Pneumatic Pressure Dispensing System for Personalized Compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for preparing personalized compositions, such as cosmetic and pharmaceutical products, face challenges including high costs, contamination risks, inaccurate dosing, and inefficiencies due to the use of syringe drivers and single-use cartridges, which limit the number of possible formulations and lead to waste and hygiene issues.
Innovation Solution
A pneumatic-pressure-based system with multi-use cartridges and pressure changeover switches allows for precise control of active compound dispensing, using ejection nozzles with higher hydraulic resistance to ensure accurate dosing and minimize contamination, while pressure sensors monitor and adjust for optimal filling and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If syringe drivers are used to dispense active ingredients, then dosing control is achieved, but the device becomes very expensive and contamination risks increase
Solution Approach 1:
The patent replaces the mechanical syringe driver system with a pneumatic-pressure-based system. Instead of using motorized syringes to push products, the invention uses pressure generators to apply pneumatic pressure to cartridges containing active ingredients, causing the products to be dispensed through ejection nozzles. This substitution eliminates the need for expensive positive-displacement actuators while maintaining dosing control through pressure regulation and timing.
Solution Approach 2:
The patent employs pneumatic pressure as the driving force for dispensing active ingredients. Pressure generators create controlled pneumatic pressure that is applied to flexible membranes or directly to cartridges, forcing the active ingredients through ejection nozzles at controlled rates. This pneumatic system replaces the mechanical syringe mechanism, reducing cost while enabling precise control of dispensing through pressure regulation.
2Stability of the object's composition
If a mixing zone with back-pressure is used, then mixing is achieved, but product contamination and dose loss occur due to back-pressure pushing product upstream
Solution Approach 1:
The patent removes the mixing zone and back-pressure mechanism from the system. Instead of mixing products downstream in a chamber that creates back-pressure, the invention performs mixing upstream or eliminates the need for mechanical mixing by allowing passive mixing to occur after dispensing. This extraction of the mixing zone eliminates the source of contamination and dose loss caused by back-pressure forcing products upstream.
Solution Approach 2:
The patent inverts the traditional approach by dispensing active ingredients separately and allowing mixing to occur naturally after dispensing, rather than forcing mixing through back-pressure in a shared chamber. Each active ingredient is dispensed through its own ejection nozzle directly to the user, and mixing occurs passively in the air or in a simple receiving area without creating harmful back-pressure conditions.
3Object-affected harmful factors
If single-use cartridges are used, then hygiene is improved, but the number of possible formulations is limited and waste increases
Solution Approach 1:
The patent creates a universal cartridge system where a single cartridge design can hold different active ingredients. The cartridges are standardized with uniform dimensions, connection interfaces, and ejection nozzle configurations, allowing the same dispensing mechanism to work with multiple different formulations. This universality enables the system to achieve hygiene through disposable cartridges while maintaining versatility by simply changing the cartridge contents rather than the entire dispensing system.
4Measurement precision
If ejection nozzles with high hydraulic resistance are used, then dosing accuracy is improved, but the system requires higher pressure
Solution Approach 1:
The patent optimizes the hydraulic resistance parameter of the ejection nozzles to achieve the right balance between dosing accuracy and required pressure. By carefully designing the nozzle geometry (diameter, length, shape) to provide appropriate resistance, the system achieves precise metering of active ingredients without requiring excessively high pressures. The pressure generators are sized to provide sufficient pressure for the optimized nozzles while remaining practical and cost-effective.
