Solution Overview

Problem

Existing recording devices face operational issues due to paper dust generated during the cutting process, which can cause mechanical troubles and affect the accuracy of the recording process.

Innovation Solution

The recording device incorporates a cutting unit with a movable blade and a fixed blade, along with removing units and a paper-dust holding unit, to effectively remove and contain paper dust generated during cutting, thereby preventing operational disruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a cutting unit is added to cut the medium after recording, then the medium can be divided into separate portions, but paper dust is generated that causes operational troubles

Engineering Contradiction:

Improvemedium processing capabilityVSAvoidpaper dust contamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The harmful element (paper dust) is extracted from the working area by introducing a removing unit that actively removes paper dust generated during cutting, and a paper-dust holding unit that collects and isolates it, preventing contamination of the recording unit and other components

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A removing unit acts as an intermediary between the cutting unit and the recording unit, intercepting and removing paper dust before it can contaminate the recording area, thus protecting the system from harmful effects

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of time

If cutting is performed immediately after recording, then the workflow is continuous, but paper dust may affect the accuracy of the recording process

Engineering Contradiction:

Improveworkflow efficiencyVSAvoidrecording accuracy

Core Design Contradiction:

Loss of timeVSManufacturing precision

Solution Approach 1:

The removing unit is positioned and configured to remove paper dust immediately as it is generated during cutting, preventing contamination before it can affect the recording accuracy. The paper-dust holding unit is also prepared in advance to collect and contain the dust

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a removing unit and paper-dust holding unit are added to remove paper dust, then operational reliability improves, but device complexity increases

Engineering Contradiction:

Improveoperational reliabilityVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The removing unit and paper-dust holding unit are integrated into a cohesive dust management system that works in conjunction with the existing cutting unit and recording unit, combining multiple functions into a unified structure that minimizes overall system complexity

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A recording device includes: a recording unit configured to perform recording on a medium transported from upstream in a transport direction toward downstream; a cutting unit configured to cut the medium on which recording is performed by the recording unit; a discharging unit configured to transport, to the downstream in the transport direction, the medium on which recording is performed by the recording unit and the medium cut by the cutting unit; and a removing unit configured to remove paper dust generated when the medium is cut by the cutting unit.
