Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a bulk feeder supplies components in a bulk state to a supply region, then the component supply system can operate with simplified structure, but the number of collectable components varies leading to unsatisfactory supply state
Solution Approach 1:
The supply region is divided into multiple areas, and the state recognition section derives supply state information for each area separately. This segmentation allows for more precise control of component distribution, ensuring consistent supply state while maintaining the simplified bulk feeder structure.
Solution Approach 2:
The state recognition section continuously monitors the supply state by imaging the supply region and derives information about component distribution. This feedback is used by the conveyance control section to adjust vibration conveyance operations, maintaining reliable and consistent component supply.
2Productivity
If vibration is applied to conveyance path to convey multiple components, then components can be supplied to supply region, but variation in collectable component number reduces productivity
Solution Approach 1:
The conveyance control section dynamically adjusts vibration conveyance operations based on real-time supply state feedback. The vibration parameters are modified according to the current component distribution, ensuring optimal component supply and maximizing the number of collectable components while maintaining consistency.
Solution Approach 2:
The system uses feedback from the state recognition section to continuously monitor and adjust the vibration conveyance operations. This closed-loop control ensures that productivity is maximized while maintaining consistent supply state by adapting to variations in component distribution.
3Ease of operation
If defined conveyance operation is executed by bulk feeder, then component supply can be controlled, but variation in collectable components persists
Solution Approach 1:
The supply region is pre-divided into multiple areas with defined characteristics. The state recognition section is configured to derive supply state information for each predetermined area, enabling proactive adjustment of conveyance operations before supply issues arise, thus maintaining reliable component supply while keeping operations simple.
Solution Approach 2:
The system maintains ease of operation by using automated feedback control. The state recognition section continuously provides information about component distribution in each area, and the conveyance control section automatically adjusts operations based on this feedback, eliminating the need for manual intervention while ensuring satisfactory supply state.
