Solution Overview

Problem

Conventional cutting plotters face issues with jamming, incomplete cuts, and complex operation when cutting paper sheets, particularly with thin or weak materials, due to inadequate transmission of driving force and manual adjustment of cutting conditions, leading to poor cutting quality and increased operator complexity.

Innovation Solution

A cut target medium driving type cutting plotter with a supporting sheet that removably supports the paper sheet between a driving roller and a driven roller, using vector element data for cutting and storing setting conditions for different media types, allowing automatic detection of reference marks and optimal projection adjustment of the cutting blade.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the driving roller directly transmits driving force to the paper sheet, then the paper sheet can be moved in the first direction, but the driving force is not transmitted to the product causing jamming and incomplete cuts

Engineering Contradiction:

Improvecutting completenessVSAvoidjamming prevention

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

A supporting sheet is introduced as an intermediary between the driving roller and the paper sheet. The supporting sheet receives driving force from the driving roller and transmits it to the paper sheet, ensuring complete cutting while preventing jamming. The supporting sheet acts as a mediator that solves the force transmission problem without directly contacting the product.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual adjustment of cutting conditions is performed, then operator control is maintained, but the process becomes complex and time-consuming

Engineering Contradiction:

Improveautomatic adjustmentVSAvoidsetting adjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects reference marks on the paper sheet and self-adjusts cutting conditions without operator intervention. The cutting plotter reads the reference mark information and autonomously determines optimal cutting parameters, eliminating manual adjustment time while maintaining cutting quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from reference mark detection to automatically adjust cutting conditions. By reading the reference mark position and characteristics, the system receives feedback about the paper sheet properties and automatically modifies cutting parameters accordingly, reducing operator complexity and adjustment time.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the cutting blade projects deeply to cut through thick materials, then cutting capability is improved, but thin materials are damaged and cutting quality deteriorates

Engineering Contradiction:

Improvematerial thickness rangeVSAvoidcutting quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The cutting blade projection amount is dynamically adjusted based on the detected material type. The system changes the blade projection depth according to whether thin or thick materials are being cut, optimizing cutting quality for each material thickness while maintaining versatility across different material types.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the physical parameter of blade projection amount based on material characteristics detected from reference marks. By adjusting this parameter according to material thickness, the system achieves both adaptability to different materials and high cutting quality without damaging thin materials.

Inventive Principle:

Principle #35Parameter changes

AI summary

A cut target medium driving type cutting plotter, where a cut target medium to be cut is driven in a first direction and a cutting unit is driven in a second direction perpendicular to the first direction, thereby moving the cutting unit in a two-dimensional direction relative to the cut target medium to make the cutting unit to be selectively brought into press contact with and separated from the cut target medium to cut the cut target medium in a desired shape, the cut target medium driving type cutting plotter includes a cut target medium supporting sheet to removably support the cut target medium on a surface opposite to the cutting unit. Preferably, the cut target medium is driven in the first direction together with the cut target medium supporting sheet, and the cut target medium supported on the cut target medium supporting sheet is cut by the cutting unit.
