Solution Overview

Problem

Woodworking machines with one-dimensionally adjustable guide devices have a limited range of variants for processing wood profiles, particularly those with complex shapes like steps and curves, which restricts the variety of geometries that can be machined safely and accurately.

Innovation Solution

A guide device with adjustable height and width, featuring movable guide means that can engage and overlap transversely to the conveying direction, including stationary and adjustable vertical and lateral guides, and rotatable rollers, allowing for precise guidance of workpieces with varying sizes and orientations, ensuring safe and accurate processing of complex profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If one-dimensionally adjustable guide devices are used, then the structure is simple, but the range of variants for processing wood profiles is limited

Engineering Contradiction:
Improverange of variants for processing wood profilesVSAvoidguide device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide device employs two-dimensionally adjustable guide means that can be positioned in different locations and orientations, allowing dynamic adaptation to various wood profile geometries including complex shapes with steps and curves, thereby resolving the contradiction between versatility and structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent transitions from one-dimensional adjustment to two-dimensional adjustment of guide means, enabling the guides to engage workpieces from multiple directions (front, rear, left, right sides), which significantly expands the range of processable profile variants while maintaining reasonable structural complexity

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

2Adaptability or versatility

If guide means are movable relative to one another, then the adjustment range is enlarged, but the device complexity increases

Engineering Contradiction:
Improveadjustment rangeVSAvoidguide means configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide device is divided into multiple independent guide means (front, rear, left, right guides) that can be adjusted separately in two dimensions, allowing each segment to be optimized for specific workpiece portions while collectively providing comprehensive guidance for diverse geometries

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each guide means is designed with universal two-dimensional adjustability, enabling the same guide component to serve multiple functions across different workpiece sizes and shapes, thereby enlarging the adjustment range without proportionally increasing overall device complexity

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

3Area of stationary object

If guide elements are arranged on slender support arms with gaps, then the feed area is enlarged, but the guidance stability may be reduced

Engineering Contradiction:
Improvefeed areaVSAvoidguidance stability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The guide elements on slender support arms are designed to be movable and adjustable, dynamically adapting their positions to provide stable guidance despite the reduced structural rigidity from gaps and slender supports, thereby maintaining reliability while enlarging the feed area

Inventive Principle:
Principle #15Dynamics
