Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed charging stations are installed, then charging infrastructure is provided at specific locations, but accessibility is limited to areas with existing infrastructure and deployment is complex and costly
Solution Approach 1:
The charging system is divided into modular components: mobile charging units that can be independently deployed, each containing its own energy storage and charging equipment. These units can be segmented and distributed to multiple locations without requiring centralized infrastructure installation.
Solution Approach 2:
The charging infrastructure transitions from static fixed stations to dynamic mobile units that can be moved and repositioned as needed. The system adapts to changing charging demands by relocating units to different areas, providing flexible coverage without permanent installation.
2Adaptability or versatility
If mobile charging systems are deployed, then charging accessibility is improved in remote areas, but energy storage capacity must be sufficient to operate independently of grid power
Solution Approach 1:
Multiple mobile charging units are combined and connected through a daisy-chain architecture, where the energy storage systems of individual units are aggregated to provide sufficient total capacity. This merging allows the fleet to operate independently while maintaining adequate energy reserves.
Solution Approach 2:
The mobile charging units are designed with multi-functionality: they can charge electric vehicles, store energy, and connect to form extended charging networks. The same hardware serves multiple purposes, reducing the need for excessive energy storage in each individual unit.
3Productivity
If multiple mobile charging units are connected in daisy chain configuration, then charging network expandability is improved, but system complexity increases
Solution Approach 1:
The charging network is segmented into standardized modular units with uniform interfaces and protocols. Each unit operates independently but can be easily integrated with others through standardized connection points, simplifying the expansion process despite increased network size.
4Area of stationary object
If fixed charging infrastructure is installed in rural areas, then charging coverage is expanded, but installation cost and logistical requirements increase significantly
Solution Approach 1:
The system replaces static infrastructure with mobile charging units that can be transported to and from rural areas using conventional vehicles. This eliminates the need for complex installation processes including electrical grid connections, concrete foundations, and specialized mounting structures.
Solution Approach 2:
The mobile charging units are designed to be self-contained with integrated energy storage, power management, and vehicle charging capabilities. They require no external infrastructure support or complex installation procedures, simply needing transport to the deployment location.
