Combustion Device Gas Usage Measurement with Temperature Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combustion devices fail to accurately measure and inform users about the amount of used gas, as they do not account for air or gas temperature variations, leading to inaccurate calculations and lack of information on gas usage across different operation modes.
Innovation Solution
A combustion device equipped with a burner, blower, gas valves, gas temperature sensors, and a control unit that calculates the first amount of used gas based on user input and compensates it with measured temperature data to provide an accurate second amount of used gas, which is then displayed to the user, allowing for precise gas usage tracking across heating and hot water modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gas temperature is not compensated in the calculation, then the calculation process is simple, but the measurement precision of gas usage amount is inaccurate
Solution Approach 1:
The patent applies parameter changes by introducing temperature compensation into the gas usage calculation. The control unit measures gas temperature and uses it to adjust the calculated gas usage amount, transforming the calculation from a simple volume-based measurement to a temperature-compensated measurement that reflects actual gas consumption more accurately.
2Loss of information
If only basic gas usage calculation is performed, then the device complexity is low, but the information provided to user is insufficient
Solution Approach 1:
The patent implements feedback by providing compensated gas usage information back to the user through a display interface. The control unit calculates temperature-compensated gas usage amounts and presents this corrected information to the user, enabling them to understand actual gas consumption patterns and make informed decisions about energy usage.
