Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional extrusion methods are used without designation information, then the manufacturing process is simple, but the center of gravity and weight cannot be accurately controlled
Solution Approach 1:
The system performs preliminary calculations to determine the required extrusion path and material amount before actual manufacturing. The information processing apparatus calculates the path and extruding amount based on designation information, creating model data in advance that guides the extruding unit to achieve precise center of gravity control
Solution Approach 2:
The system establishes a feedback loop where designation information about desired center of gravity and weight is input, the information processing apparatus calculates required extrusion parameters, and the extruding unit executes the manufacturing process. This closed-loop approach ensures accurate control by comparing intended specifications with actual manufacturing parameters
2Manufacturing precision
If the extruding amount and path are not precisely controlled, then the manufacturing process is simple, but the weight and center of gravity cannot be set to desired values
Solution Approach 1:
The system dynamically adjusts the extrusion path and extruding amount based on the desired weight and center of gravity specifications. The information processing apparatus calculates optimal extrusion parameters in real-time, allowing the extruding unit to adapt its movement and material deposition to achieve precise weight control while maintaining manufacturing feasibility
3Ease of operation
If manual adjustment of center of gravity and weight is used, then equipment complexity is low, but manufacturing precision and user convenience are reduced
Solution Approach 1:
The information processing apparatus automatically performs calculations and generates model data without requiring manual intervention during the manufacturing process. Users simply input designation information about desired center of gravity and weight, and the system self-calculates the extrusion path and material amount, providing ease of operation while maintaining precision through automated computation
