Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additive manufacturing layering process is used to build 3D parts, then manufacturing flexibility and customization are improved, but surface property control and finish quality deteriorate
Solution Approach 1:
The patent applies preliminary action by determining the required flash radiation parameters (intensity, duration, wavelength) before the actual radiation application. The system calculates and stores the optimal flash parameters in advance based on the desired surface property changes, ensuring precise control when the radiation is actually applied to the built part.
Solution Approach 2:
The patent employs parameter changes by systematically varying flash radiation parameters (intensity, duration, wavelength) to achieve different surface property outcomes. The system adjusts these parameters based on the built part characteristics and desired surface properties, enabling precise control over surface roughness, texture, and other surface characteristics after additive manufacturing.
2Manufacturing precision
If flash radiation is applied to modify surface properties, then surface property precision is improved, but process complexity increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically determine and execute the optimal flash radiation parameters without requiring manual intervention. The processor automatically calculates the required flash parameters based on the desired surface property changes and controls the radiation source accordingly, reducing operational complexity while maintaining high precision.
Solution Approach 2:
The patent applies feedback by using detected surface property levels to adjust and optimize the flash radiation parameters. The system measures the actual surface properties after radiation application and uses this information to refine subsequent radiation parameters, ensuring precise achievement of target surface properties while streamlining the process.
3Manufacturing precision
If multiple flash radiation applications are used to achieve desired surface properties, then surface property accuracy is improved, but manufacturing time increases
Solution Approach 1:
The patent applies preliminary action by determining the optimal number of flash radiation applications and their parameters in advance. The system calculates the required flash sequence (single or multiple applications) based on the desired surface property accuracy, allowing precise surface modification while minimizing the total number of applications needed.
Solution Approach 2:
The patent employs partial or excessive action by applying flash radiation with parameters that may slightly exceed the minimum required for surface modification. This approach achieves the desired surface property accuracy in fewer applications by using optimized intensity and duration parameters, thereby reducing total manufacturing time while maintaining precision.

AI summary
According to examples, an apparatus includes a processor and a memory on which is stored machine readable instructions. The instructions may cause the processor to identify an intended surface property level for a surface of a three-dimensional (3D) object, determine an amount of radiation to be applied as a flash of radiation onto the surface to obtain the intended surface property level, and output the determined amount of radiation to be applied as a flash of radiation, in which a radiation source is to flash apply the determined amount of radiation onto the surface of the 3D object.
