Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the composition has high viscosity and strong adhesion, then the composition can maintain its structure and stability, but the composition cannot be uniformly mixed and sprayed with the refrigerant

Engineering Contradiction:
Improvecomposition stabilityVSAvoidspray uniformity
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

A guide member is introduced as an intermediary component between the composition supply and refrigerant spray streams. The guide member includes a guide surface that directs the composition flow and interacts with the refrigerant spray to facilitate mixing. This intermediary structure enables uniform mixing of high-viscosity composition with refrigerant by controlling the flow interaction between the two streams.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mixing module implements local quality by providing a dedicated guide surface on the guide member that is specifically designed to interact with the composition flow. The guide surface has specific geometric characteristics (inclination angle, positioning) that create localized flow patterns to ensure uniform mixing in the critical mixing region, while other parts of the module maintain their primary functions.

Inventive Principle:
Principle #3Local quality

2Speed

If the composition is sprayed at low temperature to improve penetration, then penetration performance is improved, but the composition may freeze due to the refrigerant

Engineering Contradiction:
Improvepenetration speedVSAvoidfreezing
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The module converts the potentially harmful effect of the refrigerant's low temperature into a beneficial cooling effect for the composition. By controlling the mixing process and using the guide member to ensure proper contact between refrigerant and composition, the system achieves the desired cooling for penetration enhancement while preventing freezing through controlled temperature management and rapid delivery.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If the composition is moved by negative pressure generated by refrigerant spray, then the composition can be delivered without additional pumping, but the composition flow may be unstable

Engineering Contradiction:
Improvesystem simplicityVSAvoidflow stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The system uses the refrigerant spray's own kinetic energy and negative pressure generation to drive the composition flow, eliminating the need for separate pumping mechanisms. The guide member is designed to optimize this self-service approach by directing the composition flow into the refrigerant spray stream, ensuring stable mixing and delivery using the refrigerant's inherent flow characteristics.

Inventive Principle:
Principle #25Self-service

4Manufacturing precision

If the composition is sprayed in a spiral form on the refrigerant spray stream, then mixing efficiency is improved, but the module structure becomes more complex

Engineering Contradiction:
Improvemixing uniformityVSAvoidmodule structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The guide member incorporates a curved guide surface that directs the composition flow in a spiral or curved path as it enters the refrigerant spray stream. This curvature in the flow path enhances mixing efficiency by creating vortex-like patterns and increasing contact between composition and refrigerant, while the guide member itself remains a relatively simple single-piece component that does not significantly increase overall module complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

In a module mixing and spraying a refrigerant and a composition, the module has a mixing space where a refrigerant spray unit is disposed and an inlet hole is formed, and when the refrigerant is sprayed, a negative pressure is formed in the inlet hole to allow the composition to be introduced, so that the refrigerant and the composition may be sprayed while being mixed together. At this point, in case of spraying the refrigerant and the composition in the mixed state, various problems may occur, and a guide member having various shapes may be disposed in the mixing space in order to solve the various problems.
