Integrated Battery Housing Layout for Compact Energy Storage Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power supplies have a large number of components, a large volume, high cost, and complex mounting processes due to the use of multiple battery holders and connectors, which also increase the overall size and complexity.
Innovation Solution
The energy storage power supply incorporates a housing with positioning holes for battery cells, uses a pull rod housing to cover electrical connectors, and integrates a retractable pull rod and holder system to simplify assembly, reduce components, and improve space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple battery holders and connectors are used to fix battery cells, then the battery cells are securely fixed and electrically connected, but the number of components increases, leading to large volume, high cost, and complex mounting processes
Solution Approach 1:
The patent merges the battery holder and cover plate into a single integrated housing structure. The housing directly fixes the battery cells through positioning holes and simultaneously provides electrical connection functions, eliminating the need for separate holders and cover plates. This integration reduces the number of components while maintaining secure fixing and electrical connection reliability.
Solution Approach 2:
The housing structure is designed to perform multiple functions simultaneously: it serves as the battery holder, provides positioning holes for securing cells, incorporates electrical connectors for current collection, and acts as the protective cover. This multi-functionality eliminates the need for separate specialized components, reducing overall device complexity.
2Reliability
If a cover plate is used to cover the electrical connectors, then the connectors are protected, but additional components and assembly steps are required
Solution Approach 1:
The housing structure integrates the protective cover function directly into its design. The housing itself serves as the protective enclosure for electrical connectors, eliminating the need for a separate cover plate. This reduces both component count and assembly steps while maintaining connector protection.
3Reliability
If a battery pack is mounted into a housing, then the battery cells are protected and organized, but the overall volume of the energy storage power supply increases
Solution Approach 1:
The housing structure is designed as an integrated unit that combines the battery holder, cover plate, and protective enclosure functions. By eliminating separate battery pack assemblies and their individual housings, the overall volume is reduced while maintaining protection and organization of battery cells.
Solution Approach 2:
The battery cells are directly positioned within the housing structure through positioning holes, eliminating the need for intermediate battery pack containers. The housing itself serves as the outer enclosure, creating a nested arrangement that minimizes empty space and reduces overall volume.
4Reliability
If two battery holders are used to fix both ends of battery cells, then the battery cells are securely fixed, but the number of components and assembly complexity increase
Solution Approach 1:
The housing structure integrates both fixing functions into a single component. The positioning holes in the housing directly secure battery cells at both ends without requiring separate battery holders. This reduces assembly steps and improves productivity while maintaining secure fixing.
