Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If batteries are used to power electric vehicles and hybrid vehicles, then emissions are reduced and environmental friendliness is improved, but the batteries have limited energy storage capabilities resulting in limited traveling ranges and need for regular recharging
Solution Approach 1:
The system performs preliminary actions by proactively monitoring battery charge levels and automatically planning recharging routes before the battery is depleted. The navigation system pre-identifies charging stations along the vehicle's path and adjusts routing in advance, ensuring continuous operation without interrupting the driver's journey.
Solution Approach 2:
The system implements continuous feedback loops by monitoring battery charge levels, energy consumption patterns, and remaining travel range. This feedback information is used to dynamically adjust navigation routes, estimate arrival times at charging stations, and provide real-time updates to the driver about battery status and planned recharging stops.
2Adaptability or versatility
If recharging stations are made available for electric vehicles, then batteries can be recharged during trips, but there is no effective means to manage and monitor batteries when recharging stations are not available or when power grid fails
Solution Approach 1:
The system applies beforehand cushioning by maintaining a buffer charge level in the battery that exceeds the minimum required for immediate operation. It calculates safe operating ranges that account for potential grid failures or charging station unavailability, ensuring the vehicle retains sufficient energy reserves to reach alternative charging locations or return to base even under adverse conditions.
Solution Approach 2:
The navigation system acts as an intermediary between the battery management system and external charging infrastructure. It continuously evaluates the availability and reliability of charging stations, selects optimal charging locations based on multiple criteria including station reliability, travel time, and battery status, and coordinates recharging operations to maximize vehicle availability while minimizing dependency on any single charging infrastructure.
3Productivity
If batteries operate continuously to provide power for vehicle operation, then transportation is enabled, but batteries are susceptible to heating and overheating which adversely affects operation, efficiency, and long-term viability
Solution Approach 1:
The system implements periodic action by scheduling regular monitoring intervals for battery temperature and adjusting the vehicle's power management strategy accordingly. It incorporates mandatory cooling periods during high-load operation, plans charging stops at locations with cooling capabilities, and adjusts driving routes to include intermediate stops that allow battery temperature management without significantly impacting overall travel time.
