Skin Care Brush Vibration Damping for Hand Comfort
Find Innovative SolutionsGenerate Solutions
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 operating at a gentle frequency, combined 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 rigid connection to the handle, then the vibration transmission to the brush head is effective for cleansing, but the device transmits excessive vibrations to the user's hand causing discomfort
Solution Approach 1:
A vibration damper is introduced as an intermediary component between the head support platform and the handle. This damper absorbs and dissipates vibrations, preventing excessive vibration transmission to the user's hand while maintaining effective cleansing action at the brush head
Solution Approach 2:
The vibration damper is positioned in advance between the motor assembly and the handle to cushion and reduce vibrations before they reach the user's hand, providing proactive protection against excessive vibration transmission
2Productivity
If a powered skin care device uses a strong vibrating motor, then the cleansing effectiveness is improved, but the device becomes too aggressive on the skin
Solution Approach 1:
The bristles are designed with varying lengths and stiffness parameters to optimize the balance between cleansing effectiveness and gentleness on the skin, allowing the device to be effective without being overly aggressive
Solution Approach 2:
The vibration is concentrated and optimized at the brush head contact point with the skin, providing sufficient cleansing action where needed while the damper reduces excessive vibration transmission to the handle and user's hand
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a gentler cleansing experience with reduced vibration and noise transmission to the hand, ensuring comfort and effective skin care across different skin types.
Implementation Method 1
A vibration damper is provided between the head support platform including the vibratory mechanism, and the handle of the device to reduce the transmission of vibrations from the head support platform to the handle of the device such that vibrations at the handle are minimized
Implementation Method 2
the vibratory mechanism is capable of generating vibrations in a frequency of about 80 Hz to 250 Hz when power is supplied from the battery
