Solution Overview

Problem

Households often lack tools to coordinate vehicle usage effectively to minimize environmental impact due to limited knowledge of vehicle environmental impacts and individual metrics, leading to increased overall environmental impact.

Innovation Solution

A vehicle management system that includes processors and memory to determine selection zones, generate preference maps, and assign vehicle preference scores based on environmental impact, optimizing vehicle storage and usage within these zones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If households use multiple vehicles without coordination, then transportation needs are met, but environmental impact increases due to lack of awareness and tools for minimizing carbon emissions

Engineering Contradiction:
Improveenvironmental impactVSAvoidvehicle management complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system enables vehicles to automatically determine their own preference scores based on environmental metrics, and automatically position themselves in optimal storage locations without human intervention. The vehicle management system autonomously coordinates vehicle selection and positioning, allowing the system to serve itself in minimizing environmental impact while managing multiple vehicles.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where vehicle environmental metrics are continuously monitored, preference scores are dynamically calculated based on current conditions, and vehicle positions are adjusted accordingly. This closed-loop control ensures the system adapts to changing conditions and maintains optimal environmental performance.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If environmentally friendly vehicles are strategically positioned for acceptance, then environmental impact is reduced, but system complexity increases due to preference mapping and scoring mechanisms

Engineering Contradiction:
Improvecarbon emissionsVSAvoidpreference map generation
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system transforms complex environmental assessment into a simplified preference score parameter that quantifies environmental friendliness. By changing multiple environmental parameters (emissions, efficiency, fuel type) into a single composite preference score, the system reduces complexity while maintaining environmental optimization capabilities.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The vehicle management system divides the storage zone into segmented areas based on preference scores, creating distinct preference zones. This segmentation allows environmentally friendly vehicles to be automatically directed to optimal locations without requiring complex real-time decision-making across the entire storage area.

Inventive Principle:
Principle #1Segmentation

3Productivity

If vehicle preference scores are determined based on environmental metrics, then environmentally friendly vehicles are promoted, but measurement and calculation complexity increases

Engineering Contradiction:
Improveenvironmental efficiencyVSAvoidenvironmental impact measurement
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The preference score system serves multiple functions simultaneously: it ranks vehicles by environmental friendliness, guides vehicle positioning, and provides a basis for automated selection. This multi-functional parameter eliminates the need for separate measurement and decision-making systems, reducing overall complexity while improving environmental efficiency.

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