Solution Overview
Problem
Existing rewinding systems for thin-film tapes in electronic devices lack efficiency in processing and adapting to user-specific size and length requirements, necessitating improved process efficiency for secondary processing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single rewinding apparatus is used to wind thin-film tape on rolls, then the device complexity is low, but the productivity is insufficient to meet manufacturing demands
Solution Approach 1:
The patent combines multiple rewinding apparatuses (first and second rewinding apparatuses with mounting members) into a single integrated system. This allows simultaneous winding of thin-film tape on multiple rolls across different mounting members, thereby increasing overall productivity while maintaining a unified control structure that manages the complexity of coordinating multiple winding operations
Solution Approach 2:
The system divides the rewinding function into separate mounting members (first mounting member, second mounting member, etc.) that can operate independently or in coordination. Each mounting member can hold multiple re-winding rolls and perform winding operations separately, allowing the system to process multiple tape streams simultaneously while maintaining modular complexity management
2Loss of time
If sequential winding and loading operations are performed, then the device complexity is low, but the loss of time increases due to waiting periods
Solution Approach 1:
The patent implements continuous operation by enabling multiple mounting members to perform winding and loading operations in an overlapping sequence. While one mounting member is winding tape, another can be loading completed rolls, eliminating idle waiting periods. The system coordinates these continuous actions across multiple apparatuses to maintain uninterrupted production flow
Solution Approach 2:
The system prepares mounting members and re-winding rolls in advance for subsequent winding operations. Completed rolls are pre-positioned on loading apparatuses, and mounting members are pre-configured with multiple rolls, allowing immediate transition between winding and loading operations without downtime or reconfiguration delays
3Productivity
If multiple mounting members with independent rolls are used, then the productivity increases through parallel processing, but the device complexity increases due to coordination requirements
Solution Approach 1:
Each mounting member is designed as a universal unit capable of performing multiple functions: holding multiple re-winding rolls, rotating to present different rolls, and transferring rolls to loading apparatuses. This multi-functionality allows any mounting member to take on various roles in the production sequence, simplifying the coordination mechanism as all components follow the same operational patterns regardless of their position in the system
