Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If diamond abrasives are used for polishing ceramic, then polishing effectiveness is improved, but cost increases and scratches are produced
Solution Approach 1:
The patent changes the chemical parameter (pH) of the polishing composition to a specific range (6.0-9.0) to optimize the polishing process. This parameter adjustment allows the use of alternative abrasives like silica while maintaining effective polishing performance without the harmful scratching effects associated with diamond abrasives
Solution Approach 2:
The patent replaces expensive diamond abrasives with cheaper alternative abrasives such as silica or alumina. These alternative abrasives achieve the desired polishing effect at lower cost and without producing the harmful scratches that characterize diamond abrasive polishing
2Productivity
If diamond abrasives are used for polishing ceramic, then polishing effectiveness is improved, but cost increases
Solution Approach 1:
The patent substitutes costly diamond abrasives with economically viable alternatives such as silica or alumina abrasives. This replacement maintains sufficient polishing effectiveness for achieving mirror surfaces while dramatically reducing the cost of the polishing composition
Solution Approach 2:
By adjusting the pH parameter to 6.0-9.0 and controlling the zeta potential difference, the patent optimizes the performance of cheaper abrasive materials to match or exceed the effectiveness of diamond abrasives, thereby achieving cost-effective polishing
3Manufacturing precision
If high-grade mirror finishing is achieved, then surface quality is improved, but polishing cost increases
Solution Approach 1:
The patent establishes specific parameter ranges (pH 6.0-9.0, zeta potential difference 20-60 mV) that enable high-grade mirror finishing using cost-effective abrasive materials. These parameter optimizations allow achieving superior surface quality without incurring the high costs associated with diamond abrasive polishing
Solution Approach 2:
The patent employs inexpensive abrasive materials like silica or alumina that can achieve high-grade mirror surfaces when used under optimized conditions (controlled pH and zeta potential), replacing the need for expensive diamond abrasives
