Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a high-frequency oscillation plate is used to atomize liquid, then the liquid can be atomized into droplets, but excessive heat is generated causing overheating and potential malfunction
Solution Approach 1:
The patent replaces the high-frequency oscillation plate (mechanical vibration system) with a nozzle plate unit that uses fluid pressure and an indirect spray unit with a tapering channel structure to atomize liquid. This substitution eliminates the heat generation problem caused by high-frequency mechanical oscillations while achieving effective droplet atomization through pressure-driven flow and geometric channel design.
Solution Approach 2:
The patent changes the atomization mechanism from high-frequency mechanical oscillation to pressure-driven flow through a tapering channel structure. By adjusting parameters such as liquid pressure, channel angle (30-80 degrees), and channel geometry, the system achieves effective atomization without the excessive heat generation associated with high-frequency oscillation plates.
2Manufacturing precision
If a high-frequency oscillation plate is used to atomize liquid, then atomization can be achieved, but heat may denature additives such as essences and fragrances
Solution Approach 1:
The patent replaces the heat-generating high-frequency oscillation plate with a pressure-driven nozzle plate unit and indirect spray unit. This mechanical substitution maintains atomization capability while eliminating thermal exposure that would denature heat-sensitive additives such as essences and fragrances.
Solution Approach 2:
The patent converts the potential harm of heat generation into a benefit by designing a system that achieves atomization through pressure and geometry rather than heat. The tapering channel structure utilizes pressure-driven flow to create fine droplets, transforming what would have been a harmful thermal process into a beneficial cold atomization process that preserves additive integrity.
3Device complexity
If larger droplets are produced, then the atomization process is simpler, but the air becomes over-humidified
Solution Approach 1:
The patent segments the atomization process into two stages: a nozzle plate unit that creates initial atomized droplets, and an indirect spray unit with a tapering channel structure that further divides these droplets into finer second atomized droplets. This segmentation enables precise humidity control by producing sufficiently small droplets without requiring excessive device complexity in a single stage.
4Manufacturing precision
If the droplet inlet opening is larger than the droplet outlet opening in the tapering channel, then droplets can effectively strike and rebound to form smaller droplets, but the channel structure becomes more complex
Solution Approach 1:
The patent employs a tapering channel structure where the channel cross-section gradually changes from a larger inlet opening to a smaller outlet opening. This curved, tapered geometry naturally guides droplets through striking and rebounding actions against the channel walls, achieving effective droplet size reduction through a single integrated structure rather than multiple discrete components.

AI summary
The present invention provides an atomizing device, which comprises: a first liquid chamber to store a liquid to be atomized; a nozzle plate unit disposed on the first liquid chamber and used to spray the liquid into first atomized droplets; and an indirect spray unit disposed at a position where the first atomized droplets are sprayed to accept the first atomized droplets. The indirect spray unit comprises a channel-like structure having a droplet inlet disposed toward a position where the nozzle plate unit sprays out the first atomized droplets; and a droplet outlet disposed on one side wall of the atomizing device. The droplet inlet receives the first atomized droplets to enter the indirect spray unit. The first atomizing droplets undertake striking and rebounding repeatedly in the channel-like structure to form the second atomized droplets. The second atomized droplets are sprayed out from the droplet outlet.
