Vacuum Hose Latch Assembly With Preassembled Clamp Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latching devices for connecting handles to vacuum cleaner suction tubes are expensive due to direct installation on the suction tube, making assembly costly and complex.
Innovation Solution
A latching device with a clamping element positively connected to the sleeve, where the lever button is pivotally held between the clamping element and the sleeve, allowing preassembly and easy attachment to the suction tube, featuring a return spring for reliable locking and unlocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the latching device is installed directly on the vacuum cleaner suction tube, then the connection between handle and suction tube is secure, but the assembly cost and complexity increase significantly
Solution Approach 1:
The latching device is divided into separate modular components: a sleeve that can be mounted on the suction tube, a lever button with latching projection, a clamping element, and a return spring. These components can be preassembled together and then attached to the suction tube as a unit, reducing on-site assembly complexity while maintaining connection security
Solution Approach 2:
The sleeve, lever button, clamping element, and return spring can be preassembled into a complete latching mechanism before being mounted on the suction tube. This preliminary assembly allows quality control and testing to be performed beforehand, simplifying the final installation process while ensuring reliable connection
2Device complexity
If the latching device components are held together without a clamping element, then the structure is simpler, but the components may become detached or lost during assembly or detachment
Solution Approach 1:
The clamping element integrates multiple functions: it secures the lever button to the sleeve, provides a mounting surface for the return spring, and ensures all components remain together during assembly and detachment. By combining these retention functions into a single clamping element, the overall structure remains relatively simple while reliably preventing component loss
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 assembly process by preassembling components, ensures stability and reliability of attachment, and allows easy reassembly, reducing costs and complexity while maintaining secure connection and detachment functionality.
Implementation Method 1
the return spring causes the lever button and thus the latching projection to be reset into a locking position
