Solution Overview

Problem

Conventional cutting apparatuses are inefficient in reducing cutting time when processing a single pattern, as they are optimized for cutting multiple patterns with connected cutting lines.

Innovation Solution

A cutting apparatus that calculates and adjusts the cutting time based on various arrangement angles of a pattern relative to the cutting directions, determining the optimal angle to minimize cutting time by simultaneously moving the cutting blade and object in perpendicular directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If patterns are arranged to lie next to each other with connected cutting lines, then cutting time is shortened for multiple patterns, but cutting time cannot be reduced when a single pattern is to be cut

Engineering Contradiction:
Improvecutting timeVSAvoidapplicability to single pattern cutting
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the arrangement angle parameter of the pattern to optimize cutting time. By rotating the pattern at predetermined angle intervals (0°, 45°, 90°, 135°) and calculating cutting time for each angle, the system determines the optimal arrangement angle that minimizes cutting time, making the system adaptable to both single and multiple pattern cutting scenarios

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces dynamic angle adjustment capability where the pattern arrangement angle is not fixed but can be changed and optimized. The control device dynamically selects the best arrangement angle based on calculated cutting times, enabling adaptive optimization for different cutting scenarios including single pattern cutting

Inventive Principle:
Principle #15Dynamics

2Productivity

If the cutting blade and object move simultaneously in perpendicular directions, then cutting efficiency is improved, but the complexity of control increases

Engineering Contradiction:
Improvecutting efficiencyVSAvoidcontrol mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control device is designed to perform multiple functions: it calculates cutting time for different arrangement angles, determines the optimal angle, controls the pattern rotation, and manages the coordinated movement of the cutting blade and object. This multi-functionality reduces the need for separate control systems while maintaining cutting efficiency

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically calculates and determines the optimal arrangement angle without requiring manual intervention. The control device self-manages the angle selection and coordination of movements based on pre-calculated cutting times, reducing operational complexity while maintaining high cutting efficiency

Inventive Principle:
Principle #25Self-service

AI summary

A cutting apparatus includes a moving device configured to move a cutting blade and an object in a first direction and in a second direction differing from the first direction, relative to each other and a control device configured to cause the apparatus to calculate first cutting time lengths required to cut a pattern at a plurality of arrangement angles when an arrangement angle of the pattern relative to the first or second direction is changed by a first unit angle, determine one of the arrangement angles, which is shortest with respect to the first cutting time length or not more than a first threshold, and control the moving device so that the movement of the cutting blade in the first direction and the movement of the object in the second direction are simultaneously executed, with a result that the pattern is cut at the determined arrangement angle.
