Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire guide devices for laser deposition welding lack effective collision protection, as they require replacement after a collision, leading to increased costs and downtime, and do not allow for adjustments in wire guide direction or orientation.
Innovation Solution
A wire guide device with multiple guide parts that are movably and releasably coupled, allowing for relative displacement or tilting in the event of a collision, enabling non-destructive collision protection and adjustable wire guide settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined breaking point is provided on the wire guide device for collision protection, then damage to other elements is prevented, but the wire guide device must be replaced after collision, generating costs and downtime
Solution Approach 1:
The wire guide device is divided into multiple guide parts that are movably coupled to each other. Each guide part can independently move or deflect relative to the others upon collision, allowing the collision energy to be distributed and absorbed by the relative movements rather than causing catastrophic failure requiring replacement.
Solution Approach 2:
The guide parts are designed with movable couplings that allow dynamic adjustment and movement in response to collision forces. This dynamic capability enables the structure to adapt to collision events through controlled movement rather than rigid failure, maintaining functionality after collision events.
2Reliability
If a predetermined breaking point is provided on the wire guide device, then damage to other elements is prevented, but replacement costs and time are incurred
Solution Approach 1:
By segmenting the wire guide device into multiple movably coupled guide parts, the invention eliminates the need for a predetermined breaking point that would require replacement. The movable couplings allow the structure to absorb collision energy through controlled movement and deformation, maintaining functionality without requiring costly replacement of entire components.
Solution Approach 2:
The invention changes the structural parameters of the wire guide device from a rigid, fixed structure to a flexible, movably coupled structure. This parameter change allows the device to respond to collision forces through movement and controlled deformation, eliminating the need for replacement and reducing operational costs.
3Device complexity
If conventional wire guide devices are formed as rigid components with fixed connections, then structural simplicity is maintained, but no adjustment of wire guide direction or orientation is possible
Solution Approach 1:
The wire guide device is segmented into multiple guide parts with movable couplings between them. This segmentation enables each part to be adjusted independently relative to the others, providing flexibility in wire guide direction and orientation while maintaining a relatively simple overall structure based on modular components.
Solution Approach 2:
The movable couplings between guide parts introduce dynamic adjustability to the structure. Each guide part can be positioned and oriented independently, allowing the wire guide direction to be adjusted to accommodate different welding configurations while maintaining structural simplicity through the use of standardized movable connection mechanisms.

AI summary
A wire guide device for a laser processing head for deposition welding by a laser beam has a plurality of guide parts arranged in succession to guide a welding wire. Two of the guide parts are movably coupled to each other by a coupling element. A second guide part of the two guide parts is displaceable and/or tiltable relative to a first guide part of the two guide parts.
