Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile charging device is deployed to charge electric vehicles at various locations, then charging accessibility is improved, but device complexity increases due to multiple functions required
Solution Approach 1:
The mobile charging device is designed to perform multiple functions: it can charge electric vehicles of various makes and models, provide towing services through its enclosed cargo area, and operate independently of the electrical grid using its internal combustion power source. This multi-functionality allows a single device to address diverse charging needs and improve accessibility without requiring multiple specialized vehicles.
Solution Approach 2:
The device incorporates positioning systems and communication interfaces that allow it to dynamically locate stranded vehicles, navigate to their positions, and establish charging connections adaptively. The system can respond to real-time requests and adjust its operations based on the specific needs of different vehicles and locations.
2Adaptability or versatility
If the mobile charging device includes multiple charging ports to accommodate any make or model, then adaptability is improved, but device complexity increases
Solution Approach 1:
The mobile charging device is equipped with multiple charging ports that support various charging standards and connectors, enabling it to charge different makes and models of electric vehicles. This universal compatibility is achieved by integrating multiple port types into a single device, allowing it to adapt to diverse vehicle requirements without needing multiple specialized charging units.
3Adaptability or versatility
If the device functions as both a charging station and a tow truck, then service capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the functions of a charging station and a tow truck into a single mobile device. The enclosed cargo area serves dual purposes: it can transport stranded vehicles for towing services and provide a protected environment for charging operations. This merging of functions allows the device to offer comprehensive service capabilities while reducing the need for separate specialized vehicles.
4Adaptability or versatility
If the mobile charging device operates independently of the electrical grid, then charging availability is improved, but energy consumption increases
Solution Approach 1:
The mobile charging device is equipped with an internal combustion power source that allows it to generate its own electricity independently of the electrical grid. This self-service capability enables the device to operate in remote locations and provide charging services without external power infrastructure, though it consumes energy from fuel combustion to generate and store electrical energy in its battery system.
