Cleaner Dust Collection Unit Coupling to Prevent Accidental Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners risk accidental detachment of the dust collection unit from the main body when lifted, potentially causing damage or injury due to the main body falling, and lack a mechanism to prevent coupling release without additional components.
Innovation Solution
Incorporating a rotating shaft and connection member system within the cleaner, where the connection rotating shaft can move between positions to either allow or prevent rotation of the connection unit, utilizing a connection fixing rib and dust collection unit fixing rib to maintain coupling when lifted, and employing elastic members to facilitate movement and return to the desired positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection unit is integrated with a button member to allow easy coupling and decoupling, then the ease of operation is improved, but the reliability of maintaining coupling during lifting is worsened
Solution Approach 1:
The connection rotating shaft is designed to move between a first position (allowing rotation for coupling/decoupling) and a second position (preventing rotation during lifting). This dynamic reconfiguration of the connection unit's rotational capability based on operational state resolves the contradiction between ease of operation and reliability of maintaining coupling.
2Ease of operation
If the dust collection unit can be easily detached by pressing the button member, then the ease of operation is improved, but the harmful factors increase due to potential accidental detachment and damage
Solution Approach 1:
The connection rotating shaft proactively moves to the second position before lifting occurs, preliminarily preventing the harmful effect of accidental detachment. By anticipating the lifting action and pre-configuring the connection unit to prevent rotation, the system eliminates the risk of harmful factors while preserving easy detachment when intentionally triggered.

AI summary
A cleaner includes a main body, a dust collection unit coupled with the main body at a part of the main body, and including a rotating shaft installing part, a connection member configured to connect the dust collection unit to the main body, and rotatably installed in the dust collection unit, an insertion part formed in the main body such that at least one part of the connection member is inserted into the insertion part, and a connection rotating shaft rotatably rested on the rotating shaft installing part such that the connection rotating shaft becomes a center of rotation of the connection member, the connection rotating shaft configured to move relatively along the rotating shaft installing part.
