Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual application of hair coloring formulation is used, then the user can control the application process, but the coverage is uneven and the results are unpredictable
Solution Approach 1:
The device enables self-service application by providing automated oscillating motion that ensures uniform coverage without requiring advanced user technique. The mechanical oscillation system automatically distributes the formulation evenly across the scalp and hair roots, eliminating the need for manual dexterity while maintaining consistent application quality.
Solution Approach 2:
The application system incorporates dynamic oscillating nozzles that move back and forth to distribute formulation uniformly. This dynamic motion transforms the static manual application process into an automated oscillating system that consistently delivers even coverage regardless of user skill level.
2Measurement precision
If precise application to targeted areas is required, then the coverage accuracy improves, but the application time increases
Solution Approach 1:
The device employs periodic oscillating motion of the nozzles to rapidly cover targeted areas with precise formulation delivery. This periodic back-and-forth action allows the system to methodically treat specific regions like hair roots with high precision while maintaining efficient application speed through automated rhythmic movement.
3Manufacturing precision
If traditional hair coloring systems are used, then the formulation can be applied to hair, but the coverage is uneven particularly at the roots
Solution Approach 1:
The oscillating nozzle system dynamically adapts to the scalp surface contours, ensuring uniform formulation distribution across difficult-to-reach areas like hair roots. This dynamic motion allows the formulation to reach all targeted areas consistently, improving overall coverage uniformity and scalp treatment effectiveness.

AI summary
A drive shaft coupling is provided, such as a coupling used with a formula delivery appliance. The drive shaft coupling generally includes a drive gear and a driven gear, with one of the drive gear and driven gear having a biasing member to allow axial translation. The drive shaft coupling is generally configured to transfer rotation from the drive gear to the driven gear. In one aspect, the drive shaft coupling is capable of alignment and coupling of the drive gear and driven gear upon the radial sliding of the coupling from a non-engagement position to an engagement position.
