Auto Darkening Welding Mask External Regulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto darkening masks require the weld cap to be removed each time the regulating system is used, making the operation cumbersome and labor-intensive.
Innovation Solution
An auto darkening mask design where the filter mechanism is separated into a lens module and a regulating system, with the lens module inside the weld cap and the regulating system outside, connected via a line, allowing direct use of the regulating system without removing the weld cap, featuring a control mechanism with knobs and switches for shade and sensitivity adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the regulating system is installed inside the weld cap, then the structure is compact and integrated, but the operation becomes troublesome requiring the weld cap to be removed for regulation
Solution Approach 1:
The filter mechanism is segmented into two independent parts: the lens module remains inside the weld cap while the regulating system is placed outside. They are connected through a connecting line that allows signal and power transmission. This segmentation enables the regulating system to be accessed and operated independently without removing the weld cap, resolving the contradiction between structural integration and operational convenience.
Solution Approach 2:
A connecting line acts as an intermediary between the lens module inside the weld cap and the regulating system outside. This connecting line transmits control signals and power, enabling the external regulating system to control the internal lens module without physical access to the interior of the weld cap, thus maintaining both structural integrity and operational accessibility.
2Ease of operation
If the regulating system is placed outside the weld cap, then the operation convenience is improved, but the structural integration is reduced
Solution Approach 1:
The system is divided into an internal lens module and an external regulating system, connected through a minimizing connecting line. This segmentation allows the bulky regulating components to be positioned outside for easy access while maintaining a compact overall structure through the use of a thin connecting line that minimizes spatial separation.
3Ease of operation
If the weld cap is removed for regulation, then the regulating system can be accessed, but the operation time is increased and efficiency reduced
Solution Approach 1:
The regulating system is extracted from the interior of the weld cap and positioned on the exterior surface. This extraction allows operators to access and adjust the regulating system directly without the need to remove the weld cap, significantly reducing operation time and improving welding efficiency while maintaining full regulatory functionality.

AI summary
An auto darkening mask which has a weld cap and a filter mechanism, wherein the filter mechanism includes a lens module, a connecting line and a regulating system; and the weld cap is provided with a visible window. The lens module is assembled inside the weld cap and is opposite to the visible window of the weld cap. The regulating system protrudes out of an outer side of the weld cap and is connected with the weld cap, and the lens module is connected with and controlled by the regulating system through the connecting line.
