Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hose fixing mechanism using bent steel wire is used, then the hose can be fixed on the suction cleaner, but the structure becomes complex and the cost increases
Solution Approach 1:
The patent combines multiple functions into a single elastic support component. The elastic support integrates the hose clamping function, the mounting function, and the adjustable function into one piece, eliminating the need for separate bent steel wire and multiple assembly parts. This merging reduces structural complexity while maintaining hose fixing capability.
Solution Approach 2:
The elastic support is designed as a multi-functional component that can accommodate hoses of different diameters through adjustable arm-shaped components. It serves as both a clamping mechanism and a mounting mechanism, and can be installed on different locations of the suction cleaner, making it a universal solution that replaces multiple specialized parts.
2Reliability
If a hose fixing mechanism using bent steel wire is used, then the hose can be fixed on the suction cleaner, but the assembly and disassembly becomes difficult
Solution Approach 1:
The elastic support incorporates elastic deformation capability, allowing it to dynamically adjust during assembly and disassembly. The arm-shaped components can flex and the buckling components can engage/disengage from buckling holes, enabling easy tool-free assembly and disassembly while maintaining reliable hose fixation during use.
Solution Approach 2:
The elastic support is designed to be self-assembling through its elastic properties. When the arm-shaped components are inserted, the elasticity automatically provides the clamping force and the buckling components automatically engage with the buckling holes, eliminating the need for additional fastening operations or tools. The mechanism serves itself by using its own elastic energy for assembly.
3Reliability
If a fixed hose support structure is used, then the hose can be supported, but the packaging volume of the suction cleaner increases
Solution Approach 1:
The hose support mechanism is segmented into detachable components: the elastic support can be separated from the suction cleaner body by simply releasing the buckling components from the buckling holes. This segmentation allows the support mechanism to be removed or folded during packaging, reducing the overall packaging volume while maintaining full hose support capability during use.
4Reliability
If a hose support mechanism is designed for specific hose diameter, then the hose can be supported, but the adaptability to different hose diameters is reduced
Solution Approach 1:
The arm-shaped components can be adjusted to change the parameters of the support structure. The distance between the arms, the angle of the buckling components, and the clamping force can all be modified by repositioning the components along the elastic support body, allowing the same mechanism to adapt to hoses of different diameters while maintaining reliable support capability.

AI summary
A hose support mechanism for a vacuum cleaner including a machine body includes at least one elastic support for supporting a hose, wherein the elastic support can elastically deform to mutually buckle with or separate from the machine body. The hose support mechanism can be assembled and disassembled conveniently without using other tools, and can be adapted for hoses with different hose diameters. When the vacuum cleaner is provided with hoses with different hose diameters, there is no need to redesign the hose support mechanism, thereby enhancing the generality of the vacuum cleaner.
