Solution Overview

Problem

Existing bottle and cap assemblies for selectively dispensing one beverage into another are often unreliable and complex, with high manufacturing costs.

Innovation Solution

A beverage container and cap assembly featuring a base member with a fluid flow channel, a reservoir member with a piercing member, and a cap structure that can be selectively depressed to allow the first beverage or powder to flow into a second beverage, utilizing a deformable surface and a sharped conical tip to pierce the reservoir, with an optional bladder member for fluid direction and a rotatable cap configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional bottle and cap assemblies are used for selectively dispensing one beverage into another, then the dispensing function is provided, but the system becomes unreliable and complex with high manufacturing costs

Engineering Contradiction:

Improvedispensing reliabilityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cap assembly is divided into distinct functional components: a cap body, a reservoir member with deformable surface, a piercing member, and a fluid flow channel. Each component performs a specific function, allowing for simplified manufacturing and assembly while improving reliability through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The piercing member is pre-positioned within the reservoir member in a retracted state before use. When the cap is twisted, the piercing member automatically pierces the deformable surface to establish fluid communication, eliminating the need for complex activation mechanisms and improving reliability

Inventive Principle:

Principle #10Preliminary action

2Reliability

If conventional bottle and cap assemblies are used for selectively dispensing one beverage into another, then the dispensing function is provided, but manufacturing costs become high

Engineering Contradiction:

Improvedispensing reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The reservoir member employs a deformable surface made from flexible material that can be easily pierced and deformed. This simple flexible membrane replaces complex valve mechanisms, significantly reducing manufacturing costs while maintaining reliable dispensing function

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

Instead of using a complex mechanism to open a pre-formed hole, the invention inverts the approach by having the piercing member create the opening through direct piercing action when the cap is twisted, simplifying the overall mechanism and reducing manufacturing complexity

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If a piercing member with deformable surface is used to allow beverage flow, then selective dispensing is achieved, but the structure becomes more complex

Engineering Contradiction:

Improveselective dispensing operationVSAvoidcap structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The piercing member, deformable surface, and fluid flow channel are integrated into a unified cap assembly structure where components work together seamlessly. The piercing member is positioned within the reservoir member, and the fluid flow channel connects the reservoir to the cap outlet, creating a compact integrated design that improves ease of operation without proportionally increasing complexity

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A beverage container and cap assembly for selectively dispensing a first beverage or a powder into a second beverage, including: a beverage container and a cap assembly, wherein the cap assembly includes: a base member; a reservoir member; wherein the reservoir member includes a piercing member disposed therein having a first end that is coupled to a deformable first surface of the reservoir member and a second piercing end that is disposed adjacent to an opposed pierceable second surface of the reservoir member; and a cap structure disposed partially within the base member that is configured to be selectively depressed, thereby contacting the first end of the piercing member and biasing the second piercing end of the piercing member through the opposed pierceable second surface of the reservoir member, thereby allowing the first beverage or the powder to flow from the reservoir member into the beverage container.
