Dual-Rotation Cleansing Brush for Friction-Enhanced Bubble Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face washing devices lack efficient bubble generation, often requiring manual effort and leading to uneven cleansing, potential bacterial infection, and waste of cleansing products due to asymmetrical force transmission and splash issues.
Innovation Solution
A cleansing device with inner and outer parts that rotate in different directions, featuring contact points and receptors to increase friction and bubble generation, while the outer part is designed to prevent bubble splashing with a compact brush structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a brush device rotates in one direction or vibrates to perform cleansing, then the cleansing operation is performed according to user's motion, but asymmetrical force is transmitted to the face having symmetrical muscle arrangement and various types of stimulation cannot be applied to the skin
Solution Approach 1:
The brush device employs dual rotation directions and vibration modes that can be dynamically switched. The rotating member can rotate in first and second directions, and the vibrating member can vibrate in different directions, allowing the device to adapt to different cleansing needs and apply various stimulation types to symmetrical facial muscles.
Solution Approach 2:
The device utilizes periodic vibration and alternating rotation directions to provide rhythmic stimulation to the skin. The vibrating member vibrates periodically in different directions, and the rotating member alternates between first and second directions, creating periodic action that enhances cleansing effectiveness and skin stimulation.
2Productivity
If a product rotated in one direction or operated by strong vibration is used, then cleansing operation is performed, but the cleansing product is splashed out causing inconvenience and may enter sensitive parts such as eyes
Solution Approach 1:
The device dynamically adjusts rotation direction and vibration patterns to control product movement. By rotating in alternating directions and vibrating in controlled patterns, the device prevents excessive centrifugal force that would cause splashing, while still maintaining effective cleansing action.
Solution Approach 2:
The brush head design incorporates asymmetrical elements where the vibrating member extends in a specific direction relative to the rotating member. This asymmetrical configuration helps contain the cleansing product during operation and prevents it from splashing outward, particularly protecting sensitive areas like eyes.
3Strength
If a commercially-available cleansing device is used, then cleansing power is provided, but the cleansing product is caught by the brush so that bubbles cannot be generated and consumers must make bubbles with hands which is inconvenient
Solution Approach 1:
The device preliminarily generates bubbles by rotating the rotating member and vibrating the vibrating member before the cleansing operation. This preliminary bubble generation action occurs within the brush head structure, creating bubbles that are then applied to the skin during cleansing, eliminating the need for manual bubble making.
Solution Approach 2:
The brush device performs multiple functions: it rotates to provide mechanical cleansing, vibrates to enhance stimulation and bubble generation, and simultaneously creates and applies bubbles to the skin. This multi-functionality integrates bubble generation into the main device, making the overall process more convenient.
4Quantity of substance
If a separate bubble generating device is purchased to increase bubble generating force, then bubble generation is improved, but financial burdens associated with consumer's purchase are increased
Solution Approach 1:
The invention merges the bubble generation function with the cleansing brush device. The rotating member and vibrating member work together within a single device to generate bubbles, combining what would traditionally require separate devices into one integrated unit, thereby reducing financial burden and simplifying the system.
Solution Approach 2:
The single brush device performs both cleansing and bubble generation functions. The rotating member provides mechanical action for cleansing while also creating bubbles through rotation and vibration, making one device serve multiple purposes and eliminating the need for separate bubble generating devices.
5Quantity of substance
If an existing method mixes air and cleansing solution through a cleansing net, then bubbles are generated, but it is difficult to generate bubbles containing delicate or homogeneous air and air bubbles may be easily lost
Solution Approach 1:
The device uses dynamic rotation and vibration actions to generate bubbles. The rotating member rotates at controlled speeds and the vibrating member provides rhythmic motion, creating delicate and homogeneous bubbles through controlled mechanical action rather than simple mixing through a net.
Solution Approach 2:
The vibrating member generates bubbles through mechanical vibration rather than simple air mixing. This vibration method creates more delicate and homogeneous bubbles by applying rhythmic mechanical energy to the cleansing product and air mixture, preventing bubble coalescence and loss.

Function Achieved in This Case
Enhances bubble generation force for efficient cleaning, reduces skin irritation, and minimizes product waste by ensuring bubbles are contained and effectively applied.
Implementation Method 1
force for mixing a cleansing product, air, and water may be increased by rotational friction while the inner cleansing part and the outer cleansing part are rotated, thus generating a bubble

AI summary
A cleansing device is proposed. The cleansing device may include an inner cleansing part coming into close contact with a cleansing target; an outer cleansing part provided outside the inner cleansing part; and a rotating part configured to rotate the inner cleansing part and the outer cleansing part relative to each other. The inner cleansing part and the outer cleansing part have at least one contact point.
