Battery Pack Reinforcing Layer for Simpler Adhesive Assembly
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 for insulation and rigidity, which increases production costs and complexity.
Innovation Solution
A battery pack design that includes an outer housing, a battery group, a reinforcing layer, 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 while improving rigidity and insulation through channel holes in the reinforcing layer for uniform adhesive distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin plate is used to cover the discharging end for insulation and rigidity, then insulation and flame retardant performance are improved, but device complexity and manufacturing cost increase due to the need for additional positioning structures
Solution Approach 1:
The resin plate is integrated with the battery group to form a unified structure, eliminating the need for separate positioning structures. The resin plate serves multiple functions simultaneously: insulation, flame retardancy, and structural positioning, thereby reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The resin plate is designed to perform multiple functions: electrical insulation, flame retardancy, structural reinforcement, and positioning alignment. This multi-functional design eliminates the need for separate components for each function, reducing assembly complexity and manufacturing cost while maintaining all required performance characteristics.
2Strength
If a resin plate with positioning structure is used, then insulation and rigidity are improved, but assembling time and labor intensity increase
Solution Approach 1:
The positioning structure is merged into the resin plate itself rather than being a separate component. This integration allows the resin plate to provide both structural rigidity and positioning function simultaneously, enabling faster assembly without requiring additional positioning parts or complex alignment procedures.
Solution Approach 2:
The resin plate is pre-formed with integrated positioning structures during manufacturing. This preliminary action ensures that the positioning features are already in place, eliminating the need for time-consuming assembly operations and reducing labor intensity during the battery pack assembly process.
3Reliability
If a fixation structure is used to assemble the resin plate, then fixing reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The fixation function is merged into the resin plate structure itself through integrated positioning features. The resin plate incorporates self-fixing elements that provide reliable fixation without requiring separate fixation components, thereby maintaining fixation reliability while reducing device complexity and manufacturing cost.
Solution Approach 2:
The resin plate is designed with self-fixing capabilities through integrated positioning structures. The plate automatically positions and secures itself to the battery group without requiring external fixation structures, eliminating additional components and simplifying the overall device while maintaining reliable fixation.
