Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If operator expertise is used to determine output direction, then output quality can be improved through experience, but time consumption and cost increase continuously
Solution Approach 1:
The patent creates a virtual copy of the 3D model and performs thermal simulations on this digital replica to predict heat dissipation characteristics. This allows determining the optimal output direction through simulation rather than relying on operator experience and trial-and-error physical testing, thereby reducing time consumption while maintaining output quality.
Solution Approach 2:
The patent performs thermal simulation and heat dissipation analysis before the actual 3D printing process to pre-determine the optimal output direction. By conducting this analysis in advance, the system eliminates the need for operators to spend time experimenting with different directions during production, thus reducing time loss while ensuring high output quality.
2Reliability
If trial-and-error method is used to find appropriate output direction, then heat dissipation issues can be identified, but material waste and cost increase
Solution Approach 1:
The patent uses a digital twin approach by creating a virtual model to simulate thermal behavior. This allows identifying heat dissipation issues and optimizing output direction in the virtual environment before actual printing, preventing material waste that would occur during physical trial-and-error testing while ensuring reliable heat dissipation.
Solution Approach 2:
The patent performs thermal simulation and heat dissipation analysis before the actual 3D printing process to pre-determine the optimal output direction. By conducting this analysis in advance, the system identifies potential heat dissipation problems and material waste risks before production begins, thereby ensuring reliable heat dissipation while minimizing material loss.
3Ease of operation
If unexperienced operators determine output direction, then operational flexibility is maintained, but output stability deteriorates
Solution Approach 1:
The patent replaces operator judgment with an automated simulation system that creates a virtual model to analyze heat dissipation characteristics. This allows unexperienced operators to use the system's objective thermal analysis results to determine output direction, maintaining operational flexibility while ensuring stable and consistent output quality regardless of operator experience level.
Solution Approach 2:
The patent implements an automated system that performs thermal simulation and independently determines the optimal output direction without relying on operator expertise. The system serves itself by using algorithmic analysis of heat dissipation characteristics to provide stable, consistent recommendations, enabling operational flexibility while ensuring output stability even when operated by unexperienced personnel.
4Measurement precision
If multiple simulations are performed for different output directions, then heat dissipation accuracy is improved, but computational time increases
Solution Approach 1:
The patent divides the thermal simulation process into targeted segments by focusing simulations only on critical regions and key output direction candidates. This segmentation approach maintains high heat dissipation accuracy by analyzing essential thermal pathways while reducing the total computational time compared to performing exhaustive simulations on all possible directions.
