Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat-drying treatment is applied to RG-I pectin, then drying cost and simplicity are improved, but solubility deteriorates due to thermal aggregation
Solution Approach 1:
The patent applies preliminary action by co-mixing RG-I pectin with negatively charged polysaccharides before heat-drying treatment. This pre-mixing step creates a protective environment that prevents thermal aggregation during the subsequent drying process, thereby maintaining solubility while still benefiting from the simple heat-drying method
Solution Approach 2:
The patent uses negatively charged polysaccharides as intermediary substances that mediate between RG-I pectin chains during heat-drying. These polysaccharides act as spatial separators and electrostatic repulsion agents, preventing direct contact and aggregation between pectin chains while allowing the heat-drying process to proceed
2Productivity
If RG-I pectin chains are heated, then drying efficiency is improved, but aggregation between chains increases
Solution Approach 1:
The patent introduces negatively charged polysaccharides as intermediary substances that interfere with the direct interaction between RG-I pectin chains during heating. These intermediaries provide electrostatic repulsion and spatial separation, preventing chain aggregation while allowing efficient heat-drying to proceed
Solution Approach 2:
The patent changes the physical-chemical parameters of the system by adding negatively charged polysaccharides, which alter the electrostatic environment and interaction forces between pectin chains. This parameter change enables the system to withstand thermal energy without aggregating, maintaining both drying efficiency and compositional stability
