Solution Overview

Problem

The recording device in JP-A-2021-121488 is susceptible to displacement of the line head or cap unit due to vibration or impact during transportation, leading to potential defects.

Innovation Solution

A recording device with a movable moving portion and a regulating member that can be attached and detached to control the movement of the moving portion, ensuring proper alignment and preventing displacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the recording device is made movable for transportation, then ease of operation is improved, but the line head or cap unit may be displaced from predetermined position due to vibration or impact

Engineering Contradiction:

Improveease of transportationVSAvoidposition stability of line head and cap unit

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The regulating member is installed in advance to counteract the harmful effect of vibration and impact before they can cause displacement. The regulating portion contacts the moving portion to prevent displacement from occurring during transportation, rather than correcting displacement after it happens.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The regulating member acts as an intermediary component between the moving portion (line head and cap unit) and the external vibration/impact forces. By introducing this intermediate regulating portion, the direct transmission of vibration and impact to the moving portion is blocked, preventing displacement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a regulating member is added to prevent displacement, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveposition stability of line head and cap unitVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The regulating member is designed as a separate, detachable component with a specific regulating portion that can be independently installed and removed. This segmentation allows the regulating function to be added without redesigning the entire device structure, minimizing the increase in overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The regulating member is designed to be attachable and detachable, allowing the system to transition between having regulation functionality and not having it. This dynamic configuration enables the device to adapt to different transportation needs without permanently increasing structural complexity.

Inventive Principle:

Principle #15Dynamics

AI summary

A recording device includes a moving portion that is movable in a moving direction intersecting a horizontal direction, and a regulating member that includes a regulating portion and is attachable to and detachable from a contact position where the regulating portion comes into contact with a part of the moving portion, in which the regulating member regulates movement of the moving portion in the moving direction by the regulating portion coming into contact with a part of the moving portion.
