Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If additional cooling components such as cold plates are used, then temperature regulation effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The housing structure is merged with the cooling path function, where the housing walls themselves form the cooling channels that direct air flow over the battery cells. This integration eliminates the need for separate cold plates or dedicated cooling components, resolving the contradiction by achieving temperature regulation without additional complexity
Solution Approach 2:
The housing serves multiple functions: it provides structural support for the battery cells and simultaneously acts as the cooling system through its integrated cooling path. This multi-functionality allows temperature regulation to be achieved without adding separate cooling components, thereby reducing device complexity while maintaining effective temperature control

If modular clip design is used, then manufacturing efficiency and ease of assembly are improved, but device complexity may increase
Solution Approach 1:
The battery assembly is segmented into modular clips that can be independently manufactured and assembled. Each clip is a discrete unit that can be produced separately and then assembled into the complete battery structure, improving manufacturing efficiency through standardized modular components while managing complexity through systematic design

AI summary
Aspects of a modular clip for an electric battery, a battery module comprising multiple such modular clips, and a battery pack comprising multiple battery modules are provided. The modular clip includes a housing configured to receive a plurality of battery cells. The housing includes a base portion and a first and second wall extending from the base portion of the housing along a length of the housing, wherein the plurality of battery cells are received between the first wall and the second wall. The first and/or second wall forms a cooling path along the length of the housing, e.g., a gap maintained between the plurality of cells and the first/second wall. The battery module may include a regulator and duct to direct/control air flow to the cooling path in each of the modular clips comprised in a battery module.
