Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-speed stirring is used to form emulsion in two-liquid phase reactions, then emulsion-forming ability is improved, but energy consumption increases significantly

Engineering Contradiction:

Improveemulsion-forming abilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The liquid dispersion device is divided into multiple functional components: a suction portion for drawing in liquid, a rotary shaft for rotation, and an ejection portion for discharging liquid. This segmentation allows each component to perform its specific function efficiently, reducing overall energy consumption while maintaining effective liquid dispersion and emulsion formation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces vertical movement dimension by having the ejection portion extend in a direction inclined with respect to the suction portion. This three-dimensional configuration enables the liquid to be ejected upward and outward, creating more effective mixing and emulsion formation with lower energy input compared to traditional horizontal stirring mechanisms.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If vigorous stirring is applied to accelerate transesterification reaction, then reaction rate is improved, but energy load on stirrer increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSPower

Solution Approach 1:

The liquid dispersion device utilizes the rotational motion of the rotary shaft to automatically draw in and eject liquid through centrifugal force and pressure differential. The system serves itself by using the rotation to create the necessary flow and mixing effects without requiring additional high-power stirring mechanisms, thus reducing overall power consumption while maintaining effective reaction acceleration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention employs hydraulic principles by using the rotary shaft to create pressure differential and flow within the liquid. The suction portion and ejection portion are designed to utilize fluid dynamics and pressure gradients to move liquid through the system, reducing the need for high-power mechanical stirring and thereby lowering power consumption while maintaining effective reaction rate acceleration.

Solution Approach 1:

The ejection portion is designed with an inclined configuration that directs liquid flow in a curved, upward trajectory. This curved path creates more effective mixing and emulsion formation by introducing vertical component to the flow, allowing low-energy operation to still achieve good emulsion formation through the geometric design of the ejection pathway.
