device that integrate skin analysis to create customized sunscreen formulations.

[0007] To overcome the aforementioned drawbacks, there is a need in the art to develop a device that assist users in formulating personalized sunscreen by analyzing the skin's phenotypic conditions, such as acne, pore size, pigmentation, and other skin traits. Such device would use advanced sensors or algorithms to assess individual skin types and tailor sunscreen formulations accordingly, ensuring that the sunscreen provides optimal protection and addresses specific skin concerns. By considering these unique characteristics, such device would enhance the effectiveness of sun protection, promote healthier skin, and offer more customized skincare solutions, particularly in varying environmental conditions.

[0019] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a customizable sunscreen formulation device, designed to helps users create personalized sunscreen by analyzing the skin's phenotypic conditions, such as acne, pore size, and other traits, to tailor the sunscreen’s composition for optimal effectiveness, protection, and compatibility with individual skin needs.

[0021] Referring to Figure 1, a perspective view of a customizable sunscreen formulation device is illustrated, comprising a body 101 arranged with a touch interactive display panel 102, an artificial intelligence-based imaging unit 103 installed on the body 101, a motorized gripper 104 with a contact probe 105 installed on the body 101, plurality of chambers 106 arranged inside the body 101 with an electronically controlled nozzle 107, a container 108 arranged underneath the chambers 106, a multi-sectioned box 109 arranged inside the body 101 having multiple electronically controlled spouts 110, a receptacle 112 arranged beside the container 108, a motorized grinder 113 integrated at base of the receptacle 112, a motorized stirrer 114 integrated at base of the container 108, a tray 115 arranged inside the body 101 and a robotic arm 111 installed inside the body 101 with a sensing module 112.

[0022] The device proposed herein includes a body 101 developed to be positioned on a ground surface for formulation of sunscreen. The body 101 as mentioned herein serves as a structural foundation to various components associated with the device, wherein the body 101 is made up of material that includes but not limited to stainless steel, which in turn ensures that the device is of generous size and is light in weight.

[0023] In order to activate functioning of the device, a user is required to manually switch on the device by pressing a button positioned on the body 101, wherein the button used herein is a push button. Upon pressing of the button, the circuits get closed allowing conduction of electricity that leads to activation of the device and vice versa.

[0024] Upon activation of the device by the user, an inbuilt microcontroller embedded within the body 101 and linked to the switch generates a command to activate an artificial intelligence-based imaging unit 103 installed on the body 101 to determine phenotypic condition of the user’s skin including acne or pores. The imaging unit 103 comprises of an image capturing arrangement including a set of lenses that captures multiple images in the surrounding, and the captured images are stored within memory of the imaging unit 103 in form of an optical data. The imaging unit 103 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines phenotypic condition of the user’s skin including acne or pores.

[0025] In response to the determined phenotypic condition of the user’s skin, a motorized gripper 104 installed on the body 101 is actuated by the microcontroller for monitoring skin type of the user via an integrated contact probe 105. The motorized gripper 104 operates as a robotic hand for monitoring skin type of the user via an integrated contact probe 105 effectively. The gripper 104 typically incorporates a motorized mechanism that controls the opening and closing of the jaws of the gripper 104. The motor generates the necessary force to move the gripper’s 104 fingers for the opening and closing of the jaws with precision. This motorized action is often controlled by the microcontroller for monitoring skin type of the user via an integrated contact probe 105.

[0026] Plurality of chambers 106 arranged inside the body 101 with an electronically controlled nozzle 107 are actuated by the microcontroller to dispense an optimum amount of the evaluated ingredients from the chambers 106. The electronically controlled nozzle 107 works by utilizing electrical energy to automize the flow solution in a controlled flow pattern by converting the pressure energy of a fluid into kinetic energy, which increases the fluid's velocity to get dispensed. Upon actuation of nozzle 107 by the microcontroller, the electric motor or the pump pressurizes ingredients within the chambers 106, increasing its pressure significantly. High pressure enables the solution to get dispensed out with a high force in a container 108 arranged underneath the chambers 106.

[0027] Multiple electronically controlled spouts 110 integrated with a multi-sectioned box 109 arranged inside the body 101 are then actuated by the microcontroller to dispense a required chemical agent in the container 108 to prevent any allergic reaction on the user’s skin as per the user’s medical condition. The electronically controlled spouts 110 functions through a network of solenoid valves, each connected to the microcontroller, that regulates the timing, volume, and sequencing of solution dispensed from each spout to dispense a required chemical agent stored in the box 109 in the container 108 to prevent any allergic reaction on the user’s skin as per the user’s medical condition in a receptacle 112 arranged beside the container 108.

[0028] Upon dispensing of the crystalline ingredient in the receptacle 112, a motorized grinder 113 integrated at base of the receptacle 112 is actuated by the microcontroller to grind the ingredient in view of maintaining a powdered form of the ingredients. The motorized grinder 113 works by using an electric motor to drive a set of rotating grinding components, such as blades or burrs, which crush and grind the ingredient into smaller particles; the motor's speed and power is adjusted to achieve the desired texture of the ingredient in view of maintaining a powdered form of the ingredients.

[0029] A motorized stirrer 114 integrated at base of the container 108 is then actuated by the microcontroller to rotate at a pre-defined speed for blending the ingredients to formulate the sunscreen. The motorized stirrer 114 operates by using an electric motor to drive a rotating shaft, which is connected to mixing blades or paddles designed to blend ingredients efficiently. The motor’s speed is controlled by the microcontroller to rotate at a pre-defined rate, ensuring consistent and uniform mixing of the ingredients, to formulate the sunscreen.

[0030] Upon mixing of the ingredients, a robotic arm 111 installed inside the body 101 and integrated with a sensing module 112 is actuated by the microcontroller to check parameters including viscosity and pH of the prepared sunscreen. The robotic arm 111 comprises of a robotic link and a clamp attached to the link. The robotic link is made of several segments that are attached together by joints also referred to as axes. Each joint of the segments contains a step motor that rotates and allows the robotic link to complete a specific motion of the arm 111. Upon actuation of the robotic arm 111 by the microcontroller, the motor drives the movement of the clamp to provide movement to the sensing module 112 in the receptacle 112 to check parameters including viscosity and pH of the prepared sunscreen.

[0031] The sensing module 112 includes a viscosity sensor and pH sensor to check parameters including viscosity and pH of the prepared sunscreen. The viscosity sensor works by measuring the resistance of the prepared sunscreen to flow under specific conditions. The sensor typically uses a rotating spindle immersed in the solution. As the sunscreen flows around the spindle or element, the sensor detects the resistance or changes in vibration frequency, which correlates to viscosity. The sensor's data is processed by the microcontroller to check viscosity of the prepared sunscreen.

[0032] The pH sensor measures the acidity or alkalinity of the prepared sunscreen by detecting the hydrogen ion concentration in the prepared sunscreen. The sensor consists of a probe 105 with a glass electrode that interacts with the sunscreen's liquid, generating an electrical potential proportional to the pH level. This potential is then converted into a readable pH value by the microcontroller to check pH of the prepared sunscreen and accordingly directs actuation of the nozzles 107 and spouts 110 to formulate a required nature of the sunscreen.

[0033] The inside of the body 101 is designed with a tray 115 layered with a hydrogel, serving as a substrate onto which the prepared sunscreen is dispensed; the hydrogel absorbs and interacts with the sunscreen, allowing for the monitoring of changes such as texture, viscosity, and absorption rate. These changes in the hydrogel's properties, such as swelling, elasticity, or moisture retention, reveal key characteristics of the sunscreen, such as its spreadability, skin compatibility, and long-lasting effects, aiding in the testing and evaluation of the sunscreen’s performance, stability, and overall efficacy for skin protection.

[0034] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is preferably a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0035] The present invention works best in the following manner, where the body 101 developed to be positioned on the ground surface for formulation of sunscreen. Upon activation of the device by the user, the microcontroller generates the command to activate the artificial intelligence-based imaging unit 103 to determine phenotypic condition of the user’s skin including acne or pores. In response to the determined phenotypic condition of the user’s skin, the motorized gripper 104 is actuated by the microcontroller for monitoring skin type of the user via the integrated contact probe 105. Plurality of chambers 106 with the electronically controlled nozzle 107 are actuated by the microcontroller to dispense the optimum amount of the evaluated ingredients from the chambers 106 in the container 108. Multiple electronically controlled spouts 110 are then actuated by the microcontroller to dispense the required chemical agent stored in the box 109 in the container 108 to prevent any allergic reaction on the user’s skin as per the user’s medical condition.

[0036] In continuation, upon dispensing of the crystalline ingredient in the receptacle 112, the motorized grinder 113 is actuated by the microcontroller to grind the ingredient in view of maintaining the powdered form of the ingredients. the motorized stirrer 114 is then actuated by the microcontroller to rotate at the pre-defined speed for blending the ingredients to formulate the sunscreen. Upon mixing of the ingredients, the robotic arm 111 is actuated by the microcontroller to check parameters including viscosity and pH of the prepared sunscreen via the sensing module 112 to formulate the required nature of the sunscreen.
