Wire Feeder Locking Mechanism for Inclined Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional open wire feeders for welding are limited to level surfaces due to stability issues and pose safety hazards from high voltage and rotating components, and they are not suitable for inclined positions or overhead use.
Innovation Solution
A wire feeder design featuring a frame with first and second supports for a wire reel hub, allowing rotation and locking to prevent displacement, and a cover that can be opened for access while maintaining protection from dust and dirt, enabling safe and stable operation on inclined surfaces and overhead boom attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional open wire feeder is used, then the wire reel can rotate freely, but the wire feeder cannot be set on an inclined surface without the wire reel falling down
Solution Approach 1:
The patent changes the operational parameters by introducing a locking mechanism that can secure the wire reel hub at specific positions. The locking means includes a locking member that engages with the wire reel hub to prevent it from sliding down on inclined surfaces, while still allowing free rotation during normal operation. This enables the wire feeder to adapt to inclined surfaces without compromising wire reel stability.
2Stability of the object's composition
If the wire reel hub is locked to prevent displacement, then stability is improved, but rotation of the wire reel hub is restricted
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than static. The locking member can be engaged or disengaged as needed, allowing the system to switch between locked (stable) and unlocked (rotating) states. During welding operation, the locking member is disengaged to allow free rotation of the wire reel hub, while during transport or when not in use, it can be engaged to prevent displacement.
3Ease of operation
If an open wire feeder design is used, then access to the wire reel is easy, but the user is exposed to safety hazards from high voltage and rotating parts
Solution Approach 1:
The patent employs a cover that can be opened or closed to enclose the wire reel and wire reel hub. When closed, the cover protects users from high voltage exposure and rotating parts. When opening is required for wire reel replacement, the cover can be easily opened providing access. This flexible enclosure solution simultaneously addresses safety protection and ease of operation.
4Object-affected harmful factors
If a cover is added to protect from high voltage and rotating parts, then safety is improved, but the structure becomes more complex
Solution Approach 1:
The cover is designed to serve multiple functions: it protects users from high voltage exposure, shields from rotating parts, and can also protect against dust and dirt. By combining multiple protective functions into a single component, the overall structural complexity is minimized while achieving comprehensive safety and protection.
