Solution Overview

Problem

The slats in laser/plasma/flame cutting machines are subject to contamination and wear, requiring frequent cleaning and replacement, which leads to significant maintenance costs and reduced production time.

Innovation Solution

Manufacturing the slats from a non-metal, non-flammable, heat- and fire-resistant laminated composite material comprising glass fibre and/or glass fabric with a resin, such as phenolic resin or unsaturated polyester resin, which reduces sintering of cutting effluent and extends the service life of the slats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If metal slats are used in the slats table, then the slats can support the metal object to be cut, but the slats are subject to contamination and wear from cutting effluent, requiring frequent cleaning and replacement

Engineering Contradiction:
Improveservice life of slatsVSAvoidcontamination and wear from cutting effluent
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies composite materials by manufacturing slats from laminated composite material comprising glass fibre and/or glass fabric with a resin (phenolic resin or unsaturated polyester resin). This composite structure provides heat resistance, fire resistance, and reduced sintering of cutting effluent, directly addressing the contamination and wear problems while maintaining structural integrity for supporting metal objects during cutting operations

Inventive Principle:
Principle #40Composite materials

2Productivity

If metal slats are used, then structural strength is provided, but sintering of cutting effluent accumulates on the slats, requiring frequent cleaning

Engineering Contradiction:
Improveproduction timeVSAvoidcleaning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The laminated composite material with glass fibre/glass fabric and heat-resistant resin significantly reduces sintering of cutting effluent compared to metal slats. This reduction in effluent accumulation directly decreases the frequency and time required for cleaning operations, thereby increasing overall production time and efficiency

Inventive Principle:
Principle #40Composite materials

3Temperature

If phenolic resin or unsaturated polyester resin is used in the laminated composite material, then the slats become non-flammable and heat-resistant, but the material must be engineered to resist laser/plasma/flame beam irradiation

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent combines glass fibre and/or glass fabric with phenolic resin or unsaturated polyester resin to create a composite material that simultaneously achieves non-flammability, heat resistance, and resistance to laser/plasma/flame beam irradiation. The glass reinforcement provides structural stability and thermal resistance, while the specific resin selection ensures fire resistance and durability under intense thermal and radiant energy exposure

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent optimizes the chemical composition and physical structure of the laminated composite material by selecting specific resin types (phenolic or unsaturated polyester) and combining them with glass fibres/fabrics in particular configurations. This parameter optimization ensures the material maintains its mechanical properties and resistance characteristics under the extreme conditions of laser/plasma/flame cutting operations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The use of laminated composite materials significantly reduces sintering and accumulation of cutting effluent on the slats, leading to less frequent cleaning, extended service life, and reduced maintenance costs, thereby improving production efficiency.

Implementation Method 1

heat- and fire-resistant, durable, sturdy and dimensionally stable laminated composite material

Methodology Applied
Scientific EffectHeat resistance: Thermal Insulation

Implementation Method 2

non-flammable, heat- and fire-resistant, durable, sturdy and dimensionally stable laminated composite material comprising a mixture of glass fibre and/or glass fabric with a resin

Methodology Applied
Scientific EffectChemical inertness: Adsorption

Implementation Method 3

the ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Providing ceramic material improves the service time of the laminated composite material by enhancing the heat resistance and resistance to heat cutting

Methodology Applied
Scientific EffectHeat resistance enhancement: Thermal Insulation

Implementation Method 4

resulting in a reduction of wear, and of contamination by cutting effluent

Methodology Applied
Scientific EffectWear resistance: Wear

Implementation Method 5

at least a portion of the slat is sanded. It has been found, that a sanded surface contaminates less easily having the effect of less material sintering on the slat, and that also means that the resistance to heat cutting slightly improved

Methodology Applied
Scientific EffectSurface roughness effect: Abrasion
