Solution Overview

Problem

Existing vehicle diagnosis systems face challenges in setting appropriate storage conditions for diagnostic data, leading to incorrect settings and potential data storage failures when trying to acquire specific driving parameters, as they do not confirm the existence and capabilities of the target ECU within the vehicle's network.

Innovation Solution

A storage condition setting device connected to the vehicle's in-vehicle network that inputs diagnostic items, searches for the target ECU, acquires equipment information, and sets storage conditions only based on the vehicle's capabilities, ensuring correct data storage by confirming the ECU's existence and capabilities before setting storage conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If storage conditions are set without confirming ECU existence and capabilities, then storage condition setting can be performed quickly, but incorrect settings occur leading to data storage failures

Engineering Contradiction:

Improvestorage condition setting speedVSAvoiddata storage success rate

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by searching for the target ECU and acquiring its equipment information before setting storage conditions. This ensures the ECU exists and has the necessary capabilities before attempting to configure storage parameters, preventing failed storage operations while maintaining efficient workflow.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the system searches for and confirms target ECU existence before setting storage conditions, then data storage reliability improves, but the diagnostic process becomes more complex

Engineering Contradiction:

Improvedata storage success rateVSAvoiddiagnostic process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The target ECU autonomously provides its own equipment information in response to a search request from the storage condition setting device. This self-service mechanism eliminates the need for manual configuration or complex external verification processes, simplifying the overall system while ensuring reliable ECU confirmation before storage condition setup.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If manual input of ECU information is required, then flexibility in setting storage conditions is maintained, but operator errors increase leading to incorrect settings

Engineering Contradiction:

Improvestorage condition configuration flexibilityVSAvoidECU information accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system replaces manual mechanical input operations with automated electronic information acquisition. The storage condition setting device automatically searches for and retrieves ECU equipment information through digital communication, eliminating operator input errors while preserving the flexibility to adapt storage conditions to different ECU capabilities through programmatic configuration.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A storage condition setting device searches, from among a plurality of ECUs that reside within an in-vehicle network, for a target ECU corresponding to a diagnostic item that is input to an input unit. In the case that such a target ECU exists, the storage condition setting device acquires from the target ECU equipment information of a vehicle related to storage conditions that correspond to the diagnostic item, and selects and sets as storage condition data in the target ECU only those items that correspond to the equipment information from among the storage conditions.
