Rotating Oxygen Hose Bracket for Compact Flexible Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen hose fixation devices for ventilators are bulky, occupy excessive space, and increase manufacturing costs due to large components, limiting installation flexibility and user convenience.
Innovation Solution
A device comprising a base detachably attached to a plane, a rotatably engaged bracket with a 0-360 degree rotation, and at least one clamp, allowing the oxygen hose to be fixed and adjusted through clamps on the bracket and a hose hook with anti-slip features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vertical support rod, rotating assembly and horizontal support rod are used to support the breathing hose, then the breathing hose can be supported and positioned freely, but the device occupies more space and becomes longer
Solution Approach 1:
The patent applies nesting by placing the horizontal support rod inside the vertical support rod, and the breathing hose inside the horizontal support rod. This nested structure allows multiple functional components to occupy the same spatial envelope, significantly reducing the overall device volume while maintaining the ability to extend and position the breathing hose freely when needed.
2Reliability
If the specifications of each component are increased to meet user needs, then the device can support the breathing hose effectively, but the manufacturing cost increases
Solution Approach 1:
The patent divides the support system into segmented, modular components: a vertical support rod, a rotating assembly, and a horizontal support rod that can be extended. This segmentation allows each component to be manufactured at smaller, more economical specifications while maintaining overall support capability through the coordinated arrangement of parts. The modular design also enables standardized production of individual components.
3Stability of the object's composition
If the device components are made larger to ensure stability and support, then the breathing hose can be securely fixed, but the installation location cannot be freely selected
Solution Approach 1:
The nested structure enables the device to maintain a compact form factor that can be installed in various locations, while the ability to extend the horizontal support rod outward from the vertical rod provides sufficient reach and stability for securing the breathing hose. The nesting principle allows the device to adapt to different installation spaces without requiring large component specifications.
4Ease of operation
If a complex combination of support rods and rotating assemblies is used, then the breathing hose can be freely positioned, but the device complexity increases
Solution Approach 1:
The patent segments the positioning function into distinct rotational joints: a vertical rotation joint allowing the horizontal rod to rotate around the vertical rod, and potentially additional rotation joints in the horizontal rod itself. This segmentation of motion functions into simple rotational movements makes the overall system easier to control and operate compared to a single complex mechanism, while achieving the same positioning flexibility.
