Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a thermal management component is added to regulate temperature, then the service life of the battery high-voltage module is improved, but the device complexity increases

Engineering Contradiction:
Improveservice life of battery high-voltage moduleVSAvoidcomplexity of box structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The thermal management component is integrated with the box structure by being fixedly connected to the beams, merging two previously separate functions (structural support and thermal management) into a unified design. This reduces the number of independent components while maintaining both structural integrity and temperature regulation capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The beams of the box structure serve dual purposes: providing structural support and serving as mounting structures for the thermal management component. This multi-functional design allows the same structural elements to fulfill multiple roles, reducing overall system complexity.

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

2Volume of moving object

If the thermal management component is arranged in the first accommodating space, then the size of the box in the thickness direction is reduced, but the space utilization becomes more constrained

Engineering Contradiction:
Improvesize of box in thickness directionVSAvoidspace utilization of first accommodating space
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The thermal management component is positioned within the first accommodating space in the thickness direction, utilizing the vertical dimension for thermal management functionality. This allows the component to be integrated without increasing the overall footprint area, effectively using the third dimension for additional functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The thermal management component is nested within the first accommodating space, fitting inside the existing structural boundaries. This nested arrangement allows the thermal management system to occupy space that would otherwise be empty or underutilized, reducing the need for additional external components.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Strength

If the thermal management component is fixedly connected to the beams, then the structural strength is enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvestructural strength of boxVSAvoidease of assembling thermal management component
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The thermal management component is fixedly connected to the beams through integration during the manufacturing process, combining the assembly of structural and thermal management components into a single manufacturing step. This eliminates separate assembly operations and reduces overall manufacturing complexity despite the enhanced structural connection.

Inventive Principle:
Principle #5Merging (Combining)
