Powered Hydraulic Release Valve Assembly for Fast Jack Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic jacks require manual operation of hydraulic fluid release valves, which is cumbersome and inefficient, especially when dealing with high-pressure hydraulic fluid, and electrically powered jacks maintain constant fluid supply regardless of load, leading to slow lifting speeds for light loads.
Innovation Solution
Hydraulic fluid release valve assemblies with an electrically powered driving mechanism and a two-stage valve pin, along with hydraulic piston pump assemblies featuring multiple pistons with varying displacement volumes and pressure settings, allowing for efficient and adaptive fluid control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of hydraulic fluid release valve is used, then device complexity is reduced, but ease of operation deteriorates and productivity decreases
Solution Approach 1:
The patent replaces the manual mechanical operation of the release valve with an electrically powered driving mechanism. The electric driver (motor) converts electrical energy to mechanical rotation, which through the drive mechanism (gears, cam, or linkage) actuates the release valve automatically, eliminating the need for manual twisting or turning operations.
Solution Approach 2:
The system enables automatic control of the release valve through the electrically powered driving mechanism, allowing the hydraulic jack to control its own fluid release without requiring external manual intervention. The electric driver automatically actuates the valve based on control signals, making the system self-sufficient in valve operation.
2Productivity
If constant fluid supply is maintained for heavy loads, then lifting capability is improved, but lifting speed becomes too slow for light loads
Solution Approach 1:
The patent employs a dual piston pump system where the pump can dynamically switch between different piston configurations. A first piston with larger displacement volume provides high flow rate for light loads (fast lifting), while a second piston with smaller displacement volume provides high pressure for heavy loads. The system adapts the pumping characteristics in real-time based on load conditions, achieving both speed and power when needed.
Solution Approach 2:
The pump is segmented into two distinct piston systems with different displacement volumes and pressure capabilities. This segmentation allows the system to selectively engage different pistons based on operational requirements, enabling the hydraulic jack to optimize performance across varying load conditions rather than relying on a single fixed-displacement pump.
3Productivity
If manual power is used to open release valve against high pressure, then device complexity is reduced, but loss of time increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical operation of the release valve with an electrically powered driving mechanism. The electric driver (motor) converts electrical energy to mechanical rotation, which through the drive mechanism (gears, cam, or linkage) actuates the release valve automatically, eliminating the need for manual twisting or turning operations and significantly reducing the time required for valve actuation.
Solution Approach 2:
The patent introduces an electrically powered driving mechanism as an intermediary between the control system and the release valve. This intermediary component (electric driver with drive mechanism) provides the necessary mechanical force to quickly overcome high hydraulic pressure and actuate the valve, serving as a mediator that translates electrical control signals into rapid mechanical valve operation without requiring direct manual intervention.

AI summary
Hydraulic fluid release valve assemblies are described herein. The hydraulic fluid release valve assemblies may include a hydraulic unit base with a hydraulic fluid return channel and a hydraulic fluid release valve that is at least partially inserted in the hydraulic fluid return channel. The hydraulic fluid release valve assembly may further include a driving assembly to contact with the hydraulic fluid release valve to apply a pushing force on the hydraulic release valve to open the hydraulic fluid release valve, and an electrically powered driver connected to the driving assembly, the electrically powered driver, when actuated, causes the driving assembly to move to apply the pushing force to the hydraulic fluid release valve.
