Solution Overview
Problem
Existing equipment is inadequate for handling and feeding small quantities of wire during welding, leading to wire bending, recoiling, and disruptions in the welding process, resulting in costly equipment shutdowns and unusable wire.
Innovation Solution
A backpack-style wire handling facilitator with a spool, alignment wheel, brake pedal, drive rollers, and motorized drive wheels to control and feed wire smoothly into a welding gun, preventing bending and recoiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If very short segments of wire are used, then the wire can be hand bent to eliminate cast and provide straight wire, but the wire quantity is insufficient and requires frequent replacement
Solution Approach 1:
The wire handling system is divided into discrete components: a spool for wire storage, a guide wheel for alignment, drive rollers for feeding, and a brake mechanism for control. This segmentation allows each component to perform its specific function optimally while working together to handle longer wire segments effectively.
Solution Approach 2:
The guide wheel acts as an intermediary between the spool and the welding gun, receiving wire from the spool and directing it into the gun. This intermediary component ensures proper wire alignment and prevents casting issues without requiring short wire segments.
2Quantity of substance
If longer segments of wire are used, then wire quantity is sufficient for continuous welding, but the wire tends to re-coil or bend out of linearity causing equipment disruptions
Solution Approach 1:
The wire is pre-aligned in the guide wheel groove before entering the welding gun. The brake mechanism is pre-positioned to engage with the spool, ready to control wire feed. These preliminary actions prevent wire casting and bending before they can occur during the welding process.
Solution Approach 2:
The brake mechanism provides continuous feedback control on wire feed from the spool, adjusting tension to prevent over-winding and re-coiling. The drive rollers also provide controlled feedback to maintain consistent wire tension and alignment throughout the welding process.
3Manufacturing precision
If wire is not controlled during feeding, then the wire bends in any direction and does not lay into the channel to form the bead, but adding control mechanisms increases device complexity
Solution Approach 1:
The guide wheel has a groove with specific local geometry designed to match the wire diameter and maintain proper alignment. This localized structural feature provides precise wire control at the critical point where wire enters the welding gun, without requiring complex control mechanisms throughout the entire system.
4Loss of substance
If wire snarls and bends, then the wire becomes useless for re-use and is costly to replace, but preventing this requires additional control mechanisms
Solution Approach 1:
The drive rollers and brake mechanism work continuously to maintain wire tension and alignment from the spool through the guide wheel to the welding gun. This continuous control action prevents wire snarling and bending throughout the entire wire feed process, maximizing wire utilization and minimizing waste.
