Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in welding and medical procedures face difficulties in accurately assessing their surroundings due to protective equipment, which obstructs their view of critical information, especially for those with lower skill levels, necessitating improved visualization tools.
Innovation Solution
A welding information providing device equipped with a camera unit, sensor unit, and processor that generates and displays high-quality images of the welding environment and state information, including temperature, direction, and speed, through a combination of camera frames synthesized using HDR technology and thermal imaging, while shielding welding light to protect the operator's vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective equipment is worn to shield welding light, then operator safety is improved, but operator's view of welding information and surrounding environment deteriorates
Solution Approach 1:
The patent introduces a camera unit and display unit as intermediary devices. The camera captures welding images and surrounding environment, while the display unit presents this information to the operator within the protective helmet. This intermediary system bridges the gap between light shielding and information visibility, allowing operators to see welding information without removing protective equipment.
Solution Approach 2:
The patent creates a visual copy of the welding environment through the camera unit. Instead of directly viewing the welding area (which would require removing protective equipment), the operator views a copied image captured by the camera and displayed on the display unit. This copying approach preserves both safety and information accessibility.
2Manufacturing precision
If automatic welding helmet is used to improve welding precision, then welding accuracy is improved, but operator's ability to check surrounding environment deteriorates
Solution Approach 1:
The patent makes the protective helmet multi-functional by integrating not only light shielding but also image capture and display capabilities. The helmet serves as both protective equipment and an information display device, allowing operators to maintain welding precision while simultaneously monitoring the surrounding environment through the displayed welding images.
Solution Approach 2:
The display unit acts as an intermediary that provides surrounding environment information within the protective helmet. Operators can check welding conditions and surrounding areas through the displayed images without compromising the protective function or welding precision, thus maintaining ease of operation.
3Object-affected harmful factors
If protective equipment obstructs view of welding information, then operator protection is improved, but welding operation efficiency deteriorates
Solution Approach 1:
The camera unit and display unit form an intermediary system that delivers welding information directly to the operator's field of view. This eliminates the need to remove protective equipment to check welding parameters, thereby maintaining both operator protection and welding operation efficiency.
Solution Approach 2:
The system provides real-time visual feedback of welding information and surrounding environment on the display unit. Operators can immediately see welding status, parameters, and environmental conditions without interruption to the welding process, maintaining high productivity while ensuring protection.

AI summary
This application relates to a welding information providing device. The device can provide a high-quality image that can easily identify a welding surrounding environment in addition to a portion adjacent to welding light by synthesizing images obtained under various photographing conditions. The device can also improve welding quality by providing an efficient guiding to an operator with respect to a current welding operation state. The device can include a cartridge unit that is located on a main body and selectively shields welding light, at least one camera unit that faces outward and obtains a welding image frame of a welding operation, and a sensor unit that detects a degree of light in at least a welding operation area. The device can also include an image display and a processor that provides a welding image generated through the welding image frame to the image display unit.
