Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filtering drilling fluids are inefficient and pose safety risks due to limited flow areas, large and expensive filter apparatuses, and time-consuming processes for installation and removal, which hinder safe and efficient operation of drilling rigs.
Innovation Solution
A flow line filter assembly with an inlet sub, outlet sub, and filter housing assembly, featuring a cylindrical body with an elongate slot and transverse side notch, allowing for quick and safe locking and removal of a filter locking sleeve and filter apparatus, enabling efficient filtration and debris removal without interrupting fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional filter apparatuses are used with limited flow areas, then filtration function is provided, but flow capacity is restricted and operational efficiency is reduced
Solution Approach 1:
The filter apparatus is divided into multiple filter elements that can be independently installed and removed. Each filter element has its own filtering function, and multiple elements can be arranged in parallel to increase total flow area while maintaining manageable individual components
Solution Approach 2:
The filter elements are arranged in a radial configuration around a central axis, utilizing the radial dimension to increase flow area without increasing the axial length. This allows multiple filter elements to be packed into a compact cylindrical space, effectively increasing flow capacity without proportionally increasing the footprint
2Productivity
If conventional filter apparatuses with large structures are used, then filtration capacity is increased, but device size and cost increase
Solution Approach 1:
Multiple filter elements are nested within a single housing structure, with each filter element fitting within the radial envelope of the housing. This nesting arrangement allows multiple filtering functions to be integrated into a compact overall structure, increasing capacity without linearly increasing device size
Solution Approach 2:
The filter elements are arranged radially around a central axis rather than linearly, utilizing the radial dimension to pack multiple filter elements into a compact cylindrical volume. This dimensional arrangement increases capacity while maintaining a compact footprint and manageable overall size
3Reliability
If conventional filter installation methods are used, then filtration is achieved, but installation and removal processes are time-consuming and interrupt fluid flow
Solution Approach 1:
The filter system is segmented into independently installable filter elements that can be individually replaced without affecting other elements. This segmentation allows for quick exchange of individual elements, minimizing the time required for maintenance operations and reducing interruptions to fluid flow
Solution Approach 2:
The filter elements are designed with dynamic installation features including external threads for easy screwing and unscrewing, and a locking mechanism that allows quick engagement and disengagement. These dynamic features enable rapid installation and removal operations without requiring complex assembly procedures or prolonged downtime
4Ease of repair
If conventional filter removal procedures are used, then filter更换 is possible, but safety hazards arise from dropping filters and personnel exposure
Solution Approach 1:
The filter system is divided into separate, handleable filter elements that can be independently grasped and removed. This segmentation allows personnel to safely handle individual elements without risk of dropping entire heavy filter assemblies, reducing safety hazards during the replacement process
Solution Approach 2:
A handle or gripping mechanism is provided as an intermediary between the personnel and the filter element. This handle allows safe grasping and controlled removal of the filter element, preventing direct hand contact with potentially hazardous surfaces and reducing the risk of drops and associated safety issues

AI summary
A method and apparatus for installing an object in a flow line or other compartment, such as a surface inline filter assembly having a removable screen filter apparatus. A housing has a central through bore and an elongate slot or opening with a cover that can be selectively opened or locked in a closed position when desired. A filter apparatus can be loaded within the assembly, and shifted into a locked position within the central bore of the housing. When removal of the filter apparatus is desired, the cover can be unlocked and opened, and the filter apparatus can be quickly and efficiently removed, cleaned and/or replaced.
