Dual-Compartment Gas Collection for Accurate Volume Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas measuring apparatuses suffer from inaccurate measurements due to gas leakage during collection, as the single cavity design leads to repeated lifting and falling, causing delays in capturing the gas and reducing measurement accuracy.
Innovation Solution
A gas measuring apparatus with two symmetrically arranged gas entrapping compartments and a rotatable gas collecting device that rotates under buoyancy, ensuring continuous gas accumulation and release without leakage, using positioning holders to limit rotation angle and adjust collision points for precise measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cavity structure is used for gas collection, then the device complexity is reduced, but the measurement precision deteriorates due to gas leakage during the lifting and falling cycle
Solution Approach 1:
The gas collecting device is divided into a first gas collecting cavity and a second gas collecting cavity that work alternately. While one cavity is collecting gas, the other is discharging, eliminating the gas leakage problem of single-cavity designs and achieving continuous measurement without increasing overall system complexity
2Productivity
If the gas collecting device is lifted and fallen repeatedly in a single cavity, then the gas can be collected and discharged, but the productivity deteriorates due to time loss during the lifting-falling cycle causing gas leakage
Solution Approach 1:
The dual-cavity design enables continuous gas collection by having one cavity collect gas while the other discharges simultaneously. This eliminates idle time between collection cycles, as the switching between cavities is continuous and seamless, maintaining constant productivity without time loss
3Measurement precision
If positioning holders are added to limit rotation angle, then the measurement precision is improved through controlled rotation, but the device complexity increases
Solution Approach 1:
Positioning holders are added only at specific critical locations where rotation angle control is needed, rather than throughout the entire device. This localized approach provides precise rotation control for measurement while minimizing the increase in overall device complexity

Function Achieved in This Case
The apparatus improves measurement accuracy by preventing gas leakage and ensuring precise volume collection through controlled rotation and symmetrical compartment design, enhancing the reliability of gas volume calculations.
Implementation Method 1
the gas collecting device rotates under the buoyancy effect of the bubbles which are accumulated
Implementation Method 2
bubbles emerge from the gas inlet and rise into one of the two gas entrapping compartments
Implementation Method 3
as the bubbles accumulate, the liquid medium in the one of the two gas entrapping compartments is gradually discharged
