Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If external calibrant traps are used for detector calibration, then calibration can be performed, but the process becomes labor-intensive, costly, and difficult to automate
Solution Approach 1:
The system uses an internal calibrant chamber that automatically introduces calibrant to the detector without requiring external traps or manual intervention. The calibrant is stored internally and delivered through automated control, making the calibration process self-service and eliminating labor-intensive external trap handling.
Solution Approach 2:
The invention extracts the calibrant storage and delivery function from external traps and integrates it directly into the detector system through an internal calibrant chamber. This separation of the calibrant management function from external components enables automation while reducing operational complexity.
2Duration of action of stationary object
If external calibrant traps are used, then calibration is possible, but the traps have limited lifetimes and require frequent replacement and refilling
Solution Approach 1:
The invention merges the calibrant storage chamber with the detector system, creating an integrated internal calibrant chamber. This combination eliminates the need for separate external traps that require replacement, as the internal chamber is permanently integrated and can be refilled or maintained in place.
Solution Approach 2:
The system performs preliminary preparation by storing calibrant in an internal chamber that is pre-configured for automated delivery. This preliminary setup eliminates the need for frequent external trap replacements and refillings, as the calibrant is already positioned and ready for automated introduction.
3Reliability
If external traps are used for calibration, verification, and sensitivity checks, then these functions can be performed, but contamination risks increase and costs increase
Solution Approach 1:
The invention extracts the calibrant, verification substance, and sensitivity substance from external sources and stores them in dedicated internal chambers. This extraction eliminates the risk of contamination from external trap handling and installation, while maintaining calibration accuracy through controlled internal delivery.
Solution Approach 2:
The internal chambers act as intermediaries between the stored substances and the detector. This intermediary structure provides a controlled environment for substance delivery, preventing direct exposure to external contamination sources while ensuring accurate and reliable calibration, verification, and sensitivity checks.
