Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water is used as solvent in reduction reaction, then reaction completeness is improved, but volume efficiency deteriorates and reaction time increases

Engineering Contradiction:
Improvereaction completenessVSAvoidvolume efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention changes the solvent system from pure water to a water-containing organic solvent system, and adjusts the pH parameter to 5 or below. This parameter change allows the reaction to maintain completeness while improving volume efficiency and reducing reaction time, as the organic solvent component enhances solubility of coenzyme Q10 and reaction kinetics.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If reaction promoters such as basic substances or bisulfite are added, then reaction time is shortened, but process complexity increases due to additional removal steps

Engineering Contradiction:
Improvereaction timeVSAvoidprocess complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The invention uses the water-containing organic solvent system at pH 5 or below to inherently promote the reduction reaction without requiring additional reaction promoters. The solvent system itself creates favorable reaction conditions, eliminating the need for separate promoter addition and removal steps, thus reducing process complexity while maintaining short reaction time.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If conventional reduction methods are used, then reduced coenzyme Q10 is produced, but additional steps are required to remove reaction promoters

Engineering Contradiction:
Improveproduct purityVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The invention extracts or eliminates the need for reaction promoters from the conventional process by using the water-containing organic solvent system at pH 5 or below, which inherently facilitates complete reduction. This removes the problematic component (reaction promoters) that required additional removal steps, thereby improving production efficiency while maintaining product purity.

Inventive Principle:
Principle #2Taking out (Extraction)
