Liquid Receiving Apparatus Inclined Wall Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid receiving apparatuses, such as inkjet printer caps, face a challenge in efficiently discharging liquid without reducing the capacity to hold the liquid, due to the design of inclined inner surfaces which can limit the amount of liquid retained.
Innovation Solution
A liquid receiving apparatus with a discharging hole positioned next to an inclined wall, allowing liquid to flow against the wall and be discharged through the hole, while the wall's configuration, including a tapered surface and multiple inclined walls, enhances flow efficiency and reduces turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If an inclined inner surface is used in the liquid holder, then the liquid discharge speed is improved, but the liquid holding capacity is reduced
Solution Approach 1:
The patent introduces a new spatial dimension by positioning the discharge hole on the lateral wall rather than the bottom surface. This dimensional shift allows the liquid flow path to utilize the inclined wall surface while the discharge opening is located at a different spatial position, thereby maintaining both holding capacity and discharge efficiency
Solution Approach 2:
The liquid holder is segmented into distinct functional zones: the inclined wall surface for flow acceleration and the laterally positioned discharge hole for efficient ejection. This segmentation allows each component to optimize its function independently - the inclined surface maximizes flow velocity while the lateral discharge hole maximizes holding capacity
2Productivity
If the bottom portion is made inclined to discharge liquid, then the liquid discharge efficiency is improved, but the amount of liquid to be received is reduced
Solution Approach 1:
The discharge hole is repositioned from the bottom dimension to the lateral wall dimension. This allows the bottom surface to remain substantially flat for maximum liquid reception while the lateral discharge hole utilizes the inclined wall for efficient discharge, separating the reception and discharge functions in different spatial dimensions
Solution Approach 2:
Instead of inclining the bottom surface to achieve discharge (conventional approach), the patent inverts the approach by keeping the bottom flat for reception and creating the discharge pathway through the lateral wall using the inclined surface. This inversion resolves the contradiction between reception capacity and discharge efficiency
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
This configuration enables effective liquid discharge without reducing the liquid holding capacity, as the liquid flows efficiently along the inclined surfaces and through the discharging hole, improving the apparatus's ability to manage liquid without an inclined bottom portion.
Implementation Method 1
when the liquid holder is moved in the movement direction, the liquid in the liquid retaining section flows in a direction opposite to the movement direction on the bottom portion due to the inertial force

AI summary
A liquid receiving apparatus includes a liquid holder including a discharging hole for discharging liquid, a bottom portion in which the discharging hole is disposed, and a wall rising from the bottom portion and surrounding the discharging hole. The bottom portion and the wall define a liquid retaining section configured to retain the liquid. The liquid holder is configured to move in a first movement direction intersecting a gravity direction. The wall includes a first inclined wall oblique to the first movement direction. The discharging hole is positioned next to the first inclined wall.
