Lotion application assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion dispensers lack a combination of a refillable container, a roller for skin application, and a plunger mechanism to efficiently apply lotion to the skin.
Innovation Solution
A hollow handle with a rotatably coupled roller, a conduit for fluid communication, and a plunger mechanism that urges lotion from a refillable container onto the roller for smooth skin application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lotion dispenser includes only a plunger mechanism, then lotion can be dispensed, but it cannot be applied smoothly to the skin
Solution Approach 1:
The patent combines a plunger mechanism for lotion dispensing with a roller mechanism for skin application into a single integrated device. The plunger urges lotion through a conduit onto the roller, which then applies the lotion smoothly to the skin surface, merging dispensing and application functions in one device.
2Adaptability or versatility
If a lotion dispenser uses a non-refillable container, then the structure is simple, but it cannot be refilled and must be discarded when empty
Solution Approach 1:
The patent divides the lotion dispenser into separable components: a refillable container that can be removed and replaced, and a permanent dispenser body containing the plunger and roller mechanisms. This segmentation allows the container to be refilled or replaced independently while maintaining the complex dispenser structure.
3Ease of operation
If a lotion dispenser lacks a roller mechanism, then the structure is simple, but the lotion cannot be applied evenly to the skin
Solution Approach 1:
The patent merges a plunger-based dispensing mechanism with a roller-based application mechanism. The plunger forces lotion through a conduit onto the roller, which then transfers and distributes the lotion evenly across the skin surface through its rolling motion, combining dispensing and application in one integrated system.
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
Facilitates efficient and continuous lotion application to the skin, allowing for easy refilling of the container as needed, enhancing user convenience and application efficiency.
Implementation Method 1
The plunger is urgeable into the container to urge the fluid lotion outwardly through the conduit and onto the roller

AI summary
A lotion application assembly includes a handle that is hollow and a roller that is rotatably coupled to the handle for rolling along a user's skin. A conduit is integrated into the handle and the conduit is directed toward the roller. A container is insertable into the handle, the container contains a fluid lotion and the container is in fluid communication with the conduit when the container is inserted into the handle. A cap is removably attachable to the handle and a plunger is slidably integrated into the cap. The plunger is urgeable into the container to urge the fluid lotion outwardly through the conduit and onto the roller thereby facilitating the roller to apply the fluid lotion onto the user's skin.
