Solution Overview

Problem

The manual and inefficient process of shaping refractory bricks for kilns and furnaces results in high exposure to silicate dust, inconsistent brick dimensions, and difficulty in achieving tight seals, leading to inefficiency and potential damage.

Innovation Solution

An automated refractory brick production system that includes an infeed component for orientation, quality control for inspection and rejection, planing for uniform height, machining for shape, beveling, and a transfer system with robotic arms for precise brick handling, all controlled by a programmable system to produce bricks with high tolerances and reduce dust exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual brick shaping is used, then flexibility in brick design is maintained, but operator exposure to silicate dust increases and manufacturing precision deteriorates

Engineering Contradiction:

Improvebrick dimension consistencyVSAvoidoperator exposure to silicate dust

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical brick shaping with an automated machining system that uses computer-controlled cutters to shape refractory bricks. This substitution eliminates operator exposure to silicate dust while maintaining precise control over brick dimensions and shapes, directly resolving the contradiction between manufacturing precision and harmful factor exposure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated machining is implemented, then manufacturing precision and productivity improve, but device complexity increases

Engineering Contradiction:

Improvebrick production efficiencyVSAvoidautomation system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The automated brick production system is divided into distinct functional modules: an infeed component for loading bricks, a quality control component for inspection, a planing component for surface finishing, a machining component for shaping, and a transfer system for moving bricks between stations. This segmentation allows each module to perform a specific function efficiently while simplifying the overall system architecture and maintenance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The machining component is designed with multiple cutters that can perform various operations (shaping, grooving, beveling) on different brick types using a single multi-functional station. The transfer system also handles multiple brick orientations and positions, reducing the need for multiple specialized devices and thereby managing device complexity while maintaining high productivity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If quality control inspection is added, then brick quality consistency improves, but production time increases

Engineering Contradiction:

Improvebrick quality consistencyVSAvoidinspection cycle time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The quality control component performs inspection of refractory bricks immediately after they are formed but before they enter the machining process. This preliminary action identifies defective bricks early, preventing wasted machining time on unsalvageable bricks and ensuring only quality bricks proceed through the production line, thereby maintaining quality consistency without significant time loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The quality control inspection is integrated into the continuous flow of the production line, with bricks moving automatically from the forming station to the inspection station and then to the machining station without interruption. This continuous operation minimizes idle time and maintains production rhythm while ensuring every brick is inspected for quality consistency.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A system for production of customizable refractory bricks in an automated fashion is described. The system receives refractory bricks, measures and performs quality control inspections and rejects out of specification bricks. The system planes the bricks to a consistent height and performs one or more machining operations to grind the bricks into a final shape before conveying the bricks for assembly in the order required for assembly rather than in a batch process.
