Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounting boxes have complex structures due to the need for precise alignment of components, leading to increased weight and complicated installation processes.
Innovation Solution
A battery mounting box design featuring a pressure relief hole and supporting ribs that form a pressure relief cavity between the tray and the bottom plate, allowing gas discharge through the hole, simplifying installation and reducing weight by eliminating the bottom bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bottom bracket is provided in the box body to support the tray, then the tray can be supported, but the structure becomes complicated and weight increases
Solution Approach 1:
The patent merges the bottom bracket and tray into a single integrated supporting structure. The tray itself is designed with supporting ribs that directly extend from its bottom surface to support the battery module, eliminating the need for a separate bottom bracket. This integration reduces the number of components and simplifies the overall structure while maintaining the required support capability.
Solution Approach 2:
The tray is designed to perform multiple functions: it not only holds the battery module but also provides structural support through its integrated supporting ribs. The supporting ribs are formed as an integral part of the tray, allowing the tray to serve both as a container and a support structure, thereby reducing the need for additional components.
2Strength
If a bottom bracket is provided in the box body to support the tray, then the tray can be supported, but the installation process becomes complicated
Solution Approach 1:
By integrating the supporting ribs directly into the tray structure, the patent eliminates the need for separate assembly steps involving a bottom bracket. The supporting ribs are formed as an integral part of the tray during manufacturing, which significantly simplifies the installation process. During installation, only the tray needs to be placed into the box body, and it automatically provides the required support.
3Strength
If multiple components are provided in the box body, then the support function is achieved, but the weight of the box body increases
Solution Approach 1:
The patent combines the tray and supporting ribs into a single integrated component, reducing the total number of parts. This integration eliminates the weight of the separate bottom bracket while maintaining the necessary support function. The supporting ribs are formed from the same material as the tray, optimizing the use of materials and reducing overall weight.
Solution Approach 2:
The tray is designed to serve multiple purposes: it contains the battery module and simultaneously provides structural support through its integrated ribs. This multi-functionality reduces the need for additional support components, thereby reducing the overall weight of the box body while maintaining adequate support capability.
4Ease of operation
If the tray is directly mounted in the box body, then installation is simplified, but pressure relief is compromised
Solution Approach 1:
The patent integrates the pressure relief cavity directly into the supporting structure of the tray. The supporting ribs are designed to form a cavity between themselves and the box body, which serves as a pressure relief chamber. This integration ensures that the pressure relief function is built into the supporting structure, maintaining both installation simplicity and pressure relief reliability.
Solution Approach 2:
The patent utilizes the space between the supporting ribs and the box body to create a pressure relief cavity. By designing the supporting ribs with specific geometry and spacing, a three-dimensional cavity is formed that can accommodate pressure relief operations. This approach adds a functional dimension to the supporting structure without complicating the installation process.
