Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic cylinder drainage systems in turbomachines fail to effectively evacuate hydraulic fluid leaks across varying positions and inclinations of the turbomachine, leading to potential contamination and performance degradation.
Innovation Solution
A hydraulic device with two drainage ducts oriented in different directions, ensuring effective evacuation of internal leaks regardless of position, with the ducts communicating inside the device and capable of directing leaks outside by gravity, reducing the need for multiple specific designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single drainage duct is used in the hydraulic device, then the device complexity is reduced, but the reliability of leak evacuation deteriorates when the turbomachine operates at varying inclinations
Solution Approach 1:
The drainage system is segmented into multiple independent drainage ducts (first drainage duct and second drainage duct) oriented in different directions. Each duct can independently evacuate leaks based on the device's orientation, ensuring reliable leak evacuation across varying turbomachine inclinations without requiring a complex centralized system.
Solution Approach 2:
The drainage ducts are oriented in different spatial directions (different dimensions) to accommodate varying gravitational vectors when the turbomachine operates at different inclinations. This dimensional diversification ensures that at least one drainage path remains effective regardless of the device's orientation.
2Adaptability or versatility
If multiple specific hydraulic device designs are created for different architectures, then the adaptability to various positions is improved, but the manufacturing complexity and production costs increase
Solution Approach 1:
A single hydraulic device design incorporates multiple drainage ducts oriented in different directions, enabling it to function effectively in various positions and architectures. This universal design eliminates the need to manufacture multiple specific designs for different applications, thereby maintaining adaptability while simplifying production.
Solution Approach 2:
The drainage ducts are configured with different orientations (parameter changes in spatial arrangement) within a single device design, allowing the same device to adapt to various installation positions and architectural configurations without requiring design modifications or multiple manufacturing processes.
