Solution Overview
Problem
Existing methods for applying topical compositions to keratinous surfaces, such as the skin, lack precision and control, particularly when held in inverted orientations, and often result in uneven distribution and potential skin damage due to high pressures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual methods (brush, fingers, sponge) are used to apply topical compositions, then the application process is simple, but the distribution is uneven and precision is poor
Solution Approach 1:
The patent replaces manual mechanical application methods (brush, fingers, sponge) with a pressurized deposition system that uses controlled fluid dynamics to deliver composition. The system employs a reservoir, pump, and deposition device to mechanically control composition delivery, achieving uniform and precise application while eliminating manual handling variability
Solution Approach 2:
The patent utilizes pressurized fluid delivery through a controlled hydraulic system. A pump pressurizes the composition in a reservoir and delivers it through conduits to a deposition device, enabling precise control over composition flow rate, pressure, and distribution pattern to achieve uniform application
2Productivity
If high pressure is used to dispense composition, then the composition can be applied quickly, but skin damage may occur
Solution Approach 1:
The patent employs dynamic pressure control where the pump and deposition device adjust pressure in real-time based on delivery requirements. The system maintains pressure within an optimized range that enables rapid composition delivery while incorporating sensors and control mechanisms to prevent excessive pressure that could cause skin damage
Solution Approach 2:
The patent incorporates feedback mechanisms including pressure sensors and flow sensors that monitor composition delivery in real-time. The control system adjusts pump pressure and deposition parameters based on sensor feedback to maintain optimal delivery conditions, preventing both under-application and over-pressurization that could harm skin
3Adaptability or versatility
If the device is held in inverted orientations, then user flexibility is improved, but pressure control becomes difficult
Solution Approach 1:
The patent designs the pressurized delivery system to maintain consistent pressure regardless of device orientation. The pump and pressure regulation mechanisms compensate for gravitational effects, ensuring that composition delivery pressure remains constant whether the device is held upright, inverted, or at any intermediate angle, enabling precise application in all orientations

Implementation Method 1
The expandable chamber is biased towards a deflated configuration so that, when filled with the composition the chamber expands against this bias applying pressure to the composition stored therein
Implementation Method 2
a pressure sensor generating pressure data corresponding to a pressure of the composition in the accumulator

AI summary
A device for dispensing a fluid topical composition includes a reservoir storing the composition and dispensing a pressurized flow of the composition. The device also includes an accumulator having an expandable chamber in fluidly communication with the reservoir. The chamber is biased towards a deflated configuration so that, when filled with the composition the chamber expands against this bias applying pressure to the composition stored therein. The device includes a supply valve regulating the flow of the composition from the reservoir to the accumulator, and a pressure sensor. The device further includes a processing arrangement analyzing data from the sensor to determine whether pressure in the accumulator is above a predetermined threshold and controlling the supply valve to maintain the pressure within a desired pressure range. The device also includes a deposition arrangement dispensing the composition from the accumulator under control of the processing arrangement.
