Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lead acid batteries are used in vehicles, then reliability is maintained, but energy storage performance and versatility are insufficient
Solution Approach 1:
The patent transitions from lead acid battery chemistry to lithium ion battery chemistry, fundamentally changing the electrochemical parameters of the battery system. This parameter change enables superior energy storage performance, higher voltage output, and greater versatility for modern vehicle applications while maintaining reliability through proper cell configuration and management.
Solution Approach 2:
The battery system is divided into multiple individual cells (e.g., six cells) that can be connected in series or parallel configurations. This segmentation allows flexibility in achieving different voltage and capacity requirements for various vehicle applications, thereby improving versatility while maintaining system reliability through modular design.
2Quantity of substance
If multiple battery cells are connected in series, then voltage and energy storage are improved, but device complexity increases
Solution Approach 1:
Multiple battery cells are combined within a single integrated casing structure, merging what would otherwise be separate components into one unified unit. The casing incorporates terminal structures, cell holders, and protective elements, reducing overall system complexity despite the increased number of cells for higher energy storage.
Solution Approach 2:
The battery casing is designed with multi-functional elements that serve multiple purposes: structural support, cell containment, terminal integration, and protection. This universal design approach handles the complexity of multiple cells through a single versatile component structure, maintaining ease of installation and integration.
3Manufacturing precision
If insert molded terminals are used, then terminal connectivity and manufacturing precision are improved, but manufacturing process complexity increases
Solution Approach 1:
The terminal structures are merged with the battery casing through insert molding, combining two manufacturing operations into one integrated process. This approach achieves precise terminal positioning relative to the casing while eliminating separate assembly steps, thereby improving manufacturing precision without proportionally increasing overall process complexity.
4Adaptability or versatility
If battery trays with adjustable heights are used, then adaptability to different applications is improved, but device complexity increases
Solution Approach 1:
The battery tray system incorporates adjustable height features that allow dynamic reconfiguration for different vehicle applications. This dynamic adaptability enables the same battery design to fit various installation spaces and requirements without requiring completely different battery units, improving versatility while managing complexity through standardized adjustable components.
