Exhaust Line Assembly Pivotable Mounting Lug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing exhaust line assemblies for bottle attachment apparatuses suffer from deformation due to flexural stress, leading to friction issues and reduced rotatability of the closure cap, which can result in contamination and hindered operation, especially when the closure cap is not properly aligned with the tip, causing liquids to spill and creating an unsafe working environment.
Innovation Solution
The implementation of a pivotable mounting lug using a rotary joint with a physically present axis of rotation, allowing for arbitrary rotational movement without deformation, ensures the closure cap can be moved into position with minimal resistance, maintaining its alignment outside the liquid flow region and preventing plastic deformation, thus ensuring secure and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mounting lug is made flexible to allow closure cap movement, then the closure cap can be positioned, but flexural stress causes deformation and reduced rotatability
Solution Approach 1:
The mounting lug is transformed from a static flexible element to a dynamic articulated mechanism. By introducing a rotary joint with a physically present axis of rotation, the mounting lug can pivot between different positions (hanging down vs. horizontal) without experiencing flexural stress. This dynamic solution maintains rotatability while enabling closure cap positioning.
2Stability of the object's composition
If the mounting lug is rigid to maintain shape, then deformation is prevented, but the closure cap cannot be moved into position
Solution Approach 1:
The mounting lug is designed as an articulated mechanism with a rotary joint, allowing it to change its spatial configuration dynamically. The lug itself remains rigid and maintains its shape, but the entire assembly can pivot about the rotary joint axis. This enables the closure cap to be moved into position without deforming the mounting lug's structure.
3Object-affected harmful factors
If the closure cap hangs down vertically, then it stays outside liquid flow region, but it cannot be aligned with the tip for closing
Solution Approach 1:
The mounting lug with rotary joint enables the closure cap to assume different positions dynamically. In the rest position, the closure cap hangs down vertically outside the liquid flow region. When operation is needed, the mounting lug can be pivoted to align the closure cap with the tip horizontally, allowing proper sealing while maintaining contamination protection during normal operation.
Solution Approach 2:
The rotary joint acts as an intermediary mechanism between the mounting lug and the closure cap positioning requirement. It mediates between the need to keep the closure cap outside the liquid flow region and the need to align it with the tip for closing, allowing smooth transition between these two states without friction or resistance.
4Reliability
If friction is reduced for smooth rotation, then rotatability is maintained, but the mounting lug deforms under flexural stress
Solution Approach 1:
The flexible mounting lug mechanism is replaced with an articulated mechanical system featuring a rotary joint with a physically present axis of rotation. This substitution eliminates flexural stress and deformation while maintaining smooth rotatability. The rotary joint provides a defined pivot point that allows frictionless rotation without compromising the structural integrity of the mounting lug.

AI summary
An exhaust line assembly for a bottle attachment apparatus for handling liquids has an outrigger-type mount, an exhaust line which is disposed and guided in the mount and which terminates in a tip, and a mounting lug which has a closure cap attached to the end thereof and which is fastened to the exhaust line assembly, the tip of the exhaust line being closable by way of the closure cap. The mounting lug at that end thereof which is fastened to the exhaust line assembly is articulated so as to be pivotable by a rotary joint which has a physically present axis of rotation.
