Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery system is specially designed for each vehicle model to achieve maximum output and charge/discharge capacity, then the performance requirements are met, but the manufacturing cost increases
Solution Approach 1:
The patent applies universality by designing a standardized battery system that can be mounted on multiple different vehicle models. The exterior case is designed with universal mounting features that allow adaptation to various chassis types without requiring model-specific custom designs, thereby reducing manufacturing costs while meeting performance requirements through standardized configuration
Solution Approach 2:
The patent utilizes parameter changes by allowing flexibility in the number of battery blocks connected in series or parallel, and by adjusting the output and capacity parameters of each battery block. This enables the same standardized battery system to achieve optimal performance for different vehicle models by changing electrical parameters rather than physical design
2Power
If the battery system is specially designed for each vehicle model, then the output and capacity are optimized, but the design complexity increases
Solution Approach 1:
The exterior case is designed as a universal mounting structure that can accommodate battery blocks in various configurations for different power and capacity requirements. The standardized case design with universal mounting features reduces design complexity while maintaining the ability to optimize output and capacity through different battery block arrangements
3Ease of manufacture
If the battery system uses a standardized design for multiple vehicle models, then the manufacturing cost is reduced, but the adaptation to specific chassis designs becomes difficult
Solution Approach 1:
The patent applies dynamics by making the battery system adaptable through external fixing brackets that can be positioned and adjusted according to specific chassis designs. The standardized exterior case combines with adjustable mounting features, allowing the same battery system to adapt to different vehicle models without requiring custom design for each chassis
