Rear Display Placement for Image Reader Cover Clearance

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image reading apparatuses face interference issues when a movable member needs to move while the reader is not in use, as it can collide with fixed components, such as displays or other structural elements, which can lead to mechanical limitations and potential document jamming during transport.

Innovation Solution

The image reading apparatus design includes a movable cover that rotates within a trajectory clear of any fixed members, such as a display, ensuring unobstructed movement and minimizing the risk of interference, allowing for efficient operation and document handling without collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a display is provided above the reader in the image reading apparatus, then the operational efficiency and user interface are improved, but the movable member may interfere with the display when moving within the reader's non-reading region

Engineering Contradiction:

Improveuser interface accessibilityVSAvoidmechanical interference risk

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The display is positioned on the rear side of the image reading apparatus, utilizing the depth dimension (front-to-back axis) rather than occupying the horizontal or vertical space above the reader. This spatial reconfiguration allows the movable cover to move freely in the horizontal plane without interfering with the display, which is now located behind the reader's non-reading region.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the movable cover is designed to move freely within the reader's non-reading region, then the operational flexibility is improved, but the risk of collision with fixed components increases

Engineering Contradiction:

Improvecover movement flexibilityVSAvoidcollision risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The display is extracted from the space above the reader and repositioned to the rear side of the apparatus. This extraction removes the obstacle from the movable cover's trajectory, allowing the cover to move freely within the reader's non-reading region without risk of collision, thereby maintaining both flexibility and reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Area of stationary object

If the display is positioned above the reader, then the space utilization is improved, but the movable member's movement trajectory is blocked

Engineering Contradiction:

Improvedisplay placement spaceVSAvoidcover movement trajectory

Core Design Contradiction:

Area of stationary objectVSLength of moving object

Solution Approach 1:

Instead of placing the display in the horizontal space above the reader (which would block the cover's movement), the display is positioned in the depth dimension on the rear side of the apparatus. This allows the cover to move freely along its trajectory without obstruction, while the display occupies the rear space that would otherwise be unused.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An image reading apparatus includes a reader configured to read an image, and a movable member that is movable when the reader is not reading the image, and configured to move within a region where a fixed member fixed above the reader is not present on a movement trajectory of the movable member.
