Solution Overview

Problem

Existing portable liquid carrying containers, such as water bottles and beverage pouches, are difficult for active military personnel to use with one hand, especially in combat situations, due to their rigidity, noise, reflectivity, and requirement for two-handed operation, and they are cumbersome when used with protective face masks.

Innovation Solution

A flexible, non-reflective liquid carrying container designed to fit into military gear pockets or ammunition holders, with a one-handed closure mechanism and an adapter for face masks, allowing easy access and use without distracting from other tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If water bottles and canteens are made rigid to maintain structure, then they can hold liquid effectively, but they become difficult to carry and access with one hand

Engineering Contradiction:

Improvestructural stabilityVSAvoidone-handed accessibility

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent employs a flexible pouch made of laminate material that can be easily carried and accessed with one hand, while still maintaining its ability to hold liquid effectively. The flexible nature allows it to conform to hand movements and be quickly removed from pouches or pockets without requiring two hands for manipulation.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of operation

If beverage pouches are made flexible for easy handling, then they are easier to carry, but they create unwanted noise when squeezed or moved

Engineering Contradiction:

Improveease of carryingVSAvoidnoise

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent uses a composite laminate material consisting of multiple layers including a noise-reducing inner layer. This composite structure provides both the flexibility needed for easy handling and the noise-dampening properties to prevent crinkling sounds during movement or squeezing, directly addressing the contradiction between ease of carrying and noise generation.

Inventive Principle:

Principle #40Composite materials

3Reliability

If traditional closures are used on water bottles, then they can seal liquid effectively, but they require two hands to open and close

Engineering Contradiction:

Improveliquid sealingVSAvoidclosure operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical two-handed closure systems with a one-handed operable closure mechanism. The closure includes a spout that can be opened and closed using thumb pressure or a simple lever action that requires only one hand, while still maintaining effective liquid sealing through its design features.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Strength

If canteens are made rigid for durability, then they can withstand rough handling, but they must be held above the mouth to drink and interfere with other duties

Engineering Contradiction:

ImprovedurabilityVSAvoiddrinking convenience

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent uses a flexible pouch construction that eliminates the need for rigid canteen structures. The flexible material allows the container to be held at any position including at mouth level for drinking, and can be easily manipulated with one hand. The laminate material provides sufficient durability and protection while enabling much greater operational convenience compared to traditional rigid canteens.

Inventive Principle:

Principle #30Flexible shells and thin films

5Volume of moving object

If beverage pouches are made small for portability, then they fit in pockets better, but they have limited liquid capacity

Engineering Contradiction:

Improvecontainer sizeVSAvoidliquid capacity

Core Design Contradiction:

Volume of moving objectVSQuantity of substance

Solution Approach 1:

The patent designs the flexible pouch to nest compactly within standard military pouches or pockets when not in use, yet expands to provide adequate liquid capacity when filled. The flexible laminate material allows the pouch to be compressed to a small size for portability while maintaining the ability to hold sufficient liquid volume when deployed.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A liquid carrying container particularly suited for military use can be sized and configured to easily fit into the pockets or pouches of military uniforms, tactical gear, and other gear, such as flight suits, or into an ammunition magazine holder, which are specifically provided for holding equipment and supplies which require easy one handed access. The container is substantially shape retaining and has a bottom edge. The container includes a container closure having a push-pull element and a protective over cap. The closure maintains a fixed position with respect to the container so when retrieved by a user with one hand always opens in the same direction without the user needing to see the retrieved container. The container can supply liquid to a tube extending from a face mask using an adapter that connects a face mask tube valve to the push-pull element of the container closure.
