Solution Overview

Problem

Plasma arc torches face challenges with incorrect consumable installation leading to poor cut quality, decreased cut speed, and premature consumable failure, as well as difficulties in manually configuring and optimizing torch operating parameters, especially when aftermarket consumables are used.

Innovation Solution

Incorporating readable data storage devices, such as RFID tags, on consumable components to automatically detect and communicate operating parameters to the torch system, allowing for semi-automated setup and optimization of cutting or welding processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration of torch operating parameters is used, then operator control is maintained, but setup time and complexity increase

Engineering Contradiction:
Improveease of consumable installationVSAvoidtime for manual parameter configuration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The consumable component automatically provides its identification information through an integrated data storage device (e.g., RFID tag) that the torch system reads upon installation. This self-service mechanism eliminates the need for manual parameter configuration by the operator, as the system automatically retrieves consumable-specific parameters from the data storage device.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The consumable component is pre-configured with identification data and operating parameters stored in a data storage device before installation. This preliminary action ensures that all necessary information is ready in advance, allowing the torch system to automatically configure itself without requiring manual setup during installation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If correct consumables are manually identified and installed, then optimal performance is achieved, but operator expertise and time are required

Engineering Contradiction:
Improveconsumable compatibilityVSAvoidcomplexity of consumable identification process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The manual mechanical process of identifying and matching consumables with appropriate parameters is replaced by an automated electronic system. The torch system uses a data reading device (e.g., RFID reader) to electronically read identification data from the consumable's data storage device, automatically determining compatibility and configuring parameters without requiring operator expertise in manual identification.

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

Solution Approach 2:

A data storage device (e.g., RFID tag) acts as an intermediary between the consumable component and the torch control system. This intermediary carries identification information and parameters, enabling automatic verification of consumable compatibility and transmission of operating parameters without requiring direct human intervention in the matching process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Extent of automation

If data storage devices are integrated into consumables, then automatic parameter transfer is enabled, but manufacturing complexity increases

Engineering Contradiction:
Improveautomation of parameter configurationVSAvoidease of consumable manufacturing
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The data storage device (e.g., RFID tag) is a universal component that can be integrated into various types of consumable components (electrodes, nozzles, shields) without requiring custom manufacturing processes for each consumable type. This multi-functional approach allows the same data storage technology to serve multiple purposes across different consumables, simplifying the overall manufacturing process despite the added automation capability.

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