Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If small-molecule activators for SIRT6 are developed to regulate deacetylation activity, then therapeutic potential for treating diseases related to SIRT6 activity is improved, but currently no effective small-molecule activators exist for SIRT6

Engineering Contradiction:
ImproveSIRT6 deacetylation activity regulationVSAvoidavailability of small-molecule activators
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by systematically varying molecular parameters including substituent types (halogen, hydroxyl, nitro, amino, carboxyl, etc.), positions (R1-R13), and nitrogen-containing heterocyclic ring structures to optimize SIRT6 binding affinity and deacetylation activation. This structure-activity relationship optimization resolves the contradiction by creating a series of compounds with progressively improved regulatory reliability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite molecular design by combining multiple functional elements: a core structure with specific substituents (R1-R13), nitrogen-containing heterocyclic rings, and pharmacologically acceptable salts. This composite approach creates a multifunctional molecule that simultaneously achieves SIRT6 binding, allosteric activation, and pharmaceutical stability

Inventive Principle:
Principle #40Composite materials

2Power

If compound structure is optimized for SIRT6 binding affinity, then deacetylation activity enhancement is improved, but structural complexity increases

Engineering Contradiction:
Improvedeacetylation activity enhancementVSAvoidcompound structure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The patent segments the molecule into distinct functional regions: a core structure, multiple substituent positions (R1-R13) that can be independently optimized, and nitrogen-containing heterocyclic ring components. This segmentation allows systematic optimization of binding affinity at each region while maintaining overall structural manageability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning specific functional roles to different parts of the molecule: certain substituents (R1-R5) optimize SIRT6 binding, while others (R6-R13) modulate pharmacological properties. The nitrogen-containing heterocyclic rings provide specific allosteric activation functionality. This localized functional assignment enhances deacetylation activity without requiring uniform complexity throughout the entire structure

Inventive Principle:
Principle #3Local quality
