Printer Waste Liquid Container Rear Access Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing recording apparatuses face challenges in accessing the waste liquid container for maintenance due to its rear placement, which increases the device's size in the depth direction when positioned alongside the operation panel at the front.
Innovation Solution
The recording apparatus incorporates an accommodating unit that places the waste liquid container between the front wall and the liquid ejecting head in the depth direction, allowing easy access from the front side without overlapping the operation panel, thus maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the waste liquid container is arranged side by side with the operation panel in the depth direction at a front position, then the operator can easily access both components, but the recording apparatus increases in size in the depth direction
Solution Approach 1:
The patent repositions the waste liquid container from a front-depth arrangement to a rear-depth arrangement, utilizing the depth dimension to separate the container from the operation panel. This dimensional reorganization allows the container to be accessible from the rear while maintaining a compact front profile, thus resolving the contradiction between accessibility and device size.
2Length of stationary object
If the waste liquid container is placed at a rear position, then the apparatus maintains a compact size, but the container becomes difficult to access for maintenance
Solution Approach 1:
The patent segments the access path for the waste liquid container by providing a separate access mechanism from the rear of the apparatus. This segmentation allows the container to be positioned at the rear for compactness while creating an independent access route that maintains ease of maintenance, thus resolving the contradiction between compact size and accessibility.

AI summary
A recording apparatus includes an apparatus main body including: a transport unit that transports a medium; a liquid ejecting head that is provided above a transport path for the medium and performs recording by ejecting liquid onto the medium; and an accommodating unit that accommodates a waste liquid container configured to store waste liquid discharged from the liquid ejecting head, wherein a front surface of the apparatus main body is provided with a front wall and an operable operation unit, which are adjacent to each other in a width direction, and the accommodating unit is located between the front wall and the liquid ejecting head in a depth direction at a position that does not overlap the operation unit in the width direction.
