Solution Overview

Problem

The effects of static electricity on vehicle operation are not well understood, particularly how it impacts engine output, leading to inefficiencies in fuel economy and engine performance.

Innovation Solution

An engine with nonconductive parts that utilize a self-discharge type static eliminator placed on the outer wall surface of connecting parts to reduce static electricity, thereby lowering the charge carried on these surfaces and improving engine output by reducing intake and exhaust resistance and lubricating oil viscosity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If static electricity is not eliminated from nonconductive engine parts, then the engine structure remains simple, but the engine output decreases due to increased intake resistance, exhaust resistance, and lubricating oil viscosity

Engineering Contradiction:

Improveengine outputVSAvoidengine structure

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The static eliminator is designed to automatically eliminate static electricity from the nonconductive engine part without requiring external power sources or complex control systems. The eliminator uses the existing electric field and charge distribution to create a discharge path, allowing the system to self-regulate and maintain optimal electrical conditions passively

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The static eliminator acts as an intermediary element between the charged nonconductive engine part and the surrounding environment. It provides a controlled path for charge dissipation, mediating the interaction between the static charge and the air molecules to enable safe and effective static electricity elimination

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If a static eliminator is added to eliminate static electricity, then fuel economy improves, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The static eliminator changes the electrical parameters of the engine system by providing a controlled discharge path for static electricity. This modifies the electrical field distribution around the engine components, enabling more efficient combustion and reducing energy losses related to static charge interference

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The static eliminator is designed as a simple, inexpensive component that can be easily manufactured and installed. It uses readily available materials and straightforward construction methods, making it a cost-effective addition that provides significant fuel economy improvements without substantial manufacturing overhead

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If static electricity accumulates on nonconductive engine parts, then manufacturing and installation remain simple, but intake resistance and exhaust resistance increase, reducing engine performance

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The static eliminator is positioned and configured to prevent static electricity from accumulating to harmful levels in the first place. By providing a continuous or periodic discharge path, it proactively counteracts the buildup of static charge before it can significantly impact engine performance or create harmful electrical fields

Inventive Principle:

Principle #9Preliminary anti-action
