Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structural strength of batteries is low, leading to potential damage of electrical connection structures during collisions or other events, which can cause thermal runaway and disrupt normal battery function.
Innovation Solution
A battery design incorporating support pieces that space electrical connection surfaces apart from adjacent components by a fixed clearance, enhancing structural strength, preventing collisions, and maintaining insulation and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery structural components are arranged closely to improve space utilization, then the device compactness is improved, but the structural strength and protection of electrical connection portions deteriorate
Solution Approach 1:
The patent introduces support pieces as intermediary components between battery cells and structural components. These support pieces maintain a fixed clearance that prevents direct contact, thereby protecting electrical connection portions while allowing compact arrangement of battery components. The support piece acts as a mediator that resolves the conflict between compactness and protection.
2Productivity
If the battery components are arranged closely to reduce overall size, then the productivity and space efficiency are improved, but the reliability of electrical connection portions deteriorates due to increased collision risk
Solution Approach 1:
The support pieces are pre-installed between battery cells and structural components before final assembly. This preliminary action establishes the protective clearance in advance, ensuring that electrical connection portions are protected from collision throughout the battery's operational life. The protection mechanism is established beforehand rather than requiring complex protective structures.
3Strength
If structural components are added to improve battery structural strength, then the protection of electrical connection portions is improved, but the device complexity and weight increase
Solution Approach 1:
The patent divides the protective function into separate support pieces rather than requiring a complex integrated structural framework. Each support piece is a simple component that provides localized protection at critical interfaces. This segmentation approach reduces overall structural complexity while maintaining adequate protection throughout the battery assembly.

AI summary
A battery and an electrical device are disclosed. The battery includes multiple structural components. The multiple structural components are arranged along a first direction. At least one structural component is a battery row, which includes at least one battery cell. The battery cell includes a first surface provided with an electrical connection portion. The first surface is oriented toward an adjacent structural component; and a support piece. The support piece is disposed between the battery row and the adjacent structural component. The support piece is configured to space the first surface and the adjacent structural component apart by a fixed clearance.
