Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery modules are stacked to increase energy storage capacity, then the electrical energy storage improves, but the structural stability and gas emission control deteriorate
Solution Approach 1:
The battery pack is divided into multiple battery modules (first battery module, second battery module, third battery module) that are stacked vertically. Each module contains unit batteries arranged in a specific configuration. This segmentation allows the system to achieve higher energy storage capacity while maintaining manageable structural units that can be independently supported and ventilated.
Solution Approach 2:
A plate structure is introduced as an intermediary component between the first battery module and the second battery module. The second plate of the first battery module serves as both a support structure for the unit batteries and a contact surface for the first plate of the second battery module. This intermediary plate provides structural stability and forms part of a duct system for gas emission control.
2Volume of stationary object
If battery modules are closely stacked to improve space utilization, then the energy density improves, but the gas emission pathways are blocked
Solution Approach 1:
The plate structures serve multiple functions simultaneously: they provide structural support for the unit batteries, act as contact surfaces between modules, and form duct pathways for gas emission. The second plate of the first battery module and the first plate of the second battery module are combined to form a duct that allows gas to pass through the stacked modules.
Solution Approach 2:
The plate structures that provide structural support and space utilization are designed to also serve as gas emission pathways. The duct formed by combining plates converts the potential harm of gas accumulation into a beneficial controlled emission system, where the same structural components facilitate both compact stacking and gas venting.
3Strength
If unit batteries are supported by plates to maintain structural integrity, then the structural stability improves, but the gas venting capability deteriorates
Solution Approach 1:
The plates are designed to perform multiple functions: supporting the unit batteries structurally and simultaneously forming duct pathways for gas emission. The second plate of the first battery module supports the unit batteries of the first battery module and contacts the first plate of the second battery module, while the combination of these plates forms a duct for gas emission.
