## 4 Detailed Design of the Conductive Center Pole Based on the Innovative Design Method
### Design Matrix Decoupling Based on TRIZ  
To decouple the design matrix \(A\) for the conductive module structure of the center pole in Figure 10, the position and length of the center pole need to be calibrated after the center pole is tightened to ensure that the conductive module can be screwed together with the center pole to complete the alignment and contact of the electrodes. However, whether the conductive module can be conducted is related to the position of the electrode in the circumferential direction, the distance in the axial direction, and the relative position of the anti-rotation structure. It is necessary to ensure the alignment of the electrodes and to ensure that the electrodes are in full contact and are not affected by the angle of the anti-rotation structure, that is, to eliminate the influence of elements \(A_{12}\), \(A_{13}\), \(A_{21}\), and \(A_{23}\) in matrix \(A\). Furthermore, the required effects or effects that need to be eliminated must be established according to functional requirements. Ideally, to realize the conduction of the conductive module in the center pole, it is necessary for the conductive module to completely align its electrodes and ensure sufficient contact at the same time after the connection is completed. In order to avoid wire entanglement during the installation, an anti-rotation structure was designed to make the conductive module and the center pole move in-sync, remaining relatively static. However, the conductive modules in the two sections of the center pole move with the center pole, resulting in a relative rotation, which causes the electrodes of the two sections to move relative to each other, making it difficult to ensure alignment. This problem is the alignment of the two conductive poles, which belongs to the physical conflict in TRIZ. When the two sides of the key subsystem conflict only appear on one side of a certain space, the space separation method can be used to resolve the physical conflict. [PERSON] of the University of Bath in the United Kingdom proposed that there is a corresponding relationship between the separation principle for resolving physical conflicts and the invention principle for resolving technical conflicts. There are multiple invention principles corresponding to one separation principle, and more ideas for solving problems are provided [40]. The corresponding relationship is shown in Table 2.  
The solution to spatial separation includes 10 principles of invention. To solve the problem of electrode alignment in the conductive module, the invention principle seven \"nesting\" and the invention principle 17 \"space dimension change\" can be used. \"Nesting\" refers to embedding an object in another object or allowing something to pass through the cavity of another object. \"Space dimensionality change\" refers to changing one-dimensional linear motion into two-dimensional plane motion or three-dimensional space motion. With the help of these two principles, and considering the rotational movement of the conductive module, the electrode can be designed as a combination of a ring and a dot. The dot-shaped electrode is placed in the center of the circular ring electrode, and the electrode at the other end is the dot-shaped electrode at the corresponding position, which avoids the problem that the two electrodes cannot be aligned due to the rotational movement. The structure before and after the improvement is shown in Figure 11.  
This design ensures that when the center pole drives the conductive module to rotate, the electrodes at both ends can always be aligned in the circumferential direction and the center position and are not affected by the center rod's circumferentially calibrated position and the angle of the anti-rotation structure. Therefore, \(A_{12}\) and \(A_{13}\) in the design matrix \(A\) can be eliminated, and the alignment before contact can also be satisfied, that is, \(A_{23}\) can also be eliminated. Matrix \(A\) is improved to matrix \(B\), as shown below:  
\[B=
