Solution Overview

Problem

Existing vehicle management systems struggle to effectively manage the varying lifetimes of components such as batteries across different vehicles and usage environments, leading to uneven degradation and potential component failure.

Innovation Solution

A vehicle management system that periodically adjusts the combinations of vehicles, components, and users based on degradation values and usage values, using multiple indices to determine optimal combinations that extend the lifetime of components and prevent premature failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If vehicles are allocated to management environments based on estimated degradation values, then component lifetime is extended, but system complexity increases due to periodic reassignment and multiple index calculations

Engineering Contradiction:

Improvecomponent lifetimeVSAvoidsystem complexity

Core Design Contradiction:

Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The system dynamically reassigns vehicles to management environments based on changing degradation values and usage tendencies. Instead of static allocation, the management server periodically recalculates degradation values and reassigns vehicles to optimize component lifetime, making the system adaptive to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system calculates estimated degradation values and usage tendencies in advance to predict future component behavior. By performing preliminary assessments of degradation risks and usage patterns, the system can proactively reassign vehicles before actual degradation occurs, preventing premature failure.

Inventive Principle:

Principle #10Preliminary action

2Duration of action of stationary object

If multiple indices are used to determine optimal combinations, then component lifetime extension is achieved, but calculation complexity and processing time increase

Engineering Contradiction:

Improvecomponent lifetimeVSAvoidprocessing time

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The management server performs degradation value calculations and reassignment operations periodically rather than continuously. This periodic action reduces processing time by executing complex calculations at scheduled intervals based on usage milestones or time periods, rather than requiring constant monitoring and recalculation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses automatically collected usage data from vehicle sensors and management records to calculate degradation values without requiring external intervention. By self-gathering and processing usage information, the system minimizes the time needed for manual assessments and accelerates the reassignment process.

Inventive Principle:

Principle #25Self-service

3Duration of action of stationary object

If vehicles with higher degradation values are allocated to environments with lower degradation tendencies, then component lifetime is extended, but allocation flexibility decreases

Engineering Contradiction:

Improvecomponent lifetimeVSAvoidallocation flexibility

Core Design Contradiction:

Duration of action of stationary objectVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts vehicle allocations based on real-time degradation values and usage tendencies. Rather than fixed allocation categories, the management server continuously evaluates and reassigns vehicles to management environments that best match their current degradation state, maintaining flexibility while extending component lifetime.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes allocation parameters based on degradation values and usage tendencies. By adjusting which vehicles are allocated to which management environments according to their specific degradation characteristics and usage patterns, the system maintains allocation flexibility while optimizing for component lifetime extension.

Inventive Principle:

Principle #35Parameter changes
