Solution Overview

Problem

Existing vehicle management systems fail to balance deterioration due to exposure to ultraviolet rays among multiple vehicles effectively.

Innovation Solution

A vehicle management system that includes an exposure amount calculation unit to determine the ultraviolet exposure of each vehicle, a selection unit to balance exposure amounts among vehicles, and a dispatch instruction unit to dispatch vehicles with similar exposure amounts, using solar radiation meters for measurement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vehicles are dispatched without considering ultraviolet exposure amounts, then dispatch efficiency is improved, but deterioration due to ultraviolet exposure becomes unbalanced among vehicles

Engineering Contradiction:

Improvedispatch efficiencyVSAvoiduniformity of deterioration

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The system continuously monitors ultraviolet exposure amounts for each vehicle and uses this feedback information to adjust future dispatch decisions, selecting vehicles with lower cumulative exposure to maintain balanced deterioration across the fleet

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes the dispatch selection criterion from simple availability to a parameter-based selection that considers cumulative ultraviolet exposure amounts, thereby balancing deterioration while maintaining dispatch efficiency

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If vehicles are selected based on balancing ultraviolet exposure amounts, then deterioration uniformity is improved, but dispatch flexibility deteriorates

Engineering Contradiction:

Improveuniformity of deteriorationVSAvoiddispatch flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system applies partial balancing by considering ultraviolet exposure as one factor among multiple dispatch criteria, rather than strictly enforcing equal exposure distribution, thus maintaining adequate dispatch flexibility while achieving sufficient deterioration uniformity

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If solar radiation meters are installed in all vehicles to measure exposure, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improveexposure amount measurementVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The solar radiation meters serve multiple functions: they measure ultraviolet exposure for deterioration management, provide data for balanced dispatch selection, and can potentially be used for other solar-related measurements, justifying the added device complexity through multi-functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The vehicle management system includes an exposure amount calculation unit that calculates an exposure amount by ultraviolet rays of the vehicle, a selection unit that selects one vehicle from the plurality of vehicles so that the exposure amount between the vehicles is the same based on the exposure amount, and a dispatch instruction unit that gives an instruction to dispatch the selected vehicle.
