Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beauty devices provide a limited sense of use due to the inability to dynamically vary the stimulus applied to the skin, leading to a less engaging user experience.
Innovation Solution
A beauty device with an electrode group comprising three or more electrodes, controlled by a unit that changes the selection of positive and negative electrodes at predetermined intervals, varying the current characteristics to provide a more dynamic and engaging stimulus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined combination of electrodes is used for energizing the skin, then the device structure is simple, but the sense of use for the skin is poor
Solution Approach 1:
The patent implements dynamic electrode configuration by allowing the control unit to change the combination of positive and negative electrodes over time. The electrode combination is not fixed but varies dynamically, creating different current paths through the skin at different time points, which enhances the sense of use while maintaining manageable device complexity through automated control.
Solution Approach 2:
The control unit performs periodic switching of electrode combinations at predetermined time intervals. This periodic action creates a rhythm of varying current paths through the skin, providing diverse stimulation patterns that improve the sense of use without requiring continuous complex control, as the switching follows a predetermined periodic schedule.
2Adaptability or versatility
If the same current characteristics are applied by all positive electrodes, then the control is simple, but the stimulus to the skin is limited
Solution Approach 1:
The patent applies different current characteristics to different positive electrodes based on their local positions and functions. Each positive electrode can have independently controlled current parameters (amplitude, frequency, waveform), allowing tailored stimulation patterns for different skin regions while the control unit manages the complexity of coordinating these multiple independent control channels.
Solution Approach 2:
The control unit varies current parameters (amplitude, frequency, waveform shape) for different positive electrodes to create diverse stimulation patterns. By changing these electrical parameters dynamically, the device provides varied stimuli to the skin without requiring additional hardware complexity, as the variation is achieved through software-controlled parameter adjustment.
