Battery Pack Reinforcing Layer Assembly Using Adhesive Flow-Through
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery pack assembly process is labor-intensive and time-consuming due to the need for a resin plate to cover the discharging end, which increases complexity and cost.
Innovation Solution
A battery pack design incorporating an outer housing, a battery group, a reinforcing layer with channel holes, and a fixation adhesive, where the adhesive wraps the reinforcing layer and battery group, eliminating the need for a fixation structure and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin plate is used to cover the discharging end, then insulation and flame retardant performance are improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines the reinforcing layer and the fixation function into a single integrated structure. The reinforcing layer is designed with channel holes that allow fixation adhesive to penetrate, merging the mechanical reinforcement function with the fixation function, thereby eliminating the need for separate fixation structures and reducing assembly complexity
Solution Approach 2:
The reinforcing layer is designed with channel holes (porous structure) that enable the fixation adhesive to flow through and penetrate the layer. This porous design allows the adhesive to reach the battery group surface effectively, ensuring proper fixation while maintaining the structural reinforcement function
2Reliability
If a positioning structure is arranged to assemble the resin plate, then the resin plate can be fixed, but the assembling process becomes time-consumed and labor-intensive
Solution Approach 1:
The patent extracts and eliminates the separate positioning structure from the assembly. Instead of using additional positioning components, the design relies on the reinforcing layer with channel holes and fixation adhesive combination, which simplifies the assembly process and reduces labor requirements while maintaining fixation reliability
Solution Approach 2:
The reinforcing layer with channel holes serves its own fixation function by allowing adhesive penetration. The structure is designed to work with the fixation adhesive in a self-service manner, eliminating the need for external positioning structures and reducing assembly complexity
3Reliability
If a fixation structure is used to fix the reinforcing layer, then the reinforcing layer is secured, but manufacturing cost and assembly difficulty increase
Solution Approach 1:
The patent merges the reinforcing layer and fixation functions into a single integrated design. The channel holes in the reinforcing layer enable the fixation adhesive to penetrate and secure the layer directly, combining the structural reinforcement function with the fixation function and eliminating separate fixation structures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces assembly difficulty, improves manufacturing efficiency, and enhances the fixing effect of the reinforcing layer and battery group, resulting in a more stable and cost-effective battery pack.
Implementation Method 1
By defining channel holes in the reinforcing layer, the fixation adhesive flows through the channel holes to enter the gap between the reinforcing layer and the battery group
