Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If cooling devices are arranged in battery housing parts, then cooling performance is improved, but manufacturing complexity increases and dynamic properties deteriorate

Engineering Contradiction:
Improvecooling performanceVSAvoidmanufacturing complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the cooling function directly into the battery housing structure by forming cooling channels within the housing itself through integral forming or injection molding. This integration eliminates the need for separate cooling devices and assemblies, thereby improving cooling performance while reducing manufacturing complexity. The cooling channels are created as inherent features of the housing geometry rather than as add-on components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery housing is designed to serve multiple functions simultaneously: it provides structural support, protection for battery cells, and integrated cooling. By incorporating cooling channels directly into the housing structure, the same component performs both mechanical and thermal management functions, reducing the overall number of parts and simplifying manufacturing while maintaining effective cooling performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Temperature

If cooling devices are arranged in battery housing parts, then cooling performance is improved, but dynamic properties deteriorate

Engineering Contradiction:

Solution Approach 1:

By integrating cooling channels directly into the battery housing structure through integral forming, the patent creates a unified component that maintains consistent mechanical properties throughout. This merging eliminates interfaces between separate cooling devices and housing, thereby preserving dynamic properties and structural integrity while achieving effective cooling performance.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature
