Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adsorption methods using active carbon are used to remove fermentation inhibitors, then the yield of fermentative production is improved, but the saccharide concentration decreases and production costs increase
Solution Approach 1:
The patent extracts and removes fermentation inhibitors (carbonyl compounds) from the saccharide solution through selective adsorption or chemical transformation, separating the harmful substances from the valuable saccharides without significant loss of saccharide concentration
Solution Approach 2:
The patent introduces intermediary substances such as ammonium ions or other reagents that react with carbonyl compounds to form removable complexes, enabling selective removal of inhibitors while preserving saccharides
2Productivity
If adsorption methods using active carbon are used to remove fermentation inhibitors, then the yield of fermentative production is improved, but production costs increase due to adsorbent production and regeneration
Solution Approach 1:
The patent employs low-cost, easily replaceable removing agents such as ammonium salts or simple chemical reagents that can be added in small amounts and do not require expensive regeneration processes, replacing the need for costly adsorbent regeneration
Solution Approach 2:
The patent changes the chemical parameters of the system by adjusting pH, temperature, or adding specific reagents to transform carbonyl compounds into removable forms, providing a cost-effective alternative to physical adsorption methods
3Productivity
If reduction methods using reducing agents are used to remove fermentation inhibitors, then the yield of fermentative production is improved, but metal salt content increases causing coloration issues
Solution Approach 1:
The patent extracts and removes metal salts and coloration byproducts through additional purification steps such as ion exchange, filtration, or chemical precipitation, separating these harmful substances from the treated saccharide solution
Solution Approach 2:
The patent introduces intermediary substances that selectively bind to metal ions or coloration compounds, enabling their removal without affecting the saccharides or requiring expensive metal-free reducing agents
4Reliability
If heat treatment is applied to sterilize saccharide solution, then microorganism multiplication is controlled, but saccharide degradation increases generating more fermentation inhibitors
Solution Approach 1:
The patent performs preliminary removal of carbonyl compounds through chemical treatment or selective adsorption before heat treatment, preventing their formation during sterilization or enabling effective removal after mild heat treatment
Solution Approach 2:
The patent employs periodic or staged treatment processes, alternating between mild heat treatment for sterilization and chemical treatment for carbonyl compound removal, achieving both sterilization and inhibitor removal without excessive saccharide degradation
