Solution Overview
Problem
Existing powered skin care devices are too aggressive and transmit excessive vibrations to the user's hand, making them uncomfortable and potentially harsh on the skin.
Innovation Solution
A powered skin care device with a vibration damper and soft bristles, featuring a resilient collar to reduce vibration transmission and a motorized vibratory mechanism generating gentle frequencies, along with a brush head design that differentiates bristle length and stiffness for various skin types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a powered skin care device uses a vibrating motor with brush head for skin cleansing, then skin cleansing function is provided, but the device transmits excessive vibrations to the user's hand and may be too aggressive for the skin
Solution Approach 1:
A vibration damper is introduced as an intermediary component between the vibrating motor and the handle. This damper absorbs and dissipates excessive vibrations before they reach the user's hand, while still allowing the brush head to effectively cleanse the skin. The damper acts as a mediator that filters harmful vibrations while preserving the useful cleansing function.
Solution Approach 2:
The vibrating motor is designed to operate at specific frequency and amplitude parameters that provide effective skin cleansing while minimizing uncomfortable vibrations. By carefully controlling the vibration parameters (frequency, amplitude, duration), the device achieves gentle yet effective cleansing without transmitting excessive vibrations to the user's hand.
2Productivity
If the vibrating motor operates at higher frequency for effective cleansing, then skin cleansing effectiveness is improved, but vibration transmission to the hand increases making it uncomfortable
Solution Approach 1:
The vibration damper serves as a selective filter that allows effective cleansing vibrations at the brush head while blocking and dissipating excessive vibrations that would cause discomfort to the user's hand. This intermediary component enables the system to maintain high productivity at the working end while protecting the user from harmful vibrations.
Solution Approach 2:
Different parts of the device have different vibration characteristics optimized for their specific functions. The brush head maintains high vibration amplitude for effective skin cleansing, while the handle and motor housing are designed with vibration-damping properties to minimize transmission to the user's hand. This local optimization of vibration quality allows both effective cleansing and user comfort.

AI summary
A powered skin care device is provided with a vibrating motor that produces vibrations in a relatively gentle frequency and has a removable brush head that includes at least two types of bristles. A first group of bristles is for more gentle cleansing and a second group of bristles is for more aggressive cleansing.
