Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery designs suffer from low space utilization efficiency, which hinders the improvement of energy density due to suboptimal arrangement of battery cells within the housing.
Innovation Solution
A battery array is formed by arranging M*N battery cells in M rows and N columns, with cells in each row oriented in a specific direction and each column oriented perpendicularly, allowing for a compact structure where the maximum size ratio of cells to the array in the perpendicular direction falls within 0.70 to 0.99, enhancing space utilization and energy density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery cells are arranged in a conventional configuration, then the battery structure is simple to manufacture, but the space utilization efficiency is low
Solution Approach 1:
The patent transitions from conventional single-direction or simple two-direction arrangements to a three-dimensional battery array configuration with M rows and N columns, where battery cells are arranged in both first direction (length direction) and second direction (intersecting direction). This multi-dimensional arrangement maximizes space utilization while maintaining manufacturing feasibility through standardized cell positioning.
2Quantity of substance
If battery cells are tightly packed to improve space utilization, then energy density increases, but heat dissipation becomes more difficult
Solution Approach 1:
The patent introduces thermal conductive members as intermediary components positioned between adjacent battery cells in the array. These thermal conductive members facilitate heat transfer from multiple battery cells simultaneously, enabling effective heat dissipation even in tightly packed configurations. The thermal conductive members act as heat sinks and conduits, maintaining energy density while solving the heat management challenge.
3Volume of moving object
If battery cells are arranged in M rows and N columns with specific orientation, then space utilization efficiency improves, but structural complexity increases
Solution Approach 1:
The patent divides the battery array into distinct segments: M rows extending in the first direction and N columns extending in the second direction. Each battery cell is positioned at specific intersections, creating a modular segmented structure. This segmentation allows for systematic arrangement that maximizes space utilization while maintaining clear manufacturing and assembly pathways for each segment.
Solution Approach 2:
The patent employs universal adhesive components that can bond battery cells in multiple orientations and positions within the M*N array configuration. The adhesive serves multiple functions: mechanical bonding, thermal conduction, and structural stabilization. This multi-functional adhesive approach simplifies the overall structure by reducing the need for specialized fixing mechanisms for different cell positions.
