Waste Liquid Container Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waste liquid containers often experience contact failures due to waste liquid leakage adhering to circuit board connecting terminals, disrupting information transmission and reception.
Innovation Solution
A waste liquid container design with a recessed portion and notch configuration that positions the connecting terminal inside the recessed portion and guides leaked liquid away from the terminal, preventing adherence and ensuring reliable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting terminal is disposed on the mounting surface, then electrical connection is facilitated, but waste liquid adheres to the connecting terminal causing contact failure
Solution Approach 1:
The connecting terminal is nested inside the recessed portion of the accommodating case, which is positioned below the waste liquid introducing portion. This nesting arrangement protects the connecting terminal from waste liquid while maintaining electrical connection functionality through the substrate connecting portion.
Solution Approach 2:
The solution transitions from a two-dimensional surface arrangement to a three-dimensional spatial arrangement by creating a recessed portion that extends downward from the mounting surface. This vertical dimensionality change allows the connecting terminal to be positioned below the waste liquid introduction point, preventing liquid adherence while maintaining connectivity.
2Object-affected harmful factors
If the connecting terminal is positioned lower to avoid liquid, then waste liquid adherence is reduced, but electrical connection becomes more difficult
Solution Approach 1:
The substrate connecting portion acts as an intermediary element that extends from the mounting surface down to the connecting terminal inside the recessed portion. This intermediary structure facilitates electrical connection to the lowered terminal while maintaining compatibility with the mounting portion's substrate connecting structure.
3Productivity
If the waste liquid introducing portion is positioned higher, then liquid discharge is improved, but leaked liquid flows toward the connecting terminal
Solution Approach 1:
The accommodating case features an asymmetric structure with the waste liquid introducing portion positioned at the upper part and the connecting terminal positioned at the lower part within the recessed portion. This asymmetric arrangement ensures that waste liquid flows downward away from the connecting terminal, preventing contact failure while maintaining discharge efficiency.

AI summary
A waste liquid container includes an accommodating case which includes a mounting surface which is an external surface that faces internally in a mounting direction and a first side surface and a second side surface which are outside surfaces extending in a direction intersecting a width direction, a waste liquid introducing portion which is connected to a discharging portion, and a circuit board including a connecting terminal which is electrically connected to a substrate connecting portion. The accommodating case includes a recessed portion which opens on the mounting surface and the first side surface and allows a projecting portion to be inserted therein, when being mounted on the mounting portion, and a notch which opens on the mounting surface and the second side surface vertically below the waste liquid introducing portion. The connecting terminal is disposed inside the recessed portion.
