Solution Overview

Problem

Conventional vehicle jacks are laborious and time-consuming to relocate between the two sides of a vehicle, requiring repeated positioning and often necessitate users to climb underneath to achieve proper alignment, especially with newer vehicles having low chassis and varied designs.

Innovation Solution

An extendable vehicle jack with a horizontal frame featuring a rear section and a front section that can be telescopically extended using either hydraulic or pneumatic cylinders, allowing the lifting mechanism to be variably positioned beneath the vehicle without relocating the jack, equipped with swiveling locking casters and a conventional scissors jack mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the jack is positioned closer to the middle of the vehicle to lift from a more central location, then the lifting position flexibility is improved, but the jack handle operation becomes improper and the jack becomes unstable

Engineering Contradiction:

Improvelifting position flexibilityVSAvoidjack handle operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The jack base is divided into a first base section and a second base section that can extend relative to each other. The first base section remains stationary while the second base section extends to provide additional support surface area when the jack is positioned closer to the vehicle center, maintaining stability without compromising handle operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base sections are configured to dynamically adjust their relative positions. The second base section can extend along the longitudinal axis of the jack when needed and retract when not required, allowing the jack to adapt its footprint based on positioning requirements while maintaining proper handle operation clearance.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the jack is relocated from one side of the vehicle to the other to lift both sides, then the complete vehicle lifting is achieved, but the time and labor required increases significantly

Engineering Contradiction:

Improvevehicle lifting efficiencyVSAvoidjack relocation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The extendable base section enables the single jack to perform multiple positioning functions. By extending the second base section, the jack can be positioned closer to the vehicle center to lift both sides simultaneously, eliminating the need to relocate the jack between sides and significantly improving productivity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base extension mechanism adds a longitudinal dimension adjustment capability to the jack base. This allows the jack to achieve proper lifting geometry for both sides of the vehicle by extending along the longitudinal axis rather than requiring lateral relocation, saving time and labor.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the jack base is kept compact for easy storage and mobility, then the storage and transport convenience is improved, but the positioning flexibility beneath the vehicle is reduced

Engineering Contradiction:

Improvestorage and mobility convenienceVSAvoidpositioning flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The second base section is designed to nest within or alongside the first base section when retracted, creating a compact configuration for storage and mobility. When positioning flexibility is needed, the second base section extends along the longitudinal axis, providing the necessary footprint adjustment without compromising compactness when not in use.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An extendable vehicle jack includes a horizontal frame having a rear section with a front section extendable therefrom. Within the front section is a lifting mechanism including a plate that engages the lower surface of the vehicle as it is being raised and lowered. The lifting mechanism includes a hydraulic pump and cylinder that expand and contract a scissors jack. The front section is automatically extended from the rear section with either a hydraulic or pneumatic cylinder. Accordingly, a worker can position the lifting mechanism any desired location beneath the vehicle frame.
