Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the cleaner is designed with conventional air passage layout, then the structure is simple, but the suction power loss is high
Solution Approach 1:
The device housing is disposed inside the cup casing, forming a nested structure where the air passage is defined between the outer cup casing and inner device housing. This nesting arrangement creates an efficient air flow path that reduces suction power loss while maintaining a compact overall structure.
Solution Approach 2:
The air passage is designed to extend along the axial direction of the cyclone separating device, utilizing the vertical dimension efficiently. This three-dimensional air passage layout optimizes airflow dynamics and reduces energy loss compared to conventional two-dimensional layouts.
2Volume of moving object
If the cleaner is designed with compact structure, then the volume and weight are reduced, but the mounting stability of negative pressure device may be compromised
Solution Approach 1:
The negative pressure device is mounted inside the device housing, which itself is nested within the cup casing. This nested mounting approach reduces the overall volume while maintaining stable positioning through multiple structural levels.
Solution Approach 2:
The bracket structure includes an upholding portion that replicates the mounting function within the constrained space of the compact housing, ensuring stable negative pressure device attachment despite the reduced overall size.
3Reliability
If the negative pressure device is firmly fixed, then the mounting stability is high, but the vibration generated during operation increases
Solution Approach 1:
A vibration absorbing member is provided between the bracket and the negative pressure device to cushion vibrations before they propagate to the housing structure. This beforehand cushioning reduces harmful vibrations while maintaining mounting stability.
Solution Approach 2:
The vibration absorbing member acts as an intermediary element between the negative pressure device and the bracket, decoupling the rigid connection and allowing vibration isolation while maintaining functional mounting stability.
