Siphon Elbow Internal Locking for Narrow-Passage Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing siphon elbows require external tools for locking into angled configurations, complicating installation and increasing the diameter of the assembly, which can be a challenge in narrow passageways like those found in papermaking machines.
Innovation Solution
A siphon elbow with an internal locking system that uses a locking retainer and spring mechanism to automatically lock into an angled configuration without external tools, allowing the assembly to pivot smoothly through narrow passageways and maintain a smaller diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external locking system is used to secure the siphon elbow in an angled configuration, then the locking reliability is improved, but the device complexity and installation difficulty increase due to requiring external tools
Solution Approach 1:
The locking function is merged with the siphon elbow body itself. The locking retainer is integrated into the elbow structure, and the spring mechanism is contained within the elbow housing, eliminating the need for separate external locking devices and tools.
Solution Approach 2:
The siphon elbow performs its own locking function through the internal spring-loaded retainer mechanism. When the elbow is positioned at the desired angle, the spring automatically urges the retainer into the locking position, securing the elbow without requiring external tools or manual intervention.
2Reliability
If a traditional locking mechanism is used, then the locking function is achieved, but the assembly diameter increases making it difficult to pass through narrow passageways
Solution Approach 1:
The locking retainer and spring mechanism are nested within the hollow bore of the siphon elbow. The retainer fits inside the elbow body, and the spring is contained within the retainer structure, allowing the entire locking system to be housed within the existing elbow diameter without significant increase.
Solution Approach 2:
The locking retainer is designed to be movable along the bore axis, allowing it to retract inward when not engaged and extend outward when locking. This dynamic movement enables the locking mechanism to engage securely without permanently increasing the assembly's outer diameter.
3Reliability
If external tools are required for locking, then the locking reliability is improved, but the ease of operation deteriorates due to complicated installation procedures
Solution Approach 1:
The siphon elbow automatically performs the locking function through its internal spring-loaded retainer mechanism. During installation, as the elbow is positioned at the desired angle, the spring automatically urges the retainer into the locking position, securing the elbow without requiring external tools or manual intervention.
Solution Approach 2:
The spring is pre-loaded during manufacturing to provide the necessary locking force. This preliminary action ensures that when the elbow is installed and positioned, the locking mechanism is already prepared to engage automatically, eliminating the need for post-installation tooling or adjustment.
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
Facilitates easy installation and secure locking of the siphon elbow in angled configurations without external tools, reducing the assembly's diameter and enhancing operational efficiency in narrow spaces.
Implementation Method 1
The internal locking system is disposed in at least one of the bore of the first elongated body or the second elongated body and comprises a locking retainer having a bore extending therethrough and a first end configured to matingly engage the first end of the second elongate body. The first end of the locking retainer has a second chamfer extending along a circumference thereof. The internal locking system locks the second elongated body into an operating configuration

AI summary
A siphon elbow for pivotally connecting a first pipe and a second pipe in fluid communication. A first elongated body has a bore extending therethrough and a partially spherical indentation within the bore. A second elongated body has a bore extending therethrough and a generally spherical extension on a first end that pivotally engages the partially spherical indentation of the first elongated body. An internal locking system is disposed in at least one of the bores and locks the second elongated body into an operating configuration in which an angle formed between the first elongated body and the second elongated body is less than 180-degress. Pivoting of the second elongated body from an installation configuration in which the angle is approximately 180-degrees to the operating configuration activates the internal locking system.
