Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed irradiation position is used for all layer numbers, then the device operation is simple, but the modeling accuracy deteriorates due to inability to optimize for different layer configurations
Solution Approach 1:
The irradiation position is made dynamically adjustable based on the number of layers. The control mechanism varies the irradiation position in the direction of relative movement between the stage and regulation member according to the detected layer number, allowing optimization for each layer configuration while maintaining operational simplicity through automated control.
Solution Approach 2:
The irradiation position parameter is changed according to the number of layers. The control mechanism detects the layer number and automatically adjusts the irradiation position to optimal values for different layer ranges, achieving high modeling accuracy without requiring manual intervention or complex device modifications.
2Manufacturing precision
If the irradiation position is optimized for each layer number, then the modeling accuracy is improved, but the control mechanism complexity increases
Solution Approach 1:
The control mechanism incorporates feedback from layer number detection to automatically adjust the irradiation position. The system detects the current layer number and uses this information to determine the optimal irradiation position, achieving high adherence accuracy through automated feedback control without increasing physical device complexity.
Solution Approach 2:
The system performs self-adjustment of the irradiation position based on the detected layer number. The control mechanism automatically selects and applies the appropriate irradiation position for the current layer configuration, eliminating the need for manual adjustment or complex external control systems.
3Productivity
If a single irradiation region is used for all layer ranges, then the device operation is simple, but the productivity and accuracy are compromised due to suboptimal irradiation for certain layer numbers
Solution Approach 1:
The irradiation region is dynamically switched based on the layer number range. The control mechanism automatically selects between first and second irradiation regions according to whether the layer number falls within a first or second range, optimizing productivity for different stages of modeling while maintaining simple device operation through automated region selection.

AI summary
In a modeling apparatus, a stage includes a modeling surface on which a modeled object is formed. A regulation member includes a surface including an adjacent region, the regulation member is arranged with respect to the stage to form a holding region for holding a material between the adjacent region and the stage. An irradiation unit selectively radiates an energy ray to a region of the material via the adjacent region. A first moving mechanism moves the stage and the regulation member relative to each other in a direction along the modeling surface. A second moving mechanism moves the stage and the regulation member relative to each other in a lamination direction of the material. A control mechanism variably controls, based on the number of laminated layers of the material, an irradiation position of the energy ray to the material in the direction along the modeling surface.
