Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional winding system is used, then the wire can be fed to the carrier, but the wire tension becomes unstable causing defects
Solution Approach 1:
The wire tension control mechanism employs a feedback system where the resistance provided by the wire guiding device is dynamically adjusted based on the pulling force of the wire. The rotor moves in response to tension changes, automatically regulating the resistance to maintain stable wire tension throughout the winding process, preventing defects caused by unstable tension.
Solution Approach 2:
The wire guiding device acts as an intermediary between the wire feeding device and the carrier. It introduces a controllable resistance element that mediates the wire tension, allowing the system to maintain stable tension by adjusting the resistance based on the wire's pulling force during winding.
2Strength
If wire tension is increased to prevent slippage, then wire stability improves, but wire splitting or twisting occurs
Solution Approach 1:
The wire tension control mechanism transitions from a static tension system to a dynamic one. The rotor is designed to move freely along the wire's pulling direction, allowing the resistance provided by the wire guiding device to dynamically adjust according to real-time tension conditions. This dynamic adjustment prevents both slippage and wire damage by maintaining optimal tension levels throughout the winding process.
Solution Approach 2:
The mechanism changes the resistance parameter dynamically based on wire tension conditions. As the wire pulls with varying force during winding, the rotor position changes, which in turn adjusts the resistance value. This parameter change ensures the wire receives appropriate tension control without excessive force that could cause splitting or twisting.
3Device complexity
If a fixed resistance mechanism is used, then structure is simple, but it cannot adapt to varying wire tension requirements
Solution Approach 1:
The wire tension control mechanism is designed to self-regulate without external control systems. The rotor automatically positions itself in response to wire pulling force, and the wire guiding device automatically provides the appropriate resistance. This self-service mechanism achieves adaptive tension control while maintaining relatively simple structure, avoiding the need for complex sensors, motors, or control circuits.
