Innovation Solution
A portable gas-monitoring device equipped with a computing component, emission-detecting component, and location-detecting component that allows for real-time sampling and data logging of methane emissions, associating geographic locations with emission data and transmitting this information to external devices for compliance and regulatory purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data recording methods are used, then device complexity is reduced, but measurement precision and reliability deteriorate due to human errors
Solution Approach 1:
The monitoring device automatically records and logs emission data with location information without requiring manual transcription. The system self-documented measurements by integrating GPS location tracking with emission detection, eliminating human operators from the data recording process and thereby preventing transcription errors while maintaining data accuracy.
Solution Approach 2:
The patent replaces manual mechanical recording processes with electronic automated systems. The emission detection device communicates wirelessly with the location detection device, and data is automatically stored in electronic format, substituting the mechanical act of manual writing and transcription with automated electronic data capture and storage.
2Productivity
If real-time monitoring is implemented, then productivity is improved, but loss of time for data processing and compliance assessment worsens
Solution Approach 1:
The system provides real-time feedback by continuously monitoring emissions and immediately associating data with location information. The automated wireless communication between detection devices and central processing enables immediate data availability, allowing compliance assessments to be performed in real-time rather than requiring batch processing of manually collected data.
Solution Approach 2:
The system performs preliminary data processing and location association automatically as measurements are taken. By pre-processing data in the field and storing it in organized formats with embedded location metadata, the system eliminates the need for time-consuming post-fieldwork data consolidation and preparation activities.
3Ease of operation
If portable monitoring devices are used, then ease of operation is improved, but measurement precision may worsen due to movement and environmental factors
Solution Approach 1:
The system is designed to function dynamically during movement rather than requiring static positioning. The portable device captures emissions data continuously as it moves through the landfill, with location information recorded at each measurement point. This dynamic approach allows field deployability while maintaining precision through automated location-tagging of each measurement.
