Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reagent vapor or infiltrating material vapor enters the air system, then the air system becomes blocked and cross-contaminated, but adding trap bottles increases device complexity
Solution Approach 1:
The patent introduces trap bottles as intermediary components between the retorts and the pressure generating assembly. These trap bottles serve as mediating elements that capture and condense reagent vapors before they can enter the air system, thus protecting the air system from blockages and cross-contamination while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent extracts the harmful reagent vapors from the air system by introducing separate trap bottles that specifically target and remove these vapors. This extraction approach isolates the vapor capture function from the main air system, preventing cross-contamination while adding minimal complexity to the overall device.
2Object-affected harmful factors
If trap bottles are added to condense vapor, then cross-contamination is prevented, but the device structure becomes more complex
Solution Approach 1:
The trap bottles act as intermediary components that specifically address the cross-contamination issue. By placing these trap bottles at strategic locations in the fluid paths, the patent creates isolated zones for vapor condensation that prevent harmful factors from affecting the main system without requiring a complete redesign of the entire device structure.
Solution Approach 2:
The patent segments the fluid handling system by introducing separate trap bottles for different retorts (first trap bottle for first retort, second trap bottle for second retort). This segmentation allows each trap bottle to independently handle vapor condensation for its respective retort, preventing cross-contamination while maintaining a modular and manageable structure.
3Reliability
If multiple trap bottles are used for multiple retorts, then vapor condensation is improved, but device complexity increases
Solution Approach 1:
The patent divides the vapor condensation system into separate segments - a first trap bottle for the first retort and a second trap bottle for the second retort. This segmentation ensures that vapor condensation occurs independently for each retort, improving overall effectiveness while maintaining a modular structure that is easier to maintain and operate compared to a single complex condensation system.
Solution Approach 2:
The trap bottles are positioned in the fluid paths before the vapors can enter the air system or mix with other reagents. This preliminary condensation action prevents cross-contamination and blockages before they occur, ensuring high reliability of vapor management without requiring complex real-time monitoring or intervention systems.
