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

VSEngineering 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

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #13The other way round (Inversion)

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

Engineering Contradiction:
Improvehandle accessibilityVSAvoiddust container stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

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.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

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

Engineering Contradiction:
Improvecarrying comfortVSAvoiddust container envelope
Core Design Contradiction:
Ease of operationVSVolume of moving object

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.

Inventive Principle:
Principle #7Nested doll (Nesting)
