Solution Overview

Problem

Conventional panel dividing systems face challenges in achieving high dynamics and efficiently processing workpieces of different thicknesses due to the location of drives and the resulting moments that deform the pressure bar, leading to reduced efficiency and complexity in operation.

Innovation Solution

The panel dividing system features a drive located directly above the machine table with a crank mechanism and segmented pressure beams, each with independent mobility, reducing deformation moments and allowing for efficient movement and processing of workpieces of varying thicknesses, along with a conveyor device and dual pressure bars for effective dust management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the drive is located on the side of the machine table, then the structure is simpler, but the distance between the drive and the pressure bar increases, causing larger deformation moments and reduced dynamics

Engineering Contradiction:
Improvedrive structureVSAvoidpressure bar movement speed
Core Design Contradiction:
Device complexityVSSpeed

Solution Approach 1:

The drive is relocated from a lateral position to a central position directly above the machine table, changing the spatial dimension of the drive arrangement. This dimensional shift reduces the moment arm distance between the drive and the pressure bar, thereby reducing deformation moments and improving movement dynamics while maintaining structural simplicity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the pressure bar is made heavier and more rigid to reduce deformation, then the dynamics and speed of movement are reduced

Engineering Contradiction:
Improvepressure bar rigidityVSAvoidpressure bar movement speed
Core Design Contradiction:
Stability of the object's compositionVSSpeed

Solution Approach 1:

The drive is positioned centrally above the machine table before the cutting operation begins, creating a favorable geometric arrangement that minimizes the moment arm. This preliminary positioning allows the pressure bar to be lighter and more dynamic while still maintaining sufficient rigidity during operation, as the deformation moments are reduced by the optimized drive location

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a single pressure bar is used, then the structure is simpler, but workpieces of different thicknesses cannot be processed reliably

Engineering Contradiction:
Improvepressure bar structureVSAvoidworkpiece thickness adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The pressure bar is divided into multiple segments that can move independently of each other in the vertical direction. This segmentation allows each segment to adapt to workpieces of different thicknesses individually, enabling reliable processing of varied workpieces while maintaining a relatively simple overall structure

Inventive Principle:
Principle #1Segmentation

4Speed

If multiple partial drives are used to reduce deformation moments, then the dynamics improve, but the device complexity increases

Engineering Contradiction:
Improvepressure bar movement dynamicsVSAvoiddrive system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

Multiple partial drives are merged into a single centralized drive unit located above the machine table. This unified drive position allows the system to achieve the benefits of multiple drives (reduced deformation moments) while avoiding the complexity of multiple separate drive mechanisms, as all drives operate from a common location

Inventive Principle:
Principle #5Merging (Combining)
