Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration of processing heads and rail systems is used, then the device structure is simple, but it cannot adapt to differently dimensioned components resulting in overcapacity or undercapacity
Solution Approach 1:
The device is divided into modular components including processing heads, rail systems, and support structures that can be independently configured. This segmentation allows the system to be adapted to different component sizes by selectively activating or deactivating specific modules, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The rail systems are designed to be movable and reconfigurable rather than fixed, allowing the processing heads to dynamically adjust their positions and configurations. This dynamic capability enables the device to adapt to various component dimensions while maintaining a relatively simple base structure that can be flexibly arranged.
2Speed
If processing heads are positioned far from the powder bed for quick laser focal point movement, then the laser focal point can be moved quickly, but the illumination area is limited
Solution Approach 1:
Multiple processing heads are arranged in a spatial distribution that utilizes three-dimensional positioning. This allows the system to maintain fast focal point movement by keeping individual heads at optimal distances while collectively covering a larger illumination area through the coordinated arrangement of multiple heads at different positions.
Solution Approach 2:
Multiple processing heads are combined to work in parallel, each contributing to the overall illumination area. This merging of multiple light sources allows the system to achieve both quick focal point movement (by maintaining appropriate head-to-bed distance) and extensive coverage (by combining the areas covered by multiple heads).
