Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If battery module recharging is performed using current battery technology, then electrical energy is provided to the vehicle, but the recharging process is time-consuming and interferes with vehicle availability
Solution Approach 1:
The battery module is divided into removable segments that can be quickly exchanged. The system includes a first battery module and a second battery module that can be independently removed and installed, allowing rapid replacement without charging the entire battery system, thus reducing recharging time while maintaining energy provision capability
Solution Approach 2:
The system changes the operational parameter from sequential recharging to parallel battery operation. Multiple battery modules can be connected in parallel to provide sufficient electrical energy, allowing one battery to be replaced while another is in use, effectively eliminating downtime and addressing the time loss issue
2Power
If battery module capacity is increased to meet significant power requirements, then power needs are satisfied, but recharging time increases
Solution Approach 1:
The battery system is segmented into multiple modular units (first battery module, second battery module) that can be independently managed. This allows the system to meet high power requirements through parallel connection of multiple smaller modules rather than using a single large-capacity module, enabling faster replacement of individual smaller modules
Solution Approach 2:
Multiple battery modules are designed with universal interfaces and identical specifications, allowing them to perform the same function interchangeably. This multi-functionality enables any battery module to replace another, facilitating rapid swaps and reducing the impact of individual module capacity limitations on overall system power while maintaining quick replacement capability
