Battery End-Wall Reinforcement for Vibration and Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Batteries generate abnormal noise due to shaking of the box wall under dynamic working conditions, which can lead to collisions and deformation, causing structural weakness and noise.
Innovation Solution
A reinforcing member is fixedly connected to the box wall to enhance its structural strength, mitigating shaking and reducing noise by constraining the box wall relative to the box body, and providing insulation protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the box wall is made thinner to reduce weight, then the weight of the battery is reduced, but the structural strength decreases causing shaking and abnormal noise
Solution Approach 1:
The patent combines the box wall material with a reinforcing member material to create a composite structure. The reinforcing member is integrated with the box wall to form a combined structure that provides both weight efficiency and enhanced structural strength, preventing shaking and abnormal noise while maintaining reduced weight.
Solution Approach 2:
The reinforcing member is designed as a separate component that is integrated with the box wall, allowing the box wall to remain thin and lightweight while the reinforcing member provides localized structural support. This segmentation enables the weight and strength functions to be fulfilled by different components.
2Strength
If a reinforcing member is added to the box wall to improve structural strength, then shaking and noise are reduced, but the device complexity increases
Solution Approach 1:
The reinforcing member is merged with the box wall to form an integrated structure. The reinforcing member is positioned and secured within the box wall structure, combining the structural support function with the existing box wall design without requiring separate complex assembly mechanisms.
Solution Approach 2:
The reinforcing member is strategically positioned at specific locations on the box wall where structural support is most needed. This localized reinforcement provides maximum structural benefit with minimal additional complexity, rather than uniformly strengthening the entire box wall.
3Stability of the object's composition
If the reinforcing member is placed on the internal side of the box wall, then it can constrain the battery unit, but it occupies internal space reducing accommodation capacity
Solution Approach 1:
Instead of placing the reinforcing member on the internal side of the box wall to constrain the battery unit, the patent inverts the approach by positioning the reinforcing member on the external side or integrated within the box wall structure. This allows the battery unit to be constrained through the box wall's overall structural rigidity rather than direct internal contact, preserving internal space.
Solution Approach 2:
The constraint function is achieved by enhancing the box wall's structural rigidity in the external dimension through the reinforcing member, rather than using internal components. This dimensional shift allows the battery unit to be constrained through the box wall's overall structural integrity without occupying internal accommodation space.

AI summary
A battery (100) and an electric apparatus are provided. The electric apparatus includes the battery (100). The battery (100) includes a battery unit (10), a box (20), and a reinforcing member (30). The box (20) includes a box body (21) and a first box wall (221) covering an end of the box body (21), and the battery unit (10) is accommodated in a space enclosed by the box body (21) and the first box wall (221). At least part of the reinforcing member (30) is disposed on the first box wall (221), and is fixedly connected to the box body (21). By disposing the at least part of the reinforcing member (30) on the first box wall (221) of the box (20), the structural strength of the first box wall (221) can be improved through the provision of the reinforcing member (30). Furthermore, by fixedly connecting the reinforcing member (30) to the box body (21), the first box wall (221) can be fixed relative to the box body (21) under joint constraint by the reinforcing member (30) and the box body (21). In this way, shaking of the first box wall (221) can be mitigated, thereby reducing abnormal noise in the battery (100).
