Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a multi-cyclone system with separate primary and secondary cyclone units is used, then fine dust and ultrafine dust separation efficiency is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines the primary cyclone unit and secondary cyclone unit into a single integrated dust collector body. The primary cyclone separates coarse dust while the secondary cyclone separates fine dust and ultrafine dust, merging multiple separation functions into one unified structure. This integration maintains high dust separation efficiency while significantly simplifying the assembly process compared to using separate cyclone units.
Solution Approach 2:
The secondary cyclone unit is nested within the primary cyclone unit structure. The dust collector body contains both cyclone systems in a nested arrangement where the secondary cyclone operates within the space defined by the primary cyclone. This nesting approach maximizes space utilization and simplifies the overall device structure while maintaining effective multi-stage dust separation.
2Device complexity
If conventional dust collectors with gaps between cyclone components are used, then device simplicity is maintained, but separation efficiency of fine dust and ultrafine dust deteriorates
Solution Approach 1:
The dust collector employs an integrated design where the cyclone components are merged into a unified structure with the dust collector body. This eliminates gaps between separate cyclone components while maintaining structural simplicity. The seamless integration ensures that fine dust and ultrafine dust are effectively separated without leakage or inefficiency caused by component gaps.
3Device complexity
If axial cyclones with integrated casings and fine dust separating members are used, then assembly complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The casing and fine dust separating member are integrated into a single axial cyclone component. This merging of parts reduces the number of separate components that need to be assembled, thereby simplifying the assembly process. The integrated design ensures precise alignment and positioning of the fine dust separating member within the cyclone structure, maintaining high manufacturing precision while reducing assembly complexity.

AI summary
The dust collector, that may be used in vacuum cleaner, includes: a primary cyclone unit separating dust from air introduced from outside the dust collector; and a secondary cyclone unit defining axial cyclone bodies separating fine dust from air introduced in an axial direction. The secondary cyclone unit includes casings having outer walls around hollow portions; and a fine dust separating member disposed on the casings to form the axial cyclones. The fine dust separating member includes vortex finders disposed in the casings; band portions enclosing an outer circumferential surface of the vortex finders at a position spaced from the vortex finders, and having a shape corresponding to the casings so as to form the axial cyclones together with the casings; and guide vanes disposed between the vortex finders and the band portions and extending in a spiral direction to induce a rotational flow of air.
