Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices struggle to accurately cut patterns with direction changes, as they fail to adjust the cutting blade orientation effectively, leading to suboptimal cutting quality.
Innovation Solution
A cutting device that includes a processor to acquire the hardness-correspondence value of the cutting object, set an offset amount for rotation correction, and adjust the cutting data to ensure accurate cutting along pattern shapes by changing the cutting blade's orientation at direction change sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed offset amount is used for rotation correction at direction change sections, then the cutting device can perform basic rotation correction, but the cutting quality deteriorates when cutting hard materials or thick objects
Solution Approach 1:
The patent implements dynamic adjustment of the offset amount based on the actual cutting conditions. The system calculates different offset amounts for different direction change sections by considering the hardness and thickness of the cutting object, transforming the fixed offset approach into a dynamic, condition-dependent adjustment mechanism that optimizes cutting quality for each specific scenario
Solution Approach 2:
The patent changes the parameter of offset amount from a fixed value to a variable that depends on material hardness and thickness. By establishing a relationship between these parameters and the required offset correction, the system adapts the rotation correction to match the specific cutting conditions, thereby improving cutting quality across different material types
2Manufacturing precision
If the cutting blade orientation is not corrected at direction change sections, then the cutting device operates with simple control logic, but the cutting accuracy deteriorates when the pattern direction changes by a predetermined amount or more
Solution Approach 1:
The patent performs preliminary calculation of the offset amount before actual cutting occurs. By pre-calculating the required rotation correction based on the pattern data and material properties, the system prepares the correction parameters in advance, allowing the cutting process to execute smoothly without real-time complexity
Solution Approach 2:
The patent introduces an intermediary calculation step that determines the offset amount based on the relationship between cutting object hardness, thickness, and direction change angle. This intermediary parameter serves as a bridge between the raw cutting data and the final blade orientation control, simplifying the overall control logic while maintaining accuracy
3Manufacturing precision
If a uniform cutting approach is used for all materials, then the cutting device operates with simple settings, but the cutting quality deteriorates for hard or thick cutting objects
Solution Approach 1:
The patent applies local quality by adjusting the offset amount specifically for direction change sections based on the local properties of the cutting object (hardness and thickness). Rather than uniformly changing all cutting parameters, the system selectively adjusts only the rotation correction offset where it is needed, maintaining simplicity while improving quality
Solution Approach 2:
The system performs preliminary acquisition of hardness-correspondence values and thickness information before setting the offset amount. By gathering this material-specific data in advance, the system can configure the appropriate rotation correction parameters without adding complexity to the actual cutting operation

AI summary
A cutting device includes a platen, a mounting portion, a movement mechanism, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes including acquiring a hardness-correspondence value corresponding to a hardness of a cutting object placed on the platen, acquiring cutting data for cutting a pattern from the cutting object, setting, based on the hardness-correspondence value, an offset amount used for a rotation correction to a greater value when the hardness of the cutting object is hard than when the hardness of the cutting object is soft, correcting, using the set offset amount, data, of the cutting data, corresponding to a direction change section, and performing cutting processing to cut the cutting object using a cutting blade, by controlling the movement mechanism in accordance with the corrected cutting data.
