Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery standardization is implemented to unify external shape and size, then ease of manufacture and installation is improved, but battery properties remain diverse requiring complex control information management
Solution Approach 1:
The system collects battery property information from multiple electric vehicles and uses this feedback to generate appropriate control information. The battery identification device receives battery property information from plurality of electric vehicles, generates control information based on collected data, and provides it back to vehicles, creating a closed-loop feedback system that manages diversity without increasing complexity
Solution Approach 2:
A battery identification device acts as an intermediary between diverse batteries and the electric vehicle control systems. This intermediary collects battery property information, generates appropriate control information, and provides it to vehicles, thereby mediating the interface between standardized physical batteries and their control requirements
2Reliability
If control information is prepared for each battery property variation, then reliability of vehicle operation is improved, but manufacturing burden and time increase significantly
Solution Approach 1:
The battery identification device performs multiple functions: collecting battery property information from various sources, storing it in a database, generating control information based on collected data, and providing it to electric vehicles. This multi-functional approach eliminates the need for separate preparation processes for each battery type, improving productivity while maintaining reliability
Solution Approach 2:
The system uses feedback from actual battery performance data collected from multiple electric vehicles to generate and refine control information. This feedback mechanism allows the system to learn from real-world operation and automatically adapt control parameters, reducing manual preparation burden while ensuring reliable vehicle operation
3Adaptability or versatility
If uncertified batteries are allowed for installation, then adaptability and user choice are improved, but difficulty in ensuring compatibility increases
Solution Approach 1:
The system replaces manual certification and mechanical compatibility checking with an automated information-based system. The battery identification device collects battery property information, processes it through algorithms, and automatically determines compatibility and generates appropriate control information, substituting complex manual detection and measurement processes with automated information processing
