Electrostatic Chucking Mat for Cutting Plotter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting plotters face issues with cutting thin media due to the electrostatic chucking mat bending, causing the medium to rise and potentially fail during the cutting process, as the ends of the mat may not adhere properly, leading to inconsistencies in cutting performance.
Innovation Solution
A cutting plotter medium supporting device with a removably connected support and an electrostatic chucking mat that generates a chucking force, allowing the mat to move reciprocally while being supported, ensuring consistent adhesion and stability of the medium during cutting, using a positioning structure and locking mechanism for secure attachment to the cutting plotter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional medium supporting sheet is used for thin medium cutting, then the medium can be supported and easily removed after cutting, but the ends of the supporting sheet bend during cutting causing the medium to rise up and cutting to fail
Solution Approach 1:
The patent applies the dynamics principle by making the medium supporting sheet movable rather than fixed. The supporting sheet is configured to move reciprocally in the feed direction through a driving mechanism, allowing it to dynamically adjust its position during cutting operations. This movement prevents the sheet from bending at the ends and maintains stable contact with the medium throughout the cutting process, resolving the contradiction between cutting reliability and sheet stability.
2Reliability
If the medium supporting sheet is made movable to prevent bending, then cutting reliability improves, but the device complexity increases due to additional driving mechanisms
Solution Approach 1:
The patent applies the merging principle by integrating the driving mechanism for the medium supporting sheet with the existing medium feeding mechanism of the cutting plotter. The supporting sheet is driven by the same feed mechanism that handles the medium, combining two functions into one system. This integration avoids adding separate complex driving mechanisms while still achieving the benefit of movable supporting sheet, thus resolving the contradiction between cutting reliability and device complexity.
3Stability of the object's composition
If the electrostatic chucking mat is fixed to prevent movement, then structural stability is maintained, but the medium cannot be properly fed and cut through the mat
Solution Approach 1:
The patent applies the dynamics principle to the electrostatic chucking mat by configuring it to move reciprocally in the feed direction while maintaining electrostatic chucking force. The mat is driven by the medium feeding mechanism to move back and forth, allowing the medium to be fed through it during cutting operations. This dynamic movement enables continuous cutting throughput while the electrostatic force maintains stable adhesion between the mat and medium, resolving the contradiction between structural stability and cutting productivity.
