Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing beverage bottles, such as PET bottles, fail to effectively keep carbonated beverages from going flat, as sealing the bottle with a shrunken bellows section allows carbon dioxide to be released, and conventional devices for preventing CO2 divergence are inconvenient to carry and use outside the home.

Innovation Solution

A beverage bottle with a volume-reducing structure and a shrunken state-maintaining mechanism, such as helical protrusions and recesses or bellows-shaped sections with engageable hooks, that allows the bottle to be sealed and maintained in a reduced volume state, reducing air contact and preventing flatness without the need for additional instruments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the bottle is sealed with a shrunken bellows section, then the bottle appears to maintain the leftover beverage, but carbon dioxide is released freely causing the beverage to go flat

Engineering Contradiction:

Improveability to keep carbonated beverage from going flatVSAvoidcarbon dioxide release

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

A CO2 divergence preventing device is introduced as an intermediary component between the beverage and the external environment. This device includes a holding plate with a through hole that restricts CO2 escape, allowing the beverage to remain carbonated while still permitting liquid ventilation if needed.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a controlled environment within the bottle by preventing CO2 escape, effectively maintaining an inert carbonated atmosphere around the leftover beverage. This protects the beverage from oxidation and flavor degradation that would occur with direct air contact.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

2Reliability

If a carbon dioxide divergence preventing device is used, then the leftover carbonated beverage is kept from going flat, but the device is inconvenient to carry and use outside the home

Engineering Contradiction:

Improveability to keep carbonated beverage from going flatVSAvoidconvenience of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The CO2 divergence preventing device is merged with the bottle structure itself, integrating the function into the cap or bottle body. This eliminates the need for separate carrying devices while maintaining the CO2 prevention function, making it convenient for use anywhere.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bottle structure itself provides the CO2 prevention function through integrated features such as a cap with controlled opening or built-in valve mechanism, allowing the bottle to serve its own preservation needs without external devices.

Inventive Principle:

Principle #25Self-service

3Reliability

If the bottle volume is reduced to maintain the shrunken state, then air contact is reduced, but the bottle structure becomes more complex

Engineering Contradiction:

Improveability to reduce air contact with beverageVSAvoidbottle structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bottle incorporates a flexible trunk section with bellows-like structure that can be compressed and maintained in a shrunken state. This flexible membrane structure allows volume reduction without requiring complex rigid mechanisms, simply needing the cap to seal and maintain pressure.

Inventive Principle:

Principle #30Flexible shells and thin films
