Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual application methods are used for eyelash compositions, then the device complexity is low, but the manufacturing precision and application accuracy deteriorate
Solution Approach 1:
The device is divided into distinct functional modules: a dispensing system with mixer and pump, an application system with heat element and extruded outlet, and intelligent control elements including sensors. This segmentation allows each module to be optimized independently for its specific function while maintaining overall system precision.
Solution Approach 2:
Manual mechanical application is replaced with an automated system that uses a pump to deliver composition, a mixer to prepare formulas, a heat element to control viscosity, and sensors with circuitry to detect positioning and control extrusion. This substitution of mechanical manual operations with automated mechanical and electronic systems significantly improves application precision.
2Measurement precision
If automated dispensing and mixing systems are implemented, then the application precision improves, but the device complexity increases
Solution Approach 1:
The device incorporates sensors (accelerometer, gyroscope, contact sensor, optical system) that provide real-time feedback on device movement, orientation, and positioning. This feedback is processed by circuitry that automatically adjusts the pump and extruded outlet to maintain precise positioning and working space definition, enabling high measurement precision through closed-loop control.
Solution Approach 2:
The intelligent control system serves multiple functions: it processes sensor data from various sensors, determines device positioning and orientation, controls the pump delivery rate, regulates the heat element temperature, and manages the mixing process. This multi-functionality consolidates what would otherwise require separate systems into a single integrated control unit, managing complexity while maintaining precision.
3Manufacturing precision
If heat elements and pumps are used for composition delivery, then the application accuracy improves, but the use of energy increases
Solution Approach 1:
The pump operates in a periodic manner, delivering composition only when needed during the application process rather than continuously. The system activates the pump based on sensor feedback and application requirements, and the heat element cycles to maintain optimal temperature without continuous high-power operation. This periodic action reduces overall energy consumption while maintaining application accuracy.
Solution Approach 2:
The system dynamically adjusts operational parameters including pump delivery rate and heat element temperature based on real-time sensor feedback and application progress. By optimizing these parameters rather than maintaining fixed high values, the system achieves high application accuracy with reduced energy consumption compared to constant maximum operation.
