Solution Overview

Problem

Existing drive devices for continuous casting plants require complex construction, assembly, and adjustment due to individually screwed components, leading to high procurement and assembly costs, as well as difficulty in component replacement.

Innovation Solution

A modular drive device comprising a gear unit, clutch, and drive motor connected via a bell, forming a compact unit that can be easily assembled and adjusted, with the gear unit consisting of a planetary gear and bell, and the motor connected to the gearbox, allowing for torque transmission and simplified attachment to a base plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If motors and gearboxes are individually bolted to a carrier or base plate, then each component can be independently assembled and replaced, but the design and assembly process becomes complex and time-consuming

Engineering Contradiction:
ImproveEase of assemblyVSAvoidConstruction complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the motor, clutch, and transmission unit into a single integrated drive unit that is pre-assembled and pre-adjusted as one module. This merging of components eliminates the need for complex individual assembly and adjustment of multiple separate parts, directly resolving the contradiction between ease of assembly and construction complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple separate components are used in the drive system, then functionality can be optimized for each component, but procurement costs and assembly costs increase

Engineering Contradiction:
ImproveFunctional performanceVSAvoidProcurement cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The integrated drive unit combines motor, clutch, and transmission into one standardized module that maintains full functional capabilities while reducing procurement costs through standardized manufacturing and reduced assembly requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The standardized drive unit design can be universally applied across different roller positions and configurations, serving multiple functions while maintaining consistent performance standards, thereby reducing overall system costs.

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

3Manufacturing precision

If components are individually mounted and adjusted, then precise positioning can be achieved, but adjustment effort and time are significantly increased

Engineering Contradiction:
ImprovePositioning precisionVSAvoidAdjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The drive unit is pre-assembled and pre-adjusted to precise specifications during manufacturing. This preliminary action ensures that when the unit is installed on the roller, it is already positioned and aligned correctly, eliminating the need for time-consuming on-site adjustment while maintaining precise positioning.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If a compact modular drive unit is used, then assembly is simplified and costs are reduced, but the integration of multiple components into one unit increases manufacturing complexity

Engineering Contradiction:
ImproveEase of assemblyVSAvoidManufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The drive system is segmented into standardized modular units, each containing integrated components. This segmentation allows the complex integration to be performed once during module manufacturing, then the complete modules are easily assembled and replaced as single units, transferring manufacturing complexity to a controlled production environment.

Inventive Principle:
Principle #1Segmentation
