Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple battery modules are provided to satisfy increased power requirements, then power capacity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple cell stacks into a single integrated module housing with shared cooling channels and structural components. The module housing integrates support walls, cooling channels, and cell stack accommodations into one unified structure, reducing the need for separate framing and support components when multiple modules are assembled together.
Solution Approach 2:
The module housing serves multiple functions simultaneously: it provides structural support, houses cooling channels, accommodates multiple cell stacks, and enables electrical connections through integrated connectors. This multi-functionality reduces the number of separate components needed, simplifying the overall system while maintaining high power capacity.
2Power
If multiple battery modules are assembled to achieve high power, then power capacity is improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the battery system into standardized modular units that can be independently manufactured and then assembled. Each module contains a defined number of cell stacks (e.g., four cell stacks per module) with standardized interfaces, allowing for efficient production and assembly while achieving high overall power capacity.
Solution Approach 2:
The module housing integrates multiple functions into single components, reducing the total number of parts that need to be manufactured and assembled. The cooling channels are formed as integral parts of the housing structure rather than separate components, and the support walls serve both structural and organizational functions.
3Stability of the object's composition
If traditional battery module designs are used, then structural stability is maintained, but component complexity and weight increase
Solution Approach 1:
The module housing combines structural support functions with cooling and cell accommodation functions into a single integrated structure. The support walls are formed as integral parts of the housing rather than separate framing members, reducing component complexity while maintaining structural stability for supporting multiple cell stacks.
4Stability of the object's composition
If additional framing and support components are used for module assembly, then structural stability is improved, but device complexity and weight increase
Solution Approach 1:
The module housing integrates structural support, cooling, and cell accommodation functions into one structure, eliminating the need for additional framing and support components when multiple modules are assembled. The housing walls themselves provide the structural stability needed to support the cell stacks without requiring separate framing members.

AI summary
A battery module includes first and second modules each including a series of cell stacks, each including a series of unit cells arranged in a first direction, and an insulation member insulating at least one unit cell. The battery module also includes a module housing, a coupling part on the module housing configured to couple the module housings of the first and second modules together, and a series of receiving parts in the module housing accommodating the cell stacks. Each receiving part includes a fixed wall around a respective cell stack and having at least a portion that is in contact with the respective cell stack. The coupling part includes a connector configured to electrically connect the module housings of the first and second modules together.
