Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple battery systems are used to manage different voltage levels, then power supply capability is improved, but vehicle weight increases
Solution Approach 1:
The patent combines multiple battery systems (12V and 48V) into a single integrated battery pack that provides both voltage levels. The battery pack includes a first battery module for 12V output and a second battery module for 48V output, merging what were previously separate systems into one unified structure that reduces overall weight while maintaining both voltage supply capabilities.
Solution Approach 2:
The single battery pack serves multiple functions by providing both 12V and 48V power outputs from one system. The control unit manages different operating modes where the battery pack can supply 12V to accessories, 48V to motors, or both simultaneously, making the system universal and eliminating the need for separate dedicated battery systems.
2Power
If multiple battery systems are used to manage different voltage levels, then power supply capability is improved, but system cost increases
Solution Approach 1:
By merging multiple battery systems into one integrated battery pack, the patent reduces the total number of components that need to be manufactured, installed, and maintained. This consolidation lowers material costs, assembly costs, and ongoing maintenance expenses while still delivering both 12V and 48V power supply capabilities.
3Power
If multiple battery systems are used to manage different voltage levels, then power supply capability is improved, but packaging space is limited
Solution Approach 1:
The patent integrates what would have been separate 12V and 48V battery systems into a single battery pack with a unified housing structure. This consolidation eliminates the space required for multiple separate battery compartments, mounting structures, and associated wiring harnesses, thereby reducing the total volume occupied while maintaining both voltage supply functions.
4Adaptability or versatility
If multiple battery systems are used to manage different voltage levels, then voltage level requirements are met, but device complexity increases
Solution Approach 1:
The battery pack is designed as a universal power source that can output both 12V and 48V through a single control unit. The control unit manages different operating modes (12V mode, 48V mode, and combined mode) within one integrated system, reducing the complexity that would arise from managing multiple separate battery systems with their own control circuits and wiring.
