Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixing devices are used to bend a PCB, then the PCB can be bent, but the bending angle is limited and the PCB may be damaged due to lack of precise control
Solution Approach 1:
The patent employs adjustable abutting members that can be positioned at different locations along the PCB, allowing the bending angle and bending position to be dynamically adjusted. The abutting members can be moved along the PCB length and fixed at desired positions, enabling precise control of bending parameters while adapting to different bending requirements.
Solution Approach 2:
The patent changes the physical parameters of the bending system by using abutting members with adjustable positions and heights. By modifying the position of abutting members along the PCB and adjusting their height, the system achieves precise control over bending angle and radius, resolving the contradiction between precision and adaptability.
2Ease of operation
If fixed bending devices are used, then the structure is simple, but the bending angle cannot be easily adjusted or controlled
Solution Approach 1:
The bending device is segmented into multiple independent abutting members that can be individually adjusted. Each abutting member can be positioned and fixed independently, allowing flexible control of the bending shape without requiring a complex integrated adjusting mechanism.
Solution Approach 2:
The abutting members are designed to be self-adjusting through simple positioning mechanisms that allow operators to directly set the desired bending parameters without complex control systems. The members can be manually positioned and locked into place, providing ease of operation with minimal mechanical complexity.

AI summary
The present invention discloses a device for bending sheets. The device includes at least two abutting members which are respectively defined as a first abutting member and a second abutting member. The sheet comprises a first outside surface and a second outside surface opposite to the first outside surface. The first abutting member is fixedly connected to the second outside surface of the sheet. The second abutting member attached to the second outside surface of the sheet is rotatably connected to the first abutting member. The first abutting member and the second abutting member are rotatably connected together and capable of being locked with each other so as to obtain a desired curvature of the sheet, which hardly damages the sheet.
