Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing need for accurate and reliable breathing air and gas purity monitoring systems that ensure the quality and safety of breathing air produced by air compressors, requiring on-site analysis by an independent, certified laboratory to meet governmental and safety agency requirements, while ensuring data security and minimizing unauthorized access.
Innovation Solution
A laboratory-on-location gas sample test system that includes a swappable 'canary' gas sensor module for accurate calibration, redundant sensors for increased reliability, and a communication device for transmitting data to a remote accredited laboratory for analysis, with a cloud-based portal for continuous monitoring and accreditation, and the capability to detect dangerous impurities and shut down the air compressor if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gas sensors are accessed by unauthorized personnel for calibration or adjustment, then ease of operation is improved, but measurement precision deteriorates due to potential tampering or disturbance
Solution Approach 1:
The system divides sensor access into two segments: unauthorized personnel can only access the sealed housing externally, while authorized calibration is performed through a separate, controlled interface that requires authentication. This segmentation maintains measurement precision while enabling legitimate operational adjustments.
Solution Approach 2:
A microprocessor-controlled interface acts as an intermediary between personnel and the gas sensors. This intermediary verifies authorization credentials before allowing calibration operations, preventing unauthorized tampering while enabling legitimate access for maintenance and calibration activities.
2Measurement precision
If a secure housing is used to protect gas sensors from unauthorized access, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The security housing, sensor mounting structure, and calibration interface are merged into a single integrated unit. This consolidation protects the sensors while providing a unified access mechanism that reduces overall system complexity compared to separate security and calibration components.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides physical protection for the sensors, contains the calibration interface, and implements access control. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity while maintaining security and precision.
3Reliability
If continuous monitoring is implemented to detect dangerous impurities, then reliability is improved, but use of energy increases
Solution Approach 1:
The system implements periodic sampling and analysis of gas impurities rather than truly continuous monitoring. The microprocessor controls the sensors to take measurements at predetermined intervals, which maintains reliable safety detection while significantly reducing power consumption compared to constant monitoring.
Solution Approach 2:
The system uses feedback control where the microprocessor monitors sensor readings and only activates full monitoring modes when impurity levels approach threshold values. During normal safe conditions, monitoring operates in a lower-power standby mode, maintaining reliability while minimizing energy usage.

AI summary
A breathing air laboratory on location gas sample test and data collecting system and method, at a remote breathing air provider's facility, that includes an air compressor, for remotely testing, collecting, and monitoring the quality and purity of the breathing air being produced at the provider's facility, that allows an accredited independent monitoring, testing, and analyzing facility to provide breathing air validation and certification to a cloud-based air quality test and analysis account belonging to the breathing air provider facility at any time. The system includes redundant gas sample air sensors for O2 and CO to ensure quality and accuracy in the breathing air test and data collection, and analysis and a “canary” gas sample test module securely mounted in a laboratory chassis, but manually swappable, to ensure credibility and accuracy of the sensors being used to test gas/air samples.
