Engineering Contradiction Analysis
1Stability of the object's composition
If reference solutions are stored at temperatures different from operating temperature, then storage stability is improved, but the distribution of gas between phases becomes different from equilibrium distribution at operating temperature, requiring long term conditioning
Solution Approach 1:
The patent changes the physical state of the reference material from dissolved gas phase to trapped gas phase within a membrane structure. This parameter change allows the system to maintain equilibrium distribution without requiring prolonged conditioning, as the membrane physically constrains the gas phase and prevents compositional changes during storage and use.
Solution Approach 2:
The patent introduces a membrane as an intermediary element between the gas phase and liquid phase. This membrane acts as a barrier that maintains the trapped gas phase in equilibrium with the liquid phase, eliminating the need for long term conditioning while preserving storage stability.
2Measurement precision
If reference solutions are prepared immediately before use or kept at specific temperature, then compositional accuracy is maintained, but ease of operation is reduced due to impractical preparation requirements
Solution Approach 1:
The patent performs preliminary action by pre-establishing the equilibrium distribution of gas between phases during the manufacturing process. The reference solution is prepared and sealed with the membrane in advance, so that when deployed, it is immediately ready for use without requiring on-site preparation or temperature maintenance, thereby improving ease of operation while maintaining compositional accuracy.
Solution Approach 2:
The patent enables the reference solution to be self-sufficient by incorporating the membrane structure that automatically maintains equilibrium distribution. The system serves itself by physically constraining the gas phase and maintaining compositional stability without requiring external intervention, temperature control, or manual preparation, thus improving ease of operation.
3Measurement precision
If two compounds exist in equilibrium and are mutually convertible, then the reference solution can represent the parameter precisely, but temperature changes gradually change the chemical composition over time
Solution Approach 1:
The patent introduces a membrane as an intermediary that physically separates and constrains the gas phase, preventing temperature-induced compositional changes. The membrane maintains the equilibrium between mutually convertible compounds by isolating the gas phase, thereby preserving chemical composition stability while maintaining accurate parameter representation.
Solution Approach 2:
The patent changes the physical state and confinement of the gas phase by trapping it within the membrane structure. This parameter change prevents temperature-driven shifts in chemical equilibrium, maintaining stable composition over time while preserving the ability to represent the parameter precisely.
