A hybrid drive module design featuring a housing part with integrated coolant and power connections, a flange for the heat exchanger, and partially integrated coolant lines, allowing for a compact, simple, and flexible assembly that eliminates the need for external coolant lines and enhances space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external coolant lines are used to connect the heat exchanger, then the heat exchanger can be connected to the coolant system, but the assembly complexity increases and installation space is consumed
Solution Approach 1:
The patent combines the heat exchanger mounting function and coolant connection function into a single integrated flange structure. The flange includes both mounting holes for securing the heat exchanger and integrated coolant passages that directly connect to the housing part's coolant system, eliminating the need for separate external coolant lines and reducing assembly complexity.
Solution Approach 2:
The flange structure serves multiple functions simultaneously: it provides mechanical mounting for the heat exchanger, establishes coolant flow paths through integrated passages, and connects to the housing part's coolant system. This multi-functional design reduces the number of separate components needed and simplifies the overall assembly.
2Reliability
If external coolant lines are used, then coolant flow can be established, but installation space is consumed and compactness is reduced
Solution Approach 1:
The coolant passages are nested within the flange structure itself, with the cooling channels formed as cavities or boreholes inside the flange material. This nesting approach allows the coolant flow path to be contained within the existing structural component rather than requiring separate external lines, achieving compact integration.
3Adaptability or versatility
If a unified module design is implemented, then adaptability to different engines and transmissions is improved, but manufacturing complexity increases
Solution Approach 1:
The hybrid drive module is designed as a universal platform that can be adapted to different internal combustion engines and transmission types. The standardized housing part, flange configuration, and coolant system design allow the same module to interface with various powertrain configurations, improving versatility while maintaining manageable manufacturing complexity through standardization.
