Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial cleansing devices that connect to mechanical apparatuses, such as shavers, lack axial vibration, which is believed to enhance cleansing effectiveness, whereas dedicated devices with dual motion provide better results but are not always necessary or convenient.
Innovation Solution
A device that connects to a rotational driving element, like a shaver, using a connector and oscillation generator with permanent magnets to introduce oscillation movement to a base, allowing for detachable attachment to a skin treatment element, providing both rotation and axial vibration without requiring a dedicated device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical accessory brush is connected to a shaver, then the device can function without electrical power and is simple to use, but it lacks axial vibration and provides less effective cleansing
Solution Approach 1:
The patent introduces an oscillation generator as an intermediary component between the rotational driving element and the brush. This oscillation generator converts the rotational motion into dual motion (rotation + axial vibration) through mechanical coupling, enabling the brush to achieve both rotational and oscillating movements without requiring electrical power
Solution Approach 2:
The patent changes the motion parameters by transforming single rotational motion into dual motion (rotation plus axial vibration). The oscillation generator modifies the motion state of the brush by adding axial vibration component to the rotational motion, thereby improving cleansing effectiveness while maintaining mechanical operation
2Reliability
If a dedicated facial treatment device with dual motion is used, then cleansing effectiveness is improved, but the device complexity increases and requires electrical power
Solution Approach 1:
The patent creates a universal interface that allows a standard shaver's rotational driving element to power a facial treatment brush. The mechanical coupling mechanism enables the shaver to perform multiple functions (shaving and facial cleansing) without requiring a dedicated electric facial treatment device, thereby reducing overall system complexity
Solution Approach 2:
The oscillation generator serves as a mechanical intermediary that converts rotational motion to dual motion without requiring electrical components. This mechanical approach simplifies the device by eliminating motors, batteries, and electronic controls while achieving the desired dual motion effect
3Device complexity
If a mechanical interface transmits only rotation to the brush, then the interface is simple, but axial vibration is not provided
Solution Approach 1:
The patent introduces dynamic motion transformation by allowing the brush to have both rotational and axial degrees of freedom. The oscillation generator creates dynamic coupling between the rotational driving element and the brush, enabling the brush to oscillate axially while rotating, thereby providing both rotational and axial motion capabilities
