Reversing Unit Frame Coupling to Prevent Printer Frame Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices, such as ink jet printers, face the issue of frame distortion when a reversing unit is detached due to applied forces, which is not adequately addressed in current designs.
Innovation Solution
The recording device incorporates a configuration with a base portion, first and second frames fixed to the base portion on opposite sides of the reversing unit, and a coupling portion coupling the frames at a position away from the base, using synthetic resin for the frames and metal for the coupling portion, with the coupling portion fixed by screws and featuring a bent shape to enhance strength and reduce weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reversing unit is detached from the frame, then it is easy to cope with medium jams, but frame distortion occurs around the reversing unit
Solution Approach 1:
The frame is divided into multiple segments (first frame, second frame, third frame) that are coupled together at positions away from the base portion. This segmentation allows the reversing unit to be detached for jam removal while the distributed coupling structure prevents overall frame distortion.
Solution Approach 2:
Different portions of the frame structure are given different properties: the coupling portions are positioned away from the base to provide structural support where needed, while the area around the reversing unit maintains flexibility for detachment. This local differentiation resolves the contradiction between stability and ease of operation.
2Stability of the object's composition
If frames are coupled at positions away from the base portion, then frame distortion is reduced, but device complexity increases
Solution Approach 1:
The frame is segmented into multiple coupled portions positioned away from the base. This segmentation strategy reduces frame distortion by distributing structural support points, while the modular nature of the segmentation keeps the complexity manageable through standardized coupling mechanisms.
3Stability of the object's composition
If coupling portions are positioned away from the base portion, then frame stability is improved, but wiring support becomes more difficult
Solution Approach 1:
The coupling portions serve multiple functions: they provide structural support to prevent frame distortion, maintain frame stability, and simultaneously serve as pathways for wiring. This multi-functionality resolves the contradiction by integrating wiring support into the structural coupling elements themselves.

AI summary
A recording device includes a recording unit configured to perform recording on a medium, a reversing unit configured to bend and reverse the medium on which recording was performed by the recording unit and that is transported along a transport path and guide the medium toward a recording unit side, a base portion disposed below the reversing unit, a first frame fixed to the base portion and disposed on a side of a first side surface of the reversing unit to hold the reversing unit, a second frame fixed to the base portion and disposed on a side of a second side surface different from the first side surface to hold the reversing unit, and a coupling portion coupling the first frame and the second frame to each other at a position away from the base portion.
