Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules require specific side fixing members for structural integrity and heat dissipation, which can be cumbersome and inefficient, especially in high-power applications like electric vehicles where space is limited.
Innovation Solution
A battery module design that eliminates the need for specific side fixing members by using upper and lower fixing plates with heat dissipation holes and vertical insulating members, allowing for effective heat dissipation and sufficient structural strength without additional side fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If specific side fixing members are used to maintain structural integrity, then strength is improved, but device complexity increases
Solution Approach 1:
The patent removes the side fixing members from the battery module structure, extracting the problematic component that added complexity. The upper and lower fixing plates are designed to provide structural integrity without requiring additional side fixtures, thus simplifying the overall device while maintaining strength.
Solution Approach 2:
The upper and lower fixing plates are designed to perform multiple functions: they provide structural support, maintain battery cell alignment, and enable heat dissipation through integrated heat dissipation holes. This multi-functionality eliminates the need for separate side fixing members, reducing device complexity while maintaining structural integrity.
2Temperature
If heat dissipation structures are added to battery modules, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent merges the heat dissipation function with the existing fixing plates by incorporating heat dissipation holes directly into the upper and lower fixing plates. This integration combines structural support and thermal management into a single component, improving temperature control without increasing device complexity.
Solution Approach 2:
The fixing plates serve dual purposes: providing structural integrity and enabling heat dissipation through integrated holes. This multi-functionality allows the same component to address both mechanical support and thermal management needs, avoiding additional complexity from separate heat dissipation structures.
3Reliability
If more fixing members are used to secure battery arrays, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent removes side fixing members from the assembly process, reducing the number of components that need to be manufactured and assembled. The upper and lower fixing plates alone provide sufficient fixation reliability, simplifying the manufacturing process and improving ease of assembly.
Solution Approach 2:
Instead of adding fixing members to the sides of the battery array, the patent inverts the approach by using only upper and lower fixing plates to secure the battery cells. This inverted configuration maintains reliable fixation while significantly simplifying the manufacturing and assembly process.
