Solution Overview

Problem

Current welding helmet systems lack effective monitoring capabilities, which can impact the quality of welds in various materials and applications, as they do not provide real-time feedback or enhanced visualization during welding operations.

Innovation Solution

A welding helmet system with removable and upgradeable augmented and mediated reality eyeglasses that receive data from sensors, display welding metrics, and communicate with external systems, offering enhanced visualizations and audio feedback to improve welding operations and training by operating across the reality-virtuality continuum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional welding helmet systems are used, then the basic protective function is provided, but real-time monitoring and feedback capabilities are lacking

Engineering Contradiction:
Improvewelding monitoring capabilityVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the welding helmet protective shell with an integrated display system that merges multiple functions (protection, monitoring, visualization) into a unified device. The display system is coupled to the protective shell, creating an integrated assembly that provides both safety and real-time welding metrics visualization without requiring separate monitoring equipment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The welding helmet system is designed to perform multiple functions simultaneously: it provides physical protection during welding operations while also serving as a monitoring station that displays welding metrics, sensor data, and visual feedback. This multi-functional design eliminates the need for separate protective gear and monitoring devices.

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

2Manufacturing precision

If welding operations are performed without enhanced visualization, then the process is simple, but weld quality monitoring is insufficient

Engineering Contradiction:
Improveweld qualityVSAvoidoperator complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system incorporates sensor arrays that continuously monitor welding parameters and provide real-time visual feedback through the display system. The feedback loop allows operators to immediately see the effects of their welding techniques and adjust accordingly, improving weld quality through continuous monitoring and adjustment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The display system utilizes visual indicators including color changes to communicate welding status, quality metrics, and sensor data to operators. Different colors represent different welding conditions and quality levels, providing intuitive visual feedback that simplifies quality assessment.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If fixed welding helmet systems are used, then the structure is stable, but adaptability to different welding applications is limited

Engineering Contradiction:
Improveapplication flexibilityVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display system is designed with removable and reconfigurable components that can be dynamically adjusted or removed based on specific welding applications. The system transitions from a fixed configuration to a dynamic, adaptable configuration that can be customized for different welding tasks, materials, and environments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The welding helmet system is divided into separable modules including the protective shell, display system, and sensor arrays. This segmentation allows individual components to be removed, replaced, or reconfigured based on specific welding applications, providing versatility without requiring complete system redesign.

Inventive Principle:
Principle #1Segmentation
