Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid solvents are used in solid-phase reactions, then mixing and reaction efficiency is improved, but the ability to selectively accumulate and recover target metals is limited
Solution Approach 1:
The patent extracts and eliminates liquid solvents from the reaction system, performing solid-phase reactions in a completely liquid-free environment. This extraction of the harmful element (liquid solvent) enables both efficient solid-phase reactions and selective metal recovery through downstream processing without solvent interference.
Solution Approach 2:
The patent changes the physical state parameter from liquid-based to solid-based reaction medium. By transitioning from liquid solvent systems to solid-phase reactions with minimal liquid (less than 1 wt%), the system achieves both efficient mixing through high-viscosity mixers and selective metal accumulation through solid-phase reactions.
2Reliability
If liquid solvents are used to form metal halides, then reaction completeness is improved, but dependence on liquid solvents increases
Solution Approach 1:
The patent removes liquid solvents from the metal halide formation process, achieving complete reactions through solid-phase chemistry alone. The elimination of solvent dependency simplifies the system while maintaining reaction completeness through optimized solid-phase contact and heating conditions.
3Productivity
If high-viscosity mixers are used for solid powders, then mixing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent changes the mixing approach by using high-viscosity mixers that operate effectively in solid-phase conditions. This parameter change in mixer design enables efficient mixing of solid powders without requiring complex liquid-based mixing systems, achieving both good mixing efficiency and reasonable device complexity.
