Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large number of battery cells are mounted to meet capacity requirements, then energy storage capacity is improved, but mounting and fixation complexity increases
Solution Approach 1:
The battery cabinet is divided into multiple battery units, each comprising a battery tray with multiple battery accommodating areas. This segmentation allows systematic arrangement of numerous cells while simplifying mounting operations through modular assembly. Each tray can be independently assembled and then stacked within the cabinet, reducing overall mounting complexity.
Solution Approach 2:
Multiple battery trays are stacked vertically within the cabinet body, with each tray containing multiple battery accommodating areas. This nested arrangement allows efficient use of space while maintaining organized structure. The trays are fixed to the cabinet body through positioning structures, creating a hierarchical nesting system that simplifies both mounting and maintenance.
2Quantity of substance
If battery units are stacked to increase storage capacity, then energy storage capacity is improved, but heat dissipation difficulty increases
Solution Approach 1:
Heat dissipation flow channels are introduced as intermediary structures between battery cells and the cooling system. These channels facilitate uniform heat transfer from multiple battery units to the temperature adjusting device, solving the heat dissipation challenge posed by stacked battery arrangements. The flow channels act as thermal conduits that distribute cooling efficiently throughout the cabinet.
Solution Approach 2:
The temperature adjusting device serves multiple battery units simultaneously through a unified cooling system. Rather than providing individual cooling for each battery unit, the system uses shared flow channels and a central temperature adjusting device to cool all batteries uniformly, reducing system complexity while maintaining effective heat dissipation across all stacked units.
3Quantity of substance
If multiple battery units are arranged in the cabinet, then energy storage capacity is improved, but temperature uniformity deteriorates
Solution Approach 1:
Heat dissipation flow channels serve as thermal intermediaries that distribute cooling uniformly across all battery units. The channels are designed to ensure consistent heat transfer from each battery unit to the temperature adjusting device, maintaining temperature uniformity even as the number of battery units increases. This intermediary thermal pathway prevents temperature gradients that would otherwise develop in stacked configurations.
Solution Approach 2:
The cooling system is designed with localized heat dissipation flow channels that are positioned to contact or proximity each battery unit. This ensures that each local region (battery unit) receives appropriate cooling attention, maintaining uniform temperature distribution across the entire cabinet despite the large number of units. The local quality of cooling is optimized for each battery's specific thermal needs.
