Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanical system is used for material manipulation, then it can generate simple 2D braided preforms, but it lacks adaptability for 3D braiding and complex carrier paths
Solution Approach 1:
The patent replaces complex mechanical systems with an electromagnetic system consisting of a planar array of electromagnetic actuators. This substitution enables carriers to follow complex 3D paths with high adaptability while avoiding the complexity of mechanical linkages and moving parts. The electromagnetic field can be dynamically controlled to guide carriers along any desired trajectory.
Solution Approach 2:
The patent transitions from 2D mechanical braiding systems to a 3D electromagnetic system. The planar array of electromagnetic actuators creates a three-dimensional carrier path space, enabling carriers to move not only in the plane but also in the vertical dimension, thus achieving complex 3D braided structures.
2Adaptability or versatility
If existing electromagnetic systems are used to replace mechanical systems, then carrier path adaptability improves, but the ability to maintain line tension during carrier motion is lost
Solution Approach 1:
The patent employs periodic electromagnetic actuation to maintain line tension on carriers. The electromagnetic actuators in the planar array are activated in a sequential, periodic manner as the carrier passes over them, ensuring continuous tension maintenance throughout the carrier's motion path. This periodic activation pattern allows the system to dynamically adjust tension forces.
3Adaptability or versatility
If complex mechanical systems are implemented to enable higher carrier path adaptability, then 3D braiding becomes possible, but manufacturing and implementation become difficult due to scale and dimensional complexity
Solution Approach 1:
The patent divides the electromagnetic actuation system into a planar array of discrete, identical electromagnetic actuators. Each actuator is a standardized component that can be independently manufactured and then assembled into the complete system. This segmentation approach simplifies manufacturing compared to creating large complex mechanical systems, as each electromagnetic element is relatively simple and can be produced using standard electromagnetic component fabrication processes.
