Vacuum Cleaner Handle with Spring-Hook Blocking for Stable Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner handle systems lack an efficient, simple, and automatic mechanism for blocking the handle in a position that allows safe and convenient carrying and storage.
Innovation Solution
A pivotally mounted handle with two positions, where a spring hook engages a protrusion on the vacuum cleaner body to block rotation in the second position, enabling easy folding and automatic return to a lower position, preventing accidental movement and enhancing user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to block the handle in vertical position, then handling stability is improved, but device complexity increases
Solution Approach 1:
The spring-loaded hook automatically engages with the protrusion when the handle reaches the vertical position, blocking it without user intervention. The system serves itself by using the handle's own movement to trigger the locking action, eliminating the need for manual locking operations and reducing overall system complexity despite adding automatic blocking functionality.
Solution Approach 2:
The patent replaces complex multi-component locking mechanisms with a simple spring-loaded hook and protrusion system. This mechanical substitution uses elastic potential energy storage and release instead of cam-based or multi-linkage locking systems, significantly reducing the number of parts while maintaining reliable handle positioning.
2Ease of operation
If an automatic blocking system is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring-loaded hook automatically engages with the protrusion when the handle reaches the vertical position, blocking it without user intervention. The system serves itself by using the handle's own movement to trigger the locking action, eliminating the need for manual locking operations and reducing overall system complexity despite adding automatic blocking functionality.
3Reliability
If a spring-loaded hook blocking system is used, then handling stability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces complex multi-component locking mechanisms with a simple spring-loaded hook and protrusion system. This mechanical substitution uses elastic potential energy storage and release instead of cam-based or multi-linkage locking systems, significantly reducing the number of parts while maintaining reliable handle positioning.
Solution Approach 2:
The spring-loaded hook is integrated directly into the handle structure, and the protrusion is formed as part of the vacuum cleaner body housing. This merging of components eliminates the need for separate locking mechanism assemblies, reducing manufacturing steps and assembly operations while maintaining the blocking functionality.

AI summary
A handle (20) for a vacuum cleaner which is pivotally mounted on a vacuum cleaner body (10) and which can be moved between a first position in which the handle (20) is located substantially horizontal with respect to the vacuum cleaner body (10) and a second position in which the handle (20) is substantially vertical with respect to the vacuum cleaner body (10), wherein the handle (20) in said second position has at least two positions, namely a lower position in which the handle (20) can be rotated freely and an upper position in which a hook (22) of a spring (23) engages a protrusion (13) of the vacuum cleaner body (10). The present invention provides a simple and efficient solution for blocking the handle of the vacuum cleaner in a position in which the vacuum cleaner can be carried by the user in a safe and comfortable manner. The invention also relates to an automatic release system for the handle of a vacuum cleaner.
