Liquid-Receiving Tray Opening for Ink Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face challenges in preventing ink leakage when legs are positioned other than at the four corners, leading to deformation, increased installation time, and risk of ink leakage due to the placement of ink-receiving containers and engagement portions at the bottom portion.
Innovation Solution
A recording apparatus with a liquid-receiving tray that has an opening portion higher than the bottom, allowing for the receipt of leaking liquid and enabling the attachment of leg portions to support the apparatus, while maintaining the freedom of configuration and preventing ink leakage by delaying the flow of liquid when tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legs are provided at positions other than the four corners of the bottom portion, then the degree of freedom of configuration is improved, but the ink-receiving container may become deformed or installation becomes complex
Solution Approach 1:
The bottom portion is divided into a solid base portion and a liquid-receiving tray portion with an opening. Legs can be attached to either the base portion or the tray portion, providing multiple configuration options without requiring complex modifications to the overall structure.
Solution Approach 2:
The liquid-receiving tray serves multiple functions: it receives leaked liquid, provides an attachment surface for legs at various positions, and maintains structural integrity. This multi-functionality allows legs to be positioned flexibly while avoiding the need for separate reinforcement structures.
2Adaptability or versatility
If legs are attached to the ink-receiving container, then configuration flexibility is improved, but the ink-receiving container may become deformed
Solution Approach 1:
The bottom portion is segmented into a solid base portion that provides structural support and a liquid-receiving tray portion that receives leaked liquid. Legs can be attached to the solid base portion to avoid deforming the tray, or the tray itself can serve as the attachment surface when configuration flexibility is needed.
Solution Approach 2:
The solid base portion acts as an intermediary between the legs and the liquid-receiving tray. When legs are attached to the base portion, the tray remains undisturbed and can freely perform its liquid-receiving function without structural deformation.
3Adaptability or versatility
If holes are formed in the ink-receiving container for leg passage, then leg attachment is enabled, but ink may easily leak out when the apparatus is tilted
Solution Approach 1:
Instead of forming holes through the liquid-receiving tray, the invention extracts the leg attachment function to the solid base portion below the tray. This separates the leg attachment pathway from the liquid-receiving cavity, eliminating holes in the tray and preventing ink leakage while maintaining leg attachment capability.
Solution Approach 2:
The solid base portion serves as an intermediary structure that provides attachment points for legs without requiring holes in the liquid-receiving tray. The tray remains intact as a continuous barrier, preventing ink from leaking through while legs are securely attached to the base portion above or below the tray level.
4Adaptability or versatility
If multiple ink-receiving containers are provided to avoid legs, then leg placement flexibility is improved, but installation time increases and regions without containers are formed
Solution Approach 1:
The liquid-receiving tray is designed as a single multi-functional component that simultaneously receives leaked liquid and provides attachment surfaces for legs at multiple positions. This eliminates the need for multiple separate containers and reduces installation time while maintaining leg placement flexibility.
Solution Approach 2:
Instead of using multiple containers arranged in space to avoid legs, the invention utilizes the vertical dimension by allowing the single tray to extend and provide attachment surfaces at different heights and positions. Legs can be attached at various locations on the tray or on the solid base portion without requiring multiple horizontal containers.
