Welded Frame Member Alignment Using Movable Positioning Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning frame members in welded assemblies lack precision and control, often resulting in improper alignment and imbalances due to the inability to angularly position tubular frame members relative to support members effectively.
Innovation Solution
A system comprising a support member with a projection of convex or concave geometry and a movable positioning member that allows frame members to be angularly displaced before welding, enabling precise positioning and alignment through engagement of corresponding geometries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If tubular frame members are rigidly welded to support members without angular positioning capability, then welding process is simple and fast, but alignment precision and structural balance deteriorate
Solution Approach 1:
The positioning member enables preliminary angular adjustment of the tubular frame member relative to the support member before welding occurs. This preliminary positioning action allows the frame member to be accurately aligned at the desired angle, and then fixed in place through welding, thereby achieving precise alignment without requiring complex positioning systems during the welding process itself
Solution Approach 2:
The positioning member acts as an intermediary device between the tubular frame member and the support member. It provides a mechanism for angular adjustment and temporary holding of the frame member at the correct orientation, mediating the connection process to achieve precise alignment while maintaining relative simplicity of the overall system
2Manufacturing precision
If tubular frame members are welded without angular repositioning capability, then manufacturing process is simple, but alignment accuracy and structural integrity worsen
Solution Approach 1:
The system performs preliminary angular positioning of the tubular frame member using the positioning member before the welding operation. This allows the frame member to be accurately aligned at the correct angle relative to the support member, ensuring high alignment accuracy while keeping the manufacturing process straightforward through the simple mechanism of moving and securing the positioning member
3Manufacturing precision
If angular positioning of frame members is not permitted, then welding operation is fast and efficient, but alignment quality and structural balance deteriorate
Solution Approach 1:
The positioning member enables quick preliminary angular adjustment of the tubular frame member before welding. By performing the positioning action in advance and securing it in the correct orientation, the system achieves high alignment quality without significantly impacting welding speed, as the positioning step is simple and rapid
Solution Approach 2:
The positioning member provides dynamic adjustability during the assembly process, allowing the tubular frame member to be positioned at different angles relative to the support member. This dynamic positioning capability enables precise alignment while maintaining efficient workflow, as the positioning member can be easily moved and secured

AI summary
A system for improving alignment in welded assemblies is provided. The system includes a support member having a surface and a projection extending from the surface. The projection may include one of a convex or a concave geometry. The system includes a positioning member provided over the support member for receiving a frame member. The positioning member may be movable over the support member, and the positioning member may include a geometry configured to engage the one of the convex or the concave geometry. The frame member may be movable from a first position relative to a center of the projection to a second position relative to the center of the projection during movement of the positioning member over the support member.
