Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure relief valves in fluid systems lack the ability to effectively manage pressure across varying operating conditions, particularly in aircraft engines, leading to inefficiencies and potential overpressurization.
Innovation Solution
A fluid system with a lubricant reservoir and pressure relief system that includes a sensor system, a pressure relief valve, and a controller, which dynamically adjusts the valve's operation based on sensor data to manage pressure by varying the flow area of the valve opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional pressure relief valve is used, then the structure is simple, but the pressure regulation capability across varying operating conditions is insufficient
Solution Approach 1:
The patent applies dynamics by transitioning from a static pressure relief valve to a dynamically controllable system. The electronically controlled pressure relief valve adjusts its opening degree in real-time based on sensor feedback and controller commands, enabling adaptive pressure regulation across varying operating conditions while managing system complexity through electronic control architecture.
2Adaptability or versatility
If a fixed opening pressure relief valve is used, then the device complexity is low, but the ability to respond to changing operating conditions is poor
Solution Approach 1:
The patent implements feedback control by incorporating sensors that continuously monitor pressure and operating conditions, transmitting this data to a controller that adjusts the pressure relief valve opening accordingly. This closed-loop feedback mechanism enables the system to respond dynamically to changing operating conditions while maintaining manageable complexity through standardized control architecture.
3Measurement precision
If an electronically controlled pressure relief valve is implemented, then pressure regulation precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical pressure relief valve mechanisms with an electronically controlled system. Sensors and electronic controllers substitute for purely mechanical spring-loaded valves, enabling precise digital control of the pressure relief opening degree and achieving superior pressure regulation precision while managing complexity through electronic control systems.
