Solution Overview

Problem

Existing pressure relief systems for fluid transport in conduits are complex and lack a simple mechanism to safely release pressure when it exceeds a threshold while also providing operator notification.

Innovation Solution

A pressure relief apparatus comprising a primary conduit with a secondary conduit intersecting at an angle, featuring a rupture disk that fails to relieve pressure and alert operators when fluid pressure exceeds a set threshold, minimizing turbulent flow and utilizing a fluid directing apparatus to direct relieved fluid to a specific location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If complex mechanical pressure measurement and valve opening devices are used, then pressure control precision is improved, but device complexity increases

Engineering Contradiction:

Improvepressure threshold detectionVSAvoidpressure relief system structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a disposable rupture disk that fails at a predetermined pressure threshold, replacing complex mechanical pressure measurement and valve systems. The rupture disk is a simple, inexpensive, single-use component that provides reliable pressure relief without requiring complex sensing or actuation mechanisms, thus resolving the contradiction between measurement precision and device complexity.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent extracts the pressure relief function from complex mechanical valve systems and implements it through a simple rupture disk mechanism. By separating the pressure relief function from the main fluid transport system and using a dedicated rupture disk in a secondary conduit, the system achieves precise pressure threshold detection without the complexity of integrated mechanical valves and sensors.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If pressure relief apparatus is installed in the primary conduit, then pressure relief effectiveness is improved, but fluid transport efficiency deteriorates due to turbulent flow

Engineering Contradiction:

Improvepressure relief effectivenessVSAvoidfluid transport efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments the pressure relief function from the main fluid transport path by installing a secondary conduit that branches off from the primary conduit. The rupture disk is placed in this secondary conduit rather than blocking the primary flow path. This segmentation allows the primary conduit to maintain laminar flow for efficient fluid transport while the secondary conduit provides pressure relief functionality, resolving the contradiction between reliability and productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The secondary conduit acts as an intermediary between the primary conduit and the pressure relief mechanism. Fluid under excessive pressure is diverted into the secondary conduit where the rupture disk provides relief, rather than directly interfering with the primary fluid transport. This intermediary structure maintains efficient fluid transport in the primary conduit while ensuring effective pressure relief through the secondary path.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A pressure relief apparatus is disclosed herein. The pressure relief apparatus comprises a primary conduit for transporting fluid in a given direction. The pressure relief apparatus also includes a secondary conduit intersecting the primary conduit at an angle such that the secondary conduit extends from away from the primary conduit in a direction opposite of the given direction of the transported fluid in the primary conduit. The pressure relief apparatus further comprises a rupture disk disposed in the secondary conduit designed to fail when pressure of the transported fluid in the primary conduit increases above a desired pressure threshold. A method of passing fluid through the pressure relief apparatus is also provided herein.
