Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various product configurations are created to accommodate both serial and parallel connections, then adaptability is improved, but device complexity and product development costs increase
Solution Approach 1:
The connection module is designed with universal terminals that can accommodate both serial and parallel connections through a single standardized interface structure. The module includes multiple terminals arranged to support different connection topologies without requiring separate dedicated connection structures for each mode, thereby achieving multi-functionality in a unified design.
Solution Approach 2:
The connection module incorporates switchable or reconfigurable connection paths that allow the same physical structure to dynamically adapt between serial and parallel configurations. This enables the battery pack to change its electrical topology based on operational requirements without physical reconfiguration or additional components.
2Adaptability or versatility
If various product configurations are created to accommodate both serial and parallel connections, then adaptability is improved, but product development costs increase
Solution Approach 1:
A single universal connection module design serves both serial and parallel connection requirements, eliminating the need to develop and maintain separate product configurations for each connection mode. This standardized approach reduces engineering development costs, tooling requirements, and manufacturing complexity while maintaining full adaptability.
Solution Approach 2:
The connection module is designed as an independent, modular unit that can be universally applied across different battery pack configurations. By segmenting the connection functionality into a standalone module with standardized interfaces, the system achieves adaptability without requiring custom configurations for each application, thereby reducing development costs.
3Ease of operation
If multiple connection configurations are supported, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connection module provides a unified standardized interface that simplifies installation operations while supporting both serial and parallel connections. Installers work with a single connection type and procedure regardless of the desired electrical configuration, improving ease of operation without requiring complex multi-type connectors or installation procedures.
Solution Approach 2:
The connection module enables operational flexibility through reconfigurable internal connection paths that allow the system to switch between serial and parallel modes without requiring physical reconfiguration by the installer. This dynamic capability provides ease of operation while maintaining a simple, fixed physical structure.
