Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current handling systems for longitudinal construction elements like beams and columns are unsafe and inefficient, particularly when operating under the constraints of maintaining catenary wires, as they require large cranes with delicate boom control and risk collisions due to the complexity of suspending and reorienting beams in tight spaces.

Innovation Solution

A handling system featuring a telescopic arm assembly with pivot and rotation capabilities mounted on a vehicle, equipped with gripping means and remote control mechanisms, allowing for precise orientation and movement of longitudinal elements without the need for extensive crane lengths, enabling safer and faster handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional crane with a telescopic boom and sling is used to handle beams, then the beam can be suspended and moved in space, but the risk of collision with catenaries increases and the operation becomes very delicate

Engineering Contradiction:

Improvesafety of operationVSAvoidrisk of collision with catenaries

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of suspending the beam from above using a sling (conventional crane method), the invention supports the beam from below using a support beam with resting means. This inversion of the handling approach eliminates the risk of collision with overhead catenaries while maintaining full control over beam positioning and orientation.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention introduces a support beam as an intermediary device between the crane and the beam being handled. This support beam acts as a mediator that provides stable support from below, allowing the beam to be moved safely without direct suspension that could cause collision with overhead structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Length of moving object

If a crane of large capacity with a considerable length boom is used to raise the beam to appropriate height, then the beam can be positioned above catenaries, but the device complexity and equipment size increase

Engineering Contradiction:

Improveheight reach capabilityVSAvoidcrane boom length and capacity

Core Design Contradiction:

Length of moving objectVSDevice complexity

Solution Approach 1:

The handling system is segmented into multiple functional components: a base for mounting, a telescopic arm assembly with pivot and rotation capabilities, and a support beam with gripping means. This segmentation allows each component to be optimized independently, reducing the need for an excessively long boom while achieving the required height and positioning capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The telescopic arm assembly incorporates dynamic capabilities including telescopic extension, pivoting, and rotation about vertical and horizontal axes. These dynamic features enable the arm to reach required heights and positions without requiring a permanently extended boom, thus reducing overall device complexity and equipment size.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the beam is suspended from a sling and moved simultaneously in three directions of space, then the beam can be reoriented, but the control becomes very delicate and depends on operator competence

Engineering Contradiction:

Improvebeam reorientation capabilityVSAvoidcontrol difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention replaces the complex mechanical control of a suspended beam with a more intuitive support-based system. The support beam with gripping means provides stable mechanical support from below, allowing for easier control of beam orientation and position without the instability and complexity of suspending a load from above.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The support beam system is designed to inherently stabilize the beam during handling operations. The gripping means and support structure work together to automatically maintain beam stability and orientation, reducing the burden on the operator and eliminating the need for highly skilled manual control.

Inventive Principle:

Principle #25Self-service
