Solution Overview

Problem

Conventional weld training systems are expensive, limiting the availability and usage time for welding operators, as they often rely on virtual or augmented reality methods that are costly to acquire and operate, resulting in insufficient hands-on training opportunities.

Innovation Solution

A low-cost weld training device that simulates the look, feel, and sound of a real welding torch using a vibration module, proximity sensors, and audio feedback, allowing for hands-on training and communication with external devices for feedback and programming, thereby providing a cost-effective alternative for simulating various welding processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If virtual or augmented reality training systems are used, then training immersion and interactivity are improved, but acquisition cost and operating cost increase significantly

Engineering Contradiction:
Improvetraining interactivityVSAvoidacquisition cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent creates a simplified copy of the welding torch experience through a training device that replicates the essential tactile and operational characteristics without requiring expensive virtual or augmented reality systems. The training torch reproduces the feel, weight, and basic operational feedback of real welding equipment at a fraction of the cost.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The training device uses inexpensive, replaceable components such as training torches and workpieces that can be easily replaced if damaged or worn. This approach prioritizes low cost over durability, allowing institutions to acquire multiple units for simultaneous student use without significant investment.

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

2Reliability

If expensive training equipment is acquired, then training quality is improved, but availability and usage time per student decrease

Engineering Contradiction:
Improvetraining qualityVSAvoidtraining availability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The training system is divided into multiple independent, low-cost units that can be distributed across an institution. This segmentation allows multiple students to train simultaneously on separate devices rather than queuing for a single expensive system, thereby increasing overall training availability while maintaining consistent quality across all units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By using inexpensive training torches and consumable workpieces, the system enables high turnover and simultaneous use by multiple students. The low acquisition cost allows institutions to purchase numerous units, ensuring that training availability is not limited by equipment scarcity.

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

3Ease of operation

If real welding equipment is used for training, then hands-on experience is improved, but safety risks and equipment damage potential increase

Engineering Contradiction:
Improvehands-on experienceVSAvoidsafety risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The training device serves as an intermediary between the student and actual welding equipment. It provides authentic tactile feedback, weight, and operational mechanics without producing real heat, light, or hazardous fumes. This mediator allows students to develop muscle memory and operational confidence before transitioning to real welding equipment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The training torch creates a safe copy of the real welding experience by replicating the ergonomic characteristics, trigger operation, and tactile feedback without the dangerous byproducts of actual welding. Students gain hands-on experience with equipment that feels authentic but poses no safety risk.

Inventive Principle:
Principle #26Copying
