Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single laser processing machine is used for both 2D and 3D processing, then installation space and setup time are reduced, but the operation becomes complicated and difficult due to the need to switch between different tables and workpiece positions
Solution Approach 1:
The laser processing machine is segmented into two independent processing units: a first laser processing unit dedicated to 3D processing with a pivot table, and a second laser processing unit dedicated to 2D processing with a work table. This segmentation allows each unit to be optimized for its specific function while both can operate within the same machine structure, enabling versatile processing without complicating the operational switching between modes
Solution Approach 2:
The laser processing machine is designed with universal functionality to perform both 2D and 3D processing through its dual-unit configuration. The control unit manages both processing types, and the shared laser beam source and control system provide multi-functionality, allowing a single machine to handle diverse processing requirements without requiring separate dedicated machines
2Ease of manufacture
If separate tables are provided for 2D and 3D processing, then each table can be optimized for its specific function, but the device complexity increases
Solution Approach 1:
The first laser processing unit and second laser processing unit are merged into a single integrated laser processing machine. They share common components including the laser beam source, control unit, and overall machine structure. This merging reduces device complexity by eliminating redundant systems while maintaining the functional optimization of separate processing units for 2D and 3D operations
3Area of stationary object
If the work table is installed above the pivot table unit, then space is utilized efficiently, but the wheels must be designed to roll on rail units while maintaining contact only when installed
Solution Approach 1:
The work table's connection to the rail units is designed to be dynamic rather than permanently fixed. The wheels naturally contact and engage with the rail units when the work table is in its installed position above the pivot table, providing stable support. When the work table is removed, the wheels disengage automatically. This dynamic interaction simplifies installation and removal operations while maintaining space efficiency

AI summary
A laser processing system (ST) includes a first laser processing unit (LU1) and a second laser processing unit (LU2). The first laser processing unit is provided with a pivot table unit (93) having a pivot table (931) that holds a first workpiece to be processed by a laser beam and a drive unit (932) that drives the pivot table. The second laser processing unit is provided with a pair of rail units (94, 95) laid parallel with the pivot table unit interposed therebetween and a work table (3). The work table has a workpiece support unit (32G, 32BG) that supports a second workpiece to be processed by a laser beam, a table base (31) that supports the workpiece support unit, posts (312a-d) that support the table base, and wheels (313, 314) that roll on the pair of rail units. The work table is configured so that only the wheels are in contact with the pair of rail units when the table base is installed above the pivot table unit.
