Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices fail to accurately cut objects due to mismatched setting conditions stored in the device and the actual object's properties, leading to inappropriate cutting.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If setting conditions are stored in a storage device based on classification of cutting objects, then the cutting device can operate with predefined parameters, but the setting conditions may not correspond to the actual cutting object properties
Solution Approach 1:
The system performs preliminary measurement by moving the cutting blade toward the cutting object to detect the actual contact position, then uses this detected position to determine appropriate cutting conditions before actual cutting begins. This preliminary detection action ensures that the cutting parameters match the actual object properties rather than relying solely on pre-stored classifications.
Solution Approach 2:
The system incorporates feedback by detecting the actual contact position between the cutting blade and cutting object, then using this detected information to adjust and determine the cutting conditions. This closed-loop feedback mechanism ensures that the cutting parameters are optimized based on real-time detection of the actual object properties.
2Device complexity
If the cutting blade position is fixed based on stored settings, then the device structure is simple, but it cannot adapt to variations in actual cutting object properties
Solution Approach 1:
The system transitions from a static fixed position approach to a dynamic adaptive approach by incorporating a detector that measures the actual contact position. The cutting blade position is no longer fixed but is dynamically adjusted based on the detected contact position, allowing the system to adapt to variations in cutting object properties while maintaining a relatively simple overall structure.
Solution Approach 2:
The system changes the cutting parameters (specifically the blade position and cutting conditions) based on the detected contact position. Instead of using fixed predetermined parameters, the system dynamically modifies these parameters according to the actual measured properties of the cutting object, enabling adaptation without complex structural changes.
3Productivity
If the cutting device uses predetermined cutting positions, then the operation is fast, but the cutting precision deteriorates when object properties vary
Solution Approach 1:
The system performs a quick preliminary detection movement to identify the actual contact position before the main cutting operation. This preliminary action is fast and does not significantly impact productivity, but it enables precise determination of cutting parameters, thereby maintaining both high cutting speed and high precision even when object properties vary.
Solution Approach 2:
The system uses rapid feedback detection to quickly determine the actual contact position and adjust cutting parameters accordingly. This feedback mechanism operates efficiently during the setup phase, allowing the system to maintain high productivity while ensuring precise cutting through real-time parameter adjustment based on detected object properties.

AI summary
A cutting device includes a platen, a mounting portion, a first movement mechanism, a second movement mechanism, a detector, 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. The processes include acquiring cutting data, acquiring a contact position output by the detector when the cutting blade comes into contact with the holding member, and controlling the first movement mechanism in accordance with the cutting data to move the mounting portion and the holding member to a cutting start position. The processes include controlling the second movement mechanism, at the cutting start position, to move the mounting portion in the third direction to a cutting position set on the basis of the contact position, and controlling the first movement mechanism in accordance with the acquired cutting data to perform cutting processing.
