Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If antioxidants (vitamin C derivatives and polyphenolic compounds) are used to protect nucleic acids from light-induced degradation, then nucleic acid stability is improved, but the antioxidants themselves degrade and deteriorate due to high reactivity with oxygen in air during storage and use

Engineering Contradiction:
Improvenucleic acid stabilityVSAvoidantioxidant stability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent employs heteroaromatic ring compounds as antioxidants that are stable during storage and use, replacing the conventional approach of using reactive antioxidants that degrade over time. These compounds provide sustained protection without self-degradation, effectively solving the reliability issue of antioxidant stability while maintaining nucleic acid protection.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Stability of the object's composition

If polyphenolic compounds are used as antioxidants, then nucleic acid protection is achieved, but water solubility is poor limiting their use in aqueous systems

Engineering Contradiction:
Improvenucleic acid protectionVSAvoidwater solubility
Core Design Contradiction:
