Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the base plate and dividing wall are connected directly without spacing, then structural strength is improved, but cooling system accommodation becomes difficult

Engineering Contradiction:

Improvestructural strengthVSAvoidcooling system accommodation

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The connecting element is divided into a first connecting portion attached to the dividing wall and a second connecting portion attached to the base plate, with an intermediate portion creating spacing between them. This segmentation allows the structure to maintain strength while accommodating cooling systems in the spaced region.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting element acts as an intermediary component between the base plate and dividing wall, providing both mechanical connection and necessary spacing. The intermediate portion of the connecting element serves as a mediator that enables cooling system integration without compromising structural integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the base plate and dividing wall are spaced apart, then cooling system accommodation is simplified, but structural strength decreases

Engineering Contradiction:

Improvecooling system accommodationVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The connecting element is segmented into distinct portions (first connecting portion, intermediate portion, second connecting portion) that separately handle structural connection and spacing functions, maintaining strength while enabling cooling system integration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting element may be constructed from composite materials or multi-material construction to achieve both mechanical strength for structural support and appropriate flexibility for accommodating cooling systems in the spaced region.

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If complex connection methods are used between base plate and dividing wall, then structural stability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The connecting element merges multiple functions (structural connection, spacing, alignment, and cooling system accommodation) into a single integrated component, simplifying manufacturing while maintaining structural stability through its multi-functional design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connecting element is designed as a universal component that performs multiple functions simultaneously: providing structural connection between base plate and dividing wall, maintaining necessary spacing, enabling cooling system integration, and contributing to overall battery device stability, thereby reducing manufacturing complexity and cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If multiple separate components are used for connection, then adaptability is improved, but assembly complexity increases

Engineering Contradiction:

Improveassembly flexibilityVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple functions (connection, spacing, alignment) are merged into a single connecting element, reducing the number of separate components and simplifying assembly while maintaining adaptability for different cooling system configurations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connecting element is designed as a multi-functional universal component that can accommodate various cooling system arrangements while simplifying the overall assembly process through its integrated design, reducing both part count and assembly complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
