Solution Overview

Problem

Existing edgebanding machines for wood panels require significant maintenance and long setup times when switching between glues of different colors or chemical-physical characteristics, due to the need for emptying, cleaning, and refilling the glue tank.

Innovation Solution

The machine features a glueing roller that can be rapidly replaced with a new glue supply by a feeding unit, which includes a tank and a spray dispenser, allowing for quick switching between different glues without removing the roller from the machine, and optionally incorporates a cleaning device and multiple feeding units with varying glues controlled by an electronic unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single glue tank is used for edgebanding, then the device structure is simple, but the setup time and maintenance cost increase when switching between different glues

Engineering Contradiction:
Improvestructure simplicityVSAvoidsetup time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent divides the glue supply system into multiple independent feeding units (18, 23), each capable of holding different glue types. This segmentation allows quick switching between glues by simply changing which feeding unit is active, rather than emptying and cleaning a single tank, thus reducing setup time while maintaining reasonable structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The glueing roller (12) is designed to be universally compatible with multiple glue types and feeding units. The roller can rapidly accept glue from different feeding units without requiring modification or extensive cleaning, enabling multi-functionality that reduces both setup time and maintenance costs when switching between different glue colors or chemical-physical characteristics

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

2Device complexity

If a single glue tank is used for edgebanding, then the device structure is simple, but the maintenance cost increases when switching between different glues

Engineering Contradiction:
Improvestructure simplicityVSAvoidmaintenance cost
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

By segmenting the glue supply into multiple feeding units that can be independently selected, the system eliminates the need for complete tank emptying and cleaning when switching glue types. This reduces maintenance workload and costs while keeping the overall structure relatively simple through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implies that feeding units can be quickly replaced or reset rather than requiring thorough cleaning of a permanent tank. This approach treats the glue containment as more temporary/disposable in nature, reducing maintenance costs by avoiding expensive cleaning operations while maintaining acceptable structural complexity

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If multiple feeding units with different glues are used, then the productivity increases by reducing setup time, but the device complexity increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is segmented into multiple independent feeding units that can be quickly switched between, enabling rapid glue changes without extensive setup time. This segmentation improves productivity by allowing operators to simply switch between pre-filled units rather than cleaning and refilling a single tank, while the modular nature keeps complexity manageable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The glueing roller system is designed to automatically or semi-automatically adapt to different glue types from different feeding units. The rapid replacement capability and electronic control suggest a degree of self-service where the system manages the complexity of multiple glue types without requiring proportionally complex manual intervention, thus improving productivity while controlling overall device complexity

Inventive Principle:
Principle #25Self-service

AI summary

In a machine for edgebanding wood panels (2) or the like, each panel (2) is edgebanded with a finishing edge (11) applied onto the panel (2) by an edgebanding assembly (10) provided with a tank (19; 24) for containing glue, a glueing roller (12) completely fitted on the outside of the tank (19; 24) for applying the glue onto the finishing edge (11) and/or the panel (2), and a feeding device (20; 25) for transferring the glue from the tank (19; 24) to the glueing roller (12).
