Solution Overview
Problem
Existing facial cleansing devices that use mechanical power from shavers only provide rotational motion, lacking the axial vibration that enhances cleansing and oil control, making them less effective compared to dedicated dual-motion devices.
Innovation Solution
A device that connects to a rotational driving element, such as a shaver, using a connector and oscillation generator with permanent magnets to introduce an oscillation movement parallel to the axis of rotation, providing both rotational and axial vibrations without requiring electrical power or complex systems, thus enhancing facial cleansing efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mechanical accessory connects to a shaver using only a rotational interface, then the accessory can function without electrical power, but it cannot provide axial vibration which reduces cleansing effectiveness
Solution Approach 1:
The accessory is divided into separate functional components: a rotational coupling mechanism that interfaces with the shaver's rotating shaft, and an oscillation generator with permanent magnets that converts rotational motion into axial oscillation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity.
Solution Approach 2:
The oscillation generator uses permanent magnets arranged to create mechanical vibration through their magnetic fields. As the rotational driving element turns, it actuates the magnets to produce axial oscillation of the treatment element, adding the vibration component necessary for effective cleansing without requiring electrical power.
2Reliability
If a dedicated dual-motion facial treatment device is used, then axial vibration and rotation are provided for effective cleansing, but the device complexity and cost increase
Solution Approach 1:
The accessory utilizes the shaver's existing rotational power source to drive its own oscillation mechanism. The permanent magnets in the oscillation generator are actuated by the rotational motion itself, creating a self-sustaining system where the shaver's motor provides both rotation and, through the magnetic interaction, axial oscillation without requiring a separate power source.
Solution Approach 2:
Instead of using a complex electrical oscillation motor or solenoid to generate axial vibration, the invention substitutes a purely mechanical oscillation generator using permanent magnets. This mechanical approach converts the shaver's rotational output directly into axial oscillation through magnetic coupling, eliminating the need for additional electrical components.
3Reliability
If an oscillation generator with permanent magnets is added to provide axial vibration, then dual-motion cleansing is achieved, but the device structure becomes more complex
Solution Approach 1:
The oscillation generator is integrated into the treatment element housing, merging the oscillation mechanism with the structural components of the accessory. The permanent magnets are positioned within the existing housing structure, and the oscillation motion is directly transmitted to the treatment element, eliminating the need for separate oscillation mechanisms or additional moving parts.
