Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an opening/closing mechanism is added to the three-dimensional forming apparatus to control material discharge, then the precision and control of forming processes is improved, but the device complexity increases
Solution Approach 1:
The system pre-calculates and pre-determines the opening/closing operations of the flow path based on the three-dimensional shape data and forming parameters. The opening/closing commands are generated in advance during the data preparation phase, allowing the mechanism to operate automatically without real-time complex decision-making, thus improving precision while managing complexity through advance planning
Solution Approach 2:
A control unit acts as an intermediary between the forming data and the opening/closing mechanism. This control unit processes the forming data, determines the appropriate opening/closing operations, and generates the corresponding commands. The intermediary simplifies the overall system architecture by centralizing the control logic and isolating the complexity within a dedicated processing component
2Adaptability or versatility
If forming data is generated manually for modified apparatus configurations, then adaptability to new configurations is improved, but the time and effort required for data preparation increases
Solution Approach 1:
The system automatically generates the opening/closing commands by analyzing the three-dimensional shape data and forming parameters itself. The data generation process is self-service in nature, where the control unit autonomously determines the required opening/closing operations without requiring manual intervention or external assistance, thus reducing time loss while maintaining adaptability to different configurations
Solution Approach 2:
The system adapts to different apparatus configurations by changing the parameters and conditions in the forming data generation process. By modifying the control parameters, flow path characteristics, and operating conditions in the data, the system can accommodate various configurations automatically without requiring complete manual data recreation, thus maintaining versatility while reducing preparation time
3Manufacturing precision
If the opening/closing mechanism operates frequently to control material discharge precisely, then the manufacturing precision is improved, but the productivity decreases due to increased operation cycles
Solution Approach 1:
The opening/closing mechanism operates periodically according to the pre-calculated forming data and three-dimensional shape requirements. By establishing regular operating cycles and patterns based on the geometry of the object being formed, the system achieves precise discharge control at critical points while maintaining overall productivity through efficient periodic operation rather than continuous random adjustments
Solution Approach 2:
The system maintains continuous useful action by optimizing the opening/closing operations to occur only when necessary for precision control. The forming process continues without interruption, with the opening/closing mechanism operating seamlessly integrated into the continuous material discharge process. This ensures that productivity is maintained while achieving precision control through targeted, continuous optimization rather than discontinuous stop-start operations

AI summary
A three-dimensional forming system includes a three-dimensional forming apparatus and a control device. The three-dimensional forming apparatus includes a nozzle that discharges a forming material, an opening/closing mechanism that opens or closes a flow path connected to the nozzle, a moving mechanism that changes a relative position between the forming table and the nozzle, and a control unit that perform a control based on forming data. The control device includes a forming data generating unit that analyzes path data including a path indicating a movement direction and a movement distance of the nozzle and a discharge parameter indicating discharging of the forming material, generates the forming data by adding an opening/closing command for driving the opening/closing mechanism to the path data, and transmits the forming data to the three-dimensional forming apparatus.
