Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid is supplied from multiple directions to the atomizing needle, then atomization performance is improved, but the structure becomes more complex and liquid supply paths may interfere with each other
Solution Approach 1:
The liquid supply system is segmented into multiple independent supply paths, each with its own liquid supply port positioned at different locations (front surface, rear surface, side surfaces) of the atomizing needle. This segmentation allows liquid to be supplied from multiple directions simultaneously, improving atomization performance while maintaining structural clarity through distinct, non-interfering supply paths
Solution Approach 2:
The liquid supply ports are distributed across multiple spatial dimensions (front surface, rear surface, side surfaces) of the atomizing needle rather than concentrating all supply paths in a single plane. This three-dimensional distribution of supply ports enables multi-directional liquid supply while preventing path interference and simplifying the overall structure
2Manufacturing precision
If atomizing needle diameter is reduced to improve atomization, then atomization performance improves, but manufacturing precision requirements increase and clogging risk increases
Solution Approach 1:
The liquid supply is segmented into multiple paths that converge at the atomizing needle tip. This segmentation allows the use of a relatively larger diameter atomizing needle while maintaining effective atomization performance, as the multiple liquid streams work together to achieve fine droplet formation without requiring an excessively small needle diameter that would be prone to clogging
Solution Approach 2:
Multiple liquid supply paths are merged at the atomizing needle tip, where liquid from front, rear, and side surfaces combines to achieve effective atomization. This merging allows the system to use a larger diameter needle for reliability while still achieving fine atomization through the combined effect of multiple liquid streams
3Manufacturing precision
If electrostatic charge is applied to improve atomization uniformity, then atomization uniformity improves, but energy consumption increases and control complexity increases
Solution Approach 1:
The system utilizes the natural electrostatic charge that already exists in the liquid to be atomized, rather than requiring an external electrostatic charging mechanism. The liquid's inherent electrostatic properties are harnessed to achieve uniform atomization, eliminating the need for additional energy-consuming electrostatic generation equipment while maintaining atomization uniformity
