Solution Overview

Problem

The existing buckstay connecting system for furnaces requires excessive welding and temporary construction materials to prevent horizontal buckstays from falling, leading to increased construction time and cost, as vertical buckstays slide relative to horizontal buckstays due to thermal expansion, necessitating additional support during installation.

Innovation Solution

A buckstay connecting system featuring a socket part fixed to the horizontal buckstay and an insertion part that slides vertically, allowing for bolt-fastening to secure the vertical buckstay to the socket part, reducing the need for temporary supports and welding, with bolt insertion holes for easy alignment and fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If vertical buckstays are welded and fixed to horizontal buckstays, then connection strength is improved, but welding work burden increases

Engineering Contradiction:
Improveconnection strengthVSAvoidwelding work burden
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The connection system is divided into separate components: a socket part fixed to the horizontal buckstay and an insertion part fixed to the vertical buckstay. This segmentation eliminates the need for welding between buckstays while maintaining connection strength through the insertion-socket mechanism with bolt fastening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The socket part acts as an intermediary component that mediates the connection between horizontal and vertical buckstays. Instead of directly welding the buckstays together, the insertion part of the vertical buckstay inserts into the socket part, providing a strong connection without welding.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If temporary construction materials are installed to support horizontal buckstays, then prevention of horizontal buckstay falling is improved, but construction material quantity increases

Engineering Contradiction:
Improveprevention of horizontal buckstay fallingVSAvoidconstruction material quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The socket part is preliminarily fixed to the horizontal buckstay during factory assembly, and the insertion part is preliminarily fixed to the vertical buckstay. This preliminary preparation eliminates the need for temporary construction materials during installation, as the connection components are ready for immediate assembly.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The buckstay connection system is self-supporting through the insertion-socket mechanism. The vertical buckstay's insertion part automatically provides support to the horizontal buckstay through the socket part, eliminating the need for external temporary construction materials.

Inventive Principle:
Principle #25Self-service

3Reliability

If socket parts are welded to horizontal buckstays in construction field, then connection reliability is improved, but construction period increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconstruction period
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The socket part is preliminarily welded to the horizontal buckstay in the factory before construction site assembly. This preliminary action transfers the welding work to the factory setting, reducing construction period while maintaining connection reliability through pre-fabricated quality control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The connection system is segmented into factory-prepared components (socket part welded to horizontal buckstay) and site-assembled components (insertion part inserted into socket part). This segmentation moves time-consuming welding operations to factory production, shortening the construction period.

Inventive Principle:
Principle #1Segmentation

AI summary

A buckstay connecting system includes a socket part that is fixed to the horizontal buckstay being separated from a lower end of the vertical buckstay between the lower end of the vertical buckstay and the horizontal buckstay, and an insertion part that is fixed to a lower portion of the vertical buckstay, is inserted into the socket part so as to be able to slide in a vertical direction, inhibits the horizontal buckstay from being inclined, and is allowed to be fastened to the socket part.
