Vacuum Wand Storage Assembly for Secure Bottom-Mount Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable holders for vacuum accessories on wet/dry vacuums often slip fit and lack secure attachment, leading to potential dislodgment and loss during use or movement, especially for vacuum hose extension wands which are cumbersome to secure upright.
Innovation Solution
A bottom-mount vacuum hose wand storage assembly with arched channels and securement assemblies on the vacuum debris collection drum, featuring a front and rear securement assembly with wand positioning and retaining stops, and springing means to elevate and guide wands into position, ensuring secure storage and preventing accidental loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable holders are used for vacuum accessories, then ease of operation is improved, but reliability deteriorates due to potential dislodgment and loss during use or movement
Solution Approach 1:
The accessory holder is divided into separate components: a mounting plate that attaches to the vacuum body, and a detachable holder portion that can be removed independently. This segmentation allows the holder to be easily detached for cleaning or replacement while maintaining secure attachment when in use through the mounting plate's engagement features.
Solution Approach 2:
The accessory holder is designed to nest within or against the vacuum body structure, with the mounting plate engaging into recesses or against surfaces of the vacuum housing. This nesting arrangement ensures compact storage and secure positioning while allowing easy removal when needed.
2Ease of operation
If extension wands are stored upright, then ease of operation is improved for quick access, but device complexity increases due to need for securement structures
Solution Approach 1:
The extension wand storage function is merged with the accessory holder structure. The mounting plate serves dual purposes: securing small accessories and providing a structured environment for storing extension wands vertically. This combination eliminates the need for separate wand storage structures while maintaining quick access capability.
Solution Approach 2:
Instead of storing extension wands horizontally or in complex racks, the design utilizes vertical dimension by allowing wands to rest upright against the mounting plate or holder structure. This vertical storage approach simplifies the overall structure while enabling quick visual identification and access.
3Reliability
If accessory holders are permanently secured to vacuum, then reliability is improved, but ease of operation deteriorates due to inability to remove for cleaning or storage
Solution Approach 1:
The accessory holder transitions from a static permanent attachment to a dynamic system with two states: securely attached (when accessories need to be held) and easily removable (when cleaning or storage is needed). The mounting plate incorporates engagement features that provide firm attachment during use but allow simple detachment when required.
Solution Approach 2:
The mounting plate is pre-designed with engagement features that automatically secure the holder to the vacuum body upon attachment, eliminating the need for complex fastening procedures. This preliminary preparation of engagement features ensures reliable attachment while maintaining ease of removal through simple disengagement of these pre-configured features.

AI summary
A vacuum extension wand accessory storage assembly for use with a wet/dry vacuum that improves user access to the wands while simultaneously preventing accidental loss or dislodgement of the wands when the vacuum is not in use. The wand storage design includes the combination of a channeled, shaped surface formed in the bottom of the vacuum collection drum and an accessory attachment system on the bottom of the vacuum appliance having both front and rear securement assemblies which in combination secure the extension wands in place below the collection drum of the vacuum appliance in the event of vacuum transportation, lifting, or storage.
