Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same intensity of electric stimulation is applied during every use, then the operation is simple, but the user experience varies according to skin condition
Solution Approach 1:
The iontophoresis device dynamically adjusts the intensity of electric stimulation based on real-time detection of skin condition (such as skin impedance or moisture level). The control unit modifies output parameters to maintain optimal and uniform stimulation intensity across different uses and skin conditions, transforming a static system into an adaptive one.
Solution Approach 2:
The device incorporates a sensor to detect skin condition and feeds this information back to the control unit, which then adjusts the stimulation intensity accordingly. This closed-loop feedback mechanism ensures that the stimulation intensity remains uniform and appropriate regardless of variations in skin condition.
2Adaptability or versatility
If multiple light sources with different wavelengths are mounted, then various skin improving effects can be achieved, but the number of components and assembly complexity increases
Solution Approach 1:
The patent combines multiple light-emitting diodes with different wavelength bands into a single integrated light source assembly. This merging approach allows the device to emit multiple wavelengths (e.g., blue light for acne, red light for anti-aging) while reducing the number of separate components, simplifying assembly, and improving manufacturing efficiency.
Solution Approach 2:
The single light source is designed to perform multiple functions by emitting different wavelengths of light. This multi-functional light source can address various skin conditions (acne, wrinkles, pigmentation) simultaneously or sequentially, eliminating the need for multiple separate light sources and reducing overall device complexity.
3Adaptability or versatility
If multiple light sources with different wavelengths are mounted, then various skin improving effects can be achieved, but assembly productivity decreases
Solution Approach 1:
By integrating multiple LEDs into a single light source module, the assembly process is simplified. Instead of mounting and aligning multiple separate light sources, the integrated module can be installed as one unit, significantly improving assembly productivity while maintaining the capability to emit multiple wavelengths for various skin treatments.
