Segmented Battery Box Structure for Easier Pack Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of battery packs are complicated due to structural limitations of the battery box, making it difficult to efficiently assemble and disassemble batteries without causing damage.
Innovation Solution
A battery pack design featuring a main frame with detachably connected first and second portions allows for easy assembly and disassembly by connecting the battery to either portion, with additional features like thermally conductive adhesives for stability and heat dissipation, and pressure relief structures for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery box uses a fixed integrated structure, then the structural strength is improved, but the assembly and disassembly complexity increases
Solution Approach 1:
The main frame is divided into a first portion and a second portion that can be detachably connected. The battery is connected to one of these portions, allowing the battery to be removed by detaching only the connected portion rather than disassembling the entire fixed structure. This segmentation resolves the contradiction by maintaining structural integrity through modular design while enabling simplified assembly and disassembly operations.
2Ease of operation
If the battery box uses a detachable main frame structure, then the assembly and disassembly ease is improved, but the structural stability may worsen
Solution Approach 1:
The main frame is segmented into detachable portions that can be connected and disconnected. When connected, these portions form a stable structure sufficient to support the battery. The segmentation allows the structure to be stable during operation while enabling easy disassembly when needed, resolving the contradiction between operational stability and ease of assembly/disassembly.
Solution Approach 2:
The main frame transitions from a static fixed structure to a dynamic detachable structure. The connection between the first and second portions can be established or released as needed, allowing the structure to adapt between a stable connected state during operation and a disassembled state for maintenance or battery replacement, thus resolving the contradiction between stability and ease of operation.
3Ease of operation
If the entire main frame is detached for battery removal, then the battery access is improved, but the time consumption and operational efficiency worsen
Solution Approach 1:
Instead of requiring detachment of the entire main frame, the battery is connected to only one portion (first or second portion). This portion can be detached independently to access and remove the battery, significantly reducing the time and complexity of the operation compared to disassembling the complete main frame structure.
Solution Approach 2:
The battery connection is extracted from the main frame structure by connecting it to a specific detachable portion rather than the entire frame. This extraction allows the battery to be accessed by removing only the necessary portion, minimizing disassembly time and improving operational efficiency while maintaining full battery access capability.
