Solution Overview
Problem
Liquid receiving devices and liquid ejecting apparatuses face issues with liquid scattering due to inertial forces when liquid holding units move or stop, causing overflow and contamination within the apparatus.
Innovation Solution
A liquid receiving device with a liquid holding unit featuring protruding units and pathway units that slow down liquid flow, reducing the amount of liquid reaching the peripheral wall and preventing overflow, combined with a discharge mechanism and attitude retention mechanism to maintain the liquid holding unit's horizontal attitude during movement and stopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid holding unit moves or stops rapidly, then the liquid ejecting apparatus can operate efficiently, but liquid flows due to inertial force and may overflow from the cap member
Solution Approach 1:
The liquid holding unit is divided into a bottom unit and a peripheral wall unit that protrudes upward, creating a liquid accumulation unit with internal structures (protruding units) that segment the liquid flow path. This segmentation allows the liquid to be controlled in stages during movement and stopping, preventing overflow while maintaining operational efficiency
Solution Approach 2:
Protruding units are introduced as intermediary structures within the liquid accumulation unit. These units act as mediators that intercept and slow down the liquid flow caused by inertial forces during movement and stopping, preventing the liquid from directly reaching the peripheral wall and overflowing
2Quantity of substance
If the liquid holding unit is moved to receive liquid, then liquid can be collected, but liquid flows toward the peripheral wall due to inertial force and may scatter
Solution Approach 1:
The protruding units are pre-positioned within the liquid accumulation unit to intercept liquid flow before it reaches the peripheral wall. This preliminary action of slowing and redirecting the liquid flow occurs automatically during movement and stopping, preventing scattering while enabling effective liquid collection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively suppresses liquid scattering and overflow by reducing the flow velocity and amount of liquid reaching the peripheral wall, ensuring efficient liquid collection and maintaining apparatus cleanliness.
Implementation Method 1
liquid that is held in the cap member tends to flow toward a direction that is opposite to the movement direction due to an inertial force
Implementation Method 2
if a cap member in which liquid is held is moved in a movement direction that intersects the direction of gravity, liquid that is held in the cap member tends to flow

AI summary
A liquid receiving device including a liquid holding unit that has a bottom unit and a peripheral wall unit that is installed in the bottom unit in a protruding manner, and in which the bottom unit and the peripheral wall unit form a liquid accumulation unit that is capable of accumulating a liquid. The liquid holding unit is capable of moving in a movement direction that intersects a direction of gravity, and has protruding units that protrude further upward than the bottom unit in a vertical direction in the liquid accumulation unit.
