Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large batteries are used for energy storage in charging stations, then the energy storage capacity is sufficient, but the batteries become unwieldy and have high voltage levels that are unsafe for laypersons to handle
Solution Approach 1:
The patent divides a large battery system into multiple smaller battery modules, each with safe voltage levels (e.g., 12V or 24V). These modules can be individually handled by laypersons while collectively providing sufficient energy storage capacity when combined in the charging station system.
2Quantity of substance
If batteries are designed for high energy storage capacity, then they can meet diverse energy needs, but adaptability to specific location requirements and energy needs becomes difficult or impossible
Solution Approach 1:
The battery system is segmented into modular units that can be independently configured. Different numbers and types of battery modules can be combined to create customized energy storage solutions tailored to specific location requirements and energy demands.
Solution Approach 2:
The modular battery design allows dynamic reconfiguration of the system. Battery modules can be added, removed, or rearranged to adapt the energy storage capacity and characteristics to changing requirements at different locations or over time.
3Device complexity
If air cooling is used for battery cooling, then the cooling system is simple, but the cooling effectiveness is insufficient during operation
Solution Approach 1:
The cooling system is divided into multiple localized cooling zones, with individual cooling channels or heat sinks for each battery module. This segmentation allows efficient heat dissipation from each module while maintaining overall system simplicity through modular cooling components.
