Solution Overview

Problem

Existing carbonators for domestic use do not adequately protect users from glass fragments in the event of a bursting beverage bottle, and previous solutions have been either ineffective or involve complex, bulky, and costly designs.

Innovation Solution

A carbonator design featuring a beverage container compartment with a form-fit connection between two portions, utilizing grooves and a retaining ring to securely mount the second portion rotatably, thereby providing a safe and secure enclosure that can tolerate high separating forces in case of a bottle burst.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a complex protective enclosure is used to protect users from glass fragments, then user safety is improved, but device complexity and cost increase

Engineering Contradiction:
Improveprotection from glass fragmentsVSAvoidenclosure design complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The beverage container compartment is divided into two portions: a first portion forming the compartment body and a second portion forming a protective door that can rotate independently. This segmentation allows the protective function to be isolated to the second portion while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second portion is designed to rotate relative to the first portion, transitioning between an open position (allowing bottle insertion/removal) and a closed position (providing protection). This dynamic element replaces complex locking mechanisms with a simple rotational movement that provides safety only when needed.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a secure form-fit connection is used to tolerate high separating forces, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection strength under burst pressureVSAvoidconnection structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The grooves and retaining ring are integrated directly into the first and second portions, eliminating the need for separate fastening components. The retaining ring engages with grooves in both portions to create a unified form-fit connection that tolerates high separating forces while maintaining structural simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The grooves are designed with curved cross-sections that match the retaining ring geometry, creating a form-fit connection that distributes stress evenly around the circumference. This curved geometry provides superior force distribution compared to linear fastening elements.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of operation

If a rotatable second portion is used to provide both access and protection, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvebottle access and compartment closureVSAvoidgroove and retaining ring alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The grooves and retaining ring are designed to self-align during assembly. The retaining ring's geometry naturally guides it into the correct position within the grooves, eliminating the need for complex alignment procedures or precision machining tolerances.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The retaining ring has a cross-section slightly larger than the groove cross-section, creating an interference fit that provides both secure retention and smooth rotational movement. This parameter optimization balances manufacturing tolerances with operational performance.

Inventive Principle:
Principle #35Parameter changes
