Battery Housing Seal Assembly Using an Auxiliary Positioning Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery housing systems face challenges in accurately positioning and securing flexible seals, leading to potential incorrect sealing, damage, and increased assembly time, which can compromise the reliability and safety of the battery system, especially in critical environments like vehicle batteries.
Innovation Solution
The use of an auxiliary assembly member to temporarily configure and stabilize the seal during assembly, ensuring correct positioning and contact with the seal receiving portion, thereby facilitating reliable sealing and reducing the risk of damage or misalignment, while also potentially reducing the oxygen volume and flammability within the battery housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seal is made flexible and resilient for effective sealing, then sealing effectiveness is improved, but positioning accuracy and assembly reliability deteriorate due to difficulty in maintaining correct orientation and position
Solution Approach 1:
The patent introduces an auxiliary assembly member as an intermediary tool that temporarily holds the seal in the correct position and orientation during assembly. This mediator enables accurate positioning of the flexible seal without requiring complex fixtures or manual dexterity, thereby resolving the contradiction between seal flexibility and positioning precision
Solution Approach 2:
The auxiliary assembly member is designed to pre-position the seal in the correct configuration before the final assembly step. By performing the positioning action in advance through the auxiliary member, the seal is already correctly oriented when the housing portions are joined, eliminating positioning errors that would otherwise occur during the assembly process
2Device complexity
If conventional manual positioning methods are used for the seal, then assembly complexity is reduced, but assembly time increases and risk of incorrect positioning or damage cannot be excluded
Solution Approach 1:
The auxiliary assembly member serves as a simple intermediary tool that dramatically accelerates seal positioning. Instead of complex automated positioning systems, this simple mediator enables rapid and accurate seal installation, resolving the contradiction between assembly simplicity and productivity by providing a low-complexity high-speed solution
3Device complexity
If the seal is handled without auxiliary support, then the number of components is reduced, but the risk of seal damage during assembly increases
Solution Approach 1:
The auxiliary assembly member acts as a protective intermediary that supports the seal during handling and installation. This simple support structure distributes forces and prevents direct contact that could damage the seal, resolving the contradiction between component simplicity and seal protection by introducing a single auxiliary element that provides comprehensive protection
Solution Approach 2:
The auxiliary assembly member provides beforehand cushioning by supporting the seal in advance during the assembly process. This preliminary protection prevents damage before it can occur, allowing the seal to be handled safely without requiring complex protective measures or increasing the number of critical components

AI summary
A battery housing for constructing a drive battery system for a motor vehicle includes a first housing portion and a second housing portion, which are secured to each other in a connection region with a seal which is located therebetween, wherein there is provided an auxiliary assembly member which is located in the inner space formed by the first housing portion and the second housing portion and at least partially on the connection region.
