Hydraulic Pressure Booster Bypass for Pressure-on-Demand Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic systems often require permanent activation of pressure boosters, leading to high energy consumption and inefficiency, as they cannot selectively provide pressure based on demand, and existing solutions either interrupt fluid supply completely or require manual operation.
Innovation Solution
A hydraulic system with a pressure booster that is activated only when needed, using a hydraulically operated inactivating means, such as a valve, to short-circuit the booster, allowing for 'pressure on demand' and integrating the pressure booster and inactivating means within the pressure source or near the output, enabling efficient energy use and variable pressure amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the pressure booster is permanently activated to provide elevated pressure to the output, then the hydraulic consumer can operate with higher pressure, but the energy consumption increases significantly
Solution Approach 1:
The pressure booster is designed to be dynamically controllable, switching between active and inactive states based on system demands. The inactivating means (valve) enables the booster to transition from a permanently active state to a selectively active state, optimizing energy consumption while maintaining required pressure levels.
Solution Approach 2:
The system changes the operational parameter of the pressure booster from continuous operation to demand-based operation. By using the inactivating means to control the booster's activation, the system adapts pressure amplification to actual needs, reducing energy consumption when high pressure is not required.
2Use of energy by moving object
If the pressure booster is inactivated by interrupting fluid supply, then energy consumption decreases, but the fluid supply to the consumer is completely interrupted
Solution Approach 1:
The hydraulic system is segmented into multiple pathways: a main fluid supply line and a bypass line with the pressure booster. The inactivating means selectively controls the booster pathway while maintaining the main supply line open, allowing independent control of pressure amplification without interrupting overall fluid supply to the consumer.
Solution Approach 2:
The inactivating means (valve) acts as an intermediary control element that selectively regulates flow to the pressure booster without blocking the main fluid supply path. This intermediary mechanism enables precise control of the booster's activation while maintaining continuous supply to the consumer through alternative pathways.
3Stress or pressure
If the pressure booster is used to amplify pressure, then the system can meet high pressure demands, but the system complexity increases due to additional control mechanisms
Solution Approach 1:
The inactivating means is designed to be automatically actuated by hydraulic pressure signals from the system itself, eliminating the need for external control mechanisms. The booster pathway is controlled by the system's own pressure conditions, reducing overall system complexity while maintaining pressure amplification capability.
Solution Approach 2:
The control mechanism uses hydraulic pressure signals and fluid-powered actuation instead of complex mechanical or electronic controls. The inactivating means is operated by hydraulic pressure differential, leveraging the system's own working fluid and pressure to control the booster, simplifying the control architecture.
4Use of energy by moving object
If the pressure booster is short-circuited to reduce energy consumption, then the system operates efficiently, but the pressure amplification function is lost
Solution Approach 1:
The pressure booster operates dynamically, switching between short-circuited (inactive) and active states based on system demands. The inactivating means enables this dynamic transition, allowing the booster to be short-circuited during normal operation to save energy and activated when pressure amplification is required, optimizing both energy efficiency and functional capability.

Function Achieved in This Case
