Formula Delivery Venting Assembly for Stable Hair Treatment Mix Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair and scalp treatment systems waste formulation due to gas buildup in sealed containers, affecting the mix ratio and efficiency of treatment applications.
Innovation Solution
A formulation delivery appliance with a degassing feature that vents gases from consumable assemblies when mounted to a delivery device, maintaining the desired mix ratio without wasting formulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealed containers are used to store formulation, then formulation protection from contamination is improved, but gas buildup occurs affecting mix ratio and causing formulation waste
Solution Approach 1:
The patent extracts the gas phase from the sealed container system by providing a dedicated vent aperture that allows gas to escape while the formulation remains contained. The engagement element's vent aperture is positioned to vent gas from the container headspace without allowing formulation to leak, effectively separating the gas removal function from the formulation containment function.
Solution Approach 2:
The vent aperture acts as an intermediary pathway that mediates between the sealed container environment and the external atmosphere. It provides a controlled interface where gas can pass through while formulation is prevented from escaping, resolving the contradiction between maintaining seal integrity and allowing gas release.
2Productivity
If vent aperture is provided in engagement element, then gas evacuation is improved, but sealing reliability may be compromised
Solution Approach 1:
The patent applies local quality by providing sealing members at specific critical locations where formulation contact occurs, while the vent aperture remains open in non-critical areas. The sealing members are positioned to seal the interface between the container and engagement element, ensuring formulation containment while allowing gas to escape through the vent aperture.
Solution Approach 2:
The sealing system is segmented into multiple sealing members located at different positions. This segmentation allows the system to provide reliable sealing where needed (at the formulation interface) while maintaining open pathways (vent aperture) where gas evacuation is required, resolving the contradiction between sealing and venting functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The appliance effectively evacuates gases from sealed containers, ensuring the correct mix ratio of formulations and preventing waste, enhancing the efficiency and effectiveness of hair and scalp treatments.
Implementation Method 1
the engagement element ruptures the membrane as the container is mounted to the engagement element, wherein piercing the membrane changes the container from a sealed condition to an unsealed condition
Implementation Method 2
A vent aperture is formed in the engagement element and provides fluid communication between the channel and an area outside of the engagement element when the container is disengaged from the engagement element
Implementation Method 3
the sealing member seals the vent aperture when the container is mounted to the engagement element

AI summary
A formulation delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair. The appliance may include a container having an aperture and being configured to retain a volume of formulation. The formulation delivery appliance may further include an elongate engagement element having a channel extending therethrough and being configured to be at least partially received by the aperture of the container when the container is mounted to the engagement element. A vent aperture is formed in the engagement element and provides fluid communication between the channel and an area outside of the engagement element when the container is disengaged from the engagement element. The vent aperture is sealed, and the channel receives a flow of formulation from the container when the container is mounted to the engagement element.
