Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current methods are used to enhance hematopoietic stem cell transplantation efficiency, then transplantation efficiency is limited, but CD184 expression regulation difficulty increases

Engineering Contradiction:
Improvetransplantation efficiencyVSAvoidCD184 expression regulation difficulty
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses small molecule compounds to change the expression level of CD184 protein on HSC surface through chemical parameter modulation. This resolves the contradiction by providing a simple chemical parameter control method that directly enhances transplantation efficiency without complex regulatory mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Speed

If CD184 expression is increased to improve homing ability, then migration ability improves, but other HSC functions may be affected

Engineering Contradiction:
Improvemigration abilityVSAvoidother HSC functions
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent applies local quality by specifically enhancing CD184 expression on HSC surface while maintaining other cellular functions intact. The small molecule compounds selectively modulate CD184 without affecting other HSC properties, achieving improved migration ability while preserving reliability of other functions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses partial action by selectively targeting only the CD184 expression pathway for enhancement, while leaving other HSC functions at their normal levels. This selective modulation improves migration ability without unnecessarily altering other cellular functions that maintain reliability.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If multiple treatment methods are applied to improve transplantation efficiency, then transplantation efficiency may improve, but operational complexity increases

Engineering Contradiction:
Improvetransplantation efficiencyVSAvoidoperational complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges multiple potential treatment approaches into a single small molecule compound treatment. Instead of applying multiple separate treatments to improve transplantation efficiency, the invention uses one compound that directly enhances CD184 expression, thereby simplifying operational complexity while maintaining improved transplantation efficiency.

Inventive Principle:
Principle #5Merging (Combining)
