Welding Helmet Control for Spot Weld Tracking and Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding helmets lack the ability to efficiently measure welding operation time, cumulative time, and spot welds per second/minute/hour, and do not allow for easy conversion between welding and grind modes during operations, making it cumbersome to manage and switch between different welding conditions.
Innovation Solution
A welding helmet control device equipped with a light sensor or welding sensor, a controller, memory, display, shutter driver, and dial-type switches for setting and converting welding modes, which measures welding intensity, time, and number of spot welds, and allows for easy switching between welding and grind modes without removing the helmet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a welding helmet includes a cartridge that detects intense light to automatically drive LCD lens and shutter to be dark, then eye protection against intense light is improved, but the ability to measure spot welds per sec/min/hour and actual welding time deteriorates
Solution Approach 1:
The patent divides the control system into separate functional modules: the cartridge with optical sensor for light detection and eye protection, and a separate controller with welding sensor for measuring welding parameters. This segmentation allows each module to specialize in its function without interfering with the other's performance.
Solution Approach 2:
The controller is designed to perform multiple functions: it manages the LCD lens and shutter for eye protection while simultaneously measuring welding operation time, cumulative time, and spot weld frequency. This multi-functionality resolves the contradiction by integrating both protection and measurement capabilities in one system.
2Adaptability or versatility
If welding conditions are manually set and stored, then welding condition management is improved, but the ease of converting between welding and grind modes deteriorates
Solution Approach 1:
The system dynamically switches between welding mode and grind mode based on real-time operational needs. The controller automatically adjusts settings and measurements according to the current mode, eliminating the need for manual reconfiguration and enabling seamless transitions between different operational states.
Solution Approach 2:
The controller automatically detects the operational mode and configures appropriate settings without requiring manual intervention. It self-adjusts measurement parameters and control settings based on whether the system is in welding or grind mode, making the mode conversion process transparent and effortless for the user.
3Productivity
If a welding helmet is designed as a band type with automatic light detection, then work efficiency is improved, but the capability to measure and track welding operations deteriorates
Solution Approach 1:
The patent merges the automatic light detection system with the welding measurement system into an integrated controller. The controller simultaneously processes optical sensor data for automatic shutter control and welding sensor data for operation tracking, enabling both productivity enhancement through automation and precise measurement of welding operations.
