Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed charging system is used, then charging reliability is improved, but mobility and adaptability to different deployment locations deteriorate
Solution Approach 1:
The charging system is divided into modular components including a mobile charging device with detachable charging stations. Each charging station can be independently transported and deployed, allowing the system to maintain reliability through standardized interfaces while achieving mobility through modular segmentation.
Solution Approach 2:
The system transitions from a static fixed charging infrastructure to a dynamic mobile charging platform that can be transported to various deployment locations. The mobile charging device includes movable components and can be repositioned as needed, providing both reliability through consistent charging capability and adaptability through location flexibility.
2Device complexity
If conventional power supply networks are used, then charging infrastructure is simplified, but accessibility to remote field locations deteriorates
Solution Approach 1:
The charging system extracts the power supply capability from the conventional fixed infrastructure and embeds it within a self-contained mobile charging device. This allows the system to operate independently of external power networks, simplifying the infrastructure needed at remote locations while maintaining the ability to charge electrically driven work machines.
Solution Approach 2:
The mobile charging device is designed as a universal charging platform that can serve multiple deployment locations and different types of electrically driven work machines. The standardized charging interfaces and modular design allow a single mobile unit to replace multiple fixed charging stations across various remote locations.
3Reliability
If charging stations are permanently installed, then charging reliability is improved, but ease of maintenance and repair deteriorates
Solution Approach 1:
The charging system uses modular charging stations that can be detached and transported. This segmentation allows individual charging stations to be easily removed for maintenance or repair while the rest of the system remains operational, combining the reliability of installed charging capability with the ease of maintaining removable components.
4Adaptability or versatility
If a mobile charging system is used, then adaptability to different locations is improved, but device complexity increases
Solution Approach 1:
The mobile charging system is segmented into standardized modular components with uniform interfaces. This segmentation reduces the complexity of managing mobility by allowing simple assembly and disassembly of charging stations on the mobile platform, making the system adaptable to different locations without proportionally increasing operational complexity.
Solution Approach 2:
The system uses standardized charging parameters and interfaces across all modular components. This standardization allows the mobile charging system to adapt to different deployment locations while maintaining consistent operational procedures, thereby increasing adaptability without proportionally increasing the complexity of system management.
