Solution Overview

Problem

The process of disassembling and reassembling cranes for relocation is time-consuming and costly, often taking days to weeks, causing delays and increased operating costs due to the need to lower or remove the boom arm to avoid obstructions like electrical lines.

Innovation Solution

A vehicle with a platform that supports and stabilizes the crane's boom arm during relocation, allowing it to remain assembled by lowering it to a horizontal position for transport, using hydraulic lift systems and sensors for precise positioning and alignment, enabling the crane to be moved without disassembly, thus reducing relocation time and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the crane boom arm is kept assembled during relocation, then the relocation time is reduced, but the crane cannot pass under electrical lines and other obstructions

Engineering Contradiction:

Improverelocation timeVSAvoidcollision with electrical lines

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The boom arm is made dynamically adjustable between vertical and horizontal positions through hydraulic control systems. This allows the crane to maintain the boom arm in a horizontal position during relocation to pass under obstructions, then raise it to vertical position at the destination, resolving the contradiction between keeping the boom assembled and avoiding collisions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spatial orientation parameter of the boom arm is changed from vertical to horizontal position during relocation. By controlling the boom arm's angular position parameter, the crane can pass under electrical lines without disassembly, thereby reducing relocation time while avoiding collisions.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the boom arm is disassembled for relocation, then the crane can pass under obstructions, but the relocation process takes days to weeks

Engineering Contradiction:

Improvecollision with electrical linesVSAvoidrelocation time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The hydraulic control system enables dynamic positioning of the boom arm, allowing it to be lowered to a horizontal position for transport under obstructions and raised to vertical position at the destination, eliminating the need for disassembly and reducing relocation time from days to hours.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The manual disassembly and reassembly mechanical process is replaced by a hydraulic control system that can lower and raise the boom arm remotely. This substitution reduces relocation time significantly while maintaining the ability to pass under obstructions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of time

If the boom arm is lowered to horizontal position for transport, then the crane can move without disassembly, but the boom arm may become unstable

Engineering Contradiction:

Improverelocation timeVSAvoidboom arm stability

Core Design Contradiction:

Loss of timeVSStability of the object's composition

Solution Approach 1:

Support structures act as intermediaries to stabilize the boom arm when positioned horizontally during transport. These support mechanisms provide additional stabilization points that prevent the boom arm from becoming unstable in its lowered position, enabling safe relocation without disassembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system incorporates stabilization measures that are activated before and during the horizontal positioning of the boom arm. By preparing support structures in advance and maintaining them during transport, the boom arm's stability is ensured throughout the relocation process.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A vehicle may be configured with an adjustable horizontal planar platform for receiving a load, such as a boom arm of a crane and transporting the load to a new location. In some cases, the platform is configured to swivel and tilt in order to maintain an alignment with a second vehicle during transport of a load.
