Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of gas pressure is performed by skilled professionals, then analysis accuracy is maintained, but operator dependency increases and reproducibility decreases
Solution Approach 1:
The system performs automatic pressure adjustment and gas introduction without requiring skilled operators to manually adjust pressures. The control part autonomously manages the multi-position valve and pump based on analysis timing information, making the system self-sufficient and eliminating operator dependency while maintaining analysis accuracy.
Solution Approach 2:
The patent replaces manual mechanical pressure adjustment with an automated control system that uses electronic control to operate the multi-position valve and pump. This substitution of manual mechanical operations with automated mechanical-electronic control resolves the contradiction by maintaining precision while eliminating operator dependency.
2Reliability
If manual gas introduction is performed repeatedly, then analysis can be conducted, but productivity decreases due to time-consuming operations
Solution Approach 1:
The system automatically performs periodic gas introduction operations based on analysis timing information. The control part schedules and executes gas introduction from the sample bag and standard gas cylinder at appropriate intervals without manual intervention, maintaining reliable analysis capability while significantly improving productivity through automated periodic operation.
Solution Approach 2:
The automated system ensures continuous and uninterrupted gas introduction operations. The control part manages the sequence of introducing gas samples and standard gases without idle time or manual delays, maintaining analysis reliability while maximizing productivity through continuous automated operation.
3Ease of operation
If pressure variations occur during gas introduction, then operation simplicity is maintained, but analysis accuracy deteriorates
Solution Approach 1:
The system incorporates pressure sensing and control feedback mechanisms. The control part monitors and adjusts gas introduction pressure automatically based on real-time conditions, ensuring consistent pressure during analysis. This feedback control maintains analysis accuracy while preserving operational simplicity, as no manual pressure adjustment is needed.
Solution Approach 2:
The system automatically adjusts critical parameters such as gas introduction pressure and flow rate through the control part's management of the multi-position valve and pump. By dynamically changing these parameters under automated control, the system maintains constant pressure conditions for accurate mole fraction analysis while keeping the operation simple and operator-free.
