Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is introduced from the suction port to the side part of the dust collecting apparatus to generate rotating airflow, then dust separation is achieved, but flow resistance increases and separate air pipes are required
Solution Approach 1:
The suction port and air introduction function are merged into a single integrated structure. The suction port is positioned to directly communicate with the cyclone chamber, eliminating the need for separate air pipes. The side wall of the suction port serves dual purposes: as the air introduction passage and as part of the cyclone chamber structure, thereby reducing device complexity while maintaining dust separation efficiency.
2Ease of operation
If a separate air pipe is disposed to guide air into the cyclone chamber, then airflow control is improved, but the structure becomes more complex
Solution Approach 1:
The suction port structure performs multiple functions simultaneously: it serves as the air intake port, the air introduction passage, and part of the cyclone chamber wall. This multi-functional design eliminates the need for separate air pipes while maintaining effective airflow control into the cyclone chamber, thereby simplifying the internal structure without compromising operational control.
3Ease of manufacture
If the dust collecting apparatus is designed with a fixed structure, then manufacturing is simplified, but opening and closing for dust collection becomes difficult
Solution Approach 1:
The dust collecting apparatus is segmented into a main body and a detachable dust collection chamber. The dust collection chamber can be easily removed and attached, providing convenient access for dust collection while maintaining a simple overall structure. This modular design allows the main body to remain structurally simple for easy manufacturing, while the detachable chamber enables easy operation for dust collection.
4Device complexity
If the cyclone unit configuration is simplified, then device complexity is reduced, but flow resistance may increase
Solution Approach 1:
The cyclone chamber is designed with a curved, spherical-like shape that naturally guides airflow in a rotating pattern. This curved geometry creates efficient rotating airflow for dust separation without requiring complex internal structures or additional components. The smooth curved surfaces minimize turbulence and flow resistance, reducing energy loss while maintaining a simple cyclone unit configuration.

AI summary
A cyclone dust collecting apparatus and a cleaner having the same include a grille unit including an introduction pipe communicating with the suction port and adapted to guide the air into the main cyclone chamber, and a grille body detachably provided to the introduction pipe and allowing the air to be discharged from the main cyclone chamber after dust particles in the air having a size greater than or equal to a certain size is filtered out. With this configuration, the spatial utilization of the cyclone structure may be facilitated, and visualization of the dust collection chamber may allow a user to gain satisfaction from cleaning operation.
