Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional methods are used to obtain wheat bran fiber, then the process is simpler, but the removal of environmental pollutants and phytates is inefficient
Solution Approach 1:
The patent applies preliminary action by pre-soaking wheat bran in calcium carbonate solution before the main processing steps. This pre-treatment prepares the bran surface and structure, making subsequent pollutant and phytate removal more effective. The calcium carbonate soaking creates favorable conditions for the upcoming acid treatment and extraction processes.
Solution Approach 2:
The patent uses citric acid as an intermediary substance to facilitate the removal of phytates and pollutants. The citric acid interacts with calcium carbonate and phytates in a controlled manner, enabling efficient chelation and extraction of harmful substances without directly applying harsh chemicals to the bran.
2Loss of substance
If phytates are not removed from wheat bran, then the process is simpler, but bioelements are lost through complexation
Solution Approach 1:
The patent converts the harmful effect of phytates (which bind and trap bioelements) into a beneficial process. By using citric acid to chelate calcium and disrupt phytate-calcium-bioelement complexes, the method releases trapped bioelements back into available forms. The phytate structure itself is broken down, transforming from a harmful complexing agent to a processed component that no longer interferes with nutrient availability.
3Stability of the object's composition
If resistant starches are formed during processing, then the fiber structure is more stable, but the nutritional quality decreases
Solution Approach 1:
The patent carefully controls processing parameters (temperature, pH, treatment duration) to modify the starch structure without creating resistant starches. By maintaining specific temperature ranges and using controlled acid treatment, the method preserves starch digestibility while still achieving the desired fiber structure stability and contaminant removal.
