Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing resins are used to remove dissolved acid from sugar solutions, then acid removal function is provided, but operating capacity is limited and regeneration is incomplete
Solution Approach 1:
The patent changes the chemical composition parameters of the resin by specifying exact ratios of amino groups (1.4-2.0 eq/L) and quaternary ammonium groups (0.05-0.20 eq/L), along with controlled water retention capacity (40-60%). These parameter optimizations enable both high acid removal capacity and complete regeneration without resin degradation.
Solution Approach 2:
The resin is designed as a composite functional material containing multiple types of basic groups (amino and quaternary ammonium) in specific proportions, combined with a polymeric matrix having controlled water retention. This composite structure achieves synergistic effects for both high operating capacity and complete regenerability.
2Quantity of substance
If resin with high amino group content is used, then operating capacity increases, but osmotic stability deteriorates
Solution Approach 1:
The patent optimizes the water retention capacity parameter to a specific range (40-60%) that balances osmotic stability with amino group content. This parameter control prevents resin particle disintegration in high-osmotic environments while maintaining high acid removal capacity through sufficient amino groups.
Solution Approach 2:
The resin structure is designed with localized functional groups distributed within a stable polymeric matrix. The amino and quaternary ammonium groups are positioned within the resin structure to provide high capacity while the matrix composition maintains osmotic stability, creating different functional zones within the same material.
3Quantity of substance
If quaternary ammonium groups are increased to improve acid removal, then operating capacity increases, but cost and complexity increase
Solution Approach 1:
The patent uses a low but sufficient amount of quaternary ammonium groups (0.05-0.20 eq/L) rather than high concentrations. This partial action approach provides adequate acid removal capacity while avoiding the costs and synthesis complexity associated with high quaternary ammonium content resins. The amino groups provide the primary adsorption function.

Implementation Method 1
it is often desired to treat aqueous solutions that contain one or more monosaccharides in order to remove dissolved acid. One way to remove dissolved acid is to pass the aqueous solution through a bed of adsorbent particles, allowing the dissolved acid to become adsorbed onto the particles
Implementation Method 2
allowing the dissolved acid to become adsorbed onto the particles
