Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If traditional symmetrical battery cells are used, then manufacturing is simple, but space utilization in asymmetrical device casings is poor
Solution Approach 1:
The battery is divided into multiple cell coils with different outer diameters that can be independently configured within the casing. Each cell coil corresponds to a specific region of the asymmetrical casing, allowing optimized space utilization in different areas while maintaining manageable manufacturing complexity through modular assembly
Solution Approach 2:
The patent applies asymmetry by configuring cell coils with different outer diameters to match the asymmetrical casing shape. The first cell coil has a different outer diameter than the second cell coil, enabling both to fit optimally into regions with different height requirements and maximizing overall space utilization in the non-uniform casing volume
2Volume of stationary object
If cell coils with varying outer diameters are configured, then space utilization improves, but manufacturing precision requirements increase
Solution Approach 1:
Instead of manufacturing one complex asymmetrical cell, the patent segments the battery into multiple standard cell coils with different outer diameters. This segmentation allows each cell coil to be manufactured using standard processes with controlled precision, while the varied outer diameters are achieved through selective assembly rather than complex single-piece manufacturing
Solution Approach 2:
The patent changes the parameter of outer diameter across different cell coils to match the casing geometry. By varying the outer diameter parameter of individual cell coils rather than manufacturing one complex shape, the system achieves high space utilization while maintaining manufacturing precision through standardization of individual components
3Power
If multiple cell coils with different configurations are used, then power output can be optimized for device requirements, but device complexity increases
Solution Approach 1:
The patent applies local quality by configuring cell coils with different outer diameters in different locations within the casing based on local space requirements and power density needs. Each region of the battery receives the appropriate cell configuration for its specific constraints, optimizing overall power output while keeping individual cell designs simple and manageable
Solution Approach 2:
The battery structure is segmented into multiple independent cell coils that can be independently configured according to local requirements. This segmentation allows power optimization in different regions without requiring complex integration, as each cell coil maintains its simplicity while the system achieves optimized power output through their combination
