Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single material supply mechanism is used, then the device complexity is reduced, but the reliability decreases due to operation failures interrupting the molding process
Solution Approach 1:
The material supply mechanism is divided into multiple independent supply paths (first supply path and second supply path), each with its own supply mechanism. This segmentation allows the system to maintain material supply capability even when one path fails, thereby improving reliability without requiring a completely redundant complex system.
Solution Approach 2:
The system changes the operational parameters of the supply mechanisms by controlling them to operate alternately or simultaneously. The control section adjusts the supply parameters based on the operational state, allowing flexible operation modes that balance reliability and complexity requirements.
2Reliability
If dual supply mechanisms are implemented, then the reliability improves by preventing operation failures, but the device complexity increases
Solution Approach 1:
The first and second supply paths are merged into a unified material supply system with a common material storage section and control section. This merging approach allows the system to achieve redundancy and improved reliability while sharing common components, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The material storage section and control section serve multiple functions by supporting both the first and second supply paths. The control section can manage both supply mechanisms, allowing them to operate in different modes (alternate or simultaneous operation), which provides multi-functionality without proportionally increasing complexity.
3Stability of the object's composition
If multiple supply mechanisms operate simultaneously, then the material supply stability is improved, but the control complexity increases
Solution Approach 1:
The control section monitors the operational state of both supply mechanisms and adjusts their operation accordingly. When a failure is detected in one path, the control section provides feedback to switch to or increase operation of the other path, ensuring stable material supply while managing control complexity through intelligent monitoring and adjustment.
Solution Approach 2:
The system transitions from static single-path operation to dynamic multi-path operation. The supply mechanisms can dynamically switch between alternate and simultaneous operation modes based on operational requirements and failure states, providing flexibility in maintaining material flow consistency without requiring permanently complex control structures.
