Innovation Solution
A device with a rotatable arm and clamping means that allows for precise orientation and movement of processing tools along any desired angle, enabling quick and precise cutting of complex shapes without manual sheet rotation, using a combination of cutting tools like pressure, ultrasonic, and laser cutting, and suction for enhanced precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual rotation and alignment of the textile sheet is used to enable the laser to cut complex shapes, then the cutting capability for complex shapes is improved, but the processing time increases and precision deteriorates
Solution Approach 1:
Instead of rotating the textile sheet manually to enable the laser to cut complex shapes, the invention inverts the approach by making the laser device itself rotatable. The laser is mounted on a rotatable arm that can rotate 360 degrees, allowing the laser to approach the textile sheet from any angle automatically, thereby eliminating manual sheet rotation and enabling complex shape cutting without increasing processing time
Solution Approach 2:
The invention introduces dynamic elements to the previously static laser positioning system. The laser is mounted on a rotatable arm with rotational movement capability, and the entire positioning system can dynamically adjust the laser's position and orientation in both longitudinal and transverse directions, enabling automatic adaptation to complex cutting paths without manual intervention
2Adaptability or versatility
If manual rotation and alignment of the textile sheet is used to enable the laser to cut complex shapes, then the cutting capability for complex shapes is improved, but the cutting precision deteriorates
Solution Approach 1:
Instead of manually rotating the textile sheet which introduces alignment errors, the invention makes the laser device rotatable with precise control. The laser mounted on the rotatable arm can be positioned and oriented with high precision through motorized control, eliminating the imprecision inherent in manual sheet rotation and alignment operations
Solution Approach 2:
The invention replaces the manual mechanical rotation and alignment of the textile sheet with an automated motorized positioning system. The rotatable arm with motorized control and electronic positioning replaces manual operations, significantly improving cutting precision through consistent, repeatable, and precisely controllable movements
3Ease of operation
If the laser is positioned on the textile sheet in advance and the sheet is manually turned, then the processing setup is simplified, but the processing speed decreases and labor intensity increases
Solution Approach 1:
The invention maintains the simplicity of pre-positioning the laser while dramatically increasing processing speed through automation. The laser is positioned on the textile sheet in advance using the rotatable arm, but subsequent movements along complex paths are executed automatically by the motorized positioning system, eliminating time-consuming manual turning operations and increasing productivity
Solution Approach 2:
The invention enables the laser positioning system to serve itself by automating the positioning and movement operations. The motorized rotatable arm and positioning system can automatically adjust the laser's position and orientation without human intervention, reducing labor intensity while maintaining operational simplicity and increasing processing speed
