Welding Wire Coil Container with Segmented Metal Cage and Cardboard Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding wires with diameters of 2.00 mm or more face difficulties in being fed through wire guiding systems due to mechanical constraints, and existing solutions like wire pushing systems have been ineffective.
Innovation Solution
A container comprising a metal cage with an octagonal cross section and a cardboard wall, where the metal cage provides mechanical stability and the cardboard wall protects against contamination, allowing for efficient handling and transportation of large-diameter welding wires, with a reduced-diameter starting portion facilitating insertion into welding equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding wire with diameter of 2.00 mm or more is used for submerged arc welding, then welding performance is improved, but the wire cannot be fed through the wire guiding system
Solution Approach 1:
The container is divided into a metal cage structure and a cardboard wall structure, with each component serving specific functions. The metal cage provides mechanical strength while the cardboard wall provides protection, allowing the system to handle large-diameter wire effectively
Solution Approach 2:
A dome is provided at the end of the side portion to guide the welding wire when withdrawn from the container. This intermediary component facilitates the transition of thick wire from the container to the welding equipment, solving the feeding problem
2Ease of operation
If wire pushing systems are used to feed large-diameter wire, then wire feeding is attempted, but the solution is not convincing
Solution Approach 1:
The invention extracts the wire feeding problem from the container design by providing a specialized dome structure at the container end that guides wire withdrawal. This separate guiding mechanism works independently of pushing systems, achieving reliable feeding without complex mechanical pushers
3Strength
If a strong container structure is used to hold large-diameter wire, then mechanical strength is improved, but manufacturing complexity increases
Solution Approach 1:
Different parts of the container have different properties optimized for their specific functions: the metal cage provides mechanical strength and structural support, while the cardboard wall provides protection against contamination. This local differentiation achieves overall strength without requiring the entire structure to be complex metal construction
Solution Approach 2:
The container uses a composite structure combining metal cage and cardboard wall, leveraging the advantages of both materials. The metal provides strength while the cardboard provides protective qualities, achieving high strength-to-complexity ratio
