Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a battery exchange station is implemented with automated devices for removing and replacing batteries, then battery replacement efficiency is improved, but the cost and complexity of the system increases due to the multitude of different battery types
Solution Approach 1:
The patent implements a universal connection system with standardized interfaces that can accommodate multiple battery types. The connection system includes a multi-connection plate with standardized electrical connectors, ventilation ducts, and fixing elements that work across different battery configurations, allowing a single automated device to handle various battery types without requiring multiple specialized devices.
Solution Approach 2:
The connection system is divided into modular components including a multi-connection plate, electrical connectors, ventilation ducts, and fixing elements. This segmentation allows the system to be configured for different battery types while maintaining a standardized interface, reducing the complexity of handling multiple battery types with a single universal device.
2Device complexity
If manual battery replacement is implemented, then the cost and complexity of the system is reduced, but the weight and physical effort required for battery replacement increases
Solution Approach 1:
The patent introduces a universal connection system with standardized interfaces that acts as an intermediary between the battery and the vehicle. This connection system includes fixing elements and mounting mechanisms that enable automated or semi-automated handling, reducing the physical effort required to move heavy batteries while maintaining system simplicity.
3Temperature
If a connection system with multiple ducts for heat transfer fluid is implemented, then battery cooling efficiency is improved, but the complexity of assembly and disconnection operations increases
Solution Approach 1:
The patent combines multiple cooling ducts (cold duct and hot ducts) into a single multi-connection plate assembly. The ducts are pre-positioned and integrated with the electrical connectors and fixing elements, allowing the entire cooling system to be connected or disconnected as a single unit during battery exchange operations, maintaining cooling efficiency while simplifying assembly and disconnection.
Solution Approach 2:
The connection system is pre-configured with ducts, connectors, and fixing elements in their final positions before battery installation. The multi-connection plate is prepared in advance with all necessary connection points, allowing for rapid connection and disconnection during battery exchange without requiring complex alignment or assembly operations.
4Adaptability or versatility
If a universal connection system is designed to accommodate multiple battery types, then adaptability is improved, but the manufacturing precision requirements increase to ensure proper alignment and connection
Solution Approach 1:
The patent implements localized connection points and interfaces on the multi-connection plate that are specifically designed to accommodate variations in battery types. Each connection point has standardized dimensions and tolerances, allowing the system to adapt to different battery configurations while maintaining consistent manufacturing precision requirements for each local interface.
