Solution Overview

Problem

The complexity of edgeband variants offered by furniture manufacturers leads to high storage requirements and inefficient production processes due to the need for multiple individual edgeband rolls, which are often not sufficient and require frequent exchange.

Innovation Solution

A roll of edgebanding tape with defined lengths composed of different partial lengths of varying edgebands, allowing customers to order specific combinations of type, length, and quantity, reducing storage needs and enabling just-in-time production by integrating multiple edgeband variants into a single roll.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple individual edgeband rolls are stored to offer various edgeband variants, then the variety of edgeband options is improved, but the storage requirements and device complexity increase

Engineering Contradiction:
Improvevariety of edgeband optionsVSAvoidstorage requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple different edgeband variants (varying in decor, geometry, material, consistency, surface properties, or layer structure) onto a single roll, creating an edgeband roll that integrates diverse edgeband types. This merging approach reduces the number of separate rolls needed while maintaining product variety.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single edgeband roll serves multiple functions by containing different edgeband variants that can cater to various customer requirements. The roll acts as a universal storage and supply unit that replaces multiple specialized rolls, enabling one roll to fulfill the role of several different edgeband supplies.

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

2Adaptability or versatility

If multiple individual edgeband rolls are exchanged frequently to meet production needs, then the adaptability to customer orders is improved, but the loss of time and productivity decrease

Engineering Contradiction:
Improveresponse to customer ordersVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By merging multiple edgeband variants into a single roll, the system eliminates the need for frequent roll exchanges during production. The combined roll allows continuous operation as different edgeband types are sequentially accessed from the same roll, reducing downtime and improving productivity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If finished edgebanding is stored at the customer's site, then the availability for immediate use is improved, but the storage requirements and production costs increase

Engineering Contradiction:
Improveavailability for immediate useVSAvoidstorage needs
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The edgeband variants are prepared and organized on a single roll in advance according to customer order specifications. This preliminary arrangement ensures that the required edgeband types are readily available for immediate use during production without requiring the customer to maintain large inventories of finished edgebanding materials.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to an edge strip roller. The aim of the invention is to simplify storage for customers who use the edge strip roller and who want to offer a plurality of different edge strips. Said aim is achieved by virtue of the fact that said edge strip roller has at least two different edge strips.
