Vacuum Cleaner Suction Pipe Catch Device with Clamp-Held Lever Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catch devices for vacuum cleaner suction pipes are complex to mount directly on the pipe, making the process cumbersome and prone to part separation during detachment.
Innovation Solution
A catch device with a clamp element that holds the lever button and reset spring captive on a sleeve, allowing for pre-mounting of all parts and simplified attachment to the suction pipe, featuring a pivotally held lever button between the clamp element and sleeve, with guide bushes and a stabilization bridge for enhanced stability and guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the catch device is mounted directly on the vacuum cleaner suction pipe, then the handle can be connected to the suction pipe, but the mounting process becomes very complex
Solution Approach 1:
The catch device is segmented into a separate assembly comprising the sleeve, lever button, catch projection, and reset spring, which can be pre-assembled and tested independently before being mounted as a complete unit onto the vacuum cleaner suction pipe. This segmentation reduces mounting complexity while maintaining connection reliability.
Solution Approach 2:
The lever button and reset spring are preliminarily positioned and secured within the sleeve before the entire catch device assembly is mounted on the suction pipe. The reset spring is pre-compressed or pre-positioned to ensure proper function, eliminating the need for complex on-site adjustments during final installation.
2Reliability
If the catch device is mounted directly on the vacuum cleaner suction pipe, then the handle connection is secure, but the mounting effort increases significantly
Solution Approach 1:
The catch device components (sleeve, lever button, catch projection, reset spring) are pre-assembled into a ready-to-mount configuration. The reset spring is pre-positioned and the lever button is preliminarily secured, allowing the entire assembly to be installed as a single unit, significantly reducing mounting time while maintaining secure connection.
Solution Approach 2:
Multiple components (sleeve, lever button, catch projection, reset spring) are merged into a single integrated catch device assembly that functions as one unit. This consolidation allows all components to be mounted simultaneously in one operation rather than requiring separate installation steps for each component.
3Ease of manufacture
If the lever button is freely positioned in the sleeve, then assembly is simple, but the lever button may detach during use
Solution Approach 1:
The clamp element acts as an intermediary component between the lever button and the sleeve. It provides a simple yet effective retention mechanism that prevents the lever button from detaching during use, while maintaining assembly simplicity through a straightforward clamping action that requires minimal complex fastening operations.
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
Simplifies the mounting process, ensures reliable fastening and stability of the lever button, and prevents part separation during detachment, allowing for easy reassembly and adjustable length of the vacuum cleaner suction pipe.
Implementation Method 1
The reset spring then causes a reset of the lever button, and thus, of the catch projection into a locking position
Implementation Method 2
the lever button pivoting back around the pivot axis
