Solution Overview
Problem
Vacuum cleaner stations face issues with damage from scattered dust and dust leakage due to unintentional unlocking of the dust bag holder, especially when the dust bag is not properly positioned or is full.
Innovation Solution
A station design with a dockable dust canister, a housing for the dust bag, a cover that opens and closes, and a lever system that ensures the dust bag is securely mounted and prevents unintentional unlocking, using support members and a torsion spring for stability and recognition of proper mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holder is made detachable to allow dust bag removal, then ease of operation is improved, but reliability deteriorates due to unintentional unlocking and dust leakage
Solution Approach 1:
The dust bag is pre-mounted on the holder in a specific orientation, and the holder is pre-configured with engagement protrusions that automatically align with corresponding grooves in the housing during installation. This preliminary positioning ensures that the dust bag cannot be accidentally dislodged while remaining easily removable when intentionally detached.
Solution Approach 2:
A lever mechanism acts as an intermediary between the user's manual operation and the holder's locking state. The lever engages with the holder to secure it in place during normal operation, and when deliberately actuated, it releases the holder for removal. This intermediary mechanism prevents unintentional unlocking while maintaining ease of intentional removal.
2Ease of operation
If the cover is designed to open and close for dust bag access, then ease of operation is improved, but device complexity increases due to additional components
Solution Approach 1:
The cover mechanism is merged with the holder assembly, where the cover serves dual purposes: protecting the dust bag during operation and facilitating its removal. The cover's opening and closing motion is integrated with the holder's engagement and disengagement, eliminating the need for separate complex mechanisms for both functions.
Solution Approach 2:
The cover is designed to perform multiple functions: it protects the dust bag from dust and debris during operation, provides access to the dust bag for replacement, and assists in the loading and unloading of the dust bag. This multi-functionality reduces the need for additional components and simplifies the overall device structure.
3Reliability
If support members are added to secure the holder, then reliability is improved, but device complexity increases
Solution Approach 1:
The support function is extracted from a complex mechanical support structure and implemented through simple geometric features of the housing itself. The housing includes integrated support surfaces and engagement grooves that naturally guide and secure the holder in the correct position, eliminating the need for additional support members while maintaining high positioning accuracy and reliability.
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
Prevents damage from scattered dust and leakage by ensuring the dust bag is securely mounted and communicating with the accommodation chamber, enhancing the station's durability and reducing manufacturing costs through improved mechanical configuration.
Implementation Method 1
The lever is rotatably coupled in the housing and includes a torsion spring that provides an elastic force in the first direction.
Implementation Method 2
an inclined member having one region disposed in a section in which the dust bag slides and interferes with the dust bag based on the dust bag being mounted on the holder to be rotated in the second direction

AI summary
A station for a cleaning device is provided. The station includes an accommodation chamber configured to be docked with the dust canister, a housing configured to have a dust bag disposed therein, a cover configured to open and close one region of the housing, a holder configured to be detachable to the dust bag and selectively communicate the dust bag with the accommodation chamber, and a lever configured to have one end disposed in one region of the housing and rotate in a first direction to selectively interfere with the cover. The lever rotates in a second direction opposite to the first direction to close the cover based on the dust bag being mounted on the holder and in communication with the accommodation chamber.
