Solution Overview

Problem

Conventional recording systems are bulky due to the protrusion of paper discharge trays from the recording apparatus, which increases the overall size of the system.

Innovation Solution

A recording system configuration that includes a recording apparatus with a discharge path and a transport mechanism, where the medium is transported internally to a post-processing apparatus, and a loading portion above the transport mechanism loads the medium, allowing for a compact design by eliminating the need for a protruding paper discharge tray.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a paper discharge tray protrudes from the recording apparatus, then the medium can be discharged and stored, but the overall size of the recording system becomes large

Engineering Contradiction:
Improvemedium discharge and storageVSAvoidrecording system size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent repositions the loading portion from a horizontal protrusion to a vertical arrangement above the transport mechanism. The medium is loaded from above onto the transport mechanism rather than from a side-mounted tray, effectively utilizing the vertical dimension to eliminate the need for a horizontal discharge tray protrusion.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If the loading portion is disposed above the transport mechanism, then the recording system size is reduced, but the medium loading process must be precisely controlled

Engineering Contradiction:
Improverecording system sizeVSAvoidloading process control
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The loading portion is positioned at a height that aligns with the transport mechanism, creating a level loading surface. This equipotential arrangement allows the medium to be smoothly transferred from the loading portion to the transport mechanism without requiring complex lifting or positioning mechanisms, thereby reducing control complexity despite the vertical arrangement.

Inventive Principle:
Principle #12Equipotentiality

3Productivity

If multiple mediums are loaded simultaneously, then productivity is improved, but transport failures may increase

Engineering Contradiction:
Improvemedium loading efficiencyVSAvoidtransport reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The transport mechanism is divided into multiple independent transport paths or segments, each capable of handling individual mediums. This segmentation allows multiple mediums to be transported simultaneously while maintaining independent control over each path, thereby preventing transport failures from affecting all mediums and maintaining high reliability alongside improved productivity.

Inventive Principle:
Principle #1Segmentation

AI summary

A recording system includes: a recording apparatus; a post-processing apparatus; and a transport apparatus which transports the medium to which the recording is performed to the post-processing apparatus, and the transport apparatus includes a transport mechanism which transports a medium to which the recording is performed to the post-processing apparatus, and a loading stand which loads the discharged medium without transporting the medium to which the recording is performed to the post-processing apparatus.
