Solution Overview

Problem

Conventional methods for installing aftermarket fuel sensors in internal combustion engines are difficult, unreliable, and prone to leakage and structural issues due to ethanol damage, which complicates retrofitting and affects downstream fuel injection components.

Innovation Solution

A fuel diverter block system that intercepts the original equipment manufacturer (OEM) fuel line at its connection points, providing structural support and redirecting fuel flow through a Z-shaped pattern without requiring external lines, using corrosion-resistant materials like aluminum to maintain the engine's original dimensions and prevent damage from ethanol-based fuels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional methods are used to install aftermarket fuel sensors by disconnecting and cutting fuel lines, then sensors can be installed, but installation becomes difficult and unreliable with leakage issues

Engineering Contradiction:
Improvesensor installation reliabilityVSAvoidinstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

A sensor adapter assembly serves as an intermediary component that interfaces with the existing fuel line without requiring disconnection or cutting. The adapter includes a sensor holder that receives the fuel sensor and a connection interface that couples to the fuel line, enabling reliable sensor installation while maintaining fuel flow integrity and preventing leakage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If external fuel lines are used to install sensors, then sensors can be positioned, but the engine compartment dimensions are exceeded and retrofitting becomes challenging

Engineering Contradiction:
Improveretrofitting reliabilityVSAvoidengine compartment volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The sensor adapter assembly is designed to nest within the existing fuel line structure. The adapter fits inside or alongside the original fuel line components, and the sensor holder accommodates the fuel sensor within the confined fuel line space, allowing sensor installation without exceeding engine compartment dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If conventional fuel line connections are used, then fuel flow can be redirected, but leaking occurs at connection points

Engineering Contradiction:
Improveconnection reliabilityVSAvoidleakage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The adapter assembly acts as an intermediary connection device that provides sealed interfaces between the fuel line and sensor holder. The connection interface includes sealing mechanisms that prevent fuel leakage at connection points while maintaining proper fuel flow to the engine.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems, methods, and a kit of two diverter blocks are provided for diverting a fluid from a fluid line and directing the fluid through a sensor. Fluid flows into a first a first diverter block and into a sensor before flowing out of the sensor and into a second diverter block, then into a downstream fluid line.
