Solution Overview

Problem

The existing machine tools for processing panel-shaped materials, particularly in the furniture sector, are complex and require numerous processing steps, limiting efficiency and effectiveness in machining large-format panels.

Innovation Solution

A machine tool with a first and second machine table, a processing portal guided on both sides, and a lifting device with individually controllable suction cups, enabling fully automatic sequential processing of large-format panels, including cutting, milling, and drilling, with vertical and horizontal processing capabilities, and a support device for further processing on a conveyor belt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of processing steps are used to process panels, then the functionality and processing capability are improved, but the complexity of the machine tool increases

Engineering Contradiction:
Improveprocessing capabilityVSAvoidmachine complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple processing functions (sawing, drilling, milling, sanding) into a single integrated processing portal that can service both machine tables. This merging of functions reduces overall machine complexity while maintaining versatile processing capabilities through a unified tool carrier head that can perform multiple operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The processing portal is designed as a universal device that can perform multiple processing operations (cutting, drilling, milling, sanding) and can service both the first and second machine tables. The tool carrier head contains multiple tools that can be positioned to perform different functions, making the system multi-functional without requiring separate dedicated machines for each operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If panels are processed manually or in separate steps, then the machine structure is simpler, but the productivity and processing efficiency decrease

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidmachine structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enables continuous processing by having the processing portal move between the first and second machine tables without interruption. Panels are processed on the first table, then automatically transferred to the second table for additional processing operations. This continuous action eliminates idle time and manual intervention, significantly improving productivity while the automated portal management keeps the structural complexity manageable.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The processing portal is designed to be movable and dynamically repositionable between the two machine tables. The portal can be positioned over either table as needed, and the tool carrier head can dynamically adjust its position and orientation to perform different operations. This dynamic capability allows the system to adapt to different processing requirements without requiring a completely reconfigured machine structure.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a processing portal is made movable to service both tables, then the versatility is improved, but the stability and precision of machining may worsen

Engineering Contradiction:
Improveprocessing versatilityVSAvoidmachining precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The system is segmented into two separate machine tables, each with its own suction cup-based workpiece holding system. The processing portal acts as a mobile service unit that can position itself over either table. This segmentation allows each table to maintain stable, precise machining conditions for its specific operations, while the portal provides versatile access to both tables without compromising the precision of either location.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If suction cups are controlled individually, then the adaptability to different panel sizes is improved, but the control system complexity increases

Engineering Contradiction:
Improvepanel size adaptabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The suction cups are arranged in arrays on both machine tables, with each suction cup or group of suction cups capable of being independently controlled. This local quality control allows the system to adapt to different panel sizes and shapes by activating only the suction cups needed to hold the specific workpiece being processed. The individual control capability provides high adaptability while the modular nature of the suction cup arrays keeps the control system complexity manageable through standardized control units.

Inventive Principle:
Principle #3Local quality
