Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct work is performed by contacting the electric line, then work efficiency and range are improved, but safety risk increases
Solution Approach 1:
The patent introduces an insulating extension stick as an intermediary tool between the worker and the electric line. The stripping device is mounted on this insulating extension stick, allowing the worker to perform stripping operations on live wires from a safe distance without direct contact, thus maintaining safety while enabling efficient work on high-voltage lines
Solution Approach 2:
The patent replaces manual mechanical stripping operations with an automated stripping device that rotates automatically. The device includes a rotating mechanism with stripping blades that automatically cut and remove the wire insulation through rotational motion, eliminating the need for manual handling and improving both safety and efficiency
2Adaptability or versatility
If separate tools are used for stripping and taping operations, then functional versatility is maintained, but device complexity and working time increase
Solution Approach 1:
The patent combines multiple functions (stripping and taping) into a single integrated device. The stripping device includes both stripping blades for removing insulation and a taping mechanism for applying insulating tape to the exposed wire. This integration allows workers to perform both operations with one tool, reducing device complexity and working time while maintaining functional versatility
Solution Approach 2:
The patent designs the stripping device as a universal tool that can perform multiple functions: stripping different types of wire insulation, applying insulating tape, and working on various voltage levels. The device includes interchangeable components and adjustable mechanisms that enable it to handle diverse wire types and stripping requirements, making it a versatile multi-functional tool
3Ease of operation
If manual wire leading and gripping operations are performed, then operational control is maintained, but working time and complexity increase
Solution Approach 1:
The patent incorporates a wire feeding mechanism that automatically feeds the wire into the stripping position. The device includes a wire guide and automatic feeding system that positions the wire correctly without manual intervention, allowing the wire to feed itself into the stripping blades. This self-service mechanism significantly reduces working time while maintaining operational control through simple activation by the worker
4Productivity
If the stripping device is rotated continuously, then stripping efficiency is improved, but device stability and control difficulty increase
Solution Approach 1:
The patent employs a dynamically balanced rotating mechanism where the stripping blades and other components are strategically positioned to achieve balance during rotation. The insulating extension stick and mounting structure are designed to minimize vibration and maintain stability even during continuous rotation at high speeds, allowing efficient stripping operations without compromising device stability or controllability

AI summary
Proposed are a device which is used as both a taping device and a stripping device and is used for stripping or taping a coating of an extra-high-voltage wire in a live wire state and, more particularly, an automatic opening and closing stripping device for an indirect live wire having wire stripping and taping functions, and methods for stripping and taping an indirect live wire using the automatic opening and closing device. The automatic opening and closing stripping device for an indirect live wire having wire stripping and taping functions allows an insulation stripping or taping operation to be performed on a wire in a live wire state while not being close to the wire, thus securing safety, allows a stripping operation and various taping operations to be performed by using one equipment.
