Integrated ADF Magnification Lens for Adjustable Welding Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding magnifiers in welding helmets are cumbersome to switch, prone to scratching, and can cause double vision due to stacking multiple lenses, complicating adjustments based on varying welding conditions and user's sight limitations.
Innovation Solution
An automatic darkening filter (ADF) housing integrates a mechanically adjustable magnifying lens, allowing continuous adjustment of magnification from 1.00 to 3.00 without swapping lenses, with user-controlled adjustments for angle, position, or focal length of optical lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate lenses are stacked to provide magnification, then magnification capability is achieved, but device complexity and ease of operation deteriorate due to the need to swap and stack multiple lenses
Solution Approach 1:
The patent combines the ADF lens and magnifying lens into a single integrated housing structure. The magnifying lens is positioned directly behind the ADF lens within the same housing, eliminating the need for separate lens components and simplifying the overall device architecture while maintaining both darkening and magnification functions.
Solution Approach 2:
The integrated housing serves multiple functions simultaneously: it provides auto-darkening protection through the ADF lens, magnification through the integrated magnifying lens, and allows for adjustable magnification levels. This multi-functional design replaces the need for multiple separate lenses with a single versatile component.
2Adaptability or versatility
If multiple lenses are stacked for magnification, then magnification is achieved, but ease of operation worsens due to cumbersome lens swapping
Solution Approach 1:
The patent implements a mechanically adjustable magnifying lens within the integrated housing that allows continuous adjustment of magnification strength from 1.00 to 3.00. This dynamic adjustment mechanism eliminates the need to swap lenses, enabling users to change magnification levels on-the-fly during welding operations.
Solution Approach 2:
The magnification strength is made variable through mechanical adjustment of the magnifying lens parameters (position, angle, or focal length). This allows the lens system to adapt to different welding conditions and user preferences without requiring physical replacement of lens components.
3Adaptability or versatility
If multiple lenses are stacked for magnification, then magnification capability is provided, but reliability worsens due to lens scratching and double vision
Solution Approach 1:
By integrating the magnifying lens and ADF lens into a single housing, the patent reduces the total number of lens interfaces and stacking layers. This minimizes the risk of double vision issues and reduces the surface area exposed to potential scratching, thereby improving reliability and visual clarity.
4Adaptability or versatility
If separate magnifying lenses are used, then adaptability to different welding conditions is achieved, but device complexity increases due to additional components
Solution Approach 1:
The integrated housing with adjustable magnifying lens serves as a universal solution for various welding conditions. The single component can be adjusted to provide different magnification levels (1.00-3.00) to accommodate different welding tasks, eliminating the need for multiple specialized lenses while maintaining adaptability.
