Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a coupling arrangement is introduced between the ejector and energy storage device, then force transmission during charging is improved, but device complexity increases
Solution Approach 1:
A coupling arrangement acts as an intermediary mechanism between the ejector and energy storage device. This coupling arrangement includes a lever mechanism that amplifies force during the charging process, transmitting the ejector's movement force to charge the energy storage device more effectively. The coupling arrangement serves as a mediator that resolves the force transmission issue while managing the added complexity through a structured mechanical interface.
2Force
If the ejector is in direct contact with the energy storage device, then force transmission efficiency is improved, but noise increases due to idle movements
Solution Approach 1:
The energy storage device is maintained in a preloaded state through the coupling arrangement, which prepares the system in advance for the next operational cycle. This preliminary action ensures that the energy storage device is already charged and ready, eliminating idle movements and associated noises during operation. The preloaded state is achieved through the lever mechanism that continuously maintains optimal force transmission readiness.
3Ease of operation
If the energy storage device is preloaded, then operation smoothness is improved, but device complexity increases
Solution Approach 1:
The coupling arrangement with the lever mechanism enables the energy storage device to automatically maintain its preloaded state through the mechanical interaction with the ejector. The system serves itself by using the ejector's own movement to charge the energy storage device, eliminating the need for external intervention or complex control systems. This self-service mechanism achieves operation smoothness while managing complexity through automatic mechanical feedback.
