Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective substances to enhance brain function, particularly memory and learning functions, and cognitive function, with existing research on fermented dairy products indicating a potential active ingredient but lacking identification of the specific peptide responsible.
Innovation Solution
Screening peptides derived from milk proteins using the Y maze test and intracerebral microglia activity assessment, identifying specific peptides that enhance memory, learning, and cognitive functions, and producing them through enzymatic treatment of milk proteins with enzymes from microorganisms like Aspergillus, Bacillus, and Rhizopus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fermented dairy products are consumed to enhance brain function, then memory and cognitive function may be improved, but the specific active ingredient and mechanism of action remain unknown
Solution Approach 1:
The patent extracts the specific active peptide成分 from fermented dairy products through systematic isolation and identification. The research team separated and purified the peptide responsible for brain function enhancement, transforming the unknown mixture into a identified, characterizable substance that can be studied and applied reliably.
Solution Approach 2:
The patent uses microglia as an intermediary to study the mechanism of action. By examining how the peptide affects microglial activity (phagocytosis and inflammation), the researchers established a causal link between the peptide and cognitive function enhancement, revealing the biological mechanism without which the effect remained mysterious.
2Reliability
If microglia are excessively activated to remove waste materials, then brain homeostasis is maintained, but inflammatory state is induced causing cognitive function decline
Solution Approach 1:
The patent modifies the activation parameter of microglia through peptide treatment. Instead of excessive activation that causes inflammation, the peptide induces a controlled, moderate activation state that maintains phagocytic function while suppressing harmful inflammatory responses, thus balancing waste removal with prevention of cognitive decline.
Solution Approach 2:
The patent converts the potentially harmful excessive activation of microglia into a beneficial controlled activation. The peptide transforms the harmful inflammatory response into a beneficial protective effect by enhancing phagocytosis while simultaneously suppressing inflammation, turning a double-edged sword into a purely beneficial mechanism.
