Welding Shield Platform Base Adjusting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current welding shields lack an effective adjusting device for calibrating and presetting the height or depth of welding tool tips, leading to inaccurate adjustments and reduced protection for welders due to limited visibility and cumbersome design.
Innovation Solution
A protective welding shield with a platform base and fastening device that allows for adjustable securing of the welding tool, featuring a sub-floor slot for precise positioning of the welding tip, and an internal illumination lamp for improved visibility during setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a welding shield is used to protect the welder's eyes, face and hands from sparks, heat and weld splatter, then protection from sparks and heat is improved, but visibility of the welding tool and weld area in ambient light deteriorates
Solution Approach 1:
The welding shield is divided into multiple functional zones: a transparent upper portion for ambient light visibility, a darkened lower portion for arc welding protection, and an adjustable positioning mechanism. This segmentation allows different parts of the shield to serve different protective functions simultaneously, maintaining visibility above while providing protection below.
Solution Approach 2:
The welding shield incorporates an adjustable positioning mechanism that allows the shield to be dynamically repositioned relative to the welding tool. This enables the welder to adjust the shield's location to optimize both protection and visibility based on the specific welding task and lighting conditions.
2Object-affected harmful factors
If the welding shield is designed to house the welding tip within the shield body, then protection from sparks and heat is improved, but accuracy in positioning the welding tip relative to the shield deteriorates
Solution Approach 1:
The system includes a preliminary positioning mechanism with alignment features that pre-establish the correct spatial relationship between the welding tip and the shield before welding begins. This preliminary action ensures accurate tip positioning without requiring complex real-time adjustments during welding.
Solution Approach 2:
The invention replaces manual guesswork and freehand positioning with a structured mechanical alignment system featuring guide rails, positioning pins, and adjustable clamps. This mechanical substitution provides repeatable, precise positioning of the welding tip relative to the shield.
3Object-affected harmful factors
If the welding shield is designed as a standalone protective device, then protection function is improved, but ease of operation deteriorates as the welder must use two hands
Solution Approach 1:
The welding shield is merged with the welding tool into an integrated assembly where the shield is mechanically coupled to the tool handle or body. This combination allows the welder to operate the welding tool with one hand while the shield provides automatic protection, eliminating the need to separately hold the shield.
Solution Approach 2:
The integrated shield-tool assembly serves multiple functions simultaneously: the shield provides protective coverage, the tool performs welding, and the combined unit offers ergonomic handling. This multi-functionality allows a single device to replace what would otherwise require separate components operated with multiple hands.
4Ease of manufacture
If the welding shield is designed with fixed structure and limited protection features, then manufacturing cost is reduced, but adaptability to different welding applications deteriorates
Solution Approach 1:
The welding shield incorporates adjustable and interchangeable components such as repositionable shield sections, removable filter lenses, and adaptable mounting mechanisms. These dynamic features allow the same basic shield structure to be configured for different welding applications, materials, and positions without requiring completely different shield designs.
Solution Approach 2:
The shield design includes universal mounting interfaces and standardized attachment points that allow it to be adapted to various welding tool types and configurations. This universality enables a single shield design to serve multiple welding applications while maintaining cost-effective manufacturing through standardized components.

AI summary
A welding shield with a welding tool in combination with an adjusting device for adjusting position of a welding tool tip. The welding shield comprises a welding shield body having an outer wall, a weld viewer, and a fastening device for securing the welding tool. The adjusting device includes a platform base comprising a floor member, a wall member surrounding the floor member and a sub-floor slot formed in the floor member. The sub-floor slot has a sub-floor surface spaced inwardly from a floor surface of the floor member. The outer wall of the protective welding shield is configured to be mounted to the floor member of the platform base so that a bottom edge of the welding shield body is disposed within the wall member of the platform base and the welding tip of the welding tool faces the sub-floor slot.
