Solution Overview

Problem

The existing manufacturing process for material sheets, such as particle boards and MDF boards, is lengthy due to the need for edge profiling after the material has cooled down, requiring separate machines and additional processing steps.

Innovation Solution

The profiling of the composite strand is performed before it cools down, integrating a profiling device with a trimming device and allowing simultaneous coating, eliminating the need for separate post-processing machines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the composite strand is cooled down before profiling, then the material becomes more stable and easier to handle, but the production time increases significantly

Engineering Contradiction:
Improvematerial stabilityVSAvoidproduction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The profiling operation is performed as a preliminary action while the composite strand is still warm from the press, before the material cools down. This eliminates the need to wait for cooling before profiling, significantly reducing production time while the material remains sufficiently stable to be profiled.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If separate profiling devices and cooling mills are used, then the profiling can be performed after cooling, but the device complexity and system size increase

Engineering Contradiction:
Improveedge profiling qualityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The profiling device is integrated into the existing production line near the press outlet, combining the profiling function with the existing material handling system. This eliminates the need for separate cooling mills and multiple standalone profiling devices, reducing overall system complexity while maintaining profiling quality.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the composite strand is profiled after cooling, then the material is more stable for processing, but the coating process must wait until profiling is complete

Engineering Contradiction:
Improvematerial stabilityVSAvoidproduction speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Profiling is performed as a preliminary action while the material is still warm, before coating. This allows the coating process to immediately follow without waiting for the material to cool, enabling continuous processing and increasing production speed while the material remains stable enough for both operations.

Inventive Principle:
Principle #10Preliminary action

4Object-affected harmful factors

If traditional cooling and profiling sequences are used, then the material can be handled safely, but the overall manufacturing process becomes lengthy

Engineering Contradiction:
Improvematerial handling safetyVSAvoidprocessing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The profiling operation is performed as a preliminary action while the composite strand is still warm from the press, before the material cools down. This eliminates the need to wait for cooling before profiling, significantly reducing production time while the material remains sufficiently stable to be profiled.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a method and a system for producing material sheets, in which particles are pressed into a composite strand between two circulating belts in a continuous press under the application of heat, and the composite strand exiting the continuous press (2) is subsequently cut into material sheets of the desired size and provided with a profiling process to achieve a non-rectangular cross-section. To accelerate the manufacturing process, the profiling process is carried out in a profiling device (6) before the material sheets have cooled to ambient temperature.
