Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting plotters face issues with accurately cutting objects due to unreliable holding of the object by the holding member, especially when the adhesive layer's adhesion is unsuitable for the object's type, leading to potential displacement and inaccurate cutting.
Innovation Solution
A cutting apparatus with a holding member featuring a wireless tag that contains cutting information, including relative moving speed, pressing force, and correction data, which is read by a control unit to ensure precise cutting, and a pressing unit to securely hold the object during the cutting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesive layer of the holding member is used to hold the object, then the object can be held on the holding member, but the adhesion may be unsuitable for the object type causing displacement and inaccurate cutting
Solution Approach 1:
The patent applies parameter changes by adjusting cutting parameters (pressing force, relative moving speed, correction amount) based on the object type detected through the wireless tag. The control unit modifies these parameters dynamically to match the specific object being cut, ensuring both reliable holding and precise cutting for different material types.
Solution Approach 2:
The patent implements feedback through the wireless tag system that provides information about the object type to the control unit. The control unit uses this feedback information to automatically adjust cutting parameters and pressing force, creating a closed-loop control system that ensures optimal performance for each object type.
2Device complexity
If the object is held by adhesive alone without additional pressing mechanism, then the holding member structure is simple, but the object may displace during cutting affecting accuracy
Solution Approach 1:
The patent applies dynamics by making the pressing force adjustable and dynamic rather than fixed. The pressing unit's pressing force is controlled based on the object type detected by the wireless tag, allowing the system to adapt the holding pressure dynamically to match different object characteristics while maintaining cutting accuracy.
Solution Approach 2:
The patent changes the pressing force parameter dynamically based on object type information from the wireless tag. The control unit adjusts the pressing unit's output force according to the specific object being cut, ensuring optimal holding without requiring a completely different holding mechanism structure.
3Device complexity
If cutting parameters are fixed for all object types, then the control system is simple, but cutting accuracy varies across different object types
Solution Approach 1:
The patent implements parameter changes by automatically adjusting cutting parameters (pressing force, relative moving speed, correction amount) based on the object type detected through the wireless tag. The control unit modifies these parameters dynamically to match the specific object being cut, ensuring both reliable holding and precise cutting for different material types.
Solution Approach 2:
The patent implements feedback through the wireless tag system that provides information about the object type to the control unit. The control unit uses this feedback information to automatically adjust cutting parameters and pressing force, creating a closed-loop control system that ensures optimal performance for each object type.
