Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-pressure synthesis or solvothermal methods are used to synthesize diamond particles, then diamond particles can be produced, but special techniques and expensive equipment are required, limiting productivity
Solution Approach 1:
The patent replaces expensive, complex synthesis equipment with simple, inexpensive glass containers (such as glass bottles or test tubes) that can be easily disposed of or reused. This substitution of cheap, simple containers for expensive, complex equipment directly resolves the contradiction by enabling high productivity through simplified device complexity.
Solution Approach 2:
The patent replaces mechanical high-pressure synthesis systems with a chemical solution-based approach. Instead of using complex mechanical pressure equipment, the invention uses chemical reactions in solution phase to synthesize diamond particles, thereby reducing device complexity while maintaining productivity.
2Ease of manufacture
If solvothermal method is used to synthesize diamond particles, then diamond particles can be produced, but the method requires reaction in supercritical or subcritical state in autoclave, requiring special techniques and expensive equipment
Solution Approach 1:
The patent replaces expensive autoclave equipment with simple glass containers that are inexpensive and easily obtainable. This substitution dramatically improves ease of manufacture by eliminating the need for specialized high-pressure autoclaves while maintaining the ability to synthesize diamond particles through solution-phase chemistry.
Solution Approach 2:
The patent changes the reaction parameters from supercritical or subcritical conditions requiring high pressure to ambient or mild temperature and pressure conditions. By modifying the reaction conditions to be less extreme, the invention eliminates the need for complex autoclave equipment and special techniques, thereby improving ease of manufacture.
3Productivity
If conventional synthesis methods are used, then diamond particles can be synthesized, but the process is performed in closed space using large equipment, reducing productivity
Solution Approach 1:
The patent segments the synthesis process into small-scale independent reactions in individual glass containers rather than requiring one large closed-space reactor. This segmentation allows multiple small reactions to proceed simultaneously, dramatically increasing productivity while reducing the volume of equipment needed for each individual reaction vessel.

AI summary
Diamond particles are generated in a solution by carrying out a step S1 of mixing an inorganic salt such as a metal halide, a metal oxyhalide, a metal nitrate, a metal phosphate and a metal sulfate into a solvent containing 10% by volume or more of an organic solvent such as an alcohol solvent, a ketone solvent, an ester solvent, an amide solvent, a hydrocarbon solvent, an aromatic solvent, a cellosolve solvent and a halogen solvent containing carbon atoms, to prepare a mixed solution, and then carrying out an aging step S2 of holding the mixed solution under an arbitrary temperature condition for a certain period of time.
