Solution Overview

Problem

Existing lubricating nozzles for internal combustion engines are cumbersome to assemble, costly due to brazing requirements, and heavy due to metal materials, complicating precise positioning and orientation within the engine block.

Innovation Solution

A lubricating nozzle design featuring a metal spray nozzle body with a plastic orienting plate and abutment means, eliminating the need for brazing and reducing weight by using plastic materials for the orienting plate, which simplifies assembly and reduces production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If brazing is used to connect the spray nozzle body and orienting plate, then the orientation stability is improved, but the manufacturing complexity and cost increase

Engineering Contradiction:

Improveorientation stabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the brazing process (thermal/chemical joining) with a mechanical connection system consisting of a retaining screw and complementary orienting means. The retaining screw fastens the spray nozzle body to the orienting plate, while the complementary orienting means (protrusions and recesses) ensure precise angular positioning without requiring thermal joining processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The orienting plate serves as an intermediary component between the spray nozzle body and the engine block. It provides both mechanical support and precise orientation guidance through its complementary orienting means, eliminating the need for direct brazing between the nozzle body and engine block while maintaining stable positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If metal materials are used for the spray nozzle body and orienting plate, then the mechanical strength is improved, but the weight increases

Engineering Contradiction:

Improvemechanical strengthVSAvoidnozzle weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent employs a composite construction where the spray nozzle body is made of metal (for strength and pressure resistance) while the orienting plate is made of plastic material (for weight reduction). This composite approach allows each component to be made from the most suitable material for its specific function, optimizing both strength and weight characteristics.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

Different parts of the nozzle assembly use different materials optimized for their specific requirements: the spray nozzle body uses metal for withstanding oil pressure and mechanical stress, while the orienting plate uses plastic for reduced weight since it primarily provides positioning and orientation functions rather than structural support.

Inventive Principle:

Principle #3Local quality

3Reliability

If brazing steps are used to assemble the nozzle, then the connection reliability is improved, but the production cost increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a plastic orienting plate instead of a metal one, which reduces material cost and eliminates the need for expensive brazing operations. The plastic plate provides sufficient functionality for orientation and positioning at a lower cost, making the overall assembly more economically viable.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A lubricating nozzle comprising a metal spray nozzle body comprising a contact surface, the spray nozzle body comprising an axial channel opening out onto the contact surface, a retaining screw, and an orienting plate. The spray nozzle body is mounted inside the hole such that it abuts against a first face of the orienting plate, and such that the contact surface of the body is flush with a second face (106b) of the orienting plate opposite the first face, the spray nozzle body and the orienting plate (106) comprising a first complementary orienting structure which engages such that the oil outlet is oriented, according to a predetermined orientation relative to the first orienting structure, the orienting plate (106) further comprising a second orienting structure designed to orient the plate on the engine block.
