Solution Overview
Problem
Existing fabric cutting apparatuses require laborious and inconvenient manual alignment of fabric rolls, often necessitating two operators to ensure correct positioning and alignment for precise cutting, which is inefficient and costly, especially when forming multilayers.
Innovation Solution
A cutting apparatus equipped with a manual command element, such as a joystick, that allows for precise alignment and movement control of the fabric roll, enabling single-operator operation for positioning, cutting, and rewinding, using motorized means for alignment and rewinding to simplify the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment of fabric roll is performed by operator, then alignment can be achieved, but the operation becomes laborious and requires two operators to ensure correct positioning
Solution Approach 1:
The patent replaces manual mechanical alignment operations with an automated alignment system that uses sensors to detect fabric position and actuators to adjust the fabric roll automatically. This substitution eliminates the need for multiple operators while maintaining high alignment precision, directly resolving the contradiction between precision and operational complexity.
Solution Approach 2:
The alignment system performs self-adjustment by continuously monitoring fabric position through sensors and automatically correcting misalignment through actuators. The system serves itself by detecting and correcting its own positioning errors without requiring external manual intervention from multiple operators, thereby reducing operational complexity while preserving precision.
2Manufacturing precision
If automatic alignment system is used, then alignment precision is improved, but the system becomes expensive and complex
Solution Approach 1:
The alignment system is divided into separate functional modules: sensors for detection, controllers for processing, and actuators for adjustment. This segmentation allows each component to be optimized independently and facilitates easier maintenance and upgrading, reducing overall system complexity while maintaining high precision alignment capabilities.
Solution Approach 2:
The alignment system is designed with multi-functional capabilities that can handle various fabric types and widths through adjustable parameters. The same sensor-actuator framework serves multiple alignment scenarios, reducing the need for specialized equipment for different tasks and thereby lowering overall system complexity while maintaining precision across applications.
3Manufacturing precision
If two operators are used for alignment and cutting, then correct positioning can be ensured, but productivity decreases due to increased labor requirements
Solution Approach 1:
The patent replaces the mechanical coordination between two operators with an automated alignment system that uses sensors and actuators to achieve precise positioning automatically. This substitution eliminates the need for multiple human operators while maintaining positioning accuracy, thereby increasing productivity by reducing labor requirements without sacrificing precision.
Solution Approach 2:
The system performs self-alignment and self-positioning functions that previously required coordinated manual operations from two operators. The automated detection and adjustment mechanisms handle positioning tasks independently, enabling single-operator operation or even fully automated operation, thus improving productivity while maintaining the same level of positioning accuracy.
