Solution Overview

Problem

Existing hose hangers for railway vehicles fail to absorb the energy generated when glad hand fittings decouple, leading to increased reaction forces, degradation, and potential derailment, with frequent replacements needed due to chain and connector degradation.

Innovation Solution

A hose hanger system comprising an attachment clip, an elastic support made of vulcanized rubber, and a carabiner assembly connector, designed to absorb energy and maintain hoses at a desired height, reducing cross-loading and enhancing durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a chain support is used to suspend the air brake hose, then the hose can be supported and positioned, but the chain cannot absorb energy during decoupling events, leading to increased reaction forces and degradation

Engineering Contradiction:
Improvehose support reliabilityVSAvoidreaction force resistance
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent changes the physical state and material properties of the support from rigid (chain) to elastomeric (rubber material), allowing the material to deform and absorb energy during decoupling events while maintaining support functionality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite construction combining an elastomeric material with embedded chain elements, creating a hybrid structure that provides both energy absorption capabilities and structural strength to resist reaction forces

Inventive Principle:
Principle #40Composite materials

2Strength

If a rigid chain and connector system is used, then the hose hanger can maintain structural integrity, but the system is susceptible to degradation from cross-loading and impact forces, requiring frequent replacements

Engineering Contradiction:
Improvestructural integrityVSAvoidhose hanger service life
Core Design Contradiction:
StrengthVSDuration of action of stationary object

Solution Approach 1:

The patent changes the material from rigid metal chain to elastomeric rubber material, which can deform under load and return to original shape, resisting degradation from repeated cross-loading and impact forces throughout the service life

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The elastomeric material inherently provides cushioning before impact events occur, absorbing and dissipating energy from decoupling events and lateral forces, preventing degradation that would lead to premature replacement

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

3Ease of operation

If traditional metal chain supports are used, then installation is simple, but the system allows excessive hose movement and cannot prevent unintended braking events

Engineering Contradiction:
Improveinstallation simplicityVSAvoidhose position stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent changes the support material to elastomeric rubber with specific durometer properties, providing friction and resistance that stabilize hose position while maintaining flexibility and ease of installation

Inventive Principle:
Principle #35Parameter changes
