Solution Overview

Problem

Existing cutting stations for profiled elements, such as window and door frames, face inefficiencies due to large and separate marking assemblies that disrupt the machining process, leading to increased timelines, costs, and maintenance issues.

Innovation Solution

A cutting station integrated with a compact laser marking assembly that can engrave identification marks directly on the profiled elements during or after cutting, eliminating the need for consumables like paper and ink, and allowing continuous operation without interrupting the machining process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional marking assembly is used, then identification marking can be performed, but the marking assembly requires large dimensions and must be placed at a distance from the cutting assembly, causing the machining process to be interrupted and increasing production timelines

Engineering Contradiction:
Improveidentification markingVSAvoidproduction timeline
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent integrates the marking assembly directly onto the cutting assembly, merging two previously separate functions into one unified device. This allows marking and cutting operations to occur simultaneously at the same location, eliminating the need to move the profiled element between separate stations and thus preventing interruptions in the machining process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cutting assembly is designed to perform multiple functions: both cutting operations and marking operations. By making the cutting assembly universal, the system eliminates the need for separate dedicated marking equipment, thereby maintaining cutting precision while improving overall productivity through continuous operation.

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

2Measurement precision

If a traditional marking assembly is used, then identification marking can be performed, but the marking assembly requires paper and ink consumables that need frequent replacement and maintenance, increasing costs and operational disruptions

Engineering Contradiction:
Improveidentification markingVSAvoidmaintenance cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent replaces the mechanical marking system (which uses paper labels and ink) with a laser-based marking system. The laser assembly generates laser beams that directly mark the profiled element without requiring physical consumables like paper or ink, thereby eliminating the need for frequent replacement and reducing maintenance costs associated with consumable management.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of using disposable consumables like paper labels and ink cartridges that require frequent replacement, the invention employs a durable laser assembly that can operate continuously without consumable replacement, significantly reducing long-term operational costs and maintenance requirements.

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

3Measurement precision

If a traditional marking assembly is used, then identification marking can be performed, but the marking assembly has numerous moving components that cause jams and functional drawbacks, increasing maintenance requirements

Engineering Contradiction:
Improveidentification markingVSAvoidoperational reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces the mechanical marking system with an optical laser-based system. The laser assembly has fewer moving components compared to traditional mechanical marking assemblies, which reduces the likelihood of jams and functional failures, thereby improving operational reliability and reducing maintenance requirements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If the marking assembly is placed at a distance from the cutting assembly, then the cutting tool movement is not hindered, but the profiled element must be further moved and positioned, increasing production timelines

Engineering Contradiction:
Improvecutting tool movementVSAvoidpositioning time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines the marking assembly and cutting assembly into a single integrated unit, allowing both operations to occur at the same location. This eliminates the need to move the profiled element between separate marking and cutting stations, thereby reducing positioning time and maintaining ease of cutting tool movement.

Inventive Principle:
Principle #5Merging (Combining)
