Switchable Pressure Booster for On-Demand Hydraulic Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic systems often require a pressure booster to amplify pressure, but this is not always necessary, leading to inefficiencies and increased energy consumption when the booster is active all the time.
Innovation Solution
A hydraulic system with an inactivating means, such as a valve, that connects a signal line to both the booster input and output, allowing the pressure booster to be activated only when needed, using a differential piston for amplification and an auxiliary pump for additional pressure when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the pressure booster is permanently active to amplify pressure, then the output pressure is sufficient for high-demand hydraulic consumers, but the energy consumption increases and the system operates inefficiently during normal operations
Solution Approach 1:
The pressure booster is designed to be dynamically switchable between active and inactive states through a control valve. The valve can redirect hydraulic fluid to either activate the booster (when high pressure is needed) or bypass it (during normal operations), making the system adaptable to varying pressure demands and reducing unnecessary energy consumption.
Solution Approach 2:
The pressure booster operates periodically rather than continuously, being activated only when the control valve detects that high pressure is required. This on-demand operation pattern reduces energy consumption while ensuring sufficient pressure is available when needed.
2Reliability
If the pressure booster is always active to ensure sufficient pressure, then the hydraulic consumer can always operate at required pressure levels, but the system cannot operate efficiently with lower pressure during normal conditions
Solution Approach 1:
The system dynamically adjusts the pressure booster's operational state based on real-time pressure demands. The control valve monitors system requirements and switches the booster between active and inactive modes, ensuring reliable pressure supply when needed while maintaining operational efficiency during normal conditions.
Solution Approach 2:
The control valve automatically determines when the pressure booster should be activated or deactivated based on system pressure requirements, enabling the system to self-regulate and optimize its operation without external intervention.
3Use of energy by moving object
If the pressure booster is inactivated to reduce energy consumption, then the system operates efficiently with lower pressure, but the hydraulic consumer cannot receive elevated pressure when needed
Solution Approach 1:
The control valve incorporates feedback mechanisms that monitor system pressure requirements and automatically activate the pressure booster when elevated pressure is detected as necessary. This feedback loop ensures that the booster is activated only when needed, maintaining energy efficiency while ensuring pressure sufficiency.
4Adaptability or versatility
If a valve is added to control the pressure booster activation, then the system gains pressure on demand capability, but the device complexity increases
Solution Approach 1:
A control valve is introduced as an intermediary component between the pressure source and the pressure booster. This valve acts as a simple switching mechanism that directs hydraulic fluid flow to activate or deactivate the booster, adding minimal complexity while enabling flexible pressure control and on-demand operation.
