Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a battery pack includes a plurality of battery cells to ensure sufficient capacity and output, then the energy storage capability is improved, but the volume and weight increase making it difficult to move through narrow spaces
Solution Approach 1:
The battery pack is divided into multiple battery modules, each module containing a subset of battery cells. This segmentation allows the overall capacity to be maintained while creating modular units that are easier to handle, transport, and install in narrow spaces compared to a single large battery pack.
2Quantity of substance
If a battery pack has a relatively large volume and heavy weight, then sufficient capacity and output are ensured, but the convenience for carrying and installation deteriorates
Solution Approach 1:
The battery pack structure is segmented into multiple modules that can be independently handled and installed. Each module maintains a manageable size and weight while collectively providing the required total capacity, significantly improving installation convenience in confined spaces.
Solution Approach 2:
The modular design allows battery modules to be nested or stacked within the battery pack housing, enabling compact arrangement that optimizes space utilization while maintaining ease of installation and removal of individual modules.
3Quantity of substance
If the battery pack includes multiple battery modules, then the energy storage capability is improved, but the complexity of assembly and fastening increases
Solution Approach 1:
The battery pack is segmented into standardized modules with uniform interfaces and fastening mechanisms. This standardization reduces assembly complexity despite the increased number of modules, as each module follows the same assembly pattern and can be quickly fastened using consistent methods.
Solution Approach 2:
Multiple battery modules are combined into a unified pack structure with integrated fastening systems. The modular design with standardized interfaces allows for simplified assembly procedures, reducing the overall complexity of assembling multiple modules compared to custom non-modular designs.
4Quantity of substance
If the battery pack is designed for sufficient capacity with multiple battery cells, then the energy output is improved, but the safety risk in case of abnormal situations increases
Solution Approach 1:
The battery pack is divided into multiple independent modules, each containing a subset of battery cells. This segmentation isolates potential failure points, so that an abnormal situation in one module does not necessarily affect other modules, thereby improving overall safety and reliability.
Solution Approach 2:
Fire barriers are introduced as intermediary elements between battery modules and within the battery pack structure. These fire barriers act as protective mediators that prevent flame propagation from one module to another, enhancing safety while maintaining the multi-module configuration for sufficient capacity.
