Vacuum Cleaner Tool Joint With Ring-Segment Pivot Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner suction tool connections to suction wands, hoses, or handles are complex, costly, and prone to failure due to insufficient durability and robustness, particularly in plastic components, while requiring user-friendly assembly and disassembly for flexible functionality.
Innovation Solution
A pivotal and rotational connection arrangement using a pivot element and a rotation element with circumferential grooves and partial ring segment elements, allowing limited rotational motion and secure axial alignment, enabling simple assembly and disassembly, and utilizing plastic or low-friction materials for economic mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection structures are used to connect suction tool to vacuum cleaner, then the connection can be established, but the structure becomes complex and costly with insufficient durability
Solution Approach 1:
The connection structure is divided into distinct functional elements: a pivot element with circumferential groove, a rotation element with corresponding groove, and partial ring segment elements that fit into the grooves. This segmentation allows each component to be simple and easily manufactured while collectively providing a durable, robust connection that resists failure over time.
2Reliability
If robust connection structure is implemented to ensure long operating lifetime, then durability is improved, but assembly and disassembly becomes difficult
Solution Approach 1:
The connection structure incorporates dynamic characteristics through the partial ring segment elements that can be inserted and removed, and the pivot/rotation elements that allow controlled movement. The grooves guide the ring segments into position during assembly, making the connection robust yet easily assembled and disassembled by users.
3Ease of manufacture
If simple plastic components are used for mass production, then manufacturing cost is reduced, but the connection lacks sufficient robustness and force transmission
Solution Approach 1:
The connection structure employs composite design where plastic components (pivot element, rotation element) provide economical mass production and basic structural integrity, while the partial ring segment elements inserted into the grooves provide enhanced mechanical strength and force transmission capability. This composite approach maintains simplicity for manufacturing while achieving robustness.

AI summary
A connection arrangement between a vacuum cleaner and a suction tool includes a pivot element pivotably connected to the suction tool and a rotation element rotatably coupled to the pivot element. A suction wand, hose, handle or other vacuum port of the vacuum cleaner is removably connected to a connection end of the rotation element. Coupling ends of the pivot and rotation elements are inserted one in the other, and respectively have circumferential grooves that form a circumferential channel therebetween. Plural partial ring segment elements are received in the circumferential channel to form a connection ring that rotatably secures the pivot and rotation elements. The ring segment elements are inserted into or removed from the channel through a selectively coverable opening in the rotation element or the pivot element. A catch cooperates with a detent to hold a vertically pivoted, rotationally centered rest position of the components.
