Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electric vehicles are recharged using traditional charging infrastructure, then vehicles can be powered sustainably, but recharging time is measured in hours causing fleet readiness issues
Solution Approach 1:
The system performs preliminary actions by predicting future charging needs of vehicles based on scheduled tasks and current battery levels. It proactively identifies vehicles that will require charging before their tasks begin, allowing charging to be initiated in advance during off-peak hours or lower-cost periods, thus reducing wait time while maintaining sustainable energy use
Solution Approach 2:
The system dynamically adjusts charging strategies based on real-time conditions including vehicle location, task schedules, battery state, and charging station availability. It continuously optimizes charging timing and location assignments to minimize fleet downtime while utilizing available sustainable charging infrastructure efficiently
2Ease of operation
If fleet operators manually manage charging assignments, then control over vehicle deployment is maintained, but scheduling complexity increases and operational efficiency decreases
Solution Approach 1:
The system implements continuous feedback loops that monitor vehicle battery levels, scheduled tasks, charging station status, and fleet utilization metrics. This feedback automatically informs charging assignments and schedule adjustments, reducing manual intervention complexity while preserving operator oversight and control capabilities through centralized visibility
Solution Approach 2:
The system enables self-service by allowing vehicles to be automatically assigned to charging stations based on their needs and fleet priorities without manual operator intervention for each assignment. The automated system handles the complex scheduling while operators retain strategic control through configuration and monitoring interfaces
3Productivity
If charging stations are distributed widely to support fleet operations, then vehicle availability improves, but infrastructure cost and management complexity increase
Solution Approach 1:
The system treats charging stations as universal resources that can serve multiple vehicles with different requirements. It creates a unified charging network where any compatible vehicle can access any available charging station, maximizing utilization of existing infrastructure while reducing the need for dedicated charging points at each fleet location
Solution Approach 2:
The fleet management system acts as an intermediary between vehicles and charging stations, coordinating assignments and monitoring status. This intermediary layer simplifies infrastructure management by providing centralized control over distributed charging assets, enabling efficient allocation without requiring direct manual management of each station
4Loss of time
If fast charging infrastructure is deployed to reduce recharging time, then fleet readiness improves, but compatibility issues arise with different vehicle types and charging standards
Solution Approach 1:
The system adapts charging parameters dynamically based on vehicle-specific requirements including battery type, maximum charging rate, and connector compatibility. It adjusts charging speed, power delivery characteristics, and station selection to match each vehicle's capabilities, enabling efficient charging across diverse fleet compositions without compatibility issues
