Innovation Solution
A laser-beam working machine comprising a first chuck with a rotatable grip, a laser head for irradiating the workpiece, and a second chuck with guide rollers that move along the main axis to adjust the opening size and guide the workpiece, allowing the grip to pass through and enabling precise movement and rotation of the workpiece for effective machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a laser beam is used to machine long workpieces, then machining speed and precision are improved, but workpiece deflection and positioning accuracy deteriorate
Solution Approach 1:
The patent introduces guide rollers as intermediary support elements between the workpiece and the machining system. These guide rollers provide continuous support along the workpiece length, preventing deflection without interfering with the laser machining process. The guide rollers act as mediators that stabilize the workpiece while allowing the laser beam to machine the workpiece accurately.
Solution Approach 2:
The patent divides the workpiece support function into multiple segments by using multiple guide rollers distributed along the workpiece length. Each guide roller segment provides localized support, and collectively they maintain the workpiece stability throughout the entire machining process. This segmented support system prevents deflection while allowing precise positioning.
2Adaptability or versatility
If the workpiece is rotated and repositioned during machining, then machining versatility and adaptability are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent employs dynamically adjustable guide rollers that can move radially toward and away from the main axis. This dynamic adjustment capability allows the guide rollers to adapt to different workpiece sizes and orientations without requiring complex fixed mechanisms. The guide rollers can be repositioned to maintain optimal contact with the workpiece during rotation and machining operations.
Solution Approach 2:
The guide rollers are designed to perform multiple functions: supporting the workpiece during machining, guiding the workpiece during rotation, and enabling position changes. This multi-functionality reduces the need for separate dedicated mechanisms for each operation, thereby simplifying the overall device complexity while maintaining high adaptability.
3Stability of the object's composition
If guide rollers are used to support the workpiece, then workpiece stability is improved, but the grip cannot pass through the guide rollers
Solution Approach 1:
The guide rollers are designed with radial adjustability, allowing them to move toward and away from the main axis. During grip passage, the guide rollers retract radially to create sufficient clearance for the grip to pass through. During machining operations, the guide rollers extend radially to provide stable support contact with the workpiece. This dynamic positioning resolves the contradiction between support stability and grip accessibility.
