Battery Fixation Frame with Integrated Gas Exhaust Ducts

Solution Overview

Problem

Existing electricity storage devices with multiple battery modules face challenges in reducing costs while effectively cooling and exhausting gases, as they require multiple exhaust ducts which increase complexity and costs.

Innovation Solution

A battery fixation frame member with integrated duct structures is designed, featuring a body plate and duct formation members that form exhaust ducts for gas removal from battery modules, reducing the need for multiple ducts and lowering costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple exhaust ducts are provided for cooling battery modules, then gas exhaustion efficiency is improved, but device complexity and cost increase

Engineering Contradiction:

Improvegas exhaustion efficiencyVSAvoidduct structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple exhaust duct functions into a single integrated duct structure formed by the frame member. The frame member itself is shaped to create multiple internal passages that serve as exhaust ducts, merging what would traditionally be separate components into one unified structure. This reduces the number of parts while maintaining the capability to exhaust gas from multiple battery modules simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The frame member serves dual functions: it provides structural support for mounting battery modules and simultaneously acts as the exhaust duct system. The frame member is designed with through-holes and passages that enable gas flow from multiple battery modules, making it a multi-functional component that eliminates the need for separate exhaust duct components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A battery-affixing frame member includes a body plate section and duct-forming members. The duct-forming members are affixed to one surface side of the body plate section and are combined with the body plate section to form gas discharge ducts. The gas discharge ducts are used to discharge gas discharged from the inside of battery modules. The battery-affixing frame member is used to form a battery-affixing member for integrally affixing the battery modules together, the battery modules being arranged on the other surface side of the body plate section.
