Solution Overview
Problem
Existing dust collecting equipment struggles to seamlessly switch between automatic and manual cleaning modes without complex configuration changes, as it requires altering the cleaning nozzle, flow path, and various structures.
Innovation Solution
The equipment incorporates a flow path blocking member that reciprocates between positions to cover either the first or second suction port, allowing easy switching between modes by blocking the appropriate suction port for each cleaning method, and includes a lever, elastic member, and actuator for automatic movement based on nozzle coupling detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cleaner is designed to accomplish both automatic cleaning and manual cleaning, then the versatility of the cleaner is improved, but the device complexity increases due to required changes in cleaning nozzle, flow path, and various structures
Solution Approach 1:
The flow path is segmented into multiple independent channels, each with its own suction port (first suction port for automatic cleaning, second suction port for manual cleaning). The flow path blocking member divides the flow path into a first flow path and a second flow path, allowing independent control of air flow for each cleaning mode without requiring complex reconfiguration of the entire system.
Solution Approach 2:
The flow path blocking member is pre-positioned to automatically block the inappropriate suction port based on the detected cleaning mode. When the cleaning nozzle is coupled or decoupled, the blocking member proactively seals the corresponding suction port before air flow can occur, preventing interference between modes and eliminating the need for complex post-coupling adjustments.
2Ease of operation
If the cleaning nozzle is coupled for manual cleaning, then the manual cleaning function is enabled, but the automatic cleaning suction port may be interfered with or air may flow into the wrong port
Solution Approach 1:
The flow path blocking member acts as an intermediary element between the two suction ports. When the cleaning nozzle is coupled for manual cleaning, the blocking member is positioned to seal the first suction port, preventing air from flowing into it. This intermediary mechanism ensures that air flow is directed only through the intended second suction port, maintaining system reliability and preventing interference between modes.
3Productivity
If the cleaner main body is equipped for automatic cleaning with a fixed cleaning nozzle, then the automatic cleaning performance is optimized, but the manual cleaning capability requires additional structural changes
Solution Approach 1:
The dust collecting equipment is designed with universal functionality to handle both automatic and manual cleaning modes through a single integrated structure. The cleaner main body incorporates both a first suction port for automatic cleaning and a second suction port for manual cleaning, with the flow path blocking member enabling seamless switching between modes without requiring separate structural configurations for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient switching between automatic and manual cleaning without changing configurations, maintaining sealing integrity and preventing interference between modes, allowing users to easily transition between cleaning methods.
Implementation Method 1
a flow path blocking member that selectively covers the first suction port and the second suction port
Implementation Method 2
when the suction unit generates a suction force by a driving force of an electric motor, the cleaning nozzle sucks foreign matter including dust on the surface to be cleaned

AI summary
A cleaner includes a dust separation unit which separates dust from sucked air; a dust container which stores the dust separated by the dust separation unit; a first suction port through which an external air is sucked into the dust separation unit; a second suction port through which the external air is sucked into the dust separation unit; a discharge port through which air inside the dust separation unit is discharged; and a flow path blocking member which selectively covers the first suction port and the second suction port.
