Solution Overview

Problem

Existing fluidic rotary distributors for rotating machines face issues with high wear, weight, and production costs due to the use of traditional materials, and are unable to support fluid pressures above 50 bar, limiting their durability and efficiency.

Innovation Solution

A multi-pass fluidic rotary distributor made with polymeric materials, such as PPSU, reinforced with mineral fillers like glass and carbon fibers, which supports high pressures and reduces production costs while maintaining durability and performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional materials (carbon steel, phosphate steel, spheroid cast iron) are used for the inner stem and outer jacket, then the distributor can support high working pressures, but the weight and production cost increase significantly

Engineering Contradiction:
Improvepressure support capabilityVSAvoiddistributor weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent applies composite materials by combining polymer matrix (resin) with mineral fillers (glass fibers, carbon fibers, or aramid fibers) to create a composite structure that maintains high strength and pressure support capability while significantly reducing weight compared to traditional steel materials. The composite material allows the distributor to withstand high pressures without requiring dense metal construction.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the material parameters from traditional metals to advanced polymer composites, specifically using resins reinforced with mineral fillers. This parameter change enables the distributor to achieve comparable mechanical strength to steel while reducing density and weight, directly addressing the contradiction between strength and weight.

Inventive Principle:
Principle #35Parameter changes

2Strength

If traditional materials (carbon steel, phosphate steel, spheroid cast iron) are used for the inner stem and outer jacket, then the distributor can support high working pressures, but the production cost increases due to material expenses

Engineering Contradiction:
Improvepressure support capabilityVSAvoidproduction cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent uses polymer composite materials as an alternative to expensive steel materials. The composite structure made of resin and mineral fillers provides comparable mechanical strength at lower material cost, directly reducing production expenses while maintaining the ability to support high working pressures.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent adopts a cost-effective material strategy by using polymer composites that are cheaper than traditional steel materials. While the service life remains long, the lower material cost and potentially simpler manufacturing process make this an economically advantageous solution compared to expensive metal construction.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Weight of moving object

If the distributor is made with polymeric materials reinforced with mineral fillers, then the weight and production cost are reduced, but the ability to support high working pressures is questioned

Engineering Contradiction:
Improvedistributor weightVSAvoidpressure support capability
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent directly addresses this concern by using composite materials with mineral fillers (glass fibers, carbon fibers, or aramid fibers) embedded in a polymer matrix. These fillers provide reinforcement that enables the lightweight polymer structure to withstand high working pressures, proving that weight reduction does not necessarily compromise strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies local quality enhancement by incorporating mineral fillers specifically in regions requiring high strength and pressure resistance. The composite structure provides localized reinforcement where needed, allowing the overall structure to remain lightweight while maintaining adequate strength for high-pressure applications.

Inventive Principle:
Principle #3Local quality

4Ease of manufacture

If the distributor is made with polymeric materials reinforced with mineral fillers, then the production cost is reduced, but the durability and service life are questioned

Engineering Contradiction:
Improveproduction costVSAvoidservice life
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent uses composite materials that combine the cost advantages of polymers with the durability enhancement of mineral fillers. The reinforced composite structure provides improved mechanical properties and wear resistance compared to pure polymers, ensuring adequate service life and reliability for industrial applications while maintaining lower production costs.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent incorporates mineral fillers in advance during material fabrication to preemptively enhance the structural integrity and durability of the distributor. This beforehand reinforcement ensures that the polymer composite can withstand operational stresses and maintain service life comparable to or exceeding traditional materials, despite the lower base material cost.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
