Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional dust cup design is used, then the structure is simple, but suction power loss is high and energy consumption is high
Solution Approach 1:
The patent implements nesting by placing the air exhaust passage inside the dust removal chamber, and further nesting the negative pressure device within the device housing that is itself located within the cup casing. This multi-level nesting structure reduces the overall device volume and shortens air passage length, thereby reducing suction power loss while maintaining functional complexity at an acceptable level.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by arranging the air exhaust port at the opening of the cup casing, positioning the device housing with tubular structure, and configuring the negative pressure device to create radial airflow patterns. This dimensional optimization shortens the air passage length and reduces resistance, addressing the energy loss problem without excessive structural complexity.
2Loss of energy
If the air passage length is reduced, then suction power loss decreases, but the device volume must be compacted
Solution Approach 1:
The patent places the air exhaust passage within the dust removal chamber, and the negative pressure device within the device housing that is itself within the cup casing. This nesting arrangement achieves compact volume while maintaining short air passage length, as each component utilizes the internal space of the previous component rather than requiring additional external space.
Solution Approach 2:
The patent merges the air exhaust function with the dust removal chamber structure, and combines the negative pressure device with the device housing. This integration eliminates the need for separate external passages and housings, achieving both compact volume and short air passages simultaneously.
