Existing technologies face challenges in safely testing the performance of safety valves used in hydrogen fuel storage, transportation, and charging, as they fail to prevent explosions and flying debris when ultra-high pressure gas is ejected.

Innovation Solution

A heating test apparatus with an explosion-proof chamber, a sample-holding module, a benchtop module, and a controller, which simulates high-temperature and high-pressure conditions to test the safety valve's performance while ensuring safety through an explosion-proof design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If safety valve performance testing is conducted under ultra-high pressure and high temperature conditions, then the reliability of safety verification is improved, but the risk of explosions and flying debris increases

Engineering Contradiction:
Improvesafety valve performance verificationVSAvoidexplosion risk and flying debris
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system divides the testing environment into separate functional zones: a high-pressure gas supply system, a heating furnace for temperature control, an explosion-proof chamber for containment, and a control area. This spatial segmentation allows reliable testing under extreme conditions while isolating hazards to specific enclosed regions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces multiple intermediary safety components including pressure regulators, temperature control systems, and explosion-proof barriers that mediate between the extreme test conditions and the operators/environment. These intermediaries enable reliable safety valve testing while preventing direct exposure to explosions and flying debris.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If hydrogen fuel is used for energy production, then environmental pollution is reduced, but the risk of fires and explosions increases

Engineering Contradiction:
Improveenvironmental pollutionVSAvoidfire and explosion risk
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The system employs an inert atmosphere approach by using controlled environments with regulated oxygen levels and inert gas purging in the explosion-proof chamber. This allows hydrogen fuel to be handled and tested while minimizing the risk of fire and explosion, enabling clean energy research without proportionally increasing safety risks.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The patent implements beforehand cushioning through explosion-proof chambers designed to contain and dissipate explosion energies, pressure relief valves, and emergency shutdown systems. These preventive measures are built into the system architecture before testing begins, allowing hydrogen fuel utilization while cushioning against potential fire and explosion hazards.

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

3Device complexity

If traditional safety valve testing methods are used, then device complexity is reduced, but the ability to verify performance under extreme conditions is insufficient

Engineering Contradiction:
Improvetesting apparatus structureVSAvoidperformance verification under extreme conditions
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The testing system is designed with multi-functionality to handle various extreme conditions (ultra-high pressure, high temperature, different gas types) using a unified platform. The explosion-proof chamber, heating furnace, and pressure control systems can accommodate different safety valve configurations and test scenarios, achieving comprehensive performance verification without proportionally increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
