Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for opening centrifugal separators are aggressive, complex, and can deform the lock ring or require modifications to the separator, posing ergonomic and structural risks.
Innovation Solution
A centrifugal separator opening tool with pivotable coupling elements and actuators that generate torque without large bending forces, allowing easy and ergonomic use without modifying the separator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a sledgehammer is used to strike the spanner for opening the lock ring, then opening torque can be generated, but the lock ring may be deformed and thread jamming may occur
Solution Approach 1:
The patent introduces a specialized opening tool as an intermediary device between the operator and the lock ring. This tool includes a bracket that engages with the lock ring and a mechanism that distributes opening torque evenly around the lock ring's circumference, preventing localized deformation while still generating sufficient force to loosen the threaded connection.
2Force
If a heavy sledgehammer is used to generate opening torque, then sufficient force can be applied, but ergonomic performance deteriorates
Solution Approach 1:
The patent replaces the manual mechanical system of swinging a heavy sledgehammer with a controlled actuation system. The opening tool incorporates a mechanism (such as a screw mechanism or lever system) that converts small input forces from the operator into large opening torque forces, eliminating the need for heavy striking tools and improving ergonomic performance.
3Force
If known opening tools with gear transmission or actuating cylinders are used, then opening torque can be generated, but the tools become large, heavy and complicated
Solution Approach 1:
The patent divides the opening tool into distinct functional segments: a bracket portion that engages with the lock ring, an actuator portion that generates the opening force, and a connection mechanism. This segmentation allows each component to be optimized independently, resulting in a simpler, lighter, and more manageable tool while still generating the necessary opening torque.
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
The tool provides a large opening torque while minimizing deformation risks and maintaining a lightweight, compact design, ensuring ease of use and safety.
Implementation Method 1
an opening torque is applied on the lock ring. The opening torque will loosen the screw connection between the lock ring and the lower separator bowl part
Implementation Method 2
at least one actuator connected to the first tool part and to the second tool part, which actuator is configured to move the first tool part and the second tool part towards each other or from each other in order to release the lock ring
