Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a completely new product is developed for each specific battery system functionality, then the battery pack can accommodate batteries with different sizes and electronic properties, but the development time and costs increase significantly
Solution Approach 1:
The battery pack is divided into modular components: a standardized housing structure, interchangeable battery modules, and separate electronic control units. This segmentation allows different battery types to be integrated into the same housing without redesigning the entire system, thus improving adaptability while reducing development time for new configurations.
Solution Approach 2:
The housing and electronic cover are designed as universal components that can accommodate multiple battery types and configurations. The standardized interface and mounting structure enable the same housing to serve multiple functions with different battery modules, eliminating the need for new product development for each battery type.
2Adaptability or versatility
If a completely new product is developed for each specific battery system functionality, then the battery pack can accommodate batteries with different sizes and electronic properties, but the development costs increase significantly
Solution Approach 1:
By segmenting the battery pack into standardized housing, interchangeable battery modules, and separate electronic components, the invention allows manufacturers to produce housing and electronic covers in large volumes at economies of scale, while only the battery modules need to be customized. This significantly reduces development and manufacturing costs for different battery configurations.
Solution Approach 2:
The universal housing and electronic cover design enables a single product platform to serve multiple battery types and applications. This multi-functionality reduces the need for multiple product lines and associated tooling, molds, and assembly fixtures, thereby reducing overall development and manufacturing costs.
3Power
If batteries with different electronic properties are integrated into a battery module, then the power levels required for the application can be attained, but a new product design is required for each battery system
Solution Approach 1:
The battery system is segmented into modular battery cells that can be arranged in series or parallel configurations within the standardized housing. This allows different power levels to be achieved by changing the arrangement of identical modular units rather than redesigning the entire product, thus reducing design complexity while maintaining power flexibility.
Solution Approach 2:
The battery module configuration is made dynamic and adjustable, allowing the same housing to accommodate different numbers and arrangements of battery cells depending on the required power level. This dynamic reconfigurability eliminates the need for fixed, application-specific designs, reducing overall product design complexity.
