Solution Overview
Problem
Conventional vacuum cleaners face issues with residual dust in the dust bin, leading to reduced suction force, offensive odors, and inconvenience in emptying, particularly with strands of hair getting trapped and requiring manual removal.
Innovation Solution
A cleaner system with a cleaner station that includes a suction flow path and a dust collecting motor, where the cleaner is coupled to the station, allowing for automatic collection of dust and strands of hair without additional communication modules, using a pulse signal to control the suction motor and door for efficient dust management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the cleaner uses a small capacity dust bin to maximize portability and reduce weight, then the cleaner becomes more portable and lighter, but the user must empty the dust bin frequently which causes inconvenience and health issues
Solution Approach 1:
The cleaner station automatically empties the dust bin using a dust discharge motor and suction flow path, eliminating the need for manual emptying operations. The system performs self-maintenance by automatically removing accumulated dust from the cleaner's dust bin into the station's collection container.
Solution Approach 2:
The cleaner station serves as an intermediary device between the cleaner and the user, handling the dust emptying process. The station includes a dust discharge motor, suction flow path, and collection container that work together to automatically transfer and store dust without direct user involvement.
2Productivity
If the cleaner operates continuously without emptying the dust bin, then cleaning productivity is maintained, but residual dust deteriorates suction force and causes offensive odors
Solution Approach 1:
The system uses a sensor to detect when the dust bin is full or when dust discharge is needed, and automatically activates the dust discharge motor to empty the bin. This feedback mechanism ensures the cleaner maintains optimal suction performance by periodically removing residual dust without interrupting overall cleaning productivity.
Solution Approach 2:
The dust bin is emptied periodically through automatic discharge cycles controlled by the cleaner station, rather than requiring continuous manual intervention. The periodic dust discharge maintains suction force while allowing extended cleaning operation continuity between emptying cycles.
3Measurement precision
If the cleaner station uses a complex communication module to control dust discharge operations, then control precision is improved, but device complexity and cost increase
Solution Approach 1:
The system replaces complex electronic communication modules with simpler electrical connection-based control. The cleaner station uses basic electrical signals transmitted through the power connection between the cleaner and station to trigger dust discharge operations, eliminating the need for sophisticated wireless or wired communication hardware.
Solution Approach 2:
The electrical connection that provides power to the cleaner also serves as the communication channel for controlling dust discharge operations. This multi-functional use of the power connection simplifies the overall system by combining power transmission and control signaling into a single interface.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively removes residual dust and strands of hair, minimizing energy consumption and user exposure to noise, while allowing the cleaner to determine the type of charging holder for appropriate operation, providing convenient and hygienic maintenance.
Implementation Method 1
a suction motor configured to generate a suction force so that air containing dust is introduced into the dust bin
Implementation Method 2
a dust collecting motor disposed below the suction flow path in the internal space and configured to provide a suction force to the dust bin through the suction flow path

AI summary
The present disclosure relates to a cleaner station and a cleaner system, and a method for controlling the cleaner system. According to an embodiment, by driving the suction motor of the cleaner after the drive of the dust collecting motor of the cleaner station is finished, it is possible to suck back, into the dust bin, foreign substances such as strands of hair etc. which stuck and remain in an open end of the dust bin even after collecting the dust in the dust bin so that the foreign substances can be removed.
