Detachable Vacuum Blower Locking Assembly for One-Handed Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners with detachable blowers are inconvenient to use, especially when one hand is injured or occupied, and existing locking assemblies fail to reliably secure the blower, risking accidental detachment.
Innovation Solution
A vacuum cleaner design featuring a detachable blower with a single handle and a locking assembly that includes a latch, resilient member, and locking shoulder, allowing for easy one-handed operation and secure attachment/detachment between the blower and tank cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two hand grip portions are formed on opposite sides of the detachable blower, then the blower can be securely held, but the user must use both hands to lift the vacuum cleaner, reducing convenience when one hand is injured or occupied
Solution Approach 1:
The patent applies asymmetry by providing a single hand grip portion positioned asymmetrically on the detachable blower rather than symmetric two-hand grips. This allows the user to lift the entire vacuum cleaner assembly with one hand, improving ease of operation while maintaining secure holding through the strategically positioned grip
2Adaptability or versatility
If a locking assembly is arranged between the dirt tank and the blower, then the blower can be detached for blowing operation, but existing locking assemblies cannot reliably lock the blower, risking accidental detachment
Solution Approach 1:
The patent applies dynamics by using a resilient member (spring) in the locking assembly that provides automatic engagement and dynamic locking. The resilient member ensures reliable locking through elastic force while allowing easy detachment when needed, combining reliability with adaptability
Solution Approach 2:
The locking assembly is designed to automatically lock the blower to the dirt tank without requiring additional fastening actions. The resilient member and latch mechanism self-engage when the blower is attached, providing reliable locking automatically while maintaining the ability to detach when needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient one-handed lifting and secure locking of the blower, enhancing usability and reliability by reducing the risk of accidental detachment during use.
Implementation Method 1
