Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If battery cells are arranged in a conventional configuration, then the module can accommodate standard cell layouts, but the module size and weight cannot be optimized for lightweight applications
Solution Approach 1:
The patent employs asymmetric cell arrangement where battery cells are positioned at different heights and orientations within the module. Specifically, cells are arranged in staggered rows with alternating positions, creating an asymmetric layout that optimizes space utilization and reduces overall module weight while maintaining structural integrity
Solution Approach 2:
The invention transitions from conventional two-dimensional cell arrangements to a three-dimensional staggered configuration. Cells are positioned at varying vertical levels and horizontal offsets, effectively utilizing the Z-dimension to achieve compact packaging and weight reduction without compromising electrical connectivity or thermal management
2Volume of moving object
If battery cells are closely packed to reduce module size, then compactness is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The patent introduces heat dissipation members positioned between adjacent battery cells in the staggered arrangement. These intermediary components serve as thermal conduits, facilitating heat transfer from cells while maintaining the compact three-dimensional structure. The heat dissipation members act as mediators that enable close cell packing without compromising thermal management
3Adaptability or versatility
If a simple cell arrangement is used, then manufacturing is easier, but adaptability to various device shapes is reduced
Solution Approach 1:
The battery module is divided into multiple independent cell groups arranged in staggered rows, with each group capable of being assembled separately. This segmentation allows the module to be configured in different shapes and sizes by varying the number and arrangement of cell groups, enhancing adaptability while maintaining manufacturing simplicity through modular assembly procedures
