Multi-Directional Liquid Drawing Unit for Tilted Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid product containers struggle to efficiently draw and spray liquid when the container is tilted or placed horizontally, leading to residual liquid and inconvenience in use.
Innovation Solution
The liquid product container features an extending drawing unit with multiple extending liquid drawing openings arranged annularly on the main body, which connects to the liquid dip tube, allowing it to draw liquid in multiple directions from the bottom of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid dip tube extends curvedly with the drawing end opening toward a same direction as the spray nozzle, then the liquid product can be drawn effectively when the container is placed upright, but the actuator cannot spray out the liquid product when the container is placed horizontally or with the actuator leaning back
Solution Approach 1:
The drawing end opening is segmented into multiple openings (first, second, third, and fourth openings) arranged in different directions. This segmentation allows the liquid dip tube to draw liquid from multiple orientations simultaneously, ensuring that at least one opening remains submerged regardless of container position, thus resolving the contradiction between reliable spray function and adaptability to different positions.
Solution Approach 2:
The invention transitions from a single-direction drawing opening to a multi-directional arrangement by positioning openings at different angular positions (0°, 90°, 180°, 270°) around the container's bottom circumference. This dimensional expansion in the horizontal plane enables the system to maintain liquid contact across various container orientations, solving the position-dependent spray failure.
2Loss of substance
If the drawing end opening is located at the bottom corner of the container body, then liquid product waste is prevented when upright, but residual liquid remains when the container is tilted or placed horizontally
Solution Approach 1:
The single bottom corner opening is segmented into four separate openings distributed around the bottom circumference at different angular positions. This segmentation ensures comprehensive coverage of the liquid volume regardless of container tilt angle, preventing both waste and residual liquid by maintaining multiple potential liquid contact points.
Solution Approach 2:
Instead of using a single opening that might miss liquid in certain positions, the invention employs four openings that provide excessive coverage capability. This partial redundancy ensures that even if some openings are not optimally positioned relative to the liquid level, others will effectively draw liquid, eliminating residual liquid while preventing waste.
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 ensures that even when the container is tilted or placed horizontally, at least one extending liquid drawing opening remains submerged, allowing the liquid dip tube to draw liquid effectively and the actuator to spray it correctly and smoothly.
Implementation Method 1
The extending liquid drawing passages respectively form multiple extending liquid drawing openings on an annular side surface of the main body
Implementation Method 2
The liquid dip tube is connected to the extending liquid drawing passages, such that the liquid dip tube is connected to the extending liquid drawing openings
