Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a central focusing type ultrasonic dispersion device is used, then nanoparticles can be dispersed, but the dispersion process requires considerable time which reduces efficiency
Solution Approach 1:
The patent divides the single central ultrasonic vibrator into multiple ultrasonic vibrators arranged in an array. Each vibrator operates independently to disperse nanoparticles in different regions simultaneously, converting a sequential single-point dispersion process into a parallel multi-point process, thereby significantly reducing total dispersion time while maintaining uniformity
Solution Approach 2:
The patent transitions from a single central focusing point (0D/1D) to a two-dimensional array of ultrasonic vibrators. This spatial expansion allows ultrasonic energy to be distributed across a broader area, enabling simultaneous dispersion of large quantities of nanoparticles across the entire fluid path cross-section, thus improving both efficiency and capacity
2Manufacturing precision
If the focusing-type method is used, then a more uniform dispersion effect can be obtained, but it is difficult to disperse nano-powder in large quantities
Solution Approach 1:
The patent segments the dispersion function across multiple ultrasonic vibrators arranged in an array, with each vibrator handling a specific region. This segmentation allows the system to process large quantities of nanoparticles by distributing the workload across multiple units, effectively scaling up the dispersion capacity while each unit maintains its focusing capability for uniformity
Solution Approach 2:
The array of ultrasonic vibrators creates multiple focusing points that collectively cover the entire fluid path. Each vibrator maintains its focusing function for uniform dispersion, while the collective array provides the capacity to handle large quantities. The system thus achieves both individual precision and collective capacity
