Foldable Wand Vacuum Cleaner for Compact Storage and Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rigidity of vacuum cleaner wands makes them difficult to use and store, especially when a vacuum unit is attached, due to their inflexible design.
Innovation Solution
A vacuum cleaning device with a foldable wand that includes a flexible air passage and pivotably connected segments, allowing it to be folded 180° for storage and providing a storage configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid wand is used in the vacuum cleaner, then structural strength and stability are improved, but ease of operation and storage are worsened
Solution Approach 1:
The wand is divided into multiple rigid segments that can be pivotally connected, allowing the wand to be segmented into foldable sections while maintaining structural integrity in each segment
Solution Approach 2:
The wand transitions from a static rigid structure to a dynamic foldable structure with pivotal connections, enabling it to change configuration between extended (for cleaning) and folded (for storage) states
2Stability of the object's composition
If a rigid wand with vacuum unit attached is used, then structural stability is improved, but ease of maneuverability is worsened
Solution Approach 1:
The vacuum cleaner is segmented into modular components (vacuum unit, wand segments, cleaning head) connected by pivotal joints, allowing independent movement and maneuvering while maintaining overall structural stability during operation
Solution Approach 2:
The vacuum cleaner system becomes dynamically reconfigurable, allowing the wand and vacuum unit to be positioned at various angles and configurations to facilitate maneuverability in different cleaning scenarios

AI summary
Vacuum cleaning devices include foldable wands to provide a storage configuration and/or facilitate use. A vacuum cleaning device includes a wand having a first end coupled to a vacuum unit and a second end coupled to a vacuum head or surface cleaning head. The wand defines an air passage allowing air to pass from the surface cleaning head to the vacuum unit and includes a flexible air passage along at least a portion of the wand. The wand also includes a plurality of segments pivotably connected together such that the wand is foldable about 180° in a forward direction until the vacuum unit is positioned proximate a top of the surface cleaning head, thereby providing a storage configuration.
