Fluid Dispensing Apparatus with POREX Wicking Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid container designs for cosmetics and oil-based products face issues with inconsistent and messy dispensing, leading to waste and clogging, as they fail to control the dosage effectively, causing consumer inconvenience and increased costs due to liability and packaging inefficiencies.
Innovation Solution
The development of fluid dispensing apparatuses with specific structures and materials, such as POREX fluid communication materials, that resist fluid migration and allow controlled dispensing by threshold pressure, enabling clean and regular application without excessive dripping, even when the container is inverted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard package options with dropper are used for oil-based products, then fluid can be dispensed, but fluid migration occurs to and around the package outskirts causing mess and clogging
Solution Approach 1:
The patent employs a porous wicking material within the dispensing apparatus that selectively absorbs and transports oil-based fluid through capillary action. The porous structure controls fluid flow paths, preventing migration to package outskirts while enabling controlled dispensing through the applicator tip.
Solution Approach 2:
The patent introduces a wicking material as an intermediary between the fluid reservoir and the applicator. This intermediary component manages fluid transport, preventing direct contact and uncontrolled migration of oil-based products to areas where they would cause mess or clogging.
2Loss of substance
If insufficient dosage of fluid is dispensed, then product waste is reduced, but consumer needs are not met
Solution Approach 1:
The dispensing apparatus uses a squeezable or collapsible reservoir design that allows dynamic control of fluid dispensing. As the consumer applies pressure by squeezing, the reservoir deforms and controls fluid flow rate, enabling precise dosage control that matches consumer needs while minimizing waste.
Solution Approach 2:
The patent incorporates a design where the consumer can visually observe fluid transfer to the applicator and adjust squeezing pressure accordingly. This feedback mechanism enables the consumer to control the dosage precisely, dispensing only the needed amount and reducing product waste.
3Quantity of substance
If excess dosage of fluid is dispensed, then consumer needs are met, but clean-up problems and clogging occur
Solution Approach 1:
The porous wicking material controls the rate and amount of fluid transfer to the applicator, preventing excess fluid from reaching areas where it would cause clogging or mess. The capillary action in the porous material ensures only the necessary dosage is transported.
Solution Approach 2:
The patent extracts the excess fluid from the system by designing the wicking material and applicator interface to accept only the required dosage. Any additional fluid remains in the reservoir, effectively removing the harmful excess before it can cause clogging or mess.
4Ease of operation
If fluid container is held inverted, then ease of application is improved, but excessive dripping occurs
Solution Approach 1:
The porous wicking material maintains controlled capillary flow even when the container is inverted. The capillary forces in the porous structure counteract gravity, preventing uncontrolled dripping while still allowing fluid to reach the applicator tip for convenient application.
Solution Approach 2:
The wicking material is pre-positioned to intercept and control fluid flow before it can drip excessively. The material's structure is designed in advance to maintain proper fluid management orientation-independent, preventing dripping issues before they occur during inverted use.
