Solution Overview

Problem

The existing managing system for marine internal combustion engines relies on users to perform maintenance, which can lead to improper maintenance due to lack of knowledge or attention, resulting in engine degradation.

Innovation Solution

An information providing system that includes an internal combustion engine with an electronic control type fuel injecting device and an operation permitting device that supplies electric power for starting, along with an information providing device that offers usage information based on operation history, transmitted via a wireless unit to a server for user access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users perform maintenance themselves, then maintenance cost is reduced, but maintenance quality deteriorates due to lack of knowledge or attention

Engineering Contradiction:
Improvemaintenance qualityVSAvoiduser maintenance capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces an information providing device as an intermediary between the maintenance center and the user. This device receives operation history from the engine, determines maintenance timing, and provides maintenance information to the user through various output methods (display, sound, communication device). This intermediary system bridges the knowledge gap between professional maintenance centers and ordinary users, enabling users to perform maintenance appropriately without requiring specialized knowledge.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If maintenance information is provided to users, then maintenance quality improves, but system complexity increases

Engineering Contradiction:
Improvemaintenance qualityVSAvoidinformation providing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The information providing device is designed with multi-functionality to reduce overall system complexity. It can provide maintenance information through multiple output methods (display unit, sound output unit, communication device) and can handle various types of information (maintenance timing, operation history, degradation degree). This universal design allows a single device to fulfill multiple functions rather than requiring separate systems for each function.

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

Solution Approach 2:

The system enables self-service by automatically monitoring engine operation history and determining maintenance timing without requiring external intervention. The information providing device autonomously processes operation history data, calculates degradation degrees, and generates maintenance information, reducing the need for complex manual monitoring systems.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If operation history is transmitted to information providing device, then maintenance timing accuracy improves, but data transmission requirements increase

Engineering Contradiction:
Improvemaintenance timing accuracyVSAvoiddata transmission load
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system extracts only the essential operation history data needed for maintenance timing determination, rather than transmitting all possible engine data. The information providing device receives specific parameters (operation hours, load conditions, temperature) and processes them to determine maintenance timing. This selective extraction reduces data transmission requirements while maintaining sufficient accuracy for maintenance scheduling.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An information providing system for an internal combustion engine includes an internal combustion engine, which includes an electronic control type fuel injecting device, an operation permitting device, which can be removably mounted on the internal combustion engine, wherein while the operation permitting device is mounted on the internal combustion engine, which is associated with the operation permitting device in advance, the operation permitting device supplies electric power to the fuel injecting device at a start of the internal combustion engine, and an information providing device, which provides information about use of the internal combustion engine to a destination associated with a user of the operation permitting device, based on an operation history of the associated internal combustion engine. The operation permitting device includes a transmission unit that transmits, to the information providing device, user information of the operation permitting device and the operation history of the associated internal combustion engine.
