Dust Container Handle Structure for Stable Vacuum Cleaner Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with dust containers lack a secure and reliable connection between the handle and the dust container, leading to potential dust leakage and instability during carrying and emptying.
Innovation Solution
A vacuum cleaner design featuring a handle with a first connecting element that grips the dust container's lower outer surface, minimizing shearing forces and ensuring a firm, long-lasting connection, along with additional support feet for stability, and a second connecting element with a screw fixing mechanism for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the handle is attached to the dust container using conventional connection methods, then the handle can be easily attached, but the connection is unreliable and prone to premature loosening due to shearing forces
Solution Approach 1:
The first connecting element transitions the force transmission from a lateral shearing connection to a vertical compressive connection by reaching under the dust container. This dimensional change allows the handle to support the dust container weight directly along the vertical axis, eliminating shearing forces that cause premature loosening in conventional lateral attachment methods.
Solution Approach 2:
Instead of attaching the handle to the upper or side surface of the dust container as in conventional designs, the first connecting element inverts the attachment approach by reaching under the dust container from below. This inverted configuration allows the handle to grip and support the dust container from underneath, fundamentally changing the force distribution and connection reliability.
2Ease of operation
If the handle is positioned on the outer surface of the dust container, then the handle is easily accessible, but the dust container is unstable and requires additional stabilization during handling
Solution Approach 1:
The first connecting element acts as a counterbalancing support structure by reaching under the dust container and transferring its weight to the handle. This creates a stable support system where the handle bears the full weight of the dust container, eliminating the need for additional stabilization hands or supports that would be required with surface-mounted handles.
3Ease of operation
If the handle protrudes beyond the outer contour of the dust container, then the handle provides better leverage for carrying, but the handle may interfere with storage or handling in confined spaces
Solution Approach 1:
The first connecting element is nested within the space under the dust container, utilizing the internal volume rather than adding external bulk. This allows the handle to extend outward for ergonomic gripping while the connection mechanism remains compact and integrated within the dust container's existing envelope, avoiding interference with storage in confined spaces.
