Engineering Contradiction Analysis
1Productivity
If machine is used to carry out coil binding, then productivity is improved, but manufacturing precision deteriorates due to inability to form appropriate angle and curvature manually
Solution Approach 1:
The device performs preliminary action by automatically forming the binding edge at the required angle and curvature before the coil insertion process. The binding edge forming mechanism pre-shapes the paper stack's binding edge with precise angular orientation and curved geometry, ensuring that when the coil is subsequently inserted through the punched holes, it can spin through smoothly without manual adjustment. This eliminates the need for manual formation while maintaining high precision.
Solution Approach 2:
The machine performs self-service by incorporating automated mechanisms that independently complete the angle formation and curvature creation tasks without human intervention. The binding edge forming mechanism automatically adjusts and shapes the paper stack's binding edge according to predetermined parameters, allowing the system to self-correct and maintain precision throughout the automated binding process.
2Manufacturing precision
If manual labor is used for coil binding, then manufacturing precision is maintained, but productivity deteriorates due to time consumption
Solution Approach 1:
The patent replaces manual mechanical operations with automated mechanical systems. The binding edge forming mechanism uses controlled mechanical actuators to automatically create the required angles and curvatures on the paper stack's binding edge. The coil insertion mechanism uses automated positioning and feeding systems to insert coils through punched holes at the correct orientation. This substitution eliminates manual labor while maintaining precision through controlled mechanical processes.
Solution Approach 2:
The device employs parameter changes by automatically adjusting binding parameters such as angle orientation, curvature radius, and positioning coordinates through programmable controls. The system can modify these parameters to accommodate different book sizes and binding requirements without manual intervention, maintaining precision through digital parameter control rather than manual skill.
3Manufacturing precision
If manual formation of angle and curvature is performed, then manufacturing precision is maintained, but device complexity increases due to additional manual adjustment mechanisms
Solution Approach 1:
The patent merges multiple functions into integrated mechanisms. The binding edge forming mechanism combines angle formation, curvature creation, and positioning functions into a single automated assembly. Rather than having separate manual adjustment mechanisms for each parameter, the system integrates these functions into one coordinated mechanism that automatically performs all necessary formations in sequence, reducing overall device complexity.
Solution Approach 2:
The automated binding edge forming mechanism serves multiple functions: it forms the binding edge at the correct angle, creates the required curvature, and positions the paper stack for coil insertion. This multi-functional mechanism replaces what would otherwise require multiple separate manual adjustment devices, thereby reducing device complexity while maintaining manufacturing precision.

AI summary
A fully automatic coil binding machine includes a main body, a width adjusting device, a paper clamping device, a resting device, a coil driving device, a cutting device and a driving device. The main body has a coil guiding slot and a guiding row of teeth. The width adjusting device may be used to adjust the width of the coil guiding slot. The paper clamping device has a paper slot, in which a stack of paper may be placed. The binding edge of the stack of paper may rest on the resting device, so that its curvature may be adjusted. The coil driving device may move the coil located in the coil guiding slot along the guiding row of teeth into the paper slot and drive the coil to spin through the holes of the stack of paper.
