Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting devices face challenges in maintaining a sealed state during operation and external shocks, leading to potential dust leakage, while also being difficult to open and close effectively.
Innovation Solution
A dust collecting device with a sealing member comprising a first, second, and third sealing portion, and a connecting portion, which increases the contact area for enhanced sealing and allows for easy opening and closing, utilizing a restoring force to maintain the sealed state despite external shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sealing member is provided to easily open and close the dust collecting device, then the ease of operation is improved, but the reliability of sealing deteriorates due to dust leakage from external shocks
Solution Approach 1:
The sealing member is divided into multiple sealing portions (first, second, and third sealing portions) that contact different surfaces. This segmentation allows each portion to independently contribute to sealing, maintaining reliability while permitting easy operation through cumulative sealing effect rather than requiring excessive friction from a single complex seal.
Solution Approach 2:
Different sealing portions are positioned at different locations to contact specific surfaces (discharge cover inner surface, dust collecting case outer surface, and coupling surfaces). This local quality approach ensures that sealing is optimized at each critical interface, providing reliable sealing without requiring uniform high-friction contact across the entire sealing member, thus enabling easy opening and closing.
2Reliability
If a sealing member with excellent sealing effect is used, then the reliability of preventing dust leakage is improved, but the ease of operation deteriorates due to difficulty in opening and closing
Solution Approach 1:
The sealing member is divided into multiple sealing portions (first, second, and third sealing portions) that contact different surfaces. This segmentation allows each portion to independently contribute to sealing, maintaining reliability while permitting easy operation through cumulative sealing effect rather than requiring excessive friction from a single complex seal.
Solution Approach 2:
Different sealing portions are positioned at different locations to contact specific surfaces (discharge cover inner surface, dust collecting case outer surface, and coupling surfaces). This local quality approach ensures that sealing is optimized at each critical interface, providing reliable sealing without requiring uniform high-friction contact across the entire sealing member, thus enabling easy opening and closing.
3Reliability
If the contact area of the sealing member is increased to prevent dust leakage, then the reliability of sealing is improved, but the device complexity increases
Solution Approach 1:
Multiple sealing portions are merged into a single integrated sealing member rather than using separate sealing components. This combining approach increases the total contact area for reliable sealing while avoiding the complexity of assembling multiple separate sealing parts, thus reducing device complexity despite the increased sealing surface area.
Solution Approach 2:
The sealing member serves multiple functions simultaneously: the first sealing portion seals the discharge cover, the second sealing portion seals the dust collecting case, and the third sealing portion seals the coupling surface. This multi-functionality allows a single component to provide comprehensive sealing across multiple interfaces, increasing reliability without proportionally increasing device complexity.
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 enhanced sealing member effectively prevents dust leakage and maintains internal pressure, while allowing for easy operation and maintenance by increasing the contact area and utilizing a restoring force to ensure the sealed state is maintained.
Implementation Method 1
a sealing member between the dust collecting case and the discharge cover, the sealing member comprising a first sealing portion, a second sealing portion extending from the first sealing portion, a third sealing portion, and a connecting portion between the first sealing portion and the third sealing portion
Implementation Method 2
a cyclone dust collecting device is a device which separates the dust in the sucked air using a centrifugal force. The cyclone generates a rotating air current therein, separates the dust from the air

AI summary
Provided is a cleaner including a dust collecting device for separating dust from air, wherein the dust collecting device includes a dust collecting case having a dust discharging port opened to discharge the collected dust; a discharge cover coupled to one side of the dust collecting case to open and close the dust discharge port; and a sealing member provided to extend from an inner surface of the dust collecting case to a coupling surface of the dust collecting case while being in contact with the dust collecting case and thus to be sealed when the dust discharging port is closed.
