Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal laminating and modeling methods face challenges in forming large modeled objects without significantly increasing the size of the apparatus, particularly due to the need for a large gate-shaped frame.
Innovation Solution
A metal laminating and modeling method that utilizes a rotatable and tiltable table with a movable welding torch, allowing for the formation of weld beads on a horizontal surface and at varying angles to create large modeled objects without enlarging the apparatus footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a gate-shaped frame with welding torch is used for metal laminating and modeling, then weld beads can be formed by arc discharge, but the apparatus size becomes large when forming large modeled objects
Solution Approach 1:
The patent divides the gate-shaped frame into a movable section and a fixed section. The movable section can be moved along the fixed section, allowing the welding torch to reach different positions without requiring the entire frame to be large. This segmentation enables compact apparatus design while maintaining the capability to form weld beads for large modeled objects.
Solution Approach 2:
The patent introduces movability to the gate-shaped frame structure. By making part of the frame movable rather than fixed, the apparatus can adapt its configuration to accommodate large modeled objects without permanently requiring a large apparatus size. The movable section adjusts its position dynamically during the welding process.
2Manufacturing precision
If the table is inclined at a larger angle for modeling, then the flow of molten metal can be controlled, but the welding torch configuration becomes more complex
Solution Approach 1:
The patent combines the table inclination function with the torch inclination function into a coordinated system. Both the table and the welding torch are inclined at corresponding angles, and their inclination mechanisms are linked or synchronized. This merging approach allows the system to handle molten metal flow control efficiently without requiring entirely separate complex adjustment mechanisms for each component.
