Vacuum Cleaner Hose Holder for Secure Fixation Without Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in securely and flexibly attaching suction hoses, leading to potential detachment during transport and increased workload, as the alignment and design of the hose end piece must match the holding receptacle for secure fixation.
Innovation Solution
The vacuum cleaner features multiple holding elements with different fastening options and conical end pieces, allowing for secure attachment without precise alignment, accommodating various suction hose designs and reducing the risk of detachment during transport or use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single receptacle design is used for holding the suction hose end piece, then the structure is simple, but the suction hose may not be held securely enough when alignment is not precise
Solution Approach 1:
The holding element is divided into multiple receptacles (first receptacle and second receptacle) with different geometries. Each receptacle is designed to accommodate different types of hose end pieces or different winding positions, ensuring secure fixation regardless of alignment precision or hose type.
2Ease of operation
If the suction hose is wound up loosely by users, then the operation is easy, but the end piece may not be in the correct position for insertion into the receptacle
Solution Approach 1:
The receptacles are designed with different geometries and orientations to accommodate variations in hose end piece position caused by loose winding. The first receptacle and second receptacle provide alternative insertion points, allowing users to secure the hose even when alignment is not precise.
3Reliability
If multiple holding means are provided on the holding element, then different sections of the suction hose can be fixed securely, but the device complexity increases
Solution Approach 1:
Multiple receptacles are integrated into a single holding element that is mounted on the vacuum cleaner housing. This combines multiple fixation functions into one unified component, providing secure fixation for different hose sections while minimizing overall device complexity through integrated design.
