Waste Liquid Container Recess for Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waste liquid containers in existing systems often experience faulty connections due to waste ink adhesion, which can impede electrical connectivity and data transfer.
Innovation Solution
The waste liquid container design features a recess portion on its mounting face and bottom face below the waste liquid inlet, positioning the recess between the inlet and connection terminals, preventing waste liquid from flowing towards the terminals and ensuring it accumulates in designated areas, thus minimizing adhesion and maintaining connection integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waste liquid container is mounted with connection terminals exposed, then electrical connectivity is enabled, but waste liquid adhesion causes faulty connections
Solution Approach 1:
The recess portion acts as an intermediary barrier between the waste liquid inlet and the connection terminals. It intercepts waste liquid flow path, preventing direct contact between waste liquid and connection terminals, thus eliminating the harmful adhesion effect while maintaining electrical connectivity
2Device complexity
If connection terminals are positioned near waste liquid inlet for compact design, then device complexity is reduced, but waste liquid flow directly contacts terminals causing connection failure
Solution Approach 1:
The recess portion introduces a vertical dimension (depth) to separate the connection terminals from the waste liquid inlet horizontally. This spatial arrangement in three dimensions allows compact overall design while preventing direct linear contact between waste liquid and terminals

AI summary
A waste liquid container includes a waste liquid vessel having a mounting face, a first side face, and a bottom face that are outer surfaces intersecting each other, a waste liquid inlet disposed on the mounting face, a circuit board having a connection terminal disposed along the first side face, and a first recess portion that opens in the mounting face and the bottom face below the waste liquid inlet. In the waste liquid container, when a width direction is defined as a direction in which both the mounting face and the bottom face extend, the first recess portion is disposed at a position between the waste liquid inlet and the connection terminal in the width direction.
