Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex manufacturing methods are used, then manufacturing precision can be improved, but productivity deteriorates
Solution Approach 1:
The manufacturing process is divided into distinct stages: material preparation, extrusion forming, and drying. This segmentation allows each stage to be optimized independently, improving overall efficiency while maintaining substrate integrity through controlled processing parameters at each step.
Solution Approach 2:
The patent employs parameter changes by controlling the extrusion temperature and moisture content during processing. By adjusting these parameters, the substrate maintains structural integrity while enabling efficient continuous production, resolving the contradiction between precision and productivity.
2Device complexity
If traditional manufacturing methods are used, then manufacturing complexity can be reduced, but substrate stability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-mixing materials with controlled moisture content and pre-heating the extrusion process. This ensures the substrate achieves stable structure and composition during manufacturing, preventing disintegration without requiring complex post-processing.
Solution Approach 2:
The patent replaces complex mechanical assembly processes with a continuous extrusion method. This substitution simplifies the manufacturing system while producing a stable, integrated substrate structure that resists disintegration during use.
3Ease of manufacture
If high moisture content materials are used, then ease of manufacture can be improved, but substrate reliability deteriorates
Solution Approach 1:
The patent controls the moisture content parameter within a specific range (5-20%) to balance manufacturability and reliability. This parameter optimization allows the material to be processed easily while ensuring the substrate maintains structural integrity and does not disintegrate during use.
Solution Approach 2:
The patent applies partial action by using a moderate moisture content level rather than high moisture content. This partial approach provides sufficient ease of manufacture while avoiding the negative effects of excessive moisture that would compromise substrate reliability and cause disintegration.
