Front Insertion Port Recording Device with Inversion Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recording devices with inversion paths for inverting the recording target medium tend to increase in size when additional functionalities like manual feeding and document reading are incorporated, leading to a need for compact multi-functionality without size expansion.
Innovation Solution
A recording device design featuring a first conveyance path for recording, a second conveyance path coupled downstream and upstream of the recording unit for inverted surface handling, and an insertion port for manual feeding, along with a reading unit integrated into the second conveyance path to enable document reading without additional size increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a recording device includes an inversion path for inverting the recording target medium to perform recording on both surfaces, then the device can achieve multi-functionality, but the size of the device is significantly increased
Solution Approach 1:
The patent makes the second conveyance path serve multiple functions: it acts as both the inversion path for double-sided recording and the manual feeding path for inserting recording target media from the front surface. This multi-functional design allows the device to achieve versatility without adding separate dedicated paths, thereby preventing device size increase.
Solution Approach 2:
The patent merges the inversion path and manual feeding path into a single second conveyance path. By combining these two functions that were traditionally implemented as separate paths, the device achieves multi-functionality while avoiding the space required for duplicate conveyance structures.
2Adaptability or versatility
If a recording device with inversion path is provided with additional functions like manual feeding and document reading, then the device achieves enhanced functionality, but the device size increases due to additional conveyance paths and reading units
Solution Approach 1:
The second conveyance path is designed to serve three functions simultaneously: inversion path for double-sided recording, manual feeding path for inserting media from front, and document reading path for scanning documents. This universal design allows enhanced functionality without requiring separate dedicated paths for each function.
Solution Approach 2:
The patent combines inversion path, manual feeding path, and document reading path into a single integrated second conveyance path, eliminating the need for multiple separate structures and preventing device size increase.
3Adaptability or versatility
If a reading unit is added to the second conveyance path for document reading, then the device achieves multi-functionality, but the device size increases
Solution Approach 1:
The reading unit is integrated into the second conveyance path, which already serves as inversion path and manual feeding path. By placing the reading unit in this multi-functional path rather than creating a separate dedicated reading path, the device achieves document reading capability without proportionally increasing size.
