Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If virtual molding simulation is used to generate provisional molding conditions, then setup time is reduced, but the conditions do not account for actual machine or material properties leading to trial molding requirements
Solution Approach 1:
The system performs preliminary virtual molding simulations to generate provisional molding conditions before actual production, which reduces initial setup time. This preliminary action creates a starting point that can be refined based on actual trial results.
Solution Approach 2:
The system implements feedback by comparing intermediate molding conditions obtained from trial moldings with the provisional conditions from simulation, then optimizing the conditions iteratively. This feedback loop ensures that actual machine and material properties are accounted for, improving the reliability of final molding conditions.
2Manufacturing precision
If numerous trial molding operations are conducted to account for actual machine properties, then molding condition accuracy is improved, but setup time increases significantly
Solution Approach 1:
Virtual molding simulations are conducted as a preliminary step to generate provisional molding conditions that serve as a starting point for trial moldings, reducing the number of trials needed to achieve accurate conditions.
Solution Approach 2:
The system uses feedback from intermediate trial molding conditions to optimize and refine the provisional conditions, systematically reducing the number of trials required while maintaining high accuracy in the final molding conditions.
3Ease of manufacture
If provisional molding conditions from virtual simulation are used directly, then setup process is simplified, but the conditions may not be consistent with actual molding requirements
Solution Approach 1:
The system generates provisional molding conditions through virtual simulation as a preliminary step, providing a simplified starting point that maintains consistency with theoretical requirements while enabling easy initial setup.
Solution Approach 2:
The system compares intermediate conditions from actual trial moldings with the provisional conditions to identify inconsistencies, then optimizes the conditions to ensure both simplicity of setup and consistency with actual molding requirements.
