Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air starter systems face challenges in effectively lubricating components due to inefficiencies in delivering and controlling the lubricant within compressed fluid systems, which can impact the reliability and performance of engine starting operations.
Innovation Solution
A combination shuttle and lubricator valve system that integrates a shuttle valve and a lubricator valve within a single housing, allowing for precise control of compressed fluid flow and lubricant injection into the fluid stream, ensuring proper lubrication of engine starters by utilizing a shuttle valve piston and a lubricator valve piston that move between positions to manage fluid and lubricant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate shuttle valve and lubricator valve systems are used, then each valve can be optimized independently, but the overall system complexity increases and space requirements increase
Solution Approach 1:
The patent combines the shuttle valve and lubricator valve into a single integrated unit with a common housing, piston assembly, and control mechanisms. This merging eliminates the need for separate valve assemblies while maintaining the functional independence and optimization benefits of each valve type, thereby reducing overall system complexity and space requirements
2Reliability
If multiple separate valves are used, then each valve can be optimized for its specific function, but the housing space and system size increase
Solution Approach 1:
The patent implements a nested configuration where the lubricator valve piston and control mechanisms are positioned within the same housing and structural framework as the shuttle valve. The valves share common walls, mounting structures, and fluid passages, allowing one valve assembly to be effectively nested within or alongside the other, thereby optimizing space utilization while maintaining functional independence
3Ease of repair
If separate valve systems are used, then maintenance and repair of individual valves is simpler, but the overall system requires more components and assembly steps
Solution Approach 1:
The integrated valve assembly is designed with modular components that can be independently accessed, removed, and replaced. The shuttle valve and lubricator valve are positioned to allow separate maintenance access, and internal components such as pistons, springs, and seals are designed as replaceable modules, enabling simplified maintenance of individual valves while maintaining the benefits of integration during manufacturing
