Bottle Fluid Flow Controller with Segmented Air and Liquid Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle designs experience irregular and uneven fluid flow when inverted due to air interference, leading to leakage and gurgling, as prior solutions fail to effectively combine a reservoir in the neck with a side-located air inlet hole that can be pointed in any direction without leakage.
Innovation Solution
A mechanism featuring a reservoir attached to the bottle neck with a vertical tube allowing air to enter from the side, preventing liquid leakage by blocking the air inlet with an extension, and a horizontal tube ensuring smooth fluid flow regardless of the air inlet direction, using a cap system to manage air flow and fluid discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air inlet hole is placed in the side of the bottle neck, then air can enter the bottle to enable fluid flow, but liquid leakage occurs when the bottle is inverted
Solution Approach 1:
The air inlet system is segmented into two separate components: a vertical tube for air entry and a horizontal tube for fluid discharge. This segmentation allows independent optimization of each function - the vertical tube enables air to enter from any orientation while the horizontal tube maintains proper fluid flow path, eliminating the leakage problem that occurred when a single side-located air inlet had to serve both functions.
Solution Approach 2:
The vertical tube acts as an intermediary element between the external environment and the bottle interior. It provides a dedicated air passage that does not directly connect to the fluid discharge path, thereby mediating the air entry function without compromising liquid containment. The extension blocking the lower end of the vertical tube further ensures that this intermediary structure prevents leakage while maintaining air flow.
2Reliability
If air inlet hole is pointed upward to prevent leakage, then liquid containment is maintained, but smooth fluid flow cannot be achieved in all orientations
Solution Approach 1:
The vertical tube is designed to perform multiple functions: it serves as the air inlet passage and simultaneously allows the bottle to be used in any orientation without leakage. The extension blocking its lower end provides universal orientation capability, while the upper opening maintains the air entry function. This multi-functionality resolves the contradiction between containment reliability and orientation adaptability.
Solution Approach 2:
Instead of pointing the air inlet hole upward as in conventional designs, the invention inverts the approach by using a vertical tube with the opening at the top and a blocking extension at the bottom. This inverted structure allows air to enter from any bottle orientation while preventing liquid leakage, thereby achieving both containment reliability and orientation flexibility.
3Device complexity
If conventional bottle design is used, then structure is simple, but fluid flow is irregular and uneven when inverted
Solution Approach 1:
The flow control system is segmented into distinct vertical and horizontal tube components, each with specific functions. This segmentation creates separate pathways for air entry and fluid discharge, eliminating the irregular flow and gurgling that occur in conventional single-opening designs. The structural complexity increase is minimal while achieving smooth, continuous fluid flow.
Solution Approach 2:
The vertical tube with blocking extension is installed in advance to establish proper air entry pathways before fluid discharge begins. This preliminary configuration ensures that air can continuously enter the bottle through the vertical tube while fluid flows smoothly through the horizontal tube, preventing the irregular flow patterns that occur when air and fluid paths are not pre-established.

Implementation Method 1
a vertical tube (9) that has a bottom end (502) with a bottom opening (503) and a top end (504) with a top opening (505)... enables air to flow from the reservoir to the bottle through the vertical tube
