Here’s PatSnap Eureka !
Summary
Problems
Existing laser machining apparatuses require complex control systems to synchronously manage multiple lasers and scanners for additive manufacturing, necessitating the preparation and individual analysis of multiple machining programs to ensure that laser beams irradiate the same location and scan the same path, which is inefficient and error-prone.
Innovation solutions
A control device that includes a laser control unit capable of analyzing machining programs, generating machining condition commands, and synchronously controlling multiple lasers and scanners, allowing for the easy synchronization of laser beams across multiple systems by referencing stored machining condition information and adjusting control timing to ensure simultaneous irradiation and scanning.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If multiple machining programs are prepared and analyzed individually for each laser system, then synchronous control of multiple lasers can be achieved, but the control complexity increases significantly
Why choose this principle:
The patent combines multiple laser control systems into a unified control architecture where a single machining program is shared across all laser systems. The control device integrates machining program analysis, machining condition management, and laser control functions into one coordinated system, eliminating the need for separate program analysis for each laser while maintaining synchronous control accuracy.
Principle concept:
If multiple machining programs are prepared and analyzed individually for each laser system, then synchronous control of multiple lasers can be achieved, but the control complexity increases significantly
Why choose this principle:
The control device is designed with universal functionality to manage multiple laser systems through a single machining program. The machining condition information storage and retrieval mechanism allows the same program to be adaptively applied across different laser systems with different machining conditions, reducing control complexity while maintaining reliability.
