Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If fine particles are used to form porous medium, then porosity is improved, but dispersion stability deteriorates
Solution Approach 1:
The invention changes the physical state of the porous medium from solid particles to a liquid composition containing polymerizable compounds. This parameter change allows the porous structure to be formed through phase separation during polymerization rather than relying on particle dispersion, thereby improving both porosity and dispersion stability simultaneously
Solution Approach 2:
The invention utilizes phase transition during polymerization where the polymerizable compound transitions from a homogeneous liquid state to a separated phase, creating porosity. This phase transition mechanism replaces the need for particle dispersion while achieving the desired porous structure with inherent stability
2Ease of manufacture
If polymerizable compound and solvent are mixed, then ease of manufacture is improved, but compatibility deteriorates
Solution Approach 1:
The invention performs preliminary action by selecting specific polymerizable compounds and solvents that are pre-determined to be compatible based on their chemical structure characteristics. This preliminary selection ensures both ease of manufacture through simple mixing and maintenance of compatibility, avoiding phase separation before polymerization
Solution Approach 2:
The invention changes the chemical parameters of the polymerizable compound and solvent to achieve optimal compatibility. By adjusting molecular structure parameters and chemical composition, the system achieves both easy manufacturability and stable compatibility throughout the process
3Stability of the object's composition
If material selection is restricted, then compatibility is improved, but adaptability deteriorates
Solution Approach 1:
The invention establishes universal selection criteria based on chemical structure characteristics that can be applied to various polymerizable compounds and solvents. This universal approach allows the system to maintain compatibility while being adaptable to different materials and applications, expanding versatility without sacrificing stability
