Sheet Body Cutting Synchronization to Prevent Wrinkles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet body cutting methods often result in wrinkles and damage due to mismatched speeds between the movable clamp and winding rolls, leading to potential breaks during cutting.
Innovation Solution
A sheet body cutting method and device that synchronizes the movement of holding, grip conveyance, and delivering units to accurately position and convey the sheet body, minimizing wrinkles by controlling the relative displacement of these units to ensure precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the movable clamp moves faster to increase delivery speed, then productivity is improved, but wrinkles are formed on the sheet body due to speed mismatch with winding rolls
Solution Approach 1:
The patent applies dynamics by making the delivery system adaptable through synchronized control of multiple units. The holding units, grip conveyance units, and delivering units are dynamically coordinated to move at matched speeds, allowing the system to maintain high productivity while preventing wrinkles through real-time speed synchronization rather than fixed-speed operation.
Solution Approach 2:
The patent implements feedback control through the synchronous delivering mechanism where the movement of holding units, grip conveyance units, and delivering units is coordinated based on their interdependent relationships. This feedback-based synchronization ensures that each unit moves at the appropriate speed to maintain sheet body tension and positioning accuracy, preventing wrinkle formation while achieving high delivery speeds.
2Device complexity
If the movable clamp moves independently without synchronization, then device complexity is reduced, but sheet body damage occurs due to wrinkle formation
Solution Approach 1:
The patent merges the control of holding units, grip conveyance units, and delivering units into a unified synchronous delivering system. By combining these units into an integrated control mechanism, the patent achieves reliable sheet body handling without requiring overly complex independent control systems for each unit, thus balancing device complexity with sheet body integrity.
Solution Approach 2:
The patent segments the delivery system into distinct functional units (holding units, grip conveyance units, delivering units) that operate independently but are synchronized through a coordinated control mechanism. This segmentation allows each unit to perform its specific function while maintaining overall system reliability through synchronized operation, preventing sheet body damage without excessive complexity.
3Manufacturing precision
If multiple units operate simultaneously to improve delivery accuracy, then manufacturing precision is improved, but device complexity increases due to coordinated control requirements
Solution Approach 1:
The patent applies universality by designing the synchronous delivering system where holding units, grip conveyance units, and delivering units serve multiple functions. These units not only perform their primary functions but also contribute to positioning accuracy and wrinkle prevention through their coordinated movement, reducing the need for separate specialized components and simplifying the overall control architecture.

AI summary
A sheet body is gripped (bound) by grip conveyance units, and conveyed as the grip conveyance units are displaced in this state. At the same time as this conveyance, the sheet body is held by delivering units, and delivered by a predetermined amount by the delivering units. After that, the sheet body is cut in predetermined size and shape by cutting molds.
