Inkjet Printer Waste Liquid Box Inter-Tray Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of inkjet printers with a waste liquid unit attachment section located lower than the feeder-cassette attachment section leads to an increase in the printer's height, compromising its compactness.
Innovation Solution
The inkjet printer incorporates a first waste liquid box located in the space between the first and second trays, allowing for a larger waste liquid capacity without increasing the printer's height, and features a holder that supports the waste liquid box, enabling easy mounting and demounting.

Engineering Contradiction Analysis
1Quantity of substance
If the waste liquid unit attachment section is located lower than the feeder-cassette attachment section, then the waste liquid capacity can be increased, but the height of the inkjet printer increases
Solution Approach 1:
The waste liquid box is repositioned from the lower section to the space between trays in the vertical stacking arrangement, utilizing horizontal space between trays rather than extending the vertical height. This dimensional shift allows increased waste liquid capacity while maintaining compact printer height.
Solution Approach 2:
The waste liquid box is nested within the space between the first and second trays, utilizing the vertical stacking arrangement's inter-tray space. This nesting approach allows the waste liquid unit to be integrated into the existing tray structure without adding external height to the printer.
2Length of stationary object
If the waste liquid box is placed in the space between trays, then the printer height is restrained, but the waste liquid box may interfere with tray operations
Solution Approach 1:
The waste liquid box is extracted as a separate, removable component supported by an independent holder structure. This allows the waste liquid box to be mounted or demounted independently from the trays, preventing interference with tray operations while maintaining its position in the inter-tray space.
Solution Approach 2:
The waste liquid storage function is segmented into a separate box supported by a dedicated holder, distinct from the tray structures. This segmentation allows independent operation of trays and the waste liquid box, eliminating potential interference while maintaining compact integration.

AI summary
A liquid discharging apparatus, having a housing, a first tray for storing a printable medium, a second tray for storing a printable medium, a liquid discharging head, and a first waste liquid storage, is provided. The second tray is located at a position lower than the first tray. The liquid discharging head has nozzles for discharging liquid. The first waste liquid storage is demountably mounted in the housing. The first waste liquid storage is configured to store waste liquid being the liquid discharged from the nozzles of the liquid discharging head. The first waste liquid storage is located between the first tray and the second tray.
