Vacuum Cleaner Link Assembly for Stable Cover Member Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners often have difficulty maintaining the cover member in an open state, which can compromise safety and user convenience, as existing designs lack a simple and stable mechanism for opening and closing the cover member.
Innovation Solution
A vacuum cleaner design featuring a rotatable cover member with a link assembly and a spring mechanism that allows for easy opening and closing, using a rotating link and slider system with a supporting protrusion and guide ribs to maintain the cover member in an open position, enhancing user convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cover member is rotatably installed to be opened and closed, then user convenience is improved, but the cover member cannot be stably maintained in an opened state
Solution Approach 1:
The link assembly converts the rotational movement of the cover member into linear reciprocating movement of the slider, creating a dynamic mechanism that allows the cover to be easily opened and closed while maintaining stable positions through the link assembly's geometric constraints
Solution Approach 2:
The link assembly acts as an intermediary mechanism between the rotatable cover member and the cleaner body, using a slider and rotating link to transmit and control movement, enabling both ease of operation and stable positioning
2Ease of operation
If a simple opening and closing mechanism is used, then ease of operation is improved, but the mechanism lacks stability to maintain the open state
Solution Approach 1:
The link assembly is segmented into distinct functional components: a slider for linear movement, a rotating link for angular movement, and a supporting protrusion for position maintenance. This segmentation allows each component to perform its specific function while keeping the overall mechanism relatively simple
3Ease of operation
If the cover member is opened and closed frequently, then user convenience is improved, but safety may be compromised without a stable open state
Solution Approach 1:
The link assembly with spring automatically maintains the cover member in appropriate positions (open or closed) based on user input, eliminating the need for manual positioning efforts and ensuring safety through automatic stable positioning
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 allows for a stable and easy operation of the cover member, improving user safety and convenience by enabling simple and secure opening and closing, while maintaining the suction hose connection, thus enhancing cleaning efficiency.
Implementation Method 1
a spring provided between the cover member and the slider to elastically support the slider

AI summary
Provided is a vacuum cleaner including a cleaner body having a motor generating a suction force; a dust container provided at a front end of the cleaner body and configured to collect dust sucked through a suction port; a cover member rotatably installed at an upper end of the cleaner body and opened and closed to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction portion suctioning the dust and the other side is connected to the cover member; a link assembly configured to connect between the cover member and the cleaner body; and a link assembly accommodating portion formed at one side of the cleaner body so that at least a part of the link assembly is inserted and configured to restrict the link assembly when the cover member is opened and thus to allow the cover member to be maintained in an opened state.
