Welding Protector with Sensor Feedback for Exposure Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welders are exposed to hazardous fumes, gases, and radiation during welding, posing health risks such as metal fume fever, siderosis, pulmonary edema, emphysema, and chronic bronchitis, and existing protective measures lack effective feedback mechanisms to manage exposure duration.
Innovation Solution
A welding protector system that includes sensors to monitor wearing state, a processor to calculate exposure time, and a feedback system providing visual, tactile, or audible signals to indicate whether to continue or interrupt the welding operation, connected through a communication network for real-time health management.

1Object-affected harmful factors
If welders wear protective equipment during welding operations, then health protection is improved, but there is no mechanism to monitor or control exposure duration leading to potential overexposure
Solution Approach 1:
The patent implements a feedback mechanism where sensors detect the welder's wearing state of protective equipment, the processor calculates exposure time based on sensor data, and the feedback system provides real-time information to the welder about their exposure duration. This closed-loop system enables workers to monitor their cumulative exposure and take appropriate breaks, directly resolving the information loss problem while maintaining health protection.
2Reliability
If real-time monitoring and feedback systems are added to welding protectors, then health management is improved, but device complexity increases
Solution Approach 1:
The welding protector is designed as a multi-functional device that combines protective functions (filtering fumes and radiation) with monitoring functions (sensors detecting wearing state) and communication functions (feedback system providing exposure information). By integrating these diverse functions into a single universal device, the system achieves reliable health management while avoiding the complexity of multiple separate systems.
Solution Approach 2:
The system employs sensors that automatically detect whether the protector is being worn without requiring manual input from the welder. The processor autonomously calculates exposure time based on sensor data, and the feedback system automatically provides exposure information to the welder. This self-service approach reduces operational complexity while maintaining high reliability in health monitoring.
