Rolling Applicator Fluid Dispensing for Uniform Surface Spreading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid applicators lack the ability to efficiently dispense fluid through nozzles dispersed across a rolling applicator, which is movable by a user to spread the fluid uniformly over a surface.
Innovation Solution
A tube coupled to a handle with a rotating applicator featuring a cavity and dispensing nozzles fluidically connected to a channel, where a pump compels fluid through the nozzles as the applicator engages the user's skin, allowing for even distribution of the fluid during a rolling motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fluid is dispensed through stationary orifices or porous material, then fluid can be applied to the user, but the fluid cannot be evenly spread over the user's surface
Solution Approach 1:
The applicator transitions from a stationary structure to a dynamic rolling structure. The applicator rotates as it moves across the user's skin, enabling even fluid distribution through the rolling motion that naturally spreads the dispensed fluid across the surface.
Solution Approach 2:
The invention combines fluid dispensing and fluid spreading functions into a single integrated applicator. The rolling applicator simultaneously dispenses fluid through its nozzles and spreads the fluid across the user's skin through its rotational motion, eliminating the need for separate application and spreading steps.
2Adaptability or versatility
If separate members are used for scrubbing or massaging, then additional functional features are provided, but the device complexity increases
Solution Approach 1:
The rolling applicator surface serves multiple functions simultaneously. It dispenses fluid through integrated nozzles, spreads the fluid through rolling motion, and provides massaging or scrubbing effects through its textured surface features, all within a single unified structure.
Solution Approach 2:
The invention merges fluid dispensing, fluid spreading, and massaging/scrubbing functions into one integrated applicator head. The rolling element incorporates nozzles for fluid delivery and surface features for mechanical stimulation, eliminating separate components.
3Quantity of substance
If fluid is forced through cavities of porous material, then fluid can be dispensed, but the fluid application is not uniform across the surface
Solution Approach 1:
Instead of using a single porous material block, the invention segments the fluid dispensing into multiple discrete nozzles distributed across the applicator surface. This segmentation allows for more controlled and uniform fluid delivery patterns as the applicator rolls across the skin.
Solution Approach 2:
The applicator uses dynamic rolling motion rather than static porous material contact. The rotation of the applicator during application ensures even distribution of fluid from multiple nozzles across the user's surface, overcoming the non-uniform dispensing limitation of porous materials.
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
Enables efficient and uniform application of fluid over a user's surface through frictional engagement, ensuring effective spreading of the fluid as the applicator rotates, enhancing user convenience and application efficiency.
Implementation Method 1
A pump is fluidically coupled to the channel and is positioned such that the pump is configured for compelling the fluid from a fluid source serially through the channel, the cavity of the applicator, and the dispensing nozzle
Implementation Method 2
The applicator is configured to rotate when the outer surface of the applicator frictionally engages a user and to spread the fluid over the user when the outer surface of the applicator frictionally engages the fluid while the fluid covers the user
