Vacuum Wand Locking Structure for Easier Reinsertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses lack a convenient and ergonomic design for removing and reinserting the above-floor cleaning wand, making the process cumbersome and difficult for users.
Innovation Solution
A surface cleaning apparatus with a wand release actuator and lock mechanism that allows the wand to be removably mounted to the upper portion, featuring a flexible air flow conduit and a wand lock that secures the wand in place, enabling easier alignment and reinsertion, and a portable surface cleaning unit that can be independently removed and reattached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wand is permanently fixed to the upper portion, then the structure is simpler and more stable, but the ease of operation for removing and reinserting the wand deteriorates
Solution Approach 1:
The wand mounting structure is segmented into separate components: a locking member on the wand, a receiving structure on the upper portion, and a release actuator. This segmentation allows the wand to be easily removed and reinserted while maintaining structural integrity when locked.
Solution Approach 2:
The wand mounting system transitions from a static fixed connection to a dynamic removable connection. The locking member can engage with the receiving structure to secure the wand, or be released by the actuator to allow removal, providing operational flexibility.
2Ease of operation
If the upper portion has a large vertical extent to accommodate the locking mechanism, then the locking function is more reliable, but the ease of operation for reinserting the wand deteriorates
Solution Approach 1:
The release actuator serves as an intermediary mechanism that translates user input into the movement of the locking member. This intermediary allows the locking mechanism to be operated from a convenient height without requiring the upper portion to have excessive vertical extent.
Solution Approach 2:
The locking mechanism is designed to operate in a horizontal plane rather than requiring significant vertical space. The locking member moves laterally to engage or disengage from the receiving structure, reducing the vertical extent of the upper portion.
3Ease of operation
If the wand release actuator is integrated with the locking mechanism, then the device complexity is reduced, but the ease of operation for releasing the wand may deteriorate
Solution Approach 1:
The release actuator is merged with the locking mechanism as an integrated assembly that moves together. When the actuator is pressed, it directly drives the locking member to disengage from the receiving structure, simplifying the overall design while maintaining ease of operation.
