Solution Overview

Problem

Flexible hydration containers often experience kinking of drink tubes when packed, leading to fluid leakage due to difficulties in accessing and properly installing the detachable coupling, which can result in incomplete separation from backpacks.

Innovation Solution

A liquid-dispensing apparatus featuring a flexible and translucent container with a channel component and detachable coupling element that allows for fluid communication, preventing complete wall contact and ensuring complete liquid discharge through a T-shaped channel design, which is rotatable and easy to clean, reducing air bubbles and bacterial harborage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the drink tube is loosely bundled to manage extra length, then the tube can be stored compactly, but the tube becomes kinked which closes off the ability to ingest fluid

Engineering Contradiction:
Improvestorage compactnessVSAvoidfluid ingestion capability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The channel component is designed to be flexible and dynamic, allowing it to adapt its shape as the container collapses during fluid extraction. The channel maintains fluid flow capability throughout the collapse process, transforming from a rigid structure to a flexible one that moves with the container walls.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The channel component is divided into multiple sections including a collapsed portion, a terminal end, and connection portions. This segmentation allows different parts of the channel to perform different functions: the collapsed portion prevents wall contact while the terminal end maintains fluid communication with the coupling element.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If a detachable coupling element is used between tubing and container, then the coupling can be detached for cleaning or replacement, but it is difficult to access and sometimes not properly installed causing fluid leakage

Engineering Contradiction:
Improvecoupling detachabilityVSAvoidcoupling installation accessibility
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The channel component is designed to guide the coupling element into proper installation automatically. The tapered portion and channel geometry work together to ensure the coupling is properly seated without requiring complex installation procedures or tools, making the system self-guiding during assembly.

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If the container walls are allowed to collapse completely during fluid extraction, then the container can be compactly stored, but the drink tube becomes kinked preventing fluid flow

Engineering Contradiction:
Improvecontainer compactnessVSAvoidfluid extraction efficiency
Core Design Contradiction:
Volume of moving objectVSProductivity

Solution Approach 1:

The channel component is designed in advance to prevent the harmful effect of wall contact before it can occur. The raised portion and collapsed portion are positioned to create a physical barrier that stops the container walls from sealing together, thereby preventing tube kinking before it can happen during the collapse process.

Inventive Principle:
Principle #9Preliminary anti-action

4Productivity

If the channel component prevents complete wall contact during collapse, then fluid flow is maintained, but the channel design becomes more complex

Engineering Contradiction:
Improvefluid extraction efficiencyVSAvoidchannel structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The channel component merges multiple functions into a single integrated structure: it prevents wall contact, guides fluid flow, maintains tube positioning, and enables complete container collapse. This consolidation reduces the number of separate components needed while achieving multiple objectives simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A liquid-dispensing apparatus includes a flexible container having first and second opposing walls and a bottom surface. The walls and bottom surface define an interior chamber configured to contain liquid. A coupling element is coupled to the first opposing wall and provides fluid communication between the chamber and the exterior of the container. A channel component is disposed within the chamber and has a length. The channel component has a proximal end in fluid communication with the coupling element and a terminal end extending toward the bottom surface of the container. The channel component is configured such that liquid may pass through the entirety of the length.
