Solution Overview

Problem

Existing machinery for handling elongated loads, such as tube bundles, in industrial settings is either operationally complex for larger loads or lacks structure for smaller loads, compromising safety for operators.

Innovation Solution

A machine with a bearing slide and aerial suspension system, including a support plate, suspension ring, and actuator for balancing, along with a motor-driven transmission system for controlled sliding and coupling, allows for safe and efficient handling of loads by maintaining horizontal equilibrium and enabling precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If complex equipment is used for larger loads, then handling capability is improved, but operational complexity increases

Engineering Contradiction:
Improvehandling capabilityVSAvoidoperational complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The machine is divided into distinct functional modules: a bearing slide for load support, aerial suspension means for positioning, coupling means for load attachment, and dragging means for movement. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and reduced operational complexity.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If unstructured systems are used for smaller loads, then device complexity is reduced, but safety deteriorates

Engineering Contradiction:
Improvesystem structureVSAvoidoperator safety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The machine integrates multiple functions into a single unified system: the bearing slide provides both support and movement capability, the aerial suspension means handles both positioning and stabilization, and the coupling means ensures secure load attachment. This multi-functionality maintains operational safety while avoiding the need for multiple separate equipment pieces.

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

Solution Approach 2:

The bearing slide acts as an intermediary element between the aerial suspension system and the load, providing a stable interface that ensures safe load handling. The slide's structured design with proper bearing surfaces and coupling points maintains safety requirements while keeping the overall system appropriately complex for the task.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If manual handling methods are used, then equipment cost is reduced, but operator safety deteriorates

Engineering Contradiction:
Improveequipment structureVSAvoidoperator safety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The machine is designed to perform handling operations autonomously through its integrated systems. The dragging means with motor-driven transmission automatically moves the load along the bearing slide, the aerial suspension means automatically positions and stabilizes the load, eliminating the need for manual handling operations and associated safety risks while maintaining reasonable equipment complexity.

Inventive Principle:
Principle #25Self-service
