Solution Overview

Problem

Existing medium ejecting apparatuses struggle to align the front-ends of variously sized media, particularly smaller media, when ejected onto a tray, leading to difficulties in organizing imaged media.

Innovation Solution

The medium ejecting apparatus incorporates a medium regulating member with load pressing portions and an engaging portion, held by a holding member that allows the regulating member to swing vertically and pivot, ensuring proper alignment and loading of media on the tray.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a fixed medium regulating member is used, then the structure is simple, but the front-ends of variously sized media cannot be aligned properly on the tray

Engineering Contradiction:
Improvealignment precision of media front-endsVSAvoidstructure complexity of medium regulating member
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The medium regulating member is designed with dynamic movement capabilities, allowing it to swing in the vertical direction and pivot along a rotation axis. This enables the regulating member to adapt its position and orientation to accommodate various media sizes and achieve proper alignment on the tray, resolving the contradiction between alignment precision and structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a medium regulating member with swinging and pivoting capabilities is added, then media alignment is improved, but the device complexity increases

Engineering Contradiction:
Improveease of media alignmentVSAvoidcomplexity of holding member mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The medium regulating member utilizes the weight and movement of the media themselves to achieve alignment. As media are ejected onto the tray, the regulating member automatically swings and pivots to accommodate different media sizes without requiring external control mechanisms, thereby improving ease of operation while minimizing the complexity of the holding member.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If the medium regulating member is fixed, then the device is compact, but smaller media cannot be properly aligned and loaded

Engineering Contradiction:
Improvealignment precision of small mediaVSAvoidspace occupied by regulating member mechanism
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The medium regulating member is designed with dynamic movement capabilities, allowing it to swing in the vertical direction and pivot along a rotation axis. This enables the regulating member to adapt its position and orientation to accommodate various media sizes and achieve proper alignment on the tray, resolving the contradiction between alignment precision and structural simplicity.

Inventive Principle:
Principle #15Dynamics
