Solution Overview

Problem

Conventional screw jacks are cumbersome to operate manually, especially in locations without access to electricity, and their motorized versions lack portability, making them ineffective in situations where electricity is not available, such as in remote areas or during emergencies.

Innovation Solution

A portable screw jack system that incorporates a hollow member with internal threaded screws and a socket for engaging a rotational tool, such as a power drill, to provide rotational capacity for lifting or lowering objects, including a cordless or rechargeable power drill for enhanced portability and use without direct electrical connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a screw jack is motorized with a plug-in electric motor, then the lifting operation is automated and easier to operate, but the portability is reduced and the device cannot be used in locations without electrical outlets

Engineering Contradiction:

Improveautomated lifting operationVSAvoidportability and usability without electrical outlets

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces the traditional manual mechanical operation (hand turning the screw) with a power drill providing rotational power. This substitution maintains portability while achieving automated operation, as the power drill is a portable tool that does not require fixed electrical outlets.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The screw jack is designed to be compatible with standard power drill sockets, making it universally operable with any power drill. This multi-functionality allows the same lifting mechanism to be used whether powered by a cordless drill, corded drill, or even manual operation, enhancing adaptability across different scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If manual operation of the screw jack is used, then the device remains simple and portable, but the operation becomes cumbersome and labor-intensive

Engineering Contradiction:

Improvesimplicity and portabilityVSAvoidmanual labor required

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a power drill as an intermediary tool between the operator and the screw jack mechanism. Instead of directly manually turning the screw, the operator uses the power drill to provide rotational force, significantly reducing physical effort while maintaining the simplicity of the overall system.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into two independent components: the screw jack lifting mechanism and the power drill. This segmentation allows the jack to remain simple and portable while delegating the labor-intensive rotation task to the power drill, combining the benefits of both approaches.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If frequent manual turning of the screw is required, then the basic mechanism remains simple, but the receiving end of the screw wears out unevenly and faster

Engineering Contradiction:

Improvesimplicity of mechanismVSAvoidscrew wear and durability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces direct manual mechanical turning with power drill operation. The power drill provides more controlled and consistent rotational force, reducing uneven wear on the screw threads while maintaining the simplicity of the screw jack mechanism itself.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
