Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional tape attaching apparatus is used, then the structure is simple, but the installation space is large and productivity is low
Solution Approach 1:
The apparatus divides the tape attaching function into multiple rotating heads (first rotating head and second rotating head) arranged at equiangular intervals around a rotation center. Each rotating head independently performs tape attaching at different positions, enabling parallel processing and significantly improving productivity while maintaining a compact footprint through the rotational arrangement.
Solution Approach 2:
The patent transitions from a linear or planar arrangement of attaching components to a rotational configuration around a central axis. By arranging multiple rotating heads at equiangular intervals in a circular pattern and rotating them to different angular positions, the system achieves multi-position tape attaching capability in a compact space, effectively utilizing the third dimension (rotation) to resolve the contradiction between productivity and installation space.

3Manufacturing precision
If tape is attached to the electrode plate, then short circuit is prevented, but the tape attachment position accuracy is low
Solution Approach 1:
The control unit coordinates the rotation of multiple rotating heads and the feeding of the electrode plate based on positional feedback. The system monitors the angular position of each rotating head and the position of the electrode plate, adjusting their movements to ensure that tape attaching occurs at precisely controlled positions. This feedback mechanism enables high positioning accuracy despite the complexity of coordinating multiple rotating components.
Solution Approach 2:
The rotating heads are positioned at predetermined equiangular intervals around the rotation center, and the control unit pre-coordinates their rotation angles with the electrode plate feeding position. This preliminary arrangement and coordination ensure that when tape attaching is performed, the rotating heads are already in the correct positions to achieve high precision attachment, reducing the need for complex real-time adjustments.
4Productivity
If multiple rotating heads are used, then productivity is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple rotating heads and their control functions into a unified rotational system around a single rotation center. The control unit integrates the coordination of multiple rotating heads and the electrode plate feeding into one centralized control mechanism. This merging approach enables parallel tape attaching operations that improve productivity while managing device complexity through systematic integration rather than independent control of each component.

Function Achieved in This Case
The apparatus reduces installation space, improves productivity, and enhances the accuracy of tape attachment, minimizing the risk of short circuits by using a rotating head system with multiple heads and tension control mechanisms.
Implementation Method 1
the rotating head may be configured to adsorb the non-adhesive surface at the tape transfer point and stop the adsorption of the non-adhesive surface at the tape attachment point
Implementation Method 2
The rotating head may push the tape toward the electrode plate so that the adhesive surface adheres to the electrode plate at the tape attachment point
