Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding helmets are bulky, heavy, and difficult to store, and they hinder the visibility of surrounding objects due to their large size and low light transmission, requiring separate eye shields and helmets, which are cumbersome and costly to manage.
Innovation Solution
Automatic shading goggles in a goggle shape with a compact design, adjustable shading, and air vents to prevent condensation, featuring a soft silicon skirt for improved fit and bonding, a light detecting sensor, and a control panel for varying light transmission between welding and security modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional welding helmet is used to block strong light during welding operation, then the worker's eyes are protected from harmful light, but the helmet becomes bulky and heavy, laying heavy strain on the worker's neck and making storage difficult
Solution Approach 1:
The invention divides the welding protective device into separate functional components: a compact goggle body with LCD lens for light filtering, a removable skirt for additional protection, and a lightweight headband. This segmentation allows the core protective function to be maintained while eliminating the bulk and weight of conventional full-face helmets.
Solution Approach 2:
The goggle is designed to perform multiple functions: blocking harmful welding light through the LCD lens, providing additional protection with the removable skirt, and maintaining a compact portable form. This multi-functionality allows a single lightweight device to replace both welding helmet and safety goggles.
2Object-affected harmful factors
If the light transmission of LCD cartridge is remarkably lowered to block strong light during welding operation, then the strong light is blocked, but it becomes difficult to distinguish surrounding objects
Solution Approach 1:
The LCD lens dynamically adjusts its light transmission properties based on the welding operation state. During welding, it blocks harmful light while maintaining sufficient visibility. The lens can be tilted or removed to change its optical properties, providing full visibility when welding is not performed.
Solution Approach 2:
The goggle design prepares for different operational states in advance: the LCD lens is positioned to block light during welding, but can be easily tilted upward or removed beforehand when welding stops, ensuring immediate full visibility for observing surrounding objects without delay.
3Object-affected harmful factors
If a conventional welding helmet is used to protect eyes during welding operation, then eye protection is provided, but the large size requires separate eye shield and helmet, which are cumbersome to attach and detach and costly to purchase and maintain
Solution Approach 1:
The invention merges the welding helmet and safety goggles into a single integrated device. The goggle body with LCD lens provides welding light protection, while the removable skirt provides additional protection from broken pieces. This combination eliminates the need for separate helmets and eye shields, reducing both component count and management complexity.
Solution Approach 2:
The single goggle device provides universal protection for both welding operations and general safety requirements. The removable skirt can be attached when additional protection is needed and removed when not required, providing versatile protection in one device that replaces multiple separate protective equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the weight burden on workers, allows easy distinction of surrounding objects, and combines welding and other operations efficiently by adjusting light transmission based on the task, while preventing eye damage from harmful light.
Implementation Method 1
a light detecting sensor (70) formed at one side of the inside body (10), detecting a light over a pre-set value and generating a driving signal when the light over the pre-set value is generated from an outside
Implementation Method 2
the light transmission of the LCD cartridge 130 becomes lower according to the generated driving signal to block the strong light
Implementation Method 3
air vents are formed at one side of the front body, so that the air is circulated to the inside and outside of the skirt part, thereby it can previously prevent the condensation from being occurred on the LCD lens owing to the heat generated from an eyeball of the worker

AI summary
Provided is automatic shading goggles in that a welding helmet is manufactured in a goggle shape, so that the size thereof is compact and the weight thereof is light and a shading degree of a LCD lens can be selectively adjusted in any one mode of a welding mode for shielding a harmful light generated during welding operation and a security mode for shielding a visible ray, so that it can reduce a burden of the weight applied to a worker, block a strong light during welding operation, and easily distinguish the surrounding objects, when the welding operation is not performed.
