Solution Overview

Problem

Existing lining systems for incinerator tube walls are complex, time-consuming, and lack stability and reliability due to the use of single-point attachments for refractory tiles, leading to potential instability and frequent replacement needs.

Innovation Solution

A lining system featuring refractory tiles with horizontal channels that hinge onto horizontal rails, providing multiple connection points and allowing for stable, reliable attachment through horizontal channels and rails, ensuring tiles remain in place even if one connection fails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual attachment per refractory tile is used, then fixation is achieved, but lining complexity and installation time increase

Engineering Contradiction:
Improvefixation stabilityVSAvoidlining complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple individual attachments are merged into a single horizontal rail structure that spans across multiple tiles. The rail integrates multiple connection points and attachment mechanisms into one unified component, reducing the number of separate parts and simplifying the overall lining system while maintaining reliable fixation for each tile.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The horizontal rail serves multiple functions simultaneously: it provides fixation for multiple refractory tiles, enables vertical adjustment, allows for easy installation and removal, and maintains stable positioning. This multi-functional design replaces the need for separate specialized components for each function, reducing system complexity.

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

2Reliability

If individual attachment per refractory tile is used, then fixation is achieved, but installation time increases

Engineering Contradiction:
Improvefixation stabilityVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The horizontal rail is pre-assembled with multiple connection points and attachment mechanisms before installation. This preliminary preparation allows for rapid installation of multiple tiles simultaneously, as the rail structure is already configured to receive and secure several refractory tiles in one operation, significantly reducing total installation time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Multiple fixation operations are combined into a single installation process. By integrating multiple attachment points into one horizontal rail, the system allows several tiles to be fixed simultaneously rather than requiring sequential installation of individual attachments, thereby increasing installation productivity.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If single connection point is used, then simplicity is maintained, but stability and reliability decrease

Engineering Contradiction:
Improveconnection simplicityVSAvoidlining stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The connection system is segmented into multiple independent connection points distributed along the horizontal rail. Each connection point can independently secure a refractory tile, and the distribution of multiple points along the rail provides redundant support, enhancing overall stability and reliability while maintaining relative simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The horizontal rail structure provides beforehand cushioning by distributing the load and stress across multiple connection points. This redundant structure ensures that if one connection point fails or experiences excessive stress, the other points continue to provide support, preventing catastrophic failure and maintaining lining stability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Reliability

If complex attachment system is used, then stability is improved, but maintenance frequency increases

Engineering Contradiction:
Improvelining stabilityVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The horizontal rail system incorporates dynamic adjustment capabilities that allow for easy modification and repositioning of refractory tiles. The attachment mechanism can be quickly adjusted or reconfigured without requiring complete disassembly, enabling rapid maintenance and repair operations while maintaining stable fixation during normal operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system is designed to facilitate self-service maintenance, where operators can easily access, remove, replace, or adjust refractory tiles and the horizontal rail structure without requiring complex tools or specialized procedures. The simplified attachment and detachment mechanisms enable maintenance personnel to perform repairs quickly and efficiently.

Inventive Principle:
Principle #25Self-service
