Solution Overview

Problem

Existing homogenizing valves face issues with mechanical misalignment due to the actuation of the impact head far from the working area, leading to reduced performance and a shorter useful lifetime of the impact head.

Innovation Solution

A guiding device for the impact head is introduced, featuring a solid body with a cylindrical symmetry and internal grooves for fluid passage, which embraces the impact head and actuates it closer to the working area, reducing misalignments and enhancing precision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the impact head is actuated far from the working area (gap), then the structure is simpler, but mechanical misalignment occurs and performance deteriorates

Engineering Contradiction:

Improvestructure simplicityVSAvoidalignment precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The guiding device is segmented into a guiding body and a sleeve that receives the impact head. The guiding body contains guiding surfaces that engage with the impact head, separating the actuation function from the impact function. This segmentation allows the impact head to be actuated closer to the gap while maintaining structural clarity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guiding device acts as an intermediary between the actuation mechanism and the impact head. It includes a guiding body with guiding surfaces and a sleeve that together provide precise guidance and positioning, mediating the transfer of motion from the actuator to the impact head while minimizing misalignment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the impact head is actuated far from the working area, then the actuation mechanism is easier to implement, but the useful lifetime of the impact head decreases

Engineering Contradiction:

Improveactuation easeVSAvoiduseful lifetime

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The guiding device serves as an intermediary that preserves the ease of actuation while protecting the impact head. The guiding surfaces and sleeve provide smooth guidance during actuation, reducing mechanical shocks and wear on the impact head, thereby extending its useful lifetime.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The guiding device provides beforehand cushioning by incorporating guiding surfaces that ensure smooth engagement and movement. This prevents sudden impacts and mechanical shocks before they can damage the impact head, extending its operational life.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Device complexity

If a shaft integrally fixed to the impact head is used as pusher, then the device is simpler, but mechanical misalignment and reduced performance occur

Engineering Contradiction:

Improvedevice simplicityVSAvoidperformance reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The device is segmented into separate functional components: the guiding body, the sleeve, and the impact head. The guiding body and sleeve work together to provide precise guidance, while the impact head performs the impact function. This segmentation improves reliability by ensuring proper alignment and reducing wear.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guiding device acts as an intermediary between the actuation mechanism and the impact head. The guiding surfaces and sleeve provide precise guidance and positioning, mediating the transfer of motion while minimizing misalignment and improving performance reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)
