Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing adhesive application methods are used, then manufacturing process is simple, but manufacturing cost is high and time consumption is long
Solution Approach 1:
The patent employs a rotation arm that rotates to move the nozzle along a circular arc path, transforming a static application method into a dynamic one. This rotational movement enables the nozzle to efficiently traverse the curved adhesive portion of the eyelash support member, improving application speed and precision without requiring a complex multi-axis positioning system
Solution Approach 2:
The patent utilizes a circular arc-shaped moving path for the nozzle, which matches the curved geometry of the adhesive portion on the eyelash support member. This curved trajectory allows the nozzle to maintain optimal spacing and angle throughout the application process, ensuring uniform adhesive distribution while simplifying the motion control mechanism compared to straight-line or multi-directional approaches
2Manufacturing precision
If adhesive agent is applied manually, then device complexity is low, but manufacturing precision and bonding strength are insufficient
Solution Approach 1:
The patent replaces manual mechanical application with an automated nozzle system driven by a rotation arm mechanism. The nozzle is precisely positioned and moved along a predetermined circular arc path, eliminating the imprecision of manual application while avoiding the complexity of computer-controlled robotic systems. The mechanical rotation provides consistent, repeatable positioning
Solution Approach 2:
The rotation arm mechanism automatically positions and moves the nozzle along the adhesive portion without requiring external intervention or complex control systems. The system self-regulates the application process through the inherent rotational motion, maintaining consistent spacing and angle while applying adhesive uniformly across the curved surface
3Productivity
If adhesive agent is applied quickly, then productivity is improved, but application precision and bonding strength may deteriorate
Solution Approach 1:
The rotation arm provides continuous rotational motion, enabling the nozzle to apply adhesive continuously along the entire adhesive portion without stopping or repositioning. This continuous action maintains high productivity while ensuring uniform adhesive distribution, as the nozzle remains in constant motion at a controlled speed, preventing both under-application and over-application that would compromise bonding strength
