Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery packing process is inconvenient due to the limitations in connecting battery poles, which hinders efficient series and parallel connections.
Innovation Solution
A battery design featuring two opposite large surfaces and four smaller surfaces, with a pole assembly on the large surface and a bent busbar that connects to another battery's pole assembly, facilitating easy electrical connections by being parallel to the smaller surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional battery connection methods are used, then the battery structure is simple, but the connection process is inconvenient and inefficient
Solution Approach 1:
The busbar is divided into multiple segments (first busbar segment, second busbar segment) that can be independently positioned and connected. This segmentation allows each segment to be optimized for specific connection functions, making the overall connection process more convenient while managing structural complexity through modular design
Solution Approach 2:
The busbar is designed with three-dimensional extension, projecting from the battery surface to provide connection interfaces at different spatial levels. This dimensional extension enables convenient connection operations without requiring complex internal routing, as connections can be made at the projected surfaces
2Quantity of substance
If batteries are packed closely to increase energy density, then space utilization improves, but connection accessibility deteriorates
Solution Approach 1:
Connection interfaces are extended to the outer surfaces of the battery through projected busbar segments. This allows batteries to be packed closely in three-dimensional arrangements while maintaining accessible connection points on the battery exterior, resolving the conflict between compact packing and connection accessibility
Solution Approach 2:
The busbar acts as an intermediary element that extends the connection interface from the internal battery structure to the external environment. This mediator allows close battery packing while maintaining accessible connection points through the projected busbar segments that reach outward from the battery surface
3Volume of stationary object
If pole assemblies are positioned on small surfaces, then internal space is maximized, but connection stability decreases
Solution Approach 1:
The busbar extends in three dimensions from the battery interior to the exterior surface, creating a stable connection interface that projects outward. This dimensional extension provides a robust connection point on the battery surface without requiring the pole assembly itself to be positioned on the surface, thus maintaining internal space while ensuring connection stability

AI summary
The disclosure discloses a battery and a battery apparatus. The battery includes two opposite first surfaces and four second surfaces disposed around the first surfaces, a pole assembly and a busbar. An area of the first surface is larger than an area of the second surface. The pole assembly is disposed on the first surface. The busbar is bent into a first segment and a second segment. The first segment is located at a side of the first surface where the pole assembly is disposed and is connected to the pole assembly. The second segment is parallel to or substantially parallel to a second surface and is used for electrically connecting the pole assembly of another battery.
