Solution Overview

Problem

Advanced welding equipment has become complex and costly, making it difficult to interface and program, particularly due to the need for sophisticated electronics and user input controls, which increases operational complexity and training requirements.

Innovation Solution

A welding or cutting system that utilizes a mobile communication device with camera, display, and motion sensor to input and communicate operational parameters to a power supply, eliminating the need for user input controls on the power supply and allowing remote operation, thereby simplifying the user interface and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If welding power supply includes user input interface and control circuitry, then operational control capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improveoperational control capabilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the user input interface and control circuitry from the welding power supply itself, relocating these functions to a separate mobile communication device. The power supply retains only the essential welding functionality and communication interface, while the mobile device handles parameter input, display, and complex control operations through its existing screen, keyboard, and processing capabilities.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent leverages the universal capabilities of mobile communication devices (smartphones, tablets, laptops) which already possess screens, keyboards, processors, and communication interfaces. By utilizing these existing multi-functional components for welding control, the system avoids duplicating these functions in the power supply, thereby reducing overall device complexity while maintaining full operational control capability.

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

2Ease of operation

If welding power supply includes user input interface and control circuitry, then operational control capability is improved, but cost increases

Engineering Contradiction:
Improveoperational control capabilityVSAvoidcost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent extracts the expensive user input interface and control circuitry components from the welding power supply manufacturing process. By relocating these functions to a separate mobile device that users already possess, the power supply can be manufactured with simpler, less expensive components, directly reducing production costs while maintaining full operational control capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent utilizes the mobile communication device's existing built-in components (screen, keyboard, processor, communication interfaces) that users already own for welding control operations. This self-service approach eliminates the need for the power supply manufacturer to provide these expensive components, thereby reducing manufacturing costs while maintaining full operational functionality.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If welding power supply includes user input interface, then programming capability is improved, but operational complexity increases

Engineering Contradiction:
Improveprogramming capabilityVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the programming and parameter input functions from the power supply to the mobile communication device. The mobile device's existing keyboard, screen, and processing capabilities handle all programming operations, parameter entry, and configuration tasks, while the power supply simply executes received commands. This separation reduces operational complexity at the power supply interface while maintaining full programming capability.

Inventive Principle:
Principle #2Taking out (Extraction)
