Foot lotion application device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion application devices are cumbersome and difficult to use, especially for individuals with limited mobility, as they require bending or straining to apply lotions and ointments to the feet, leading to inefficiency and potential skin damage.
Innovation Solution
A lotion application device with a base component that has an open cavity for inserting a foot, featuring an electrically powered brush with spinning brush heads operated via a remote control, and a built-in dispenser for lotion or ointment, allowing for comfortable and efficient application without bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person manually applies lotion to their feet using traditional methods, then they can apply the product directly, but they must bend down or bring their foot up towards their hands which is difficult and uncomfortable
Solution Approach 1:
The patent introduces an intermediary device (lotion application device with rotating brush) between the user and the feet. The device includes a base with an open cavity for inserting the foot, a motor-driven rotating brush mechanism, and a lotion reservoir with dispensing system. This intermediary tool applies the lotion automatically through the rotating brush contact with the foot, eliminating the need for the user to manually bend or position their foot awkwardly.
2Ease of operation
If individuals with limited mobility use traditional lotion application methods, then they can attempt to apply product, but they experience even greater difficulties and potential skin damage from untreated dry skin
Solution Approach 1:
The device enables self-service application of lotion for users with limited mobility. The foot is inserted into the base cavity, and the user can control the rotating brush through a simple interface (such as a button or switch). The automated rotating brush mechanism performs the application task that would otherwise require complex manual manipulation, allowing users with mobility limitations to independently treat their own feet and prevent skin damage.
3Productivity
If a device stores lotion within itself and uses automated application, then application efficiency increases, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated device: the lotion reservoir, motor mechanism, rotating brush, and control system are all combined in one unit. The base component houses both the lotion storage chamber and the motor-driven brush assembly. This consolidation allows automated, efficient lotion application while keeping the device as a single manageable unit rather than multiple separate components.
Solution Approach 2:
The device performs multiple functions within a single system: it stores lotion, dispenses lotion, applies lotion through mechanical rotation, and can be controlled by the user. The rotating brush serves both as a mechanical agitator for the lotion and as the application interface for the foot. This multi-functionality increases productivity while managing complexity through functional integration.

AI summary
A lotion application device is used for applying creams or lotions on difficult-to-reach places on the body, like the feet. The lotion application device comprises a base component that is configured with an open cavity for a user to insert at least one foot. Within the open cavity of the base component, an electrically powered brush with two spinning brush heads is positioned. The electrically powered brush is operated via a remote control. Further, lotion or ointment is stored within the base component and dispensed onto a user's feet and ankles, as needed. Once a person places their foot into the open cavity of the base component, he/she can activate the device with the remote control and utilize the gentle scrubbing brush heads to evenly distribute lotion to treat dry and cracked skin on the feet.
