Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaner stations with bagless type dust collecting parts face issues of dust scattering, winged insects escaping, and odor spread when the dust collecting part is separated, and there is a need for effective sealing and sterilization to prevent these problems.
Innovation Solution
A cleaner station design featuring a dust collecting part with an inlet tube and inlet tube cover that forms a specific curvature, a rib to deform and support the cover, and a sterilizing light emitting member to irradiate the dust collecting body, ensuring tight sealing and sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a bagless type dust collecting part is used to eliminate environmental pollution and cost problems, then environmental friendliness and operational cost are improved, but dust scattering, insect escape, and odor spread occur when the dust collecting part is separated
Solution Approach 1:
The patent employs a flexible sealing film that deforms under suction pressure to create a dynamic seal between the suction pipe and bag inlet. This flexible film maintains airtightness during operation while allowing the bag to be removed and reinstalled without compromising sealing performance, thus preventing dust scattering and odor spread in bagless design
Solution Approach 2:
The patent applies preliminary sealing measures by positioning the sealing film at the bag inlet before dust collection begins. The film is pre-configured to deform and seal the connection point, preventing dust and odors from escaping during the entire operation period until the bag is intentionally removed
2Productivity
If the dust collecting part is made larger to reduce dust emptying frequency, then productivity is improved, but the device becomes more complex and harder to separate
Solution Approach 1:
The patent divides the dust collection system into separable modules: a removable bag or dust collecting part that can be detached from the main body. This segmentation allows the dust collecting part to be large enough for reduced emptying frequency while maintaining ease of removal and installation, preventing the entire system from becoming overly complex
3Reliability
If the inlet tube cover is made to tightly seal the inlet tube to prevent dust scattering and insect escape, then sealing performance is improved, but the cover may sag due to its own weight
Solution Approach 1:
The patent designs the inlet tube cover with a curved or arched structure rather than a flat design. This curvature provides structural strength to prevent sagging under the cover's own weight while maintaining effective sealing contact with the inlet tube, thus preventing dust scattering and insect escape without compromising structural stability
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
The design effectively prevents dust scattering, insect escape, and odor spread while ensuring the inlet tube remains sealed, and the sterilizing light effectively kills microorganisms and winged insects.
Implementation Method 1
a sterilizing light emitting member for irradiating a sterilizing light into the dust collecting body

AI summary
Disclosed is a cleaner station including: a suction flow path having an inlet end communicating with a dust bin of a cleaner; and a dust collecting part connected to an outlet end of the suction flow path and collecting dust inside the dust bin of the cleaner. The dust collecting part includes: a dust collecting body having a dust inlet connected to the outlet end of the suction flow path; an inlet tube extending inward from a circumferential surface of the dust inlet and having an end forming a curvature circle with a specific curvature when viewed from one side; and an inlet tube cover disposed at the end of the inlet tube and opening and closing the inlet tube. Accordingly, by closing the inlet tube when the dust collecting part is separated from the cleaner station, the cleaner station may prevent dust from scattering, winged insects from escaping or odors from spreading.
