Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed rigid electrodes are used on the application surface, then the device structure is simple, but the electrode-skin adhesion is poor and contact is uneven
Solution Approach 1:
The patent employs springs as elastic members to transform the rigid electrode structure into a dynamic, flexible system. The springs enable the electrodes to move and adapt to skin contours, improving adhesion and contact uniformity while maintaining structural simplicity.
Solution Approach 2:
The patent changes the physical state of the electrode support from rigid to elastic by introducing springs. This parameter change allows the electrodes to deform and conform to irregular skin surfaces, significantly improving contact reliability without complex mechanisms.
2Ease of operation
If separate charging devices are used for cosmetic containers, then the charging function is independent, but the device is inconvenient to use and chargers may be misplaced
Solution Approach 1:
The patent merges the charging function directly into the cosmetic container by integrating a charging device within the container structure. This combination eliminates the need for separate charging accessories, ensuring the charger is always available and preventing misplacement, while adding minimal structural complexity.
Solution Approach 2:
The cosmetic container is designed with multi-functionality, serving both as a storage vessel and as an integrated charging station. This universal design allows the single device to perform multiple functions (storage, dispensing, and charging), improving ease of operation without requiring additional components.
3Reliability
If precise electrode positioning is attempted to ensure consistent contact, then manufacturing precision requirements increase, but assembly tolerances make reliable connection difficult
Solution Approach 1:
The patent changes the electrode support from a rigid fixed-position structure to a flexible spring-supported structure. This parameter change allows the electrodes to self-adjust to the correct positioning through elastic deformation, compensating for assembly tolerances and ensuring reliable circuit connections without requiring high manufacturing precision.
Solution Approach 2:
The springs act as beforehand cushioning elements that compensate for potential positioning errors due to manufacturing tolerances. By incorporating this elastic buffer in advance, the system ensures reliable electrode-circuit connection even when assembly variations occur, preventing connection failures.

Function Achieved in This Case
Enhances therapeutic efficiency, improves usability, and ensures consistent electrode-skin contact, eliminating the need for separate charging accessories and providing a versatile, ergonomic, and hygienic treatment experience.
Implementation Method 1
Each floating electrode is mounted within a mounting hole and supported by an elastic member such as a spring, enabling the electrode to move inward and outward relative to the applicator head
Implementation Method 2
When these electrodes contact the skin, the circuit loop is completed through the skin, enabling therapeutic microcurrent delivery
Implementation Method 3
the input electrodes are configured to engage with a pair of output electrodes of the charging device, thereby establishing electrical connection for charging of the battery
