Solution Overview

Problem

Woodworking machines face challenges in maintaining a compact design while preventing chip contamination and damage between processing tables, as existing solutions either compromise on space or restrict tool diameters, limiting processing capacity and flexibility.

Innovation Solution

A movable separating element with its own drive is introduced between processing areas, allowing for variable separation and chip diversion to suction devices, enabling efficient chip management regardless of tool diameters and allowing for flexible processing area adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a compact design with two worktables is used, then installation space is reduced, but chip contamination between worktables increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidchip contamination
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The machining space is segmented into multiple independent machining areas by movable partition elements. Each machining area can be independently separated to prevent chip contamination while maintaining a compact overall machine structure. The partition elements divide the workspace into isolated zones where chips generated in one area cannot affect other areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Movable partition elements act as intermediary structures between machining areas. These partitions serve as physical barriers that prevent direct contact between chips from one worktable and workpieces or components on another worktable, thereby eliminating the contamination problem while preserving compact design.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If fixed separating elements are used, then chip contamination is prevented, but workpiece size limitations increase

Engineering Contradiction:
Improvechip contamination preventionVSAvoidworkpiece size range
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The partition elements are designed to be movable rather than fixed, allowing them to be repositioned or removed based on the size and type of workpiece being machined. This dynamic configuration enables the machine to handle a wide range of workpiece sizes while maintaining effective chip separation when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The separation parameters (position, extent, configuration of partitions) can be changed according to the specific machining requirements. This allows the machine to adapt to different workpiece dimensions and machining operations, eliminating the size limitations imposed by fixed separating elements.

Inventive Principle:
Principle #35Parameter changes

3Object-generated harmful factors

If chip deflectors mounted on spindles are used, then chip deflection is achieved, but tool diameter restrictions increase

Engineering Contradiction:
Improvechip deflectionVSAvoidtool diameter range
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The chip deflection function is extracted from the spindle/tool assembly and relocated to independent movable partition elements. This separation allows the chip deflection mechanism to operate independently of tool diameter constraints, as the partitions are not attached to or dependent on the machining tools.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The movable partition elements serve as universal chip deflection devices that can effectively manage chips generated by tools of various diameters. Unlike spindle-mounted deflectors that are limited by tool size, these independent partitions provide universal chip control across different tool types and sizes.

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

4Object-generated harmful factors

If extraction hoods are integrated, then chip extraction is improved, but installation space requirements increase

Engineering Contradiction:
Improvechip extraction efficiencyVSAvoidinstallation space
Core Design Contradiction:
Object-generated harmful factorsVSArea of stationary object

Solution Approach 1:

The chip extraction function is merged with the movable partition elements themselves. The partitions are designed to guide and concentrate chips toward extraction points, eliminating the need for separate, space-consuming extraction hoods while maintaining effective chip removal capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The chip extraction system is nested within the compact machine structure by integrating extraction functionality into the movable partition elements. This nested arrangement allows efficient chip extraction without requiring additional external extraction hoods that would increase installation space requirements.

Inventive Principle:
Principle #7Nested doll (Nesting)
