Sparkling Water Gas Inflow Resetting via Mechanical Pressure Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sparkling water machines experience instability and false detection due to electric control systems, leading to poor performance in stopping carbon dioxide gas inflow into sparkling water bottles.
Innovation Solution
A mechanical structure is employed to control gas inflow and resetting, featuring a gas inflow pressure rod, gas path main body, gas pressure valve body, and gas inflow connecting rod hook, which rely on mechanical feedback to stop gas inflow when a specified pressure is reached, eliminating the need for electric control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electric control portion is used to detect gas pressure and stop gas inflow, then the gas filling process can be controlled, but the stability deteriorates and false detection occurs
Solution Approach 1:
The patent replaces the electric control portion with a purely mechanical control system. The gas pressure valve body, gas pressure spring, and connecting rod mechanism form a mechanical feedback system that automatically stops gas inflow when the specified pressure is reached, eliminating the instability and false detection issues associated with electric sensors while maintaining automatic control functionality.
2Reliability
If a mechanical structure is used to control gas inflow, then stability and reliability improve, but the device complexity increases
Solution Approach 1:
The mechanical control system is designed to be self-regulating through the gas pressure spring and connecting rod mechanism. When the gas pressure reaches the specified value, the gas pressure valve body automatically moves to close the gas passage without requiring external control signals or complex control logic, thereby improving reliability while keeping the structure relatively simple.
Solution Approach 2:
The patent implements a mechanical feedback mechanism where the gas pressure spring senses the gas pressure in the water bottle and automatically adjusts the gas pressure valve body position. This feedback loop ensures stable and reliable gas inflow control by continuously monitoring pressure and adjusting the valve accordingly, without adding significant complexity to the overall system.
