Solution Overview

Problem

Current cranes, lifts, and bridge construction equipment have limited horizontal stability, restricted usage, and high energy consumption due to vertical lifting mechanisms, and require extensive manual precision and long construction times, with most machines being specialized for bridging and not adaptable for other tasks.

Innovation Solution

A Multi-Purpose Load Lifting Work Platform (MPLLWP) with a pole-shaped structure supporting a work platform that can move in a curved path, stop at any position, and be used independently or cooperatively, equipped with wireless obstacle detection, a blocking device, and mobility features like wheels and pickets, allowing for versatile load handling and bridge assembly/disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If vertical lifting mechanism is used, then lifting function is achieved, but horizontal stability is poor and loads sway back and forth

Engineering Contradiction:
Improvehorizontal stabilityVSAvoidload sway
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent transitions from vertical-only lifting to a two-dimensional curved trajectory system. The work platform can move along a curved path that combines both vertical and horizontal movements, allowing the load to be positioned precisely in two dimensions while maintaining stability throughout the movement range.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system employs a dynamic curved trajectory mechanism that allows the work platform to move flexibly along a predetermined curved path. This dynamic movement capability enables the platform to achieve both lifting and horizontal positioning functions while maintaining load stability through controlled motion along the curve.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If single work platform is provided, then equipment structure is simple, but scope of use is limited

Engineering Contradiction:
Improvescope of useVSAvoidplatform configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional system where two work platforms can operate independently or cooperatively. Each platform can perform lifting tasks individually, or they can work together to handle larger loads or more complex positioning requirements, significantly expanding the scope of application while maintaining manageable structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If modular bridge construction is used, then assembly is achieved, but construction period is long and requires extensive manual precision operations

Engineering Contradiction:
Improveconstruction speedVSAvoidconstruction period
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system incorporates an automated driving mechanism that enables the work platform to move along the curved trajectory autonomously. This self-driven capability eliminates the need for extensive manual operations during bridge assembly, allowing modular components to be positioned automatically and precisely, thereby reducing construction time and labor requirements.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If specialized bridge machine is used, then bridging function is achieved, but adaptability for other tasks is limited

Engineering Contradiction:
Improvetask versatilityVSAvoidequipment specialization
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs a universal work platform system that can perform multiple functions including lifting, curved trajectory movement, and cooperative operation. This multi-functional capability allows the same equipment to be used for both bridge construction and general lifting tasks, eliminating the need for specialized bridge machines and reducing equipment complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention discloses a multi-purpose load lifting work platform or/and composite bridge structure, comprising a framework, at least one work platform, a drive mechanism, and an electrical control devices. One end of the pole-shaped structure is connected with the framework in a movable manner, and the other end of the pole-shaped structure is connected with the work platform in a movable manner, the work platform can run with the pole-shaped structure together. The work platform can run in a curve track relative to the framework by power, and can stop at any position in running track. This invention can provide two platforms working coordinately or a single platform working independently. The working area of the two platforms greatly exceeds that of the existing common equipment with a single platform. It can load bulky objects without sway, and can also be used as composite or assembly bridge structure.
