Solution Overview

Problem

Existing bubbling devices for creating sparkling water require complex sensor systems and multiple settings to achieve a presettable bubbling level, which is inefficient and costly.

Innovation Solution

A bubbling device with a controllable valve and weight-determining mechanism using a force transducer or scale to adjust gas flow based on the weight of the CO2 gas bottle, allowing for user-adjustable bubbling levels and automatic reordering when the gas is low, with optional RFID or optical identification for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sensors and complex control systems are used to achieve preset carbonation levels, then carbonation precision is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent extracts the essential measurement function from complex sensor systems and implements it through a simple weight determination device. By measuring only the weight of the gas cylinder, the system achieves sufficient control for home use without requiring multiple sensors, pressure transducers, or complex flow meters that would increase device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a low-cost weight determination device instead of expensive industrial-grade sensors. This simplified measurement approach is sufficient for the intended application scope (home carbonation), thereby reducing device complexity while maintaining adequate measurement precision for consumer needs.

Inventive Principle:
