Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional gravity-based dropping method is used, then the process is simple, but the production rate is low and particle size is large

Engineering Contradiction:
Improveproduction rateVSAvoidprocess complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies vibration to the dropping system to increase the dropping frequency from traditional low rates to high-speed production. The vibration mechanism enables rapid formation and release of droplets, significantly increasing production rate while maintaining process simplicity through the addition of a vibration source to the existing dropping apparatus.

Inventive Principle:
Principle #18Mechanical vibration

2Ease of manufacture

If traditional coolant-based solidification is used, then the cooling effect is strong, but residual coolant remains and requires additional removal steps

Engineering Contradiction:
Improveprocess simplicityVSAvoidresidual coolant
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes the coolant component from the traditional drop pill preparation process. By replacing coolant-based solidification with gas-phase cooling, the harmful residual coolant is completely eliminated, simplifying the manufacturing process by removing the additional coolant removal step while avoiding contamination issues.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes the liquid coolant-based solidification system with a gas-phase cooling system. This replacement eliminates the need for immiscible liquid coolants and their subsequent removal, simplifying the process while avoiding residual solvent problems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Length of moving object

If traditional dropping method is used, then the equipment is simple, but the particle size is large and cannot be made less than 2.5 mm

Engineering Contradiction:
Improveparticle sizeVSAvoidequipment complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent uses vibration to control droplet formation and size reduction. The vibration frequency and amplitude are optimized to produce smaller droplets that solidify into micro drop pills with particle sizes less than 2.5 mm, achieving the desired size reduction without complex equipment modifications.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent changes the physical parameters of the dropping system, including vibration frequency, dropping height, and gas flow rate, to control and reduce particle size. By optimizing these parameters, the system produces micro drop pills with precise size control below 2.5 mm while maintaining equipment simplicity.

Inventive Principle:
Principle #35Parameter changes

4Loss of time

If traditional drying methods are used, then the drying process is simple, but the drying time is prolonged and volatile components are lost

Engineering Contradiction:
Improvedrying timeVSAvoidevaporation of volatile oil
Core Design Contradiction:
Loss of timeVSObject-generated harmful factors

Solution Approach 1:

The patent changes the drying parameters by using low temperature and controlled gas flow. This approach reduces drying time significantly while preventing the evaporation of volatile oil components through optimized temperature and atmosphere control, avoiding the losses associated with traditional high-temperature drying.

Inventive Principle:
Principle #35Parameter changes
