Solution Overview
Problem
Existing body cleansers lack versatility and effectiveness in managing skin texture and dead skin cells, particularly for specific areas like elbows and heels, and often fail to provide optimal cleansing with ultrasonic waves and vibrations.
Innovation Solution
A body cleanser design featuring a rotatable ultrasonic head with interchangeable brush units, including a silicone brush, regular bristle brush, and glass brush, which apply vibrations and ultrasonic waves to manage skin texture and dead skin cells, with a controller to optimize operation based on the mounted brush unit, and sealing members to minimize moisture penetration and protect internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate cleansing devices are used for different skin areas and needs, then specific cleansing requirements are met, but device complexity and user burden increase
Solution Approach 1:
The patent implements a universal cleanser head that can perform multiple cleansing functions by integrating different brush units (silicone brush for gentle cleansing, bristle brush for deep cleaning, glass brush for exfoliation) and ultrasonic vibration capability into a single replaceable module. This allows one base device to serve multiple skin care needs through brush unit replacement, resolving the contradiction between versatility and device complexity.
Solution Approach 2:
The cleanser is divided into modular components: a base device housing containing the ultrasonic vibrator and battery, and interchangeable brush units with different materials and functions. This segmentation allows the versatile functionality to be achieved through simple module replacement rather than integrating all functions into a single complex unit, thus maintaining ease of use while providing multiple cleansing options.
2Adaptability or versatility
If brush units are added to provide different cleansing functions, then adaptability improves, but the risk of moisture penetration and component damage increases
Solution Approach 1:
The patent employs sealing members including gaskets and waterproof films at the interface between the brush unit and base device housing. These flexible sealing elements create a waterproof barrier that prevents moisture from penetrating into the internal components (ultrasonic vibrator, battery) while allowing for the replacement of different brush units, thus maintaining both versatility and reliability.
3Reliability
If ultrasonic vibration and rotation are combined for enhanced cleansing, then cleansing effectiveness improves, but device complexity and energy consumption increase
Solution Approach 1:
The patent combines ultrasonic vibration and rotational motion into a single integrated cleansing action. The ultrasonic vibrator is mounted on the brush unit or base device housing such that its vibrations are transmitted through the brush bristles during rotation, creating a synergistic effect where both mechanisms work together simultaneously rather than as separate systems, thus improving cleansing effectiveness while limiting complexity growth.
4Adaptability or versatility
If multiple brush units with magnets are added for identification, then adaptability improves, but manufacturing complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical identification systems with a magnetic field-based detection system. Magnets are embedded in the brush units, and a sensor in the base device housing detects their presence and position to automatically identify which brush unit is installed. This substitution of mechanical complexity with electromagnetic sensing simplifies the manufacturing process while enabling versatile brush unit identification and functionality selection.
