Solution Overview

Problem

Conventional hydraulic jacks, such as bottle jacks, are limited to a single upright orientation for lifting and become inoperable when tilted, sideways, or upside down, restricting their utility.

Innovation Solution

A hydraulic cylinder design with an outer and inner cylinder, a piston, and a movable tube within the reservoir allows continuous hydraulic fluid flow to the piston cavity from any orientation, enabling lifting in tilted, sideways, and upside-down positions through a pump system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hydraulic cylinder uses a fixed conduit for hydraulic fluid flow, then the structure is simple, but the jack becomes inoperable when tilted, sideways, or upside down

Engineering Contradiction:

Improveoperability in multiple orientationsVSAvoidconduit structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conduit is made movable within the reservoir instead of being fixed, allowing it to dynamically reposition itself based on the cylinder's orientation. This dynamic adjustment enables the free end to always reach the lowest point of the reservoir, maintaining hydraulic fluid flow capability in any orientation while keeping the overall structure relatively simple.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable conduit utilizes gravity and fluid pressure to automatically position its free end at the lowest point of the reservoir regardless of the cylinder's orientation. This self-positioning mechanism eliminates the need for complex external control systems, achieving adaptability through the system's own physical properties.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the hydraulic cylinder is designed for upright orientation only, then the design is simple, but the utility is limited

Engineering Contradiction:

Improveoperational flexibilityVSAvoiddesign complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The hydraulic cylinder is designed to perform the same lifting function in multiple orientations (upright, tilted, sideways, upside down) through the movable conduit mechanism. This multi-functional capability allows a single device to replace what would traditionally require multiple orientation-specific jacks, improving utility without proportionally increasing manufacturing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is disclosed a jack that provides lifting from multiple orientations or directions. The jack is able to provide the lifting from these multiple orientations as fluid is continuously transferred from a reservoir to a pumping chamber to a piston chamber, regardless of the orientation or direction of the jack.
